Embodiment Construction

[0013] Such as figure 1 A large steel pipe 1 is shown, comprising: a cylindrical tube, paint 3 sprayed on the outside of the tube, the tube has two ends 11 and a middle part 12, and the two ends 11 have surrounding The software on its outside 4. The soft body 4 is a straw rope, and the middle 12 is not surrounded by the soft body 4 .

[0014] Such as Figure 2 to Figure 4 Shown, a kind of painting method of large-scale steel pipe, it comprises the following steps: 1) provide a cylindrical large-scale steel pipe 1; 2) stick scotch tape 2 on the two ends 11 of large-scale steel pipe 1; 3) all outsides of steel pipe 1 Spray paint 3; 4) Remove the scotch tape 2. Described paint 3 is black paint. The 2 places where the scotch tape is pasted are the joints between the large steel pipe 1 and another matching steel pipe. The large steel pipe 1 is used to transport oil, natural gas or sewage. The paint 3 can resist external corrosion.

[0015] Such as figure 2 As shown, the la...

Abstract

A large steel tube comprises a cylindrical tube barrel and paint sprayed on the outer side of the tube barrel. The tube barrel is provided with two end portions and a middle portion, and soft bodies surrounding the outer sides of the two end portions are arranged on the two end portions. The soft bodies are sleeved on the painted outer side so that the paint of the large steel tube is prevented from being bumped peeling off in transportation.

Description

【Technical field】 [0001] The invention relates to a large steel pipe, in particular to a paint protection device for the large steel pipe. 【Background technique】 [0002] Large steel pipes can be used in underground pipelines, petroleum, natural gas, steam heating, hydropower stations, sewage treatment plants, thermal power plants, water supply and drainage, etc. Large-scale steel pipes are used under these extremely harsh conditions. Due to various reasons, the outer wall of the large-scale steel pipes will be corroded, so it is necessary to spray paint on the outside of the steel pipes to protect the large-scale steel pipes. After the large steel pipe is sprayed with paint, the large steel pipe needs to be transported. Since it will be in contact with other objects during transportation, this will inevitably cause the paint to fall off. [0003] In view of the defective of above-mentioned technology, be necessary to improve its design really. 【Content of invention】 [...
