Abstract

The invention relates to the technical field of pipeline conveying equipment, in particular to a protective steel pipe. The protective steel pipe comprises a pipe body which is sleeved with a protective cover. The protective cover is in a net shape, and the parts at pitch points are in a hemisphere shape. Due to the fact that the pipe body is provided with the protective cover, the protective cover is in the net shape, and the parts at the pitch points are in the hemisphere shape, the protective steel pipe plays a role of protecting the pipe body while the firmness of the protective steel pipe is improved, the external force is resisted, the overall strength of the pipe body is improved, and cost is saved.

Description

technical field [0001] The invention relates to the technical field of pipeline transportation equipment, in particular to a protective steel pipe. Background technique [0002] In the chemical, pharmaceutical and other industries, a large number of stainless steel pipes are used for corrosion resistance. In the process of use, in order to make the stainless steel pipe have a certain strength, the pipe wall of the stainless steel pipe is thicker, so that the amount of stainless steel pipe is larger. , resulting in higher cost and increased cost. Contents of the invention [0003] In order to overcome the disadvantages of low strength, wall thickness and high cost of existing stainless steel pipes, the invention provides a protective steel pipe. [0004] The technical solution adopted by the present invention to solve the technical problem is: a protective steel pipe, including a pipe body covered with a protective sleeve. [0005] According to another embodiment of the p...
