90 degree socket welding elbow is a kind of pipe fitting commonly used in pipeline installation, which is used to connect two pipes with the same or different nominal diameter to make the pipe turn at a certain angle. 90 degree socket welding elbow is made of cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metal and plastic. The ways of connecting with the pipe are: direct welding (the most commonly used way) flange connection, hot-melt connection, electric fusion connection, thread connection and socket connection, etc.

It is not allowed to weld two 45 degree elbows into 90 degree elbows for use, because the elbows are the concentration area of stress on the pipes, and most of the stress of expansion and cooling deformation is released at the elbows. In addition, the weld itself should be a weak link, and the fatigue deformation will soon cause crack damage, which has a great hidden danger. Therefore, it is not convenient to plan for a while, and ultimately cause huge losses.
