ASME B16.9 buttweld elbows are manufactured in a wide range of dimensions (combinations of outside diameter and wall thickness) to fit ASME B36.10 and ASME B36.19 carbon, alloy and stainless steel pipes of any size between 2 and 48 inches (and above).
Buttweld elbows below 24 inches in diameter are produced by cutting, heating and bending seamless steel pipes; pipe elbows of larger sizes are manufactured, instead, from welded pipes or steel plates.
The three most common types of elbows in piping are the 45, 90, and 180 degrees (or return elbow), as shown in the image:
Buttweld elbows 45 and 90 degrees can be manufactured in different ways, the main ones are the “mandrel process” and the “cold forming” (other methods are the elliptical forming and the double-seam welding method).
Mandrel Process
Cold forming
Manufacter supplis strightly , of good quality and big quantity
Used to the pipes connecting ,
Petroleum, chemical, power plant, gas, metallurgy, shipbuilding, construction, etc
