In piping systems, elbows are pipe fittings used to change the direction of pipes. From an Angle perspective, the most commonly used elbow is45°,90°and180°. In addition, according to the engineering requirements, it also includes60°For other Angle elbows, stainless steel elbows are mainly different from carbon steel elbows in material. Their chemical composition will prevent the surface of the elbows from rusting and corroding for a long time.
According to the production process, they can be classified into welded elbows, pressed elbows, hot-pressed elbows, pushed elbows, cast elbows, forged elbows, clamped elbows, etc. Elbows are made of cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics. The methods of pipe connection include: direct welding, flange connection, hot-melt connection, electrofusion connection, threaded connection, etc.
Produced according to the standard, it can be transformed into:
1.According to production standards, they are classified into national standards, electrical standards, water standards, ship standards, German standards, Japanese standards, American standards, Russian standards, etc.
2.According to the production methods, it can be classified into extrusion, stamping, forging, casting, etc.
90°Stainless steel elbows are mainly used as one of the connection joints for pipes. They are used for the bending connection of pipes, connecting two pipes with the same or different nominal diameters to make the pipes rotate90°.
The characteristics of stainless steel: Its strength and toughness index are the best among all types of steel. Its most prominent advantage is its corrosion resistance. Stainless steel is used in highly corrosive environments, such as the chemical industry and papermaking. Of course, its cost is also relatively high!
Precautions for using Stainless steel elbows
1.During installation, the stainless steel elbow can be directly installed on the pipeline according to the connection method, or it can be installed according to the usage location. Under normal circumstances, it can be installed anywhere inside the pipeline, but it needs to be sealed to prevent flushing leakage and have a positive impact on the pipeline.
2.When using ball valves, globe valves and gate valves with stainless steel elbows, they can only be fully opened or closed. They do not allow flow regulation to avoid sealing.
3.To store stainless steel elbows for a long time, regular inspections should be carried out. The exposed surfaces should be kept clean, and dirt should be removed and they should be neatly stored in a well-ventilated and dry indoor place. It is strictly prohibited to stack and store it in the open air. Always keep the stainless steel elbow dry and well-ventilated, keep the protective ring clean and tidy, and store it in accordance with the correct storage method.
Warm reminder: When using stainless steel elbows, many things need to be noted. Users need to use it according to specific methods and maintain it in an accurate and fair way.
Therefore, during the installation and layout of pipeline engineering, if there is a situation where the direction of the pipeline needs to be changed, stainless steel elbows should be used for conversion, and then the other end of the elbow should be connected with a stainless steel pipe. Only in this way can the direction of the pipeline be changed.
