Quality control measures for new weldless pipe technology
First of all, the staff should determine the materials used in the operation of petroleum machinery, number them according to their importance, and determine the technical procedures, set the welding size according to the requirements of the standard, and complete the corresponding assembly work. Secondly, there should be professional inspectors to manage the technical implementation procedures and ensure that each working procedure will not exceed the scope of the provisions. Finally, in the welding process, workers should master the temperature, clearly indicate each petroleum machinery pipeline, and evaluate it from the aspects of process mode and welding accuracy.
Welding repair quality control
Welding repair quality control is also very important in petroleum machinery construction. First, the staff should test the damaged parts and analyze the causes of the problems. Second, record the repair situation one by one to provide good conditions for the follow-up work. Third, usually, if a part has two problems, the staff can not repeat welding, to consider replacement parts. In addition, heat treatment should be carried out after the work is completed to achieve the purpose of fixing the internal structure.
