Butt-Weld Cap Fittings
Butt-Weld Caps are high-strength piping components designed to seal the end of a pipe securely. These fittings are used to terminate piping systems, isolate sections of pipelines, or provide future expansion capability. Manufactured using advanced hot-forming and butt-weld preparation processes, butt-weld caps offer excellent mechanical strength, dimensional accuracy, and long service life in high-pressure and high-temperature applications.
