The mechanical steel tube is one of the most commonly used seamless steel pipes which have hollow section but no weld joint from one end to another end. This hot-rolled seamless pipe features lighter weight as compared with round steel when the bending and twisting strength is identical. So, it is a cost effective steel pipe.

The mechanical steel tubes supplied by N-STEEL are available in various sizes. The outside diameter ranges from 1/2" to 30" and the wall thickness is SCH5-SCH160. Typical applications of this ASTM steel pipe, DIN steel pipe or JIS steel pipe are structural components and mechanical parts such as oil drill pipe, bicycle frame, steel scaffold, etc.
