Grades of Alloy steel buttweld pipe fittings: What are they? ASTM grades of alloy steel buttweld pipe fittings include various classifications, such as A234 WPB, which denotes the material&#8217;s specific chemical and mechanical properties. These grades ensure that fittings can withstand high pressure and temperature applications, making them essential in industries like oil and gas, power generation, and construction. Key Highlights ASTM A234 Grade WPB is a standard specification for wrought carbon steel and alloy steel pipe fittings. These buttweld fittings are designed for moderate and high-temperature service in pressure piping systems. A steel elbow changes the direction of flow and is available in 45\u00b0 and 90\u00b0 angles.
