Captions paid for by
Discovery communications

00:00:52,551 --> 00:00:54,655
Narrator:
They're called mini g.P.S --
4
00:00:54,655 --> 00:00:57,655
Pint-sized motorcycles
Whose design is identical
5
00:00:57,655 --> 00:00:59,344
To that of
The full-size motorbikes
6
00:00:59,344 --> 00:01:02,689
That race on
The grand prix circuit.
7
00:01:02,689 --> 00:01:06,137
Mini g.P.S are designed
For kids 9 to 12 years old
8
00:01:06,137 --> 00:01:09,448
Who aspire to one day
Race the big bikes.
9
00:01:15,103 --> 00:01:19,000
A mini g.P. Can reach speeds
Of 80 miles per hour.
10
00:01:22,689 --> 00:01:24,655
Its chassis
Is made of steel tubing,
11
00:01:24,655 --> 00:01:26,551
To which they mount
The handlebars
12
00:01:26,551 --> 00:01:30,379
Along with the clutch
And brake levers.
13
00:01:30,379 --> 00:01:33,965
At both the front and back of
The chassis, they attach a fork.
14
00:01:33,965 --> 00:01:36,413
Then, between each fork
And the chassis,
15
00:01:36,413 --> 00:01:38,344
They mount a shock absorber.
16
00:01:44,000 --> 00:01:48,068
With a steel pin,
They mount a wheel on each fork.
17
00:01:48,068 --> 00:01:51,551
The black circle at the center
Is a brake disk.
18
00:01:54,068 --> 00:01:57,034
Next, they install
A brake caliper on each wheel.
19
00:01:57,034 --> 00:01:59,344
When the rider
Applies the brakes,
20
00:01:59,344 --> 00:02:03,310
The caliper grabs the brake
Disk, immobilizing the wheel.
21
00:02:03,310 --> 00:02:06,689
Now mechanics begin assembling
The engine block.
22
00:02:06,689 --> 00:02:09,793
Using a special tool,
They install bearings
23
00:02:09,793 --> 00:02:11,793
That enable the gear shafts
To turn.
24
00:02:17,344 --> 00:02:19,448
The engine has six gears,
25
00:02:19,448 --> 00:02:23,241
Each of which is comprised
Of several steel gears.
26
00:02:23,241 --> 00:02:26,586
These go into the gearbox.
27
00:02:26,586 --> 00:02:28,344
Next comes the gear shifter.
28
00:02:28,344 --> 00:02:30,965
It connects the gears
To the gear pedal
29
00:02:30,965 --> 00:02:34,827
That the rider operates
With his foot.
30
00:02:34,827 --> 00:02:37,172
Next they install
The crankshaft.
31
00:02:37,172 --> 00:02:40,000
The combustion cycle
Rotates the crankshaft,
32
00:02:40,000 --> 00:02:42,862
Which turns the gears.
33
00:02:42,862 --> 00:02:45,275
They close up that side
Of the engine
34
00:02:45,275 --> 00:02:48,206
And assemble and install
The desmodromic spring.
35
00:02:48,206 --> 00:02:50,034
When the rider selects a gear,
36
00:02:50,034 --> 00:02:52,448
This spring keeps it
Locked in position
37
00:02:52,448 --> 00:02:55,000
Until the rider switches gears.
38
00:02:57,413 --> 00:03:00,655
The engine turns a driveshaft
That, via this pinion gear,
39
00:03:00,655 --> 00:03:04,724
Moves a chain
That turns the rear wheel.
40
00:03:04,724 --> 00:03:06,413
On the other side of the engine,
41
00:03:06,413 --> 00:03:08,137
They assemble the primary couple
42
00:03:08,137 --> 00:03:10,862
And the various components
That go into the clutch,
43
00:03:10,862 --> 00:03:13,275
Such as clutch plates
44
00:03:13,275 --> 00:03:16,862
And the springs that stop
And start clutch movement.
