Description

ASTM A234 WPB Carbon Steel Seamless Fittings Elbow Rust Proof Black Oil Surface

ASTM A234 (ASME SA234) is standard specification of carbon and alloy steel pipe fittings for moderate and high temperature services. Common use material are ASTM A234 Grade WPB, WPC, WP5, WP9, WP11, WP22 and WP91. It covers the butt-welded pipe fittings of Elbow, Tee, Reducer, Cap and Cross, and some socket welding, threaded pipe fittings.

What is the difference of material WP5,WP9,WP11,WP22?

First of all,WP5,WP9,WP11,WP22 are steel grades from standard ASTM A234,,alloy pipe fittings of ASTM A234 WP1/ WP5 / WP9 / WP11,WP22 etc.(ASTM A234 WP5 Pipe Fitting)

ASTM A234,carbon steel material commonly used in WPB and WPC,alloy materials commonly used WP5/WP9/ WP11/WP12/WP22/WP91 etc.,these materials regardless of the chemical composition,mechanical properties and tensile properties are different.The specific values are as follows:
