I have come across a problem in the field were a seam welded pipe has been welded end to end ( circumfrential weld) and the seams (longitudinal) are directly apposed to each other on either side of the cicrumfrential weld, I can not find in B31.3 where it states there must be a minimum amount these two longitudinal seams must be separated a certain amount, I have found the clause in AS/NZS 4458,

BS 534 covers carbon steel pipes, joints and specials (bends and other fittings) but is partly replaced by BS EN 10224 (pipe ranging from 26.9 to 2743 mm outside diameter using steel of yield strengths 235, 275 and 355 N/mm 2) and by BS EN 10311 for joints. BS EN 10312 covers stainless steel pipe.Carbon Steel Pipe Omega SteelSeamless Carbon Steel Pipe. Seamless carbon steel pipe has, as its name implies, no longitudinal weld seam. It is, in essence, one solid homogeneous piece of steel. A solid billet is simply heated and then stretched over a series of mandrels until the pipe has Difference between helical welded pipes and longitudinal LONGITUDINAL LINED SEAM LIGHTWEIGHT STEEL PIPEAs for longitudinal welding, the width of the steel plate should be strictly stuck to the diameter of the pipe. Once the steel is cut for rolling, it cannot be changed, which means the diameter of the longitudinal pipe is fixed. While for helical welding, it can achieve various diameters of pipes by rolling the steel plate with different angles. Thus, helical welding can be used to manufacture pipes of
Difference in ERW and SAWL. Straight seam welded steel pipe, according to welding process can be divided into high frequency resistance welding and submerged arc welding, longitudinal submerged arc welded is short for SAWL, high-frequency straight seam resistance welding is short for ERW.ELECTRIC RESISTANCE WELDED PIPES - Meever KonnectionThe High-Frequency Longitudinal Seam Welded Steel pipe is also called ERW steel pipe.

The pipe was first manufactured by rolling steel sheets or plates into shape and riveting the seams. This method of fabrication continued with improve-ments into the 1930s.

Brent, I am in fact referring to the seam weld on the pipe. We had heard pipelines use the 10 and 2 rule so if one of the seams burst the pressure won't push the pipe out of the ground.
