Pipe caps are butt weld fittings designed to close and seal the ends of piping systems, preventing fluid leakage and protecting pipelines from external contamination. They are commonly used for permanent pipe termination, pressure containment, pipeline testing, and future pipeline expansion requirements.
Manufactured according to ASME B16.9 standards, butt weld pipe caps are available in carbon steel, stainless steel, and alloy steel materials. With excellent strength, accurate dimensions, and reliable welding performance, they are widely applied in oil & gas pipelines, chemical plants, petrochemical systems, power generation facilities, pressure piping, and industrial process systems.
