A butt weld 45 degree long radius elbow is a type of pipe fitting that is used to change the direction of the flow in a piping system by 45 degrees. It is designed with a long radius, which means that the curvature of the elbow is relatively gentle, allowing for a smoother flow of fluid through the system. Kimpalan punggung 45 degree long radius elbows are made by welding two pipes or tubes together at a 45 sudut darjah, with the weld seam being flush with the surface of the elbow. They are commonly used in industries such as oil and gas, petrochemicals, and power generation to connect pipes and redirect the flow of fluids around obstacles or through corners.

45 Formula Memotong Siku Darjah
- R1 = tanda jejari siku 1
- R2 = tanda jejari siku 2
- R3 = tanda jejari siku 3
EC = Pusat Siku
OD = Daimeter Luar
R2 = Penandaan Jejari Kedua-dua Sisi
45 Formula Lepas Siku Degree
(R1) – jadi x 1 x (SPR – 1/2 DARIPADA) x Deg = jawapan
(R2) – jadi x 1 x EC … x Deg = jawapan
(R3) – jadi x 1 (SPR + 1/2 DARIPADA) x deg = jawapan
