Is the minimum bending radius for seamless stainless steel pipes 4d?

This post was last edited by niat8888 on 2016-11-8 08:02: Minimum bending radius. . 1D。 . . Of course, this is a elbow. . The tube is bent directly, with a radius that is generally greater than or equal to 3D. . The requirements of various standards may differ. .

There are two options for selecting the bending radius of elbows: 1. Standard elbows: The values are determined according to the specifications for elbows in \"GB/T 12459-2005 Steel Welded Seamless Fittings\", with options of 1.5D (long radius) and 1.0D (short radius). 2. The elbows manufactured are commonly known as non-standard elbows, and their bending radius can be determined in accordance with the provisions of 5.2.3 in the \"GB 50235-2010 Code for Construction of Industrial Metal Piping Projects\". For your reference, 5.3.2 The bending radius of the bent pipe shall comply with the provisions of the design documents and **current relevant standards. When not specified, the bending radius of high-pressure steel pipes should be greater than 5 times the outer diameter of the pipe, while for other pipes, it should be greater than 3.5 times the outer diameter of the pipe.

The standards may vary depending on the situation; the original poster can refer to the answers above, and I have also learned* it
