Concave-convex pipe

Abstract

The invention discloses a concave-convex pipe. The concave-convex pipe comprises a pipe body and at least one concave-convex point formed on the pipe body. The concave-convex pipe has the advantages that the manufacturing technology is simple; the cost is lower; the strength and the ductility of the pipe are improved; the concave-convex pipe also can serve as an embedded pipe of other materials; and the weight is greatly reduced, the strength is greatly increased, the related process cost is greatly reduced, and the related service life of the pipe is greatly prolonged.

Description

bump tube technical field The invention relates to a pipe material, in particular to a concave-convex pipe with high strength and good toughness. Background technique At present, as a new type of pipe, concave-convex pipe is widely used in construction, machinery and other related industries. When preparing steel pipes, Q195 or Q235 steel pipes and other related materials are generally used, and there is no relevant processing to make steel pipes. However, the steel pipes in the prior art are relatively single in shape, and their strength and toughness are relatively poor, and they are lacking as embedded pipes such as plastics and cement. Difficult to use widely. Contents of the invention In view of the above-mentioned defects in the prior art, the purpose of the present invention is to propose a concave-convex tube with high strength and good toughness, which can also be used as an insert of other materials, which can greatly reduce weight, increase strength, and re...
