Formula calculation method for precision cold drawn tube weight
Sep 17, 2023
(Outer diameter wall thickness)*wall thickness]*0.02466=kg/M (weight per meter), suitable for customers who have higher requirements on precision and flatness, such as automobiles, motorcycles, refrigeration equipment, hydraulic parts, cylinders, etc., steel pipes cleanliness and mechanical properties.
Strict requirements are put forward for the mechanical properties of precision cold-drawn steel pipes, such as tensile strength, yield strength or yield point, and elongation. In addition to ensuring the mechanical properties, the chemical composition must also be guaranteed. Before leaving the factory, it must pass the hydrostatic test, crimping, flaring, flattening and other tests.
