Hdpe Pipe Calibration Unit

The HDPE Pipe Calibration Unit, often a Vacuum Sizing Tank, is a crucial component in High-Density Polyethylene pipe extrusion lines, designed to ensure the final product has a precise outer diameter and roundness. Typically constructed from durable materials like stainless or mild steel, it uses vacuum pressure and a copper calibration sleeve to force the hot, newly extruded pipe against the sleeve's inner wall. Simultaneously, a water spray cooling system efficiently solidifies the pipe's shape, ensuring consistent dimensions and high-quality surface finish. Specifications vary, accommodating pipe diameters from small to over 2600 mm, and featuring components like vacuum pumps, water pumps, and frequency speed controls for automatic operation.
