ASTM A106B / API 5LB Specification

API 5L B seamless steel line pipe is a common grade pipe for the oil and gas pipeline transportation systems.

Almost 90% of the petroleum projects adopts API 5L Grade B line pipe. Which including steel pipes manufacturing process in ERW, LSAW, SSAW and seamless. In case in seamless type, the pipe diameters usually below 16” (406 mm), wall thickness in pipe schedule of SCH 40, SCH STD, SCH 80, SCH XS, and to SCH XXS, until SCH 160. Because of the hot rolled manufacturing process, API 5L B seamless steel line pipe usually refer to the pipe that in small and medium diameters, with thick wall thickness. Large diameters and thin thickness line pipe usually refer to the ERW and SAW steel line pipe.

ASTM A234 WPB Specification

ASTM A234 is Standard Specification for steel pipe fittings includes carbon and alloy steel material for moderate and high temperature services. It covers steel fittings of seamless and welded types. Steel Pipe fittings are applied in pressure pipelines and in pressure vessel fabrications. These fittings material consist of killed steel, forgings, bars, plates, seamless or HFW (fusion welded) pipe products, with filler metal added.

ASTM A234 includes wrought carbon steel and alloy steel fittings of seamless and welded construction covered by the latest revision of ASTM B16.9, B16.11, MSS-SP-79, MSS-SP-83, MSS-SP-95, and MSS-SP-97. etc.

As we know, ASTM A234 steel pipe fittings are used in pressure piping and in pressure vessel fabrication, for services at moderate and elevated temperatures. The fittings material in this standard consist of killed steel, forgings, bars, plates, seamless or fusion-welded tubular products with filler metal added.

In this standard it covers the specification of elbows, tees, reducers, caps and cross, it usually adopt butt welding ends.
