ASTM A403 / ASME SA403 / EN10253-4 WP304L 1.4307 CAP STAINLESS STEEL BUTT WELD FITTING
概述：
WP304L is a type of stainless steel material used in piping fittings. A cap is a type of fitting that is used to cover the end of a pipe.
A WP304L cap is a pipe fitting made from WP304L stainless steel material. It is designed to fit over the end of a pipe and provide a seal， preventing fluid or gas from escaping. WP304L is a low-carbon variant of the popular 304 stainless steel. This material is often used in applications that require corrosion resistance， such as in the chemical， petrochemical， and food processing industries.
The WP304L cap is designed to be welded onto the end of a pipe. It is available in various sizes and shapes to fit different pipe diameters and end configurations. The cap is usually fitted with a socket weld， butt weld， or threaded connection， depending on the application requirements.