45
00:03:24,586 --> 00:03:27,172
When combustion drives
The piston up and down,
46
00:03:27,172 --> 00:03:29,689
It rotates the crankshaft.
47
00:03:29,689 --> 00:03:34,241
The primary couple transmits
Power to the gearbox and clutch.
48
00:03:34,241 --> 00:03:36,724
This is a one-cylinder engine.
49
00:03:36,724 --> 00:03:39,931
They install the piston
That drives the crankshaft,
50
00:03:39,931 --> 00:03:42,724
Then mount the cylinder
Over the piston.
51
00:03:50,172 --> 00:03:52,758
They close up the cylinder
With a cylinder head,
52
00:03:52,758 --> 00:03:55,689
Then mount the spark plug
That ignites the fuel mixture,
53
00:03:55,689 --> 00:03:58,482
Driving the piston up and down.
54
00:03:58,482 --> 00:04:02,000
A head cover
Closes everything up.
55
00:04:02,000 --> 00:04:04,482
Next they install the ignition.
56
00:04:04,482 --> 00:04:08,068
It consists of two magnets
Called a rotor and a stator.
57
00:04:08,068 --> 00:04:11,586
When the rotor turns, it
Generates an electrical charge
58
00:04:11,586 --> 00:04:13,965
That sets off the spark plug.
59
00:04:16,275 --> 00:04:18,620
Time to install
The finished engine.
60
00:04:18,620 --> 00:04:20,724
They mount it to the chassis
With support pins,
61
00:04:20,724 --> 00:04:22,586
Front and back.
62
00:04:28,310 --> 00:04:29,965
Next they install the water pump
63
00:04:29,965 --> 00:04:32,206
That prevents the engine
From overheating
64
00:04:32,206 --> 00:04:35,551
Along with the belt
That drives the pump.
65
00:04:37,275 --> 00:04:39,034
Then they mount the carburetor.
66
00:04:39,034 --> 00:04:41,344
It mixes the fuel
Entering the engine
67
00:04:41,344 --> 00:04:43,896
With just the right amount
Of air.
68
00:04:43,896 --> 00:04:46,724
Next they install
The air filter.
69
00:04:46,724 --> 00:04:50,241
It keeps out debris
That would clog the engine.
70
00:04:50,241 --> 00:04:52,000
Now the exhaust pipe,
71
00:04:52,000 --> 00:04:53,344
The fuel tank,
72
00:04:53,344 --> 00:04:54,482
The seat,
73
00:04:54,482 --> 00:04:55,655
And fairing,
74
00:04:55,655 --> 00:04:58,793
A plastic enclosure
That shields the driver.
75
00:05:02,137 --> 00:05:04,103
The final component is the chain
76
00:05:04,103 --> 00:05:07,379
Connecting the driveshaft
To the rear wheel.
77
00:05:14,344 --> 00:05:16,241
The engine turns the shaft,
78
00:05:16,241 --> 00:05:18,034
Which turns this chain,
79
00:05:18,034 --> 00:05:19,724
Which rotates the rear wheel.
80
00:05:27,551 --> 00:05:30,344
Mini g.P.S come in
Different sizes.
81
00:05:30,344 --> 00:05:35,000
This particular model has
A 50cc, 14-horsepower engine.
82
00:05:35,000 --> 00:05:38,241
Pretty impressive
For a kid's motorcycle.
83
00:05:51,172 --> 00:05:54,137
Narrator: the fig cookie is
One of life's sweet mysteries.
84
00:05:54,137 --> 00:05:56,448
Who hasn't wondered
How they get the figs
85
00:05:56,448 --> 00:05:58,689
In that seamless pastry wrap?
86
00:05:58,689 --> 00:06:02,310
It turns out that the automated
System for producing fig cookies
87
00:06:02,310 --> 00:06:04,965
Actually dates back to 1891,
88
00:06:04,965 --> 00:06:08,758
And it's what makes the
Fig cookie a snacking success.
