Hydraulic Used Pipe Bending Machine for Large-Diameter Elbow Production
The Hydraulic Used Pipe Bending Machine is a specialized heavy-duty equipment engineered to produce large-diameter pipe elbows, catering to pipe fitting manufacturing in industries like oil & gas, petrochemicals, power engineering, and municipal infrastructure. It leverages hydraulic drive technology for stable, high-torque bending, enabling it to handle thick-walled, large-diameter pipes that standard pipe benders cannot process.
This machine offers an optimal balance of processing capacity and bending precision, covering pipe diameters from 325mm to 1066mm and wall thicknesses of 10-50mm. It maintains strict quality control with pipe wall thinning rate (<10%) and elbow ellipticity (<10%), ensuring bent elbows meet industry standards for structural strength and pressure resistance.
