For applications involving special shapes like pipes and pipe fittings, as well as areas around heating elements where space is limited and difficult to work in, rope heaters are particularly suitable.

Ceramic electric heaters developed based on technical scheme research and development. Widely used in the pre-heating before welding, intermediate dehydrogenation after welding, and heat treatment after quenching of alloy steel structural components, pipes, and pressure vessels for boiler, chemical, shipbuilding, power construction, and mechanical departments. They possess excellent properties such as fast heating speed, high thermal utilization, significant energy saving, low labor intensity, safe and reliable operation, and easy handling. They are a practical local heat treatment heater in the current welding industry. Ceramic heaters are commonly known as flexible heaters internationally, and they are made from high-quality nickel-chromium alloy wire cables and high-purity alumina ceramic insulating materials into belt or rope-type heaters, as well as other product forms. They can be customized according to the shape and size of the workpiece, and can be connected, bent, and wound tightly to heat the workpiece.
