Automatic Pipe Fitting Tightening Machine | Threaded Pipe Fitting Assembly Equipment | DN15-DN65 Tee, Coupling & Elbow

The 4KW Automatic Pipe Fitting Tightening Machine is designed for efficient and consistent assembly of threaded pipe fittings in pipe prefabrication production. It is widely used in fire protection piping, HVAC systems, building MEP projects and other industrial pipeline applications.
Equipped with a 4KW drive system and maximum 400N.m tightening torque, the machine provides stable tightening force for DN15-DN65 threaded fittings, including couplings, elbows and tees. Compared with manual tightening methods, it improves assembly consistency, reduces labor intensity and increases production efficiency.
The machine adopts automatic clamping, positioning and constant torque control technology to ensure repeatable tightening results during batch production. It helps reduce problems caused by inconsistent manual operation, such as uneven tightening force and unstable assembly quality.
With a compact structure of 1200mm × 800mm × 900mm and standard 380V / 50Hz industrial power supply, the equipment is easy to install and suitable for integration into pipe prefabrication workshops and production lines.