89
00:06:14,103 --> 00:06:16,931
Fig cookies are a modern way
Of packaging a fruit
90
00:06:16,931 --> 00:06:19,551
Which has been consumed
For millennia.
91
00:06:21,965 --> 00:06:25,620
Making the fig cookie's pastry
Wrap begins with bags of sugar,
92
00:06:25,620 --> 00:06:29,241
Which they empty
Into a big mixer.
93
00:06:29,241 --> 00:06:31,551
A couple of buckets
Of corn syrup follow.
94
00:06:33,275 --> 00:06:36,000
Then they add
An emulsifier called lecithin
95
00:06:36,000 --> 00:06:38,000
And some vanilla flavoring.
96
00:06:40,275 --> 00:06:43,137
The bowl tilts up
For a quick mixing.
97
00:06:44,827 --> 00:06:47,000
A worker adds
Organic bread flour
98
00:06:47,000 --> 00:06:50,413
And leavening ingredients
To the mix.
99
00:06:50,413 --> 00:06:52,758
They reactivate the mixer,
100
00:06:52,758 --> 00:06:56,000
Which blends everything
Into a thick, sticky batter.
101
00:06:58,034 --> 00:06:59,517
Once properly mixed,
102
00:06:59,517 --> 00:07:02,965
They transfer the batter
Into a large holding tank.
103
00:07:06,551 --> 00:07:09,517
Meanwhile,
They prepare the fig filling.
104
00:07:09,517 --> 00:07:12,931
A worker loads big blocks
Of figs into a mixer,
105
00:07:12,931 --> 00:07:15,413
Then adds a generous amount
Of crumbled cookies
106
00:07:15,413 --> 00:07:18,413
For texture and flavor.
107
00:07:23,137 --> 00:07:25,137
They mix the two ingredients,
108
00:07:25,137 --> 00:07:29,068
Then pour in corn syrup
To add moisture and sweetness.
109
00:07:29,068 --> 00:07:33,482
They add some salt and give
The batch another quick mix.
110
00:07:35,034 --> 00:07:39,724
They sweeten the fig mix some
More by adding plenty of sugar.
111
00:07:39,724 --> 00:07:43,724
And now the jam for the center
Of the fig cookie is complete.
112
00:07:45,965 --> 00:07:49,172
The fig jam and the pastry
Are now positioned for a merger.
113
00:07:50,758 --> 00:07:52,379
It will be a neat trick,
114
00:07:52,379 --> 00:07:55,275
And a special piece of equipment
Makes it possible.
115
00:07:58,000 --> 00:08:01,000
It's essentially a funnel
Within a funnel.
116
00:08:01,000 --> 00:08:04,241
Rollers press the jam
Through the inner funnel
117
00:08:04,241 --> 00:08:06,931
While pushing the pastry
Through the outer one,
118
00:08:06,931 --> 00:08:10,620
Encasing the fig filling
In a seamless pastry jacket.
119
00:08:16,655 --> 00:08:19,137
Here's the process in action.
120
00:08:19,137 --> 00:08:22,206
The system generates long rows
Of fig-filled dough,
121
00:08:22,206 --> 00:08:26,172
And that's how they get
The fig jam in the pastry.
122
00:08:30,931 --> 00:08:34,034
Next a technician
Carves through the dough
123
00:08:34,034 --> 00:08:36,965
And removes a few uncooked
Fig cookies.
124
00:08:39,931 --> 00:08:42,000
It's time for a quick weigh-in.
125
00:08:42,000 --> 00:08:44,896
This confirms
That this batch of fig cookies
126
00:08:44,896 --> 00:08:48,586
Will be exactly the right size.
127
00:08:48,586 --> 00:08:52,103
Now it's into an oven that's
Longer than a bowling alley.
128
00:08:52,103 --> 00:08:55,931
It bakes and browns
The fig-filled ribbons of dough.
129
00:09:03,482 --> 00:09:06,379
Here, a roller compresses
The baked cookies
130
00:09:06,379 --> 00:09:10,137
So they'll fit into
Packages later.
