New Inspar Pipeline Specification Announcement….
- All pipe is to be made of a long hole, surrounded by metal or plastic centered around the hole.
- All pipe is to be hollow throughout the entire length of the pipe, i.e., do not use holes of different length than that of the pipe.
- The inside diameter of the pipe must not exceed the outside diameter of the pipe, otherwise the hole will be on the outside.
- All pipe is to be supplied with nothing in the hole so that the gas, oil, water, or any other stuff can be put inside at a later date.
- All coated pipe should be supplied undamaged, as damage to the coating can be applied at the job site. (Note: special arrangements can now be made with vendors to supply re-damaged coating and this is recommended as it saves the contractor a great deal of time on the site.)
- All pipe over 500 ft. (153m) in length should have the words “Long Pipe” clearly painted on each end, so the pipe crew will know it IS a long pipe.
- Welded strings of pipe over two miles (3.2km) in length must also have the words “Long String” painted in the middle so the lower-in crew will not have to walk the entire length of the string to determine whether or not it is a long string or a short string.
- Flanges should be used on all pipe. Flanges must have holes for bolts quite separate from the big hole in the middle.
- When ordering 90 degree, 45 degree or 30 degree elbows, be sure to specify right-hand or left-hand, otherwise you will end up going in the wrong direction.
- Be sure to specify to your supplier whether you want level, uphill or downhill pipe. If you use downhill pipe for going uphill, the liquid will flow the wrong way.
- All couplings should have either right-hand or left-hand threads. Do not mix the threads, otherwise, as the coupling is being screwed on one pipe, it is unscrewing from the other.
