When installing the stainless steel elbow, pay attention to air tightness to prevent leakage and not affect the normal operation of the pipeline. When using stainless steel elbow ball valves, glove valves and gate valves, they can only be fully opened or fully closed. It cannot be used for flow control to prevent corrosion of the sealing surface and accelerated wear. The gate valve and the top screw stop valve are equipped with reverse seals, and the handwheel is turned upwards and tightened to prevent the medium from leaking from the packing.

According to the different processing temperature of the elbow, it is divided into two types: cold processing and hot processing. The main processing methods of stainless steel elbow are: semi-continuous rolling mill: including 1-stand Steckel rolling mill and 5-stand finishing rolling mill. In the semi-continuous rolling mill, the hot rolling experienced by the pipe in the finishing pass is essentially constant from one end to the other end of the pipe. The time between passes on the finishing mill is usually less than 3s. The process characteristic of the pipe fittings is the presence of central segregation in the continuous casting of thin slabs.

The material of stainless steel elbow is stainless steel, alloy steel and other materials. Stainless steel elbow is cheap and used in large quantities. Alloy steel elbows are used in special locations. The main difference between stainless steel elbow and carbon steel elbow is the material. The chemical composition of stainless steel elbow can prevent rust on the surface of the elbow for a long time, and it is not easy to be corroded. Stainless steel elbow has good corrosion resistance and oxidation resistance, and is widely used in chemical, fertilizer, petroleum, and medical machinery manufacturing.
