Let You Know The Production Process Of Stainless Steel Elbow

Let me show you the production process of Stainless Steel Weld Elbow:

1. Stainless steel stamping elbow is the weak link in the pipe system. The performance of the pipe is mainly determined by the working capacity of the stainless steel stamping elbow.

2. The process parameters that affect the geometric shape of the stainless steel stamping elbow are: the material, wall thickness and outer diameter of the blank for pushing, the material and shape of the mandrel head, the heating temperature and its distribution, and the pushing speed.

3. The working capacity of the stainless steel stamping elbow is related to the stress state it is in. Calculation and on-site measurement of the working stress of the pipe fittings found that the arc starting point of the stainless steel stamping elbow is particularly sensitive to external loads. In addition to the external loads such as internal pressure and deadweight, the main external loads are the additional external loads caused by the thermal expansion of the pipe metal during the startup process of the pipe system, the vibration of the pipe system, and the abnormal operation of the support and hanger.

4. When the arc-starting section of the stainless steel stamping elbow is a butt weld, these changing external loads will cause the weld to be in a complex stress state, seriously weaken the weld strength, reduce the working capacity of the stainless steel stamping elbow, and shorten the service life of the stainless steel stamping elbow. For this reason, from a design perspective, the interface of the stainless steel stamping elbow is changed to a straight section butt, that is, the design of a stainless steel stamping elbow with a straight section is conducive to the butt welding of the weld, improves the quality of the weld, and improves the service life of the stainless steel stamping elbow.

5. Different factors have different effects on stainless steel stamping elbows. They need to be used in accordance with the corresponding ways and methods in use to determine the specific use value and function of stainless steel stamping elbows in use.

6. The principle for determining the heating temperature of stainless steel stamping elbows is that the material is above the austenitizing temperature, and the main compressive stress of the inner wall of the elbow is less than the limit of the material at this temperature during pushing.
