Product Description
B16.9 A234 Wp11 Cl1 Alloy Steel Pipe Fitting End Cap
ASTM A234 covers wrought carbon steel and alloy steel fittings of seamless and welded construction covered by the latest revision of ASME B16.9, B16.11, MSS-SP-79, MSS-SP-83, MSS-SP-95, and MSS-SP-97. These fittings are for use in pressure piping and in pressure vessel fabrication for service at moderate and elevated temperatures.
ASTM A234 WP11 Pipe Fittings are essential to the petroleum as well as the oil industry and they do not bear porosity. This is because; they are made by a one metal body and can be believed in for serious transmission methods. Besides, these alloy steel WP11 lap joint stub-ends that are corrosion resistant and re-usable even give instant dismantling while testing. Moreover, we provide the wide variety steel pipe fittings like end pipe cap, tee, reducer, stub-ends, elbow, cross and alloy steel.
