Forged Caps Manufacturer
At Steel Icon Stainless Pvt. Ltd., we are a renowned manufacturer and exporter of forged caps, designed to securely seal the ends of piping systems. Built to endure high pressure, temperature, and corrosion, our forged caps are ideal for both permanent and temporary pipe closures in industries such as oil & gas, chemicals, power, marine, and infrastructure.
Made from premium stainless steel and duplex alloys, our forged caps meet international standards like ASTM, ASME, MSS, and DIN, ensuring precise dimensions and leak-proof performance.
What are Forged Caps?
Forged caps are pipe fittings used to seal the open end of a pipe, effectively preventing fluid or gas from escaping. They are typically installed using socket weld or threaded connections, providing a secure and maintenance-free seal.
These caps are particularly valuable in systems that require pressure testing, shutoff, or protection, offering a dependable solution for high-pressure and corrosive environments.
