Pipe heat treatment is a heat treatment method developed based on international advanced technology 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 tempering heat treatment of pipes and pressure vessels. It has the excellent performance of fast heating speed, high heat utilization rate, significant energy saving, low labor intensity, safe and reliable use, and convenient operation. It is a novel and practical local heat treatment heater in the current welding industry. Ceramic heater is internationally known as flexible heater. It is made of high-quality nickel-chromium alloy wire cable, covered with high-purity alumina ceramic insulation parts to form a crawler
type or rope type heater and other product forms. It can be made according to the shape and size of the workpiece, and can be connected in parallel, bent, wound and tightly attached to the workpiece for heating.
