Description
Pipe Couplings & Unions join two lengths of pipe with a strong, leak-free connection. In particular, we supply heavy-wall forged couplings and unions for high-pressure, high-vibration and high-temperature lines. Fitting World Trading LLC keeps ASME B16.11 and BS 3799 stock at our showroom in Nad Al Hamar, Dubai. As a result, plants, contractors and marine yards across the UAE and GCC can collect the same day.
We forge our pipe couplings and unions from ASTM A105 carbon steel and ASTM A182 F316L / F304L stainless steel. First, you can choose threaded ends (NPT to ANSI B1.20.1 or BSPT to BS 21) or socket weld ends. In addition, both styles come in 3000# and 6000# pressure classes. For high-pressure work, we also stock Bothwell high-pressure forged fittings.
Why Choose Our Pipe Couplings & Unions
- High pressure rating: Because the body is heavy and forged, it holds surge pressure up to Class 3000 (3,000 PSI) and Class 6000 (6,000 PSI).
- Clean CNC threads: We cut tapered NPT and BSPT threads with sharp crests and roots. Therefore, each joint engages tightly and holds sealant well.
- Deep socket weld pockets: Accurate bores keep the pipe aligned. At the same time, they leave the correct expansion gap before fillet welding.
- Solid forging: Die forging removes porosity, sand and casting voids. Because of this, the fittings are safe for gas and hydraulic service.

Where Pipe Couplings & Unions Are Used
- Hydraulic and lube oil lines: for example, heavy equipment piping, compressor discharge lines and hydraulic power units.
- Chemical and sampling systems: for instance, instrument take-offs, impulse piping and chemical injection manifolds.
- Steam and boiler piping: such as steam traps, boiler blowdown lines and condensate drain headers.
- Fire protection: in particular, high-pressure sprinkler mains and deluge valve trim.
