Forged Couplings Manufacturer

At Steel Icon Stainless Pvt. Ltd., we are a leading manufacturer and global supplier of forged couplings, engineered to provide strong, leak-proof pipe connections in high-pressure systems. Our couplings are made using high-quality stainless steel and duplex alloys, designed to withstand high pressure, temperature, and corrosive environments.

We manufacture a full range of couplings as per ASTM, ASME, MSS, and DIN standards, widely used in oil & gas, chemical processing, power generation, marine, and utility systems.

What are Forged Couplings?

Forged couplings are short, cylindrical pipe fittings used to connect two pieces of pipe in a straight line. They are forged from solid steel blocks and machined to tight tolerances, ensuring durability and high-pressure integrity.

Available in full, half, and reducing types, forged couplings are offered in both socket weld and threaded ends to meet diverse industrial piping needs.

Frequently Asked Questions

Explore our FAQs for insights on materials, customization, and delivery.

What is the purpose of a forged coupling?

To join two sections of pipe in-line, maintaining strength and pressure integrity.

Are reducing couplings available?

Yes, we supply standard and custom reducing couplings.

Which is better: socket weld or threaded?

Socket weld is ideal for permanent, high-pressure systems; threaded is best for quick installation and maintenance.

Can you supply custom sizes or alloys?

Yes, we offer custom sizing, threading, and materials based on your project needs.
