diameter expanderIt is a mechanical equipment for eliminating the forming pressure and welding stress of steel pipe in the production process of large diameter straight seam welded pipe,diameter expanderIs the production of oil, natural gas, gas and other special pipe necessary key equipment. In the steel pipe production process, will be in the appearance of bending, deformation, micro stress, strain; welding process of local heating also produce stress concentration, so the quality of the steel pipe will be greatly affected, the usediameter expanderNot only can effectively eliminate the steel pipe forming pressure and welding stress, but also played a role in straightening and shaping the steel pipe, so that its straightness, roundness, diameter, etc. are more ideal, while enhancing the radial bearing capacity of the steel pipe. Eliminating the forming pressure and welding stress of steel pipe by mechanical expansion not only reflects the level of welding production technology of pipe manufacturing enterprises, but also directly affects the production quality and economic benefits of steel pipe. At present, domestic and foreign similardiameter expanderthere are some unreasonable points,diameter expanderSet on the trolley, there is no wear-resistant friction gasket between the expansion block and the expansion head, relying solely on lubricating oil, etc., which brings a lot of inconvenience to the actual production.

 

diameter expanderIt is to provide a fully automated use of mechanical expansion to eliminate the forming pressure and welding stress of steel pipes, and to shape and improve the bearing capacity of steel pipes.diameter expander.

 

diameter expanderIt has the advantages of high power, high speed, single rod and expanding diameter to the end. Due to the use of T-shaped slider guide and lining with wear-resistant pad between the twelve square cone core and the expansion block, the wear resistance of the diameter expander is improved anddiameter expanderThe service life.diameter expanderA feeding device (friction wheel driven by chain) is also installed on the support of the diameter expanding machine, so that the diameter expanding can continue to the end and the whole pipe can be tempered. A steel pipe straightening machine is attached to support the steel pipe after diameter expansion, and at the same time, it is of great help to prevent the steel pipe from buckling and deforming and adjusting the internal quality.diameter expanderCompared with similar domestic models, the efficiency is high, the power is 5 times larger, and the processing speed is also increased by 5 times.
