Field Welding Large Diameter Steel Pipe

Issue:Welding subcontractor or welders are inexperienced with production welding of steel pipe. Remedy:Specifications should require the welding subcontractor to be qualified for the project, such as requiring a minimum experience of three separate projects exceeding 60 dia. x 5000 long and must General Welding Guidelines - MCAAin the Welding Procedure Specification. When higher preheat is required by the applicable construction code (i.e. B31.1, B31.9, etc.), that preheat shall be used for production welding. Welding on metal that is wet is strictly prohibited; wet metal shall be heated until it SPECIFICATION FOR MILD STEEL PIPE - RANHILLSAJ1.1 The specification is applicable to Mild Steel pipes for water supply systems and shall conform to SPAN TS 21827:Part 1:2013 Technical Delivery Requirements and SPAN TS 21827:Part 2:2013 Tube Requirements. 1.2 These specifications will provide necessary information on the product dimension and requirements for the supply of pipes.

Weldability Specifications Industrial Tube and Steel CorporationPipe ordered under this specification shall be suitable for bending, flanging, and similar forming operations, and for welding. When the steel is to be welded, it is presupposed that a welding procedure suitable to the grade of steel and intended use or service will be utilized. Standard Specification for Steel Casing Pipe, Electric 1.1 This specification covers electric-fusion (arc)-welded straight seam or spiral seam steel casing pipe 10 in. (254 mm) and larger in diameter (outside diameter as specified by purchaser) with wall thickness 0.200 in. (5.1 mm) or greater. It shall be permissible to specify and furnish pipe having other dimensions provided such pipe complies with all other requirements of this specification. ASME/ANSI B16 Standards for Pipes and FittingsASME/ANSI B16.28 - 1994 - Wrought Steel Butt-welding Short Radius Elbows and Returns. This Standard covers ratings, overall dimensions, testing, tolerances, and markings for wrought carbon and alloy steel butt-welding short radius elbows and returns. The term wrought denotes fittings made of pipe, tubing, plate, or forgings.
