Development and Design and Heat Treatment of Production, Storage and Mine Drilling Pipes in Petroleum and Geothermal Industries

In this study, sequential and different temperature heat treatments were applied to steels after austenating heat treatment applied to different AISI steel types. The effects of tempering heat treatment applied on the mechanical properties of the steel after quenching were investigated. The production of prototypes of the materials to be used in the drilling industry and the improvement of the properties of the drilling pipes used in the geothermal, petroleum, storage and mining sectors by thermal processes determined according to the standards have been realized. Different heat treatments have been applied to the materials in AISI standards provided by considering the desired material properties of the drill pipes. In order to improve the mechanical properties, the heat treatment process was determined and applied by a wide literature review. The prototypes of the drill rods were produced in three different AISI standards (AISI 4130, AISI 4140). Seamless tubes are produced according to AISI 4340 and ductile, semi-ductile and brittle conditions. 946.4 MPa. In addition, corrosion tests showed significant corrosion resistance
