Welded pipe caps are a type of piping component used to seal the end of a pipe, effectively closing it off. They are commonly used in piping systems to terminate pipelines or to provide protection against contamination, debris, or corrosion, and weldable pipe caps (a general term for weld-compatible sealing fittings) share these core functions for diverse industrial needs. Welded pipe caps are attached to the pipe by welding, ensuring a strong, leak-proof connection, with the butt weld end cap being a specialized variant favored for its seamless integration in high-pressure pipeline configurations.
Hemispherical Caps: Provide a rounded, dome-like shape, offering uniform stress distribution and high pressure resistance.
Conical Caps: Have a tapered design, often used in applications requiring gradual flow transition or drainage.
Flat Caps: Feature a flat end and are used in low-pressure applications or where space is limited.
Leak-Proof: Welding ensures a secure and leak-free connection.
Durability: Made from high-quality materials, they can withstand harsh environments.
Versatility: Available in various sizes, materials, and pressure ratings to suit different applications.
