Study on High-Frequency Quenching of Steel Tube Screw Thread Lined Glass Used for Petroleum Pipe Line

Abstract:

The easy-to-wear and easy-to-deform of screw threads resulting in screw thread damage often form to the steel tube lined glass used for petroleum pipe because of their low joining strength. The reason resulting above problem was found through experiments. Moreover, it was found that the high-frequency quenching and tempering heat treatment process could effectively improve strength of screw threads with optimized process parameters. The optimized parameters are output power, frequency, and thickness of steel tube wall, high degree of screw threads, induction coil current, relative speed, and medium jet pressure, respectively. The high-frequency quenching and tempering heat treatment processes are a new approach to improve the hardening of strength for the steel tube lined glass.
