Some users of seamless stainless steel tubing need to bend it into a U-shape. If they do so according to standard practice, they must have specific mechanical tools to do so, otherwise it is unlikely that they will get good bending results. Before starting work, it is important to understand the basics of stainless steel seamless tubes. For example, it is necessary to understand the relationship between the dimensions of the seamless stainless steel tube and the loading method.
Assume that there are three cases: 1. the diameter of the round pipe is equal to the side length of the square pipe, and the wall thickness is the same; 2. both pipes are simply supported; 3. the loading pattern is a transverse concentration of force at the midpoint. The extreme moment of inertia of the round pipe is smaller, which will lead to large deflection of the round pipe and larger bending deformation of the round pipe. It is worth thinking how to deal with this situation. If a plain stainless steel seamless tube is bent without mechanical assistance, a similar soil method will be used: the stainless steel seamless tube is filled with sand and then bent.
Honestly, if the stainless steel seamless tube is very thin and without mechanical assistance, the probability of success is really small. Customers are advised to go to a stainless steel industrial seamless tube manufacturer for processing. Usually, stainless steel seamless tube manufacturers have these machines, or they can buy the finished product directly from the manufacturer. The price should be about the same. The standard mechanical collaboration stainless steel seamless tube bending method can be referred to the following practices: 1. If not required, both sides should be concave inward to avoid cracking of the stainless steel seamless tube; if the surface of the stainless steel seamless tube is required not to be concave, it can be ensured by the core plugging method; the raw material of the stainless steel seamless tube should be qualified; the inside of the stainless steel seamless tube is concave, which means there is a protrusion in the middle of the mold on the inside of the bending machine. When bending, a recess can be pressed on the inside of the stainless steel seamless tube.
