Pipe Fitter

A pipefitter is someone who installs, repairs, and maintains piping systems. To be a licensed pipefitter, one must have a four- to five-year apprenticeship from an accredited trade institution. Most US industrial companies require a pipefitter to be licensed.

How do you seal stainless steel pipe thread?

Stainless steel pipe threads are prone to leaking as well as seizing or gulling of the threads. After many years of experience and pressure testing systems up to 7700 PSI I have found this works best.

Apply UNASCO MX-68 Silver Stainless Steel Pipe Thread Sealing Tape to the threads (4-5) wraps is sufficient for smaller pipes. Generally found that covering all the threads 2 layers deep works well.

Step 2

On top of the Teflon apply a layer of SWAK thread sealing compound. Be sure to cover all around the pipe from the starting thread to the half way point of the entire length of thread.

Step 3

Tighten away

Is there a spec for Applying PTFE tape?

PTFE, polytertafluorethylene polymer, known also under the commercial trademark Teflon is a non sticking plastic, soft material which can be used up to temperatures of about 570 Kelvins. When used in making watertight seals on tubing, just tightly wind it on the threat and what is over the necessary amount will be pushed out during tightening because PTFE is very soft.

What are pipe fitter trade test?

newdiv..in the 30 years of my time in the industry.most times the pipefitter test that was given when you hired on a job was made up by the different men or women.running that craft.so one job might have one test with many different questions than the other.taking the test to say you are a tradesmen would have to be what the written test is about.

just like all other crafts give a trade test in there own decipline.

how do you figure the travel for a 45 degree offset.10 inch pipe?

what is the take out on a 6" inch short radius 90 ?

6"pipe flange 150 lb flange how many bolts ?

what is the take off of a 6" 45 degree fitting.

1.those are some of the very simple questions you will find on a pipe fitters test am also nccer certified and that takes a company endorsement to get.and i think 68 or 70 is lowest you may score.that test has a sorted question's.

**ANSWER KEY**

**DISCLAIMER - I did not write the questions above and I seriously doubt that the "pipefitter" who did has ever seen an NCCER pipe test. However the questions which he asks are good, basic, pipe fitting knowledge questions.

1. 8" Nominal pipe size refers to i.d. on pipe up to 12" at which point the nominal pipe size refers to o.d.

2. Since pipe walls have a given thickness (schedule), it is necessary to consider both inside and outside diameter.

3. A 45 degree offset necessarily forms a 45-45-90 triangle with legs A and B being the same length and leg C (the hypotenuse) being the travel of the offset. There are a couple of ways to calculate the travel. The Pythagorean Theorem is easiest to remember...A2 + B2 = C2 Since A and B will always be the same measure in a 45o offset, it is only necessary to be able to measure one of the legs. Of course, remember to always measure from center line to center line of the pipes. Then plug into the formula and you get the travel from the center of 1 45o degree fitting to the other. Remember to subtract the take out for each fitting and you have the cut length for the pipe.

Alternatively, you could also multiply the measure of the offset (A or B) by the number 1.414 and you would get the same result as C in the formula above.

*Note: The pipe size is not really a relevant factor when calculating an offset, except when considering take out and center line measurement.

4. The take out for a 6" short radius 90o fitting is 6" In fact, the take out for all short radius elbows is equal to the pipe size. The take out for long-radius elbows is 1 1/2 x pipe size. So for a six inch long radius 90, the take out would be 9"

5. 8 bolts. The only time this information seems relevant is when you are making your own flanges. But it does seem to be a popular test question. Just remember that the answer to this question (class 150 flanges) is always 4 bolts up to 3" pipe, 8 bolts up to 8" pipe, 12 bolts up to 14" pipe, 16 bolts for 16" and 18" pipe, and 20 bolts for 20" and 24" pipe. Of course if its class 300 or above, just look it up. But honestly, you aren't gonna make many flanges.

6. 3 3/4" The take out for a 45o fitting is 5/8 times the pipe size. Some old pipe fitter will show you a trick of halving the pipe size, then halving that, then halving that and using the first and last number added together, but that's really stupid. Just remember that take out for 90's is 1 1/2 times the pipe size and take out for 45's is 5/8 times the pipe size.

What is a pipelayer or pipefitter?

Plumbers, of a sort. Here's some info from the U.S. Department of Labor. Most people are familiar with plumbers, who come to their home to unclog a drain or install an appliance. In addition to these activities, however, pipelayers, plumbers, pipefitters, and steamfitters install, maintain, and repair many different types of pipe systems. For example, some systems move water to a municipal water treatment plant and then to residential, commercial, and public buildings. Other systems dispose of waste, provide gas to stoves and furnaces, or supply air-conditioning. Pipe systems in powerplants carry the steam that powers huge turbines. Pipes also are used in manufacturing plants to move material through the production process. Specialized piping systems are very important in both pharmaceutical and computer-chip manufacturing. Although pipelaying, plumbing, pipefitting, and steamfitting sometimes are considered a single trade, workers generally specialize in one of the four areas. Pipelayers lay clay, concrete, plastic, or cast-iron pipe for drains, sewers, water mains, and oil or gas lines. Before laying the pipe, pipelayers prepare and grade the trenches either manually or with machines. Plumbers install and repair the water, waste disposal, drainage, and gas systems in homes and commercial and industrial buildings. Plumbers also install plumbing fixtures
