EPOXY COATED STEEL PIPE
Introduction 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.
Execution standard GB/T3091-2003 Low pressure fluid transmission welded steel pipe
GB/T5135.20-2010 Automatic sprinkler fire fighting epoxy coated steel pipe 
GB/T8163-1999 Fluid transmission seamless steel pipe
 GB/T28897-2012 Steel-plastic composite steel pipe
SY/T0315-2013 Technical specification for external coating of fused epoxy powder steel pipe
CJ/T120-2008 Water supply epoxy coated composite steel pipe     
SY/T0457-2000 Technical standurd of liquid epoxy internal coating for steel pipeline.
Size Size: 20mm---914mm  WT: 1.5mm--10mm
Length 6m,12m, or the random length
Type of pipe ERW welded steel pipe, spiral steel pipe, seamless steel pipe, ss stainless steel pipe
Grade of the Coating Ordinary Coating: 250μm or so
Reinforced Coating: 300--500μm or more
Packing first layer: transparent plastic cloth
Second layer: It will be wrapped with thick plastic cloth
Type of connection Grooved ends or it is threaded on both ends or it is connected with flange.
Characteristics 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 80100.The heat resistance of epoxy can reach      200 or higher.
Application 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.
