Pipe welding heat treatment electric heater
Pipe heat treatment is a heat treatment method developed based on international advanced technical solutions. It is widely used in national-level electric power, petrochemical, metallurgical machinery engineering, and large and medium-sized boiler pressure vessels, shipbuilding, metal structures and other industries, for preheating before welding, intermediate hydrogen removal after welding, and annealing heat treatment during welding construction of pipes and pressure vessels. It has excellent performance such as fast heating speed, high heat utilization rate, significant energy saving, low labor intensity, safe and reliable use, and easy operation. It is a novel and practical local heat treatment heater in the current welding industry. Ceramic heaters are internationally known as flexible heaters. They are made of high-quality nickel-chromium alloy wire cables, covered with high-purity alumina ceramic insulation parts to form crawler-type or rope-type heaters and other product forms. It can be made according to the shape and size of the workpiece, and can be connected, bent, and wrapped tightly to heat the workpiece.
