The YINGYEE Three-Shaft Steel Pipe Thread Rolling Machine is a high-precision industrial solution designed for the professional manufacture of cylinder and conic tube threads. Utilizing advanced cold-rolling technology, this machine employs internal and external roller brush wheels to deform pipe walls under preset spring pressure, creating high-strength threads through a combination of friction-induced heat and controlled rebound fatigue. This process ensures a seamless transition and superior structural integrity compared to traditional cutting methods.
Specifically engineered for high-pressure environments, our thread rolling technology eliminates the risk of stress corrosion often found in stainless steel. By avoiding the grooves created by cutting, the resulting connections are as rigid as the tube body itself. This makes it the ideal choice for critical applications, including fire control high-pressure water mist extinguishing systems with operational pressures reaching up to 16MPa, ensuring maximum safety and leak-proof performance.
