1. The site should be derusted by a detergent. In the rust removal operation, noise prevention, dust reduction and fire extinguishing measures should be taken according to environmental conditions. The descaling agent should have a protective cover and no flammable materials around it.
2. Sandblasting construction site should not use sandblasting and rust removal. When used in the field, vacuum blasting, wet spraying, etc. should be used, dust removal and sound insulation measures should be taken, and safety signs should be set within the operating range.
3. When manually removing rust, wear protective masks such as masks, glasses, gloves, etc. as needed; the site should be flat and well ventilated; the pipes should be tightly shielded and must not rust on unstable pipes.
The coating and coating process of the spiral tube uses a ball mill to prepare a coating, which produces many new surfaces after the powder is broken and has a strong adsorption capacity. When the cover is coated with a coating, it is flow coated and then dried in a 45-55 large diameter spiral welded tube furnace and then dried twice.
Use homemade graphite powder water-based paint. The coating is characterized by the use of graphite powder as a refractory aggregate, a whitening binder or the like to impart high refractoriness, strength and certain gas permeability to the coating. The coating and coating process of the embedded spiral tube. Choose 20~40 mesh magnesium olive sand, bottom sanding simple sand box.
The spiral tube itself has no life limit, and the service life is mainly related to the operating environment and production process. The operating environment of the spiral steel pipe is relatively poor. In order to prolong the service life, the outer wall and inner diameter of the steel pipe are retained.
Spiral pipe refers to a steel pipe that has been treated with anti-corrosion treatment, which can effectively prevent or slow down the corrosion caused by chemical or electrochemical reactions during transportation and use. The spiral tube can effectively prevent or slow down corrosion, prolong the service life of the steel pipe, and reduce the running cost of the steel pipe.
