Laitram machines are used to de-head and de-vein shrimp. These machines can also peel, steam, and chill shrimp.

How is industrial harmony achieved?

When the workers and Management of any Industry work hand in hand without any friction, Industrial Harmony is achieved. Even if there are differences of opinion, if the same is sorted out in an atmosphere of mutual trust and confidence, the industrial harmony can be achieved.


Where can you download a pre employment test for pipe fitters?

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.
