Internal and external coating materials generally include polyethylene (PE), crosslinked polyethylene (PEX), epoxy resin (EP) and so on.

The plastic-coated flange is corrosion-resistant, non-exudation, pollution-free, high in strength, good in pressure resistance, non-aging and non-embrittlement, suitable for harsh use environment and long in service life. Mainly used in petrochemical, electric power, light industry and other industries to transport acid liquor, alkali liquor, salt liquor, various chemicals and sewage.
