Self Aligning Rotator , Pipe Welding Rollers PU 20 Ton 1.5Kw Inverter Motor Self Aligning Rotator , Pipe Welding Rollers PU 20 Ton 1.5Kw Inverter Motor Pressure vessels are basic containers that hold gasses and liquids at different pressures. They are frequently used in industries and private sectors globally for pressure reactors, autoclaves, compression chambers, water storage, compressed air and much more. However, because they are dangerous in nature, their construction, development, and engineering are dictated by several parameters which determine the maximum operating temperature and pressure. Our welding rotator provide a safe and reliable service for welding pressure vessels. Product Details The Welding Rotators are built in capacities 20ton. The wheels are wrapped by thick PU, which can ensure the support capacity and last working long time. The specifications are as follow1. Each set includes 01 powered unit and 01 or more idler units with electrical control system.2. Both power unit and idler unit fit the tank automatically, no adjustment need for different diameters.3.
