Division and precautions of stainless steel elbow
Feb. 02, 2021
The chemical composition of the stainless steel elbow can prevent rust and corrosion on the surface of the elbow for a long time. In the pipeline system, the elbow is a pipe fitting that changes the direction of the pipe. The three most commonly used are 45° and 90°180°. According to engineering needs, other abnormal corners such as 60° are also included.
Elbows are made of cast iron, malleable cast iron, carbon steel, non-ferrous metals, stainless steel, alloy steel and plastics; pipe connection methods include: electrofusion connection, direct welding (the most common method) flange connection, threaded connection, heat Melt connection, socket connection, etc.; according to the production process, it can be divided into welding elbow, casting elbow, stamping elbow, forging elbow, hot pressing elbow, push elbow, clamping elbow, etc. Other names: 90 °Elbow, right angle elbow, etc.
According to the standard production can be transformed into:
According to the manufacturing standards, stainless steel elbows can be divided into American standard, electric standard, German standard, ship standard, national standard, Japanese standard, water standard, Russian standard, etc.
According to the production method, stainless steel elbows can be divided into stamping, extrusion, forging, casting and so on.
The 90° stainless steel elbow is mainly used for the connection of pipe bending. It is used as one of the connection joints for pipe installation and connects two pipes with the same or different nominal diameters to rotate 90°.
The characteristics of stainless steel: its most prominent advantage is corrosion resistance. Stainless steel must be used in extremely corrosive occasions, such as the chemical industry and paper industry, and of course the cost is relatively high. Its strength and toughness indicators are the best among all steels.
Precautions for using stainless steel elbow
1. During installation, under normal circumstances, it can be installed at any position of the pipeline, but it needs to be sealed to prevent flushing leakage and affect the normal operation of the pipeline. The stainless steel elbow can be directly installed on the pipeline according to the connection method or use position.
2. When using ball valves, globe valves and gate valves with stainless steel elbows, they do not allow flow adjustments, so they can only be fully opened or closed.
3. Regular inspections should be made for the purpose of long-term preservation of stainless steel elbows. The elbow should be stored neatly in a ventilated and dry place indoors. The exposed surface should be kept clean, and any dirt should be removed in time. Stacking and open storage are strictly prohibited. Always keep the stainless steel elbow dry and ventilated, keep the elbow clean and tidy, and store it according to accurate storage methods.
