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.
High Frequency Electric Weld (ERW) Line Pipe and They are produced by continuously forming coiled hot rolled strip into a tube and welding the longitudinal seam
What Is Selective Seam Weld Corrosion. Selective seam weld corrosion External and internal corrosion interacting with a longitudinal defective pipe seam
Useful Information about Spiral Weld Pipe. The Myths and the Facts about Spiral Pipe The pressure carrying capacity of spiral pipe and straight seam pipe is the same.

Saginaw Pipe, steel pipe chart for sizes 8 inch to 18 inch OD, structurals, schedule 4, Welded and seamless steel pipe 8 to 18 NPS : Dimensions and weights
Straight seam welded pipe is made of steel plate or steel strip after bending forming, and then through welding. Divided into the form of the weld seam welded pipe and spiral welded pipe by the welding forming method.
Do your tubes seam good enough? Using eddy current testing to make sure. The Tube & Pipe Journal October/November 1999 August 16, 2001 By: Tim Brown Eddy current testing offers several features that makers of welded tube may find to their liking—in particular, high throughput speeds and sensitive flaw detection.
Longitudinal welded pipes with enhanced fatigue strength The loads which occur can be so high that a conventional welded pipe automatically seam welded
Seamless pipe vs Welded pipe. flattened along the weld; then turned the seam pipe Repeat the above steps to make the weld The curved inner diameter is 180 °.
Longitudinal Seam Welders - External, Internal, Flat Plate and Elevating Seam welders produce a linear weld across a longitudinal seam such as two flat plates or a tubular pipe.
This specification covers straight seam and spiral butt seam welded unannealed austenitic stainless steel tubular products intended for low and moderate temperatures and corrosive service where treatment is not necessary for corrosion resistance. The tubular products shall be made from flat-rolled
