Elbow making mandrel head materials are generally, K18, 2520, 45#,ZG1Cr18Ni9Ti, ZG3Cr20Ni14
ZG1Cr25Ni20Si2, ZG0Cr20Ni25 and other stainless steel, alloy steel. The high temperature strength and wear resistance gradually increase, and the price also increases accordingly. If it is small batch production, you can choose
ZG1Cr18Ni9Ti, ZG3Cr20Ni14; if it is a mass production push elbow,
ZG3Cr25Ni20Si2, ZG0Cr20Ni25 should be selected, but the price of ZG0Cr20Ni25 is too high, and it is generally used in the process of making small outer diameter elbows.
The material of the mandrel head is ZG1Cr25Ni20Si2. Pushing elbow mandrel heads are divided into three types: single curvature, double curvature and multi-curvature according to the radius of curvature. For single-curvature, double-curvature, and multi-curvature mandrels, the thrust is gradually reduced, and the production cost is gradually increased. The double-curvature mandrel was selected for this test. According to the shape of the section, it is divided into two types: circular section and elliptical section. The circular section is simple to make and the cost is low, but the ovality and thinning rate of the elbow are too large; the elliptical section is complicated to make and the cost is high, but the same as the butt welding elbow The difference is that the ovality and thinning rate of the push elbow are small. This time, the elliptical section mandrel is selected. According to whether there is a shaping segment, it is divided into two types:
mandrel head with shaping segment and mandrel head without shaping segment. Mandrels with shaping segments are complicated to manufacture, high in cost and long in use; mandrels without shaping segments are simple to manufacture and low in cost. Our company has professionals to debug the finished elbow. Our products are highly trusted and praised by foreign customers, who have become our partners many times.
