What is a 90 degree elbow?
A 90° elbow attaches readily to pipes of various materials like plastic， copper， cast iron， steel， lead， rubber etc. In other words， the 90° elbows are used to provide a joint between two pipes at right angles to each other. They are used as railing ends or corners on a level installation.
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”).
