ASME SA403 WP304 Cap is a high-quality stainless steel pipe fitting, strictly manufactured in accordance with ASME SA403 (equivalent to ASTM A403) and ASME B16.9 standards.It is made of WP304 austenitic stainless steel (UNS S30400), featuring excellent corrosion resistance, good weldability, stable mechanical properties and strong adaptability. As a key end-sealing component for industrial pipelines, it is specially designed to seal the end of pipelines, prevent medium leakage, protect the internal structure of pipelines from external pollution, and play a role in pressure-bearing and isolation. It is suitable for low to medium pressure, normal temperature and mild corrosive working conditions, widely applied in various industrial and civil pipeline systems, serving as a reliable end-sealing fitting for pipelines conveying water, gas, oil, chemical reagents and other media.
