Spiral welded steel pipe

Hot expansion steel pipe mandrel surface pulsating spray device is a device to a thermal expansion pipe mandrel surface spray lubricant, which is characterized by injection device body ring parts with lubricant reservoir burglary, in Chu burglary ring wall open lubricationagents enter the hole, motor Chu burglary side installation, its spindle by driving wheel and the middle with a lubricant output hole pulsating ring phase, the lower part of the output hole placement beam radio regulatory group equipped with a beam of radio regulation.

Advantages are:using spray lubricant to the mandrel surface, can reduce the frictional resistance between the tube rolling mandrel and steel pipe to reduce the pressure load of the mill and the mill's power consumption to extend the life of the mandrel, to improve the quality of the steel pipe rolling.

Hot expansion pipe with two-step push tube expanding machine set conical die expanding technology, digital intermediate frequency induction heating technology, hydraulic technology in a machine with a reasonable process, low energy consumption, lower capital investment, good product quality, a wide range of applicability of the raw material and product specifications, flexible variable cost of production volume, adaptability, replace the traditional steel industry, of Pullout expanding technology. difficult to resolve in the near future, the supply of large diameter steel pipe, thermal expansion pipe to become the source of the shortage of large-diameter steel pipe products. ease the tight supply situation of the large diameter pipe market.
