OEM Threaded Pipe Couplings Manufacturer - Sch40/Sch80 Heavy Series Water Pipe Fittings

Our premium half steel couplings are manufactured according to strict ASTM A865 and BS EN 10241 standards, ensuring reliable performance in various piping systems. These forged carbon steel fittings feature precision threads (NPT/BSPT) and are available in multiple surface finishes including black and galvanized options.

The product line includes both half merchant couplings for tank welding applications and full merchant couplings for heavy-duty pipe connections. Half merchant types feature a squared-off end for secure welding to metal tanks, while full merchant versions provide superior strength for vertical pipe applications.

All couplings undergo rigorous quality control processes to meet international standards including DIN, BS, ISO, ANSI, API and JIS. The manufacturing process includes precision forging, threading, and surface treatment to ensure durability and corrosion resistance.

These pipe couplings are widely used in fire protection systems, water distribution networks, HVAC installations, and industrial plumbing applications. Their robust construction makes them suitable for demanding environments where reliable pipe connections are essential.

The product is available in multiple series (Heavy, Standard, Medium, Light) to accommodate different pressure requirements and application needs. Custom specifications including special threading, lengths, and surface treatments can be accommodated for bulk orders.
