Product Description
The Butt Weld End Cap is a pipe fitting designed to close or seal the end of a piping system, ensuring complete termination of flow and maintaining pressure integrity. Manufactured in accordance with ASME B16.9, this fitting is widely used in industries where reliable pipe closure is essential.
Our Stainless Steel Butt Weld End Caps are available in SS 304 / 304L / 316 / 316L, and come in both seamless and welded types. They are ideal for use in oil & gas, chemical processing, power generation, water treatment, and food-grade applications.
The smooth internal and external finish of the end cap ensures easy welding and minimizes flow turbulence. Available in a variety of sizes and wall thicknesses (e.g., SCH10 / SCH40 / SCH80), our pipe caps meet global standards and project specifications.
