Precautions for cutting and flanging of 304 stainless steel pipe2018-09-04 When cutting and beveling 304 stainless steel pipe, it is important to note that 304 stainless steel pipe cannot be used with oxygen-acetylene flame. Remember to open the bevel because of its greater toughness , High wear resistance and strong cutting adhesion, as well as the simple occurrence of main hardening and other characteristics. The method of cutting 304 stainless steel pipe should be determined according to the size of the pipe diameter. The pipe's nominal size DN<25mm, cut it with a hand-made hacksaw or saw; the pipe's nominal size DN>25mm, cut it with a grinding wheel, but the grinding wheel It should be dedicated, perhaps with a plasma cutting machine. Cool down in time when cutting 304 stainless steel pipe. The bevel processing method is determined by the welding standard. The bevel can be processed by craftsmanship, electric beveling machine or lathe. The coolant is used for smooth cooling during processing, which can extend the service life of the tool and reduce the surface roughness of the groove. The 304 stainless steel pipe mouth flanging should be formed by short pipe section stamping. The stamping die is made of stainless steel or medium carbon steel. The inner diameter of the outer die should be 1mm larger than the outer diameter of the steel pipe. The arc radius of the inner mouth should reach the flanging requirement. For rounded corners, the outer diameter should be equidistant, and there should be no defects such as wrinkles, cracks and scratches on the outside. When it is inconvenient to punch, you can use craftsmanship to flange. Put the flanged pipe section on the flange. The length of the 304 stainless steel pipe mouth extending from the flange surface should be equal to the width of the flanged shoulder ring. Use a 304 stainless steel pipe or a copper hammer to strike a 90°-bent shoulder from the inside of the pipe mouth. ring. During the flanging process, the force should be even and moderate, and no pits or pits should be hit on the flange surface. Welding rings can also be used under the conditions permitted by the plan.
