What kind of band saw is more efficient for seamless pipes of different diameters?

Seamless pipes of different diameters, in order to improve cutting efficiency and rational use of the machine. We generally adopt two ways to cut;

For materials with larger diameters, use single pipes for cutting;

For pipes with smaller diameters, use bundles for cutting.

Bundle cutting is a material processing technology that involves cutting a bundle or a bundle of long strips of material (such as metal bars, pipes) into multiple shorter sections at the same time. This cutting method is often used to improve production efficiency and reduce processing time because it allows multiple materials to be cut at one time instead of cutting each one individually.

Two ways of bundling

One is mechanical bundling: the pipes/bars are already bundled, just measure the bundle size and choose the appropriate machine to cut;

The second is manual bundling: the pipes need to be stacked one by one manually, which will involve the problem of feeding. Will the manually stacked pipes slip during feeding, resulting in uneven length of materials during cutting? In this case, we recommend using a sawing machine specially designed for bundle cutting to perform fixed cutting, which will have a better effect.

Bundle cutting also involves a problem, which is corner bundle cutting; if it is a bundle that has been bundled, just choose the appropriate angle to cut; for manual bundling, it is not recommended to stack too many small-diameter pipes.
