Zero-radius bends process: in the manufacture of air-conditioning equipment, hot water heat exchanger device, such as when a large variety of materials · elbow wall thickness, due to piping space, hoping elbow bend radius as small as possible. In recent years, large elbow preferred Hebei billion gold, the use of a combination of bending and hydraulic methods successfully developed a bend radius of zero bending processing technology. As shown, the upper and lower mold molding composition, the steel pipe is inserted in the upper and lower mold, the inner pressure applied to P, the relative movement of upper and lower dies under the effect of the thrust of the tube W, so that the bending radius of the pipe to produce zero. To prevent the bending deformation partially broken, the force F is applied to both ends of the tubes. Choose suitable internal pressure P, the pressure and mold-moving force F W, helps to reduce the possibility of bending pipe defects generated in the process to obtain high-quality molded elbow. All along, the major construction projects in the pipe industry, bends are assumed its most important role. Bending role can not be ignored. Meanwhile, in other areas of national construction, pipe also assume a crucial role. Bend in the petrochemical, coal chemical, electric power industry, metallurgical industry, oil gas and other fields have important applications, and demand was growing rapidly. Our tube bending industry to maintain rapid growth of large manufacturers, expanding industry, continued strong demand for pipe products of large pipe, apply its advanced equipment and technology is an important driving force. Therefore, China should continue to increase investment in technology to elbow, elbow and timely technical innovation and technology to make the elbow does not become a bottleneck in the development of various industries. And to meet domestic demand, based on efforts to open international markets to become the world's leading exporter of bending and bending technology.
