Industrial Pipe Couplings & Unions – Forged Steel, Malleable Iron & Stainless Steel

Pipe Couplings & Unions are essential piping connection fittings engineered to join pipe sections, facilitate equipment disconnection, or adapt line sizes with leak-tight mechanical reliability. K. Hashim LLC supplies full couplings, half couplings, reducing couplings, and spherical union assemblies from our Sharjah warehouse, serving marine shipyards, industrial workshops, and MEP contractors across the UAE since 1976.

Our coupling and union inventory includes ASME B16.11 forged steel fittings in 3000# and 6000# pressure classes, malleable iron unions with brass-to-iron ground joints, and precision stainless steel (SS316/SS304) threaded fittings. Available in female NPT (ANSI B1.20.1), BSPT (BS 21), and Socket Weld (SW) connection ends.

Key Engineering & Structural Features

• Rapid Equipment Disconnection: Unions feature precision-ground metallic spherical seats (bronze-to-iron or SS-to-SS) allowing zero-clearance component maintenance.
• High-Pressure Containment: Forged ASTM A105 and SS316 bodies contain working pressures up to 3000 PSI and 6000 PSI without joint distortion.
• Precision Thread Quality: Gauged taper threads guarantee deep engagement, optimal thread engagement length, and positive sealant retention.
• Full Traceability & Certification: 100% material test certification provided with full heat number markings per EN 10204 Type 3.1.

Technical Specifications & Standards

Applications Across UAE & GCC Projects
