Application requirements:
1. Remove the oil, grease and other impurities on the external surface of the steel pipe by suitable means before application.
2. Preheating the steel pipe to 40-60℃ to drive away moisture before shot blasting.
3. Shot blast cleaning up to grade Sa21/2 of the GB/T 8923-1988—Rusted and derusted grade of steel material surface before coating, and the anchor pattern depth should be within 40-100µm.
4. Coating should be conducted within 8 hours after surface pretreatment, while rust reappearance or surface recontamination, the surface pretreatment must be conducted again.
5. Preheating temperature of the steel pipe should be within 180-250℃, not more than 275℃.
6. Powder coating should be sprayed on to the pipe by electrostatic or venturi spray, up to the required thickness. And curing process should be conducted according to the indicated curing temperature and time. Coating thickness requirements as follows:
