What is a 45 degree elbow?
A 45 degree elbow is also called a "45 bend" It is a fitting which is bent in such a way to produce 45 degree change in the direction of flow in the pipe. It is used to change the direction in piping and is also sometimes called a "quarter bend".
What is JIS B2312?
This standard specifies the steel and nickel chromium ferro alloy fittings to be fitted by butt welding，mainly to pressure service pipings 1)， high pressure service pipings 2)， high temperature service pipings 3)， alloy steel pipings 4) stainless steel pipings 5) low temperature service pipings 6) and steel pipes for fired heaters 7) (hereafter referred to as “pipe fittings”).