131
00:09:10,137 --> 00:09:11,689
An ultrasonic frequency
132
00:09:11,689 --> 00:09:14,310
Makes this blade vibrate
For a clean cut
133
00:09:14,310 --> 00:09:18,620
As it carves the rows of
Fig-filled pastry into cookies.
134
00:09:18,620 --> 00:09:21,896
The fig cookies are still
A bit warm from baking,
135
00:09:21,896 --> 00:09:25,068
So they now chill out
On a trip through a freezer.
136
00:09:25,068 --> 00:09:26,206
This cooldown
137
00:09:26,206 --> 00:09:28,379
Avoids condensation problems
After packaging,
138
00:09:28,379 --> 00:09:30,896
Preventing mold growth.
139
00:09:33,862 --> 00:09:37,103
The trip through the freezer
Also firms up the fig cookies
140
00:09:37,103 --> 00:09:40,137
So they're less likely
To crumble during handling.
141
00:09:44,586 --> 00:09:46,034
As she packs them,
142
00:09:46,034 --> 00:09:49,000
This worker examines each
Fig cookie for imperfections,
143
00:09:49,000 --> 00:09:53,241
And there's not one reject
In the lot.
144
00:09:58,655 --> 00:10:00,482
The next step is packaging,
145
00:10:00,482 --> 00:10:03,379
Where a machine parcels up
The snacks.
146
00:10:03,379 --> 00:10:06,000
It moves trays full
Of fig cookies
147
00:10:06,000 --> 00:10:08,206
Into a sleeve of metallic film.
148
00:10:13,206 --> 00:10:17,931
Finally, rotating jaws heat-seal
The package at both ends.
149
00:10:24,827 --> 00:10:29,000
It's taken about an hour to make
This package of fig bars,
150
00:10:29,000 --> 00:10:31,482
And it's about time
For a snack break.
151
00:10:31,482 --> 00:10:32,931
If the crowd is hungry,
152
00:10:32,931 --> 00:10:35,689
The whole package
Could be gone in minutes,
153
00:10:35,689 --> 00:10:38,724
But that's the way
The cookie crumbles.
154
00:10:50,482 --> 00:10:53,000
Narrator: thinking inside
The box can be a good thing
155
00:10:53,000 --> 00:10:55,068
If you want to organize
Your tools,
156
00:10:55,068 --> 00:10:58,000
And of course we're referring
To the toolbox.
157
00:10:58,000 --> 00:11:00,620
Proper tool storage
Keeps any work site
158
00:11:00,620 --> 00:11:02,965
Running smoothly
And efficiently,
159
00:11:02,965 --> 00:11:05,965
And today you can really go big
On the concept
160
00:11:05,965 --> 00:11:09,344
With units designed
For mechanics and other pros.
161
00:11:13,827 --> 00:11:15,724
With a professional toolbox,
162
00:11:15,724 --> 00:11:18,862
You'll never have to rummage
Around for the tool you need.
163
00:11:18,862 --> 00:11:21,172
There's a place
For practically everything
164
00:11:21,172 --> 00:11:23,551
In one of these mega
Tool chests.
165
00:11:26,344 --> 00:11:29,620
It starts with a coil
Of heavy-duty steel.
166
00:11:29,620 --> 00:11:34,000
It unwinds into a punch press
That cuts the metal into panels
167
00:11:34,000 --> 00:11:37,034
And punches holes
For later assembly.
168
00:11:39,931 --> 00:11:41,379
Each of these panels
169
00:11:41,379 --> 00:11:44,310
Will be transformed into
A toolbox drawer.
170
00:11:46,827 --> 00:11:50,724
They feed the panels into
An automated bending machine.
171
00:11:50,724 --> 00:11:52,724
It folds them on three sides
172
00:11:52,724 --> 00:11:55,862
To create the back
And sides of the drawer.
173
00:11:58,551 --> 00:12:00,655
It also folds over the rim.
174
00:12:00,655 --> 00:12:04,551
This adds strength to the drawer
And gives it a smooth edge.
