What are the production characteristics of No. 20 steel pipe

No. 20 steel pipe is mainly used for conveying pipes, pipe piles and some structural pipes. Product specifications: outer diameter 300～3660mm, wall thickness 3.2～25.4mm.

The production characteristics of No. 20 steel pipe are:
(1) The same width strip can be used to produce pipes with multiple outer diameters;

(2) No. 20 steel pipe has good straightness and precise dimensions. The inner and outer welds increase the rigidity of the pipe body, so there is no need for sizing and straightening after welding;

(3) It is easy to realize mechanization, automation and continuous production;

(4) Compared with other equipment of similar scale, it has small dimensions, less land occupation and investment, and faster construction;

(5) Compared with steel pipes of the same size, the weld seam per unit length of No. 20 steel pipe is longer, so the productivity is lower.
