SUS304 Stainless Steel Chemical Composition Tubing
How to manufacture tubes and pipes
Tube manufacturing starts in the steel mill where either slabs or billets are cast. Production of seamless tubes starts from billets. Large diameter and heavy-walled pipes are made from hot-rolled plate, while strip welded tubes are mainly produced from cold-rolled or hot-rolled slit pre-material.
Manufacturing SUS304 Stainless Steel Chemical Composition Tubing
Depending on the outer dimension, wall thickness and final application, there are different ways of manufacturing welded tubes and pipes. Strip welded tubes are typically made in accordance with the production route shown in Figure 1. The material is decoiled, preferably into a strip accumulator which then enables continuous SUS304 Stainless Steel Chemical Composition Tubing production.