175
00:12:08,310 --> 00:12:11,586
The assembler slides
The front panel onto the drawer,
176
00:12:11,586 --> 00:12:14,724
Then an automated welding gun
Reinforces the seams
177
00:12:14,724 --> 00:12:17,379
And secures part
Of the lock mechanism.
178
00:12:20,931 --> 00:12:22,827
To build the toolbox cabinet,
179
00:12:22,827 --> 00:12:28,379
A worker arranges stiffeners and
Lock-bar grids on the back wall.
180
00:12:28,379 --> 00:12:33,793
Then it's over to a lineup
Of computerized welding guns.
181
00:12:33,793 --> 00:12:38,000
These guns fuse the stiffeners
And grids to the panel.
182
00:12:38,000 --> 00:12:40,344
Each part gets numerous welds
183
00:12:40,344 --> 00:12:44,448
To ensure the unit
Really holds up.
184
00:12:44,448 --> 00:12:47,000
The cabinet's side walls
Are next.
185
00:12:47,000 --> 00:12:49,448
Workers prop them up
With supports
186
00:12:49,448 --> 00:12:52,344
As they weld the panels
To the back wall.
187
00:12:56,379 --> 00:12:59,448
With the toolbox right side up,
They install the top.
188
00:13:04,034 --> 00:13:06,068
They turn the cabinet around
189
00:13:06,068 --> 00:13:07,827
And, working from
The open front,
190
00:13:07,827 --> 00:13:10,655
Slide the lock bars
Into their slots.
191
00:13:13,724 --> 00:13:15,931
They then build
The front framework
192
00:13:15,931 --> 00:13:19,172
And weld ledges for the drawers
To the support grid.
193
00:13:21,689 --> 00:13:24,379
They add a panel
To the bottom end of the cabinet
194
00:13:24,379 --> 00:13:26,862
And weld the entire perimeter.
195
00:13:30,896 --> 00:13:32,896
Now it's into the paint booth,
196
00:13:32,896 --> 00:13:36,896
Where spray guns coat everything
In a layer of powder paint.
197
00:13:36,896 --> 00:13:39,758
The paint is tough
And solvent-resistant
198
00:13:39,758 --> 00:13:43,896
So it will hold up to oil spills
In a garage environment.
199
00:13:48,896 --> 00:13:51,137
They install the rest
Of the locking mechanisms
200
00:13:51,137 --> 00:13:53,551
On the front of the cabinet.
201
00:13:53,551 --> 00:13:58,655
Then, using a guide, press the
Adhesive-backed logo into place.
202
00:14:01,034 --> 00:14:02,862
They now snap the drawer slides
203
00:14:02,862 --> 00:14:05,793
Into holes
On the cabinet's side walls.
204
00:14:05,793 --> 00:14:09,586
These slides are equipped
With roller bearings
205
00:14:09,586 --> 00:14:13,172
That will enable the drawers
To open and close smoothly.
206
00:14:17,448 --> 00:14:19,068
Here they make use of the holes
207
00:14:19,068 --> 00:14:23,344
Punched into the drawers
Earlier.
208
00:14:23,344 --> 00:14:27,137
A quick click, and the drawers
Are fastened to the sides.
209
00:14:31,896 --> 00:14:34,000
The drawers come in
A range of sizes
210
00:14:34,000 --> 00:14:37,241
To accommodate tools
Of different proportions.
211
00:14:39,310 --> 00:14:42,517
The shallow compartments will
Hold wrenches and screwdrivers,
212
00:14:42,517 --> 00:14:46,896
While the larger ones have been
Made for the big power tools.
213
00:14:53,793 --> 00:14:56,379
Workers now encase
This mega tool chest
214
00:14:56,379 --> 00:14:58,655
In plastic and cardboard.
215
00:15:00,655 --> 00:15:03,655
But this job
Is not quite wrapped up.
216
00:15:03,655 --> 00:15:05,827
They tip the unit on its side
217
00:15:05,827 --> 00:15:08,965
And send it down the line
To get wheels.
