Forged Caps Manufacturer
At Steel Icon Stainless Pvt. Ltd., we are a prominent manufacturer and exporter of forged caps, engineered for securely sealing the ends of piping systems. Designed to withstand high pressure, temperature, and corrosion, our forged caps are ideal for permanent or temporary pipe closures across industries such as oil & gas, chemical, power, marine, and infrastructure.
Manufactured from high-grade stainless steel and duplex alloys, our caps comply with international standards like ASTM, ASME, MSS, and DIN for dimensional precision and leak-proof performance.
What are Forged Caps?
Forged caps are pipe fittings used to close the open end of a pipe, preventing fluid or gas from escaping. These are typically installed via socket weld or threaded connections, offering a secure and maintenance-free seal.
Forged caps are especially useful in systems that require pressure testing, shutoff, or system protection, and are a reliable solution for high-pressure and corrosive environments.
