Abstract: Petroleum drill rod joint is an important part of the petroleum drilling tools while oil pipeline coupling is an essential part used to connect the petroleum drilling tools.This paper introduces the technological process that uses the impact molding to produce the oil pipeline coupling and describes the selection of blank raw materials,design of blank drawings and tooling drawings,calculation of extrusion pressure and production process.After final physical and chemical analysis and test,the performance index completely meets the regulations of American Petroleum Institute Standard APISPEC5CT and it is a process method that can reduce production cost and improve product performance.
