Epoxy Coating:
Optimal internal pipe surface temperature is created prior to epoxy coating. Another air pressure leak test is performed. Conditioned air is then introduced into the pipe to evenly distribute the epoxy coating throughout the piping system. Following the coating application, conditioned and controlled air flows through the pipes to facilitate epoxy curing.
3PE Coating Pipe has three layer PE antisepsis structure:
the first layer with epoxy powder (FBE> 100um)
the second layer with adhesive (AD), 170 - 250um
the third layer with polyethylene (PE) 2.5 ~ 3.7mm