218
00:15:08,965 --> 00:15:12,862
The prepackaging prevents dents
And scratches along the way.
219
00:15:14,758 --> 00:15:18,000
A worker bolts casters
On each corner of the cabinet
220
00:15:18,000 --> 00:15:20,896
To allow it to be easily
Moved around in a garage
221
00:15:20,896 --> 00:15:23,344
Or any other work site.
222
00:15:23,344 --> 00:15:26,275
Add-ons can be purchased
For these tool chests,
223
00:15:26,275 --> 00:15:29,413
So the storage possibilities
Are virtually endless.
224
00:15:29,413 --> 00:15:31,620
That's an organizational
Approach
225
00:15:31,620 --> 00:15:34,344
You can't really mess with.
226
00:15:49,413 --> 00:15:52,689
Narrator: natural gas
And crude oil travel worldwide
227
00:15:52,689 --> 00:15:55,413
Through underground
And undersea pipelines.
228
00:15:55,413 --> 00:15:56,620
These rugged pipes
229
00:15:56,620 --> 00:15:59,034
Are manufactured
In straight lengths,
230
00:15:59,034 --> 00:16:02,689
But of course a pipeline's route
Never runs in a straight line,
231
00:16:02,689 --> 00:16:05,034
So every turn
Or change in elevation
232
00:16:05,034 --> 00:16:07,931
Requires a piece of pipe
That's bent.
233
00:16:11,655 --> 00:16:14,827
This factory specializes
In bending steel pipe,
234
00:16:14,827 --> 00:16:19,068
Which is manufactured
In straight lengths.
235
00:16:19,068 --> 00:16:22,172
A piece of pipe
Is typically 40 feet long
236
00:16:22,172 --> 00:16:24,000
And weighs up to 20 tons,
237
00:16:24,000 --> 00:16:25,448
So workers use a crane
238
00:16:25,448 --> 00:16:28,206
To move it from one operation
To the next.
239
00:16:31,827 --> 00:16:35,103
The first stop is a blasting
Machine that cleans the pipe.
240
00:16:39,586 --> 00:16:41,000
To heat and bend properly,
241
00:16:41,000 --> 00:16:43,724
The surface must be clean
And uniform,
242
00:16:43,724 --> 00:16:47,241
But pipe usually arrives
At the plant dirty
243
00:16:47,241 --> 00:16:49,379
And wearing a coat of varnish
To prevent rusting
244
00:16:49,379 --> 00:16:51,413
During transport and storage.
245
00:16:55,137 --> 00:16:58,448
The blasting machine shoots
Grains of steel at high pressure
246
00:16:58,448 --> 00:17:01,793
For about an hour.
247
00:17:01,793 --> 00:17:05,793
The pipe exits with its surface
Now clean and smooth.
248
00:17:07,862 --> 00:17:10,551
From the blaster,
It's on to the blender,
249
00:17:10,551 --> 00:17:13,793
Which heats the pipe to about
1,800 degrees fahrenheit,
250
00:17:13,793 --> 00:17:17,379
Then makes the bend.
251
00:17:17,379 --> 00:17:21,827
A technician installs
The induction-heating coil.
252
00:17:21,827 --> 00:17:24,448
Induction heating allows
Greater temperature control,
253
00:17:24,448 --> 00:17:28,344
Which is key to preserving
The quality of the steel.
254
00:17:28,344 --> 00:17:31,551
The coil doesn't actually
Touch the pipe,
255
00:17:31,551 --> 00:17:34,655
Because that would cause
A short circuit.
256
00:17:34,655 --> 00:17:38,586
Next they clamp a pivoting arm
To one end of the pipe,
257
00:17:38,586 --> 00:17:41,448
Then power up the coil.
258
00:17:41,448 --> 00:17:46,206
This generates a magnetic field
That produces intense heat.
259
00:17:46,206 --> 00:17:49,241
Cold-water jets confine it
To the target area.
