Surface Corrosion proofing water based paint
Coating A choice of black or clear varnish exists for coating of the OCTG material. This coating is a solvent deposited non toxic phenolic PVB that provides atmospheric resistance to oxidation for a period of 6 to 12 months.
||Internal and external Epoxy coated composite steel pipe is one of new type of composite pipe developed in China in recent years. It is coated with EPOXY inside and outisde of the steel pipe. The steel pipe is the base pipe. Epoxy resin (EP) or polyethylene (PE) were used as coating materials.

||1). Strong adhension. The epoxy or the PE has strong adhension with the minerals.
|2). Low curing shrinkage:
Epoxy resin and polyethylene paint are among the lowest curing shrinkage of thermosetting and thermoplastic plastics (Phenol resin is 8%--10%; unsaturated polyester resin is 4%--6%; silicone resin is 4%; organic silicone resin is 4%--8%;)The coefficient of linear expansion is also very small, which is generally 6 × 10 ~ (-5) / ℃. So the volume after curing has little change.
|3). Excellent electrical insulation
|4). Good chemical stability and excellent resistance to chemicals
|5). High Anti heat property. The usual anti heat range is 80~100℃.The heat resistance of epoxy can reach 200 ℃ or higher.
||It is widely used in so many industrial fields, such as fire protection, natural gas, water supply and drainage, coal mine, chemical industry, electricity, oil, medicine, industry, ocean, highway, subway tunnel, ship, agriculture and so on.
