A403 WP316L Long Stub End Type A, Wrought Stainless Steel Fitting Connection To Lap Joint Flanges
An A403 WP316L lap joint stub end is a butt-weld pipe fitting manufactured in accordance with ASTM A403, made of WP316L austenitic stainless steel. Typically referring to a stub end, it is commonly used in conjunction with a lap joint flange to facilitate detachable connections in piping systems. This product is primarily manufactured to meet ASME B16.9 or MSS SP-43 standards and is available in long and short patterns depending on the length.
The forming process can involve cold or hot working. Due to the presence of molybdenum in its material composition, the WP316L lap joint stub end offers excellent corrosion resistance, particularly against chloride pitting, making it suitable for corrosive media environments such as those found in the chemical, petroleum, and pharmaceutical industries. Additionally, its low carbon content ensures good weldability, contributing to a long service life.
