Thickened Copper Straight Coupling

The thickened copper straight coupling is made of T2 high-purity copper in one piece, and is the core accessory for copper pipe butt joint in air conditioning, water pipe and floor heating systems. The overall thickened design of the fitting has a wall thickness of 2.0-3.5mm (adapted according to pipe diameter), which is 40% thicker than ordinary straight couplings, and the pressure-bearing capacity is increased to 1.6-2.5MPa, suitable for medium and high-pressure pipeline systems. Both ends of the socket adopt precision flaring process, with inner diameter tolerance controlled within ±0.05mm, adapting to plug-in welding of Φ6-Φ80mm full-specification copper pipes, with full solder filling and excellent sealing performance, leakage rate ≤1×10⁻⁹Pa·m³/s. The inner wall is smooth without burrs, and the fluid resistance coefficient ≤0.3, ensuring smooth medium delivery. The surface undergoes anti-oxidation treatment, resistant to moisture, acid and alkali corrosion, and has stable perfor…
