The 8710 anticorrosive spiral steel pipe (SSAW steel pipe) involves applying a liquid epoxy coating, IPN8710 anticorrosion, to the inner wall of the spiral pipe. This coating, composed of polyurethane prepolymer, epoxy resin, and other components, is commonly utilized for daily drinking water and food transportation due to its corrosion resistance, hydrolysis resistance, and other advantageous properties. This article will talk about anticorrosive spiral steel pipe.
Two Variations of IPN8710 are Commonly Used:
- IPN8710-1:Comprising polyurethane polyethylene, modified epoxy resin, non-toxic anticorrosion pigments, fillers, and additives. Cured at room temperature, it forms a dense interpenetrating network with outstanding resistance to acid, alkali, salt, and corrosion. It exhibits strong adhesion.
- IPN8710-2A: Composed of epoxy, rubber resin modification, non-toxic anti-rust pigments, fillers, and additives. It boasts excellent chemical resistance and is non-toxic with resistance against microbial erosion.
To preserve the 8710 anticorrosive spiral tube, it is recommended to store it in a cool and dry place, avoiding direct sunlight. The usual storage period is one year, and after expiration, various tests are required before use.
While the initial discussion focused on anticorrosion for the inner wall, it's essential to consider outer wall anticorrosion for comprehensive protection:
- 3PE Anticorrosion:
Epoxy powder, adhesive, and polyethylene are fused and applied to the outer wall of the spiral pipe to create a 3PE anticorrosion layer, ensuring effective protection against corrosion.
- Epoxy Coal Tar Anticorrosion:
Utilizing materials like epoxy resin, coal tar pitch, and anti-rust pigments, this anticorrosion method offers fast drying and strong adhesion, gaining approval from many customers.
- Anticorrosive Coating:
The outer jacket features an anticorrosive polyethylene layer, sheathed onto the spiral pipe. This provides effective protection for the steel pipe, preventing corrosion and minimizing external damage to the anticorrosive steel pipe.
