To calculate the 55-degree angle of a pipe elbow, you can use a protractor or an angle finder to measure the angle directly. If you are fabricating or selecting a pipe elbow, ensure that the elbow is specifically designed to have a 55-degree bend, as elbows typically come in standard angles like 45, 90, or 180 degrees. For custom applications, you may need to refer to engineering specifications or design the elbow using CAD software to ensure the desired angle is achieved.

If your elbow is a short radius it is 1 times your nominal pipe diameter. If it is a long radius it is 1 1/2 times your nominal pipe diameter.show me the exact pattern of long radius
Elbow is a fitting used to change pipe direction, 45 degrees in this case, LR is referred as "long Radius" ( normally most pipes, unless you ask for SR, short radius). Butt weld refers to welding 2 ends from two separate fittings or pipe. Both ends are beveled (30 degrees is tapered from inside pipe diameter to outside pipe diameter on pipe/fitting connections)

The take off formula of a 45 degree elbow pipe, will depend on what the pipe is on. Sometimes a 45 degree pipe will need a 90 degree right angle turn to come off.

The formula to calculate the surface area of a 90-degree elbow is A = πDL, where A is the surface area, D is the diameter of the elbow, and L is the centerline radius. The surface area of the elbow is essentially the curved surface area of the elbow pipe fitting. This formula is derived from the mathematical principles of geometry and calculus, specifically the surface area of a cylinder.

The easiest way is to find the centerline length and multiply that by the linear weight of the pipe size being used. Alternatively, this formula should give the weight of an elbow in pounds: w=0.071*pi^2*R*(ro^2-ri^2) Where: w= weight of elbow (lb) R=curve radius of elbow (in) ro=outside radius of pipe (in) ri=inside radius of pipe (in)
