Leaks at toes of weld when hydraulically tested with water psi.
Note 2 — This provision is not intended to prohibit the cold bending of Grade B pipe. Which in awtm, a single-pass application is less then desireable for a leak proof system. Several things pop up flags in your message. We appreciate your input.
ASTM A and ASME SA Carbon Steel Pipes and Tubes
My best guess is that hydrogen from the coating, along with the hardness of the HAZ is causing underbead cracks at the toes of the weld.
Any suggestions for weld procedure would be appreciated. We advise that you only use the original value or one of its raw conversions in your calculations to minimize rounding error.

ASTM A135 and ASME SA135 Carbon Steel Pipes
Steel may be cast in ingots or may be strand cast. The suitability of pipe for various purposes is somewhat dependent upon its dimensions, properties, and conditions of service, so that the purpose for which the pipe is intended should be stated in the order. Please contact us at webmaster matweb.
Historical Version s – view previous versions of standard. This abstract is a brief summary of the referenced standard. Specimens of the steel pipes are subject to flattening test and hydrostatic test. Property Data This page displays only the text of a material data sheet.
Some of the pipes are painted and some are coated with a ‘varnish’ like material. This w135 covers two grades of electric-resistance-welded steel pipe intended for conveying gas, vapor, water or other liquid. Tensile and chemical requirements of the steel are provided. Combining values from the two systems may result in non-conformance with the standard.
