Elbow Carbon Steel is one type of pipe fitting made of carbon steel (carbon steel) used to change the direction of fluid flow (such as water, gas, or oil) in the piping system. Elbow functions to turn pipes at a certain angle, usually 45 ° or 90 °, although there are also variants with other angles, such as 180 °. Elbow Carbon Steel is widely used in various industries, including the oil and gas industry, power plants, water distribution, and pipe construction. 5D iron pipe connection radius: r3d, 4d, 5d, 6d, 7d, 8d, 10d Body Material: Carbon Steel API 5L GR.
