ASME B16.9 Pipe Fitting Insulation Elbow Size Chart
Long radius elbow refers to the pipe outer diameter with radius of curvature equal to 1.5 times, i.e R = 1.5D.
Short radius elbow means that its radius of curvature is equal to the outer diameter of the tube, i.e R = 1.0D
The function of elbow is to change direction or flow in a piping system. There are the 45°, 90° and 180° elbows
Elbow is a pipe fitting that changes the direction of piping. According to the Angle, there are 45° and 90°180° three most commonly used. Elbow material can be divided into carbon steel, alloy steel and stainless-steel.
According to the production method, it can be divided into pushing, pressing, forging, casting, etc.
According to its radius of curvature, there are long radius elbow and short radius elbow. Long radius elbow refers to its radius of curvature is equal to 1.5 times the outside diameter of the pipe, that is, R=1.5D; A short radius elbow means that its radius of curvature is equal to the outer diameter of the pipe, that is, R= 1.0d.(D is the diameter of the elbow, and R is the radius of curvature).
The ASME/ANSI B16.9 specification covers the dimensions and the tolerances of carbon, alloy and stainless-steel butt weld fittings.
The ASME B16.9 standard covers all dimensions, tolerances, ratings, testing, and marking for factory-made. butt-welding fittings range size is 1/2’’-80’’/DN15-2000
