The elbow is a common component in the piping system, and its main function is to change the direction of the pipe. Therefore, the elbow plays an important role in pipeline construction. There are many kinds of elbows, such as stainless steel elbows, alloy steel elbows and cast iron elbows. According to the angle of the elbow, there are 60 degree elbows, 180 degree elbows, 90 degree elbows, etc.
Knowledge of manufacturing elbows
Elbows are usually directly connected to pipes, and the metal structure of pipe fittings is often damaged during connection. Therefore, in order to have good connection quality, a groove will be set at the end of the elbow during the production of the elbow. The groove has an angle, so as not to make the elbow too thin or too thick to avoid damaging the rigidity of the elbow during connection.
Surface treatments for the elbow should be performed in the production process, and paint should be coated on the surface of elbows during the treatments, so that elbows can be stored and transported. If paint is of good quality, elbows can be separated from the air and corrosion of the elbow can be prevented.
These methods, such as pressing, roll forming and cold bending, are generally used in the manufacture of elbows. Taking cold bending as an example, this manufacturing method is to select proper pipes and mechanically bend the pipes to make elbows. This method is characterized by low costs and high production efficiency, so it can be widely used. However, pipe fittings manufactured by this method also have many shortcomings, such as the metal structure of elbows will be damaged during cold bending, which will make the elbow fragile and shorten the service life of the elbow. Thus, this elbow should not be used in the pipe with strict requirements as much as possible.
The above is some knowledge about manufacturing elbows. When you choose elbows, attention should also be paid to selecting proper components to reduce the probability of pipeline accidents.
