Cutting: In the processing of alloy steel pipe, the commonly used cutting methods are flame cutting, plasma cutting, laser cutting, water cutting and so on. Select the appropriate cutting method according to the actual needs to ensure that the incision is smooth and without burrs.
Drilling: The drilling process of alloy steel pipe can be completed by ordinary drilling machines, turning centers and other equipment. Select the right drill bits, such as carbide bits, tungsten steel bits, high-speed steel bits, etc., to ensure the quality and efficiency of drilling.
Bending: Due to the high hardness of alloy steel pipe, the bending process requires the use of professional equipment and technology, such as sandbag method, mechanical rolling bending, pressure ball method, hot bending method, etc. When operating, pay attention to controlling the bending Angle and bending radius to avoid cracks or deformation.
Welding: Welding of alloy steel pipe can be done by manual arc welding, TIG welding, MIG welding and other ways. When selecting the welding method, it is necessary to consider the material characteristics, welding process requirements and equipment conditions. Before welding, the steel pipe should be pre-treated, such as polishing and cleaning, to ensure the welding quality. After the welding is completed, it is also necessary to conduct flaw detection on the weld to ensure that there are no defects.