260
00:17:52,724 --> 00:17:55,241
As a technician monitors
And measures,
261
00:17:55,241 --> 00:17:56,724
The arm pulls the pipe
262
00:17:56,724 --> 00:17:58,896
Through the hot coil
At a specific speed,
263
00:17:58,896 --> 00:18:03,620
Curving the softened steel
To the same angle.
264
00:18:03,620 --> 00:18:06,517
Water cools the pipe
At a controlled rate,
265
00:18:06,517 --> 00:18:10,413
A process called quenching.
266
00:18:10,413 --> 00:18:13,344
They must control heating
And cooling precisely.
267
00:18:13,344 --> 00:18:16,068
Otherwise,
The steel will weaken.
268
00:18:20,931 --> 00:18:23,655
Once the pipe exits the bender,
269
00:18:23,655 --> 00:18:26,379
Workers verify the angle again.
270
00:18:29,448 --> 00:18:32,206
They also verify
The pipe's dimensions
271
00:18:32,206 --> 00:18:34,793
To make sure the bending process
Didn't distort them.
272
00:18:39,862 --> 00:18:42,103
Now they cut off
The straight ends,
273
00:18:42,103 --> 00:18:44,655
Leaving just the curved portion.
274
00:18:58,310 --> 00:19:01,758
Next the pipes go into
A furnace for tempering,
275
00:19:01,758 --> 00:19:04,724
A 10-hour reheating
And cooling cycle.
276
00:19:04,724 --> 00:19:08,655
This relieves stress in
The steel that bending created.
277
00:19:11,206 --> 00:19:14,448
After tempering,
Pipes designed to go underwater
278
00:19:14,448 --> 00:19:16,965
Go through a second quenching.
279
00:19:16,965 --> 00:19:19,379
This gives the steel
The right properties
280
00:19:19,379 --> 00:19:22,310
To withstand
Deep-seawater pressure.
281
00:19:25,482 --> 00:19:28,068
Then, using an ultrasonic gauge,
282
00:19:28,068 --> 00:19:30,758
Workers measure the thickness
Of the pipe walls,
283
00:19:30,758 --> 00:19:32,931
Which changes with bending.
284
00:19:35,517 --> 00:19:38,034
After another trip
Through the blast cleaner,
285
00:19:38,034 --> 00:19:40,241
Workers apply a liquid
That highlights
286
00:19:40,241 --> 00:19:44,344
Even the most minute surface
Cracks that bending can induce.
287
00:19:44,344 --> 00:19:47,241
If they find cracks,
They scrap the pipe.
288
00:19:50,827 --> 00:19:53,586
But defects are rare
Because the factory
289
00:19:53,586 --> 00:19:57,103
First performs test bends
On sample pieces of pipe,
290
00:19:57,103 --> 00:20:01,965
Then subjects those samples
To a battery of tests.
291
00:20:01,965 --> 00:20:04,827
The lab measures dimensions
And wall thickness,
292
00:20:04,827 --> 00:20:07,517
Then tests how much weight
The sample can support
293
00:20:07,517 --> 00:20:09,344
Before collapsing
294
00:20:09,344 --> 00:20:14,103
And how much stretching it can
Withstand before snapping.
295
00:20:21,482 --> 00:20:23,206
Back on the factory floor,
296
00:20:23,206 --> 00:20:25,862
The pipe goes through
Another blasting.
297
00:20:25,862 --> 00:20:27,275
Then workers heat it
298
00:20:27,275 --> 00:20:30,655
And spray on a protective
Coating that prevents corrosion.
299
00:20:30,655 --> 00:20:33,344
It melds to the hot pipe.
300
00:20:33,344 --> 00:20:35,586
Once the pipe cools,
301
00:20:35,586 --> 00:20:38,793
They stencil on
Technical specifications.
302
00:20:38,793 --> 00:20:40,482
Then these pipe bends
303
00:20:40,482 --> 00:20:43,448
Go off to join
Their straight counterparts.
