Pipe Bender
The SUNTECHMACH STW‑4J is a professional-grade solution for precision bending of steel pipes up to 4″, built for demanding industrial tasks like plumbing, maintenance, and heavy construction. Powered by a 23-ton hydraulic system, it delivers high force with clean bending results even on thick-walled pipes without deformation or flattening. Its reinforced steel frame and complete bending die set ensure long-term durability, high flexibility, and reliability across varied job sites and pipe diameters.
