What is the difference between pipe bend and pipe elbow
Pipe elbows and pipe bends are used to change the direction of existing pipe.The terms “elbows”and “bends” are often used interchangeably,though they are not necessarily the same.What is the difference between pipe bend and pipe elbow?
According to manufacturing process:
The process of seamless pipe elbow has hot push,cold push and hot press;the process of pipe bend has medium frequency bending,hot pushing and numerical control bending.
The most commonly used elbows in pressure pipes are carbon steel alloy steel for hot pushing,and stainless steel for cold pushing.The most common process for pipe bend is medium frequency bending.
According to the R radius:
The R radius of the elbow is the specified value,that is,there are parameter values in the standard.For example,the 10″ long radius elbow R is 381mm,the short radius is 254mm.And the bend is different,the same 10″ bend as long as R ≥3D as long as the pipe is long enough,such as 3D10″R is 762mm,as long as it is the actual working conditions,800mm 1000mm 1005mm can be customized.
Difference in scouring strength:
The R of the elbow is different from the bend.
The strength of the small R that is washed when passing through the medium is definitely higher than that of the large R.
That is to say,the 1.5D elbow is more powerful than the 1D elbow.The bend is more resistant to scour and wear than the elbow.
