Sand Blasting Welded Stainless Steel Pipe End Cap for Chemical Line Applications

Our industrial-grade stainless steel pipe cap is designed to close the end of a pipeline securely, preventing flow and protecting pipe integrity during maintenance, testing, or long-term shutdown. Made from premium 304 or 316L stainless steel, this cap offers excellent corrosion resistance, high pressure tolerance, and long service life in demanding industrial environments.

Product Types:

We offer a variety of pipe caps to meet different piping requirements:
 • Convex Cap: Includes elliptical, dished, and hemispherical shapes; ideal for pressure systems.
 • Flat End Cap: Cost-effective solution for low-pressure or non-pressurized systems.
 • Conical Cap: Used in special-purpose equipment or directional closures.
 • Sanitary Clamp Cap: Designed for quick installation/removal in food and pharmaceutical pipelines.

Connection Types:

 • Butt Weld Cap (standard for pressure pipelines)
 • Socket Weld Cap (for small bore and high-pressure systems)
 • Threaded Cap (easy to install and remove for maintenance)
 • Clamp-on Cap (used in sanitary applications with tri-clamp connections)
