When installing stainless steel elbows, pay attention to the airtightness to prevent leakage and avoid affecting 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 accelerate wear. The gate valve and the top screw stop valve are equipped with reverse seals. Turn the handwheel upwards and tighten it to prevent the medium from leaking from the packing. 

　　According to the different processing temperatures of elbows, they are divided into cold working and hot working. The main processing methods for carbon steel elbows include: semi-continuous rolling mills: including1Rack furnace coil rolling mill and5Rack finishing rolling mill. On a semi-continuous rolling mill, the hot rolling that a pipe fitting undergoes in the finishing pass is essentially constant from one end of the fitting to the other. The time between passes on the finishing mill is usually less than3s.The technological characteristic of the pipe fitting is that there is central segregation in the continuous casting thin slab.

　　The materials of elbows are carbon steel, stainless steel, alloy steel and other materials. Carbon steel pressed elbows are inexpensive and widely used. Alloy steel elbows are used in special positions. The main difference between stainless steel pressed elbows and carbon steel elbows lies in the materials. The chemical composition of stainless steel elbows can prevent rusting on the surface of the elbows for a long time and is not easily corroded. Stainless steel elbows have excellent corrosion resistance and oxidation resistance, and are widely used in the manufacturing of chemical engineering, fertilizers, petroleum, and medical machinery.
