A pipe fitters test is an assessment used to evaluate the skills and knowledge of individuals in the pipefitting trade. It typically includes both practical and theoretical components, covering topics such as pipe installation, cutting, threading, and welding, as well as reading blueprints and understanding specifications. This test ensures that candidates possess the necessary competencies to work safely and effectively in various Plumbing and HVAC systems. Successful completion often leads to certification or qualification for employment in the industry.
ok what is the inside diameter of a schedule 40 ,8" inch piece of pipe.? explain why pipe is pipe measured o.d and i.d.? 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.
depends on the level of experience really, about £20,000 to about £70k if youre really good at it.
MS pipe refers to mild steel pipe and ERW pipe is electric resistance welding pipe. The difference is ERW is made of very fine hard steel, while MS (black pipe) is made of malleable steel.

Yes, you can often find practice tests or study materials for pipe fitters online, but availability may vary by location and certification requirements. It's important to check with local unions or certification boards for official resources. Additionally, some websites may offer downloadable practice exams or study guides for a fee. Always ensure that the materials are up-to-date and relevant to your specific test.
a plumber is more for residential and commercial... pipe fitters work in an industrial setting with heavy duty piping.
Yes and no. If knowledgeable and trained in both, yes. Without knowledge and training in plumbing, no.

You can find sample pipe fitters tests through various online resources, such as trade school websites or vocational training programs that offer pipe fitting courses. Additionally, organizations like the United Association (UA) or local unions may provide practice tests or study materials. Websites that specialize in trade exam preparation might also offer downloadable sample tests. Checking with local community colleges or apprenticeship programs can also yield useful resources.
Yes, there are online resources and practice tests available for pipe fitters, including those aligned with the National Center for Construction Research (NCCR) standards. These tests typically cover various topics related to pipe fitting, including measurements, codes, and safety practices. You can find them on educational websites, trade association platforms, or specific training programs aimed at preparing candidates for certification. It's advisable to ensure that the practice tests are up to date and relevant to the current NCCR standards.
