Significance of the heat treatment process of oil casing

 　　In addition to the emergence of oil casing, it can also be used as a pipeline for transporting raw materials. To enhance the quality of oil casing, every link in the production process is particularly important. In particular, the temperature control during the period must be strictly followed. Regulations are mastered. Under normal circumstances, oil casing uses the sub-temperature quenching method.

　　Many friends will wonder why it is not an ordinary quenching method? Because the common quenching method will cause a large amount of residual stress inside the workpiece, which enlarges the brittleness, the subsequent processing is not so convenient. The sub-temperature quenching is to prevent the excessive brittleness of the oil casing from affecting the subsequent process. Each kind of steel has its heating temperature and time during heat treatment. As long as the performance of the workpiece can be improved and improved, the purpose of heat treatment will be achieved.

　　Heat treatment is the most important process in the processing of petroleum casing. Whether the performance and quality of the finished product can meet the standard depends mostly on the result of heat treatment. Therefore, Xinyue has very strict requirements on the heat treatment process, and dare not be negligent. Sometimes it can also be quenched by low-temperature quenching.

　　Low-temperature quenching can effectively remove the residual stress of the oil casing, not only reduces the degree of deformation of the workpiece after quenching but also can process the oil casing into a more suitable raw material for the later process. Therefore, the current achievements of oil casing are inseparable from heat treatment. The impact toughness, damage resistance, and tensile strength of oil casing have been greatly improved.
