Description
45 degree elbow is a pipe fitting that can change the flow direction of liquid or gas in a piping system.
Its proportion in elbows can reach 70-80%, accounting for a considerable proportion in all pipe fittings, which shows its importance in pipes.
When using a 45 degree elbow, a certain slope is formed at the corner, which plays a buffer role. Even if the water flow is large and mixed with foreign matters, the impact on the pipe wall at the elbow will be greatly reduced.

Characteristic
45 degree elbow cannot be welded together into a 90 degree elbow because the elbow is the stress concentration area on the pipe, and most of the stress of expansion and cooling deformation is released at the elbow.
In addition, the weld itself should be a weak link, fatigue deformation is easy to cause crack damage, and buried a great hidden danger.
The specifications of 45 degree elbow are dn10, DN15, DN20, DN25, DN32, Dn40, DN50, DN65, DN80 and DN100.
It is divided into 3000lb, 6000lb, 9000lb or sch80, sch160 and XXS according to the pressure level.
Application
45 degree elbows are used in oil and gas pipeline engineering, natural gas pipeline engineering, chemical plants, power plants, shipyards, pharmaceuticals, dairy products, beer, beverages, water conservancy, etc.
