Installation and use of industrial spiral steel pipes

There are strict technical requirements for the installation and use of spiral steel pipes, which must be carried out according to actual conditions and operating procedures must be followed to ensure safety and quality. During general use, spiral steel pipes need to pay attention to the following points:

First, construction preparation before the use of spiral steel pipe.
Pipe trenches must be dug, tube wells must be laid, and all kinds of spiral steel pipes and tools required, including welding machines, cutting machines, electric hammers, polishing machines, etc., must be fully prepared. A series of preparations are required before installation can begin.

Second, the installation of spiral steel pipe.
According to the drawing design, the pipe bracket is prefabricated according to the on-site conditions, and then punched according to the design and on-site, and then the groove is polished with a polishing machine, and then welded.

Third, the quality requirements for the use of spiral steel pipes.
1. The deviation of vertically installed risers should be less than 3 mm per meter, and the deviation of horizontal installation should be less than 1mm.
2. Branch pipes should not be welded at welds, and welding at bends should be avoided.
3. The welding must be straight, the weld bead is complete, and there are no burn-throughs or cracks on the weld surface.
