Abstract

The invention discloses a steel pipe for water delivery pipeline. The steel pipe comprises a steel pipe body, an anti-scaling coating, an antibacterial coating, a first temperature sudden drop protective layer and a second temperature sudden drop protective layer, wherein the outer surface of the steel pipe body is sequentially provided with the anti-scaling coating and the antibacterial coating from inside to outside; and the inner surface of the steel pipe body is sequentially provided with the first temperature sudden drop protective layer and the second temperature sudden drop protective layer from outside to inside. In such a way, the steel pipe has anti-scaling and antibacterial functions, and steel pipe explosion caused by outside temperature shock cannot happen.

Description

technical field [0001] The invention relates to the field of steel pipes, in particular to a steel pipe used for water pipelines. Background technique [0002] Steel pipe is a hollow long strip of steel, which is widely used as a pipeline for transporting fluids, such as oil, natural gas, water, gas, steam, etc. In addition, it is lighter in weight when bending and torsional strength are the same, so it is also widely used Used in the manufacture of mechanical parts and engineering structures. [0003] Steel pipes can be divided into two categories according to production methods: seamless steel pipes and seamed steel pipes, and seamed steel pipes are referred to as straight seam steel pipes. According to the production method, seamless steel pipes can be divided into: hot rolled seamless pipes, cold drawn pipes, precision steel pipes, thermal expansion pipes, cold spinning pipes and extruded pipes. Seamless steel pipes are made of high-quality carbon steel or alloy steel,...
