Wide Range of Forged Caps as per ASME B16.11 – Socket Weld and Threaded End Connections – Offered in A105 Carbon Steel, F304/F316L Stainless Steel, F11/F22 Alloy Steel, Duplex 2205, and Nickel-Based Alloys including Hastelloy C276, Inconel 625 & Monel 400.
Forged caps are essential piping components used to seal the end of a pipe, preventing flow and protecting the system from contaminants. Manufactured through a forging process, these caps offer superior strength and durability compared to cast or fabricated alternatives. They provide a secure, leak-proof closure that can withstand high pressure, temperature variations, and corrosive environments, making them ideal for critical piping systems.
Forged caps are available in various sizes, typically ranging from 1/8” to 4”, and are designed to meet industry standards such as ASME B16.11. They come in different materials including Carbon Steel (ASTM A105, A350 LF2), Stainless Steel (ASTM A182 F304, F316, F321, etc.), Alloy Steel (F11, F22, F91), Duplex and Super Duplex Steel, and Nickel Alloys such as Inconel and Monel. The forging and heat treatment processes enhance their mechanical properties, ensuring excellent dimensional accuracy, impact resistance, and corrosion protection.
These caps are widely used in industries such as oil and gas, petrochemical, power generation, chemical processing, and marine engineering. They are particularly useful for temporarily or permanently capping pipelines during maintenance, system modifications, or shutdowns. Forged caps provide reliable sealing solutions that help maintain system integrity, prevent leaks, and ensure safe operation in demanding industrial environments.
Precision Forged End Cap – Conforming to ASME B16.11 Standards – Available in Socket Weld and Threaded Ends – Sizes 1/8”–4”, Pressure Classes 2000/3000/6000/9000 – Designed for secure sealing of pipe ends in high-pressure systems.
