Commonly used coatings for steel pipeline anticorrosion

Anti-corrosion steel pipes have always been the most important part of various industrial engineering projects, but the selection of anti-corrosion coatings for steel pipes is a problem. Let's take a look at the commonly used coatings for steel pipe anti-corrosion.

Epoxy anti-corrosion coating: 1. Ring primer 2. Iron red high anti-corrosion and anti-rust primer 3. Zinc-rich epoxy anti-rust primer 4. Zinc-rich epoxy anti-rust primer 5. Mica iron epoxy anti-rust primer Paint 6. Cloud iron epoxy anti-rust primer 7. Hongdan epoxy anti-rust paint 8. Iron red workshop primer 9. Iron red epoxy deck paint 10. Epoxy enamel paints 11. Epoxy anti-corrosion topcoat 12. Ring Oxygen coal tar heavy anti-corrosion paint 13. Epoxy coal tar pitch antirust primer 14. Black antistatic oil resistant primer 15. Black anti-static oil-resistant top coat 16. Inorganic zinc silicate primer
The more authoritative foreign epoxy resin composite coating system is the American Amo 370 pipeline coating (AP370PLC), which is suitable for protecting pipelines from abrasion, harsh environmental conditions, and external corrosion. AP370PLC is a long-term corrosion barrier suitable for the transition from land to air. AP370PLC forms a chemical barrier that blocks most chemicals, including caustic soda, dilute acids, saline solutions, water, steam, and white spirit. It is a wet wrap product, so it can be used on straight pipes as well as bends, T-pipes, and other configurations. Due to its durability, the system greatly reduces scheduled maintenance.
Features: The mixing ratio is 1:1 (equal mixing)
Color: White for part A, black for part B, light gray after mixing & curing
AP370PLC kits are available in 1 quart, 1/2 gallon, and 1-gallon pail with 1 roll of fiberglass cloth tape (NOTE: 1-gallon kit covers approximately 25 square feet of pipe surface)
Continuous operating temperature: -51°C to 91°C
Use time limit/working time: 24°C, about 45 minutes
Curing time: 29°C, about 2 hours
Provides UV protection
The storage period of epoxy resin 370A & B is 2 years

Resin anti-corrosion material
1. Epoxy resin (EP): refers to an organic polymer compound containing more than two epoxy groups in the molecule, and is a synthetic resin commonly used in anti-corrosion engineering. It has excellent bonding performance, good corrosion resistance and heat resistance, low curing shrinkage, and good process performance.
2. Vinyl ester resin: the product of the addition reaction of methacrylic acid or acrylic acid and epoxy resin, easily soluble in styrene (cross-linking agent); engineering applications mainly include epoxy methacrylic acid type, is oyster modified Sexual epoxy acrylic type and novolac epoxy methacrylic type
3. Unsaturated polyester resin (UP): It is formed by polycondensation of unsaturated dibasic acid or anhydride, saturated dibasic acid or anhydride, and a diol. It is an important resin for the manufacture of fiber-reinforced plastics
4. Furan resin: It is a general term for a class of thermosetting resins made of furfural as the basic raw material and has a furan ring structure, mainly including furfural alcohol resin, furfural resin, furfurone resin, furfural-furfuryl alcohol resin, phenol-furfural resin
5. Phenolic resin: refers to the synthetic resin obtained by polycondensation reaction of phenolic compounds and aldehyde compounds. Commonly used are phenol formaldehyde resin, cresol formaldehyde resin, xylenol formaldehyde resin, and phenol furfural resin.
