Patching of the outer coating of anti-corrosion steel pipes: On-site patching should use the same epoxy powder as the pipe body Perform thermal spraying. Spraying must be carried out before the hydraulic test to avoid being unable to heat to the required curing temperature of the epoxy powder due to water in the steel pipe. If the owner requires it, solvent-free liquid epoxy coating and three-layer heat shrink sleeve (tape) can be used to repair the joints.
