Specifications

Plastic coated steel tube with steel as matrix, a new composite pipe

Supplying water plastic coated steel tube with steel as matrix, a new composite pipe through a special process in high temperature curing the walls melt spraying or adsorption of food grade epoxy powder coating or polyethylene material into.

Our company can produce a thousand varieties of plastic pipe such as seamless and welded plastic composite pipe, the largest specifications to DN1600. can produce a variety of colors:such as black, grey, blue, red, white, green and so on.

Product characteristic:

1.Coating adhesion ability of coated steel pipe is strong

Epoxy and polyethylene has the strong sorption for metals, ceramics, glass and other materials;

2.Low cure shrinkage

Epoxy resin and polyethylene coating is one of the smallest species for shrinkage between a thermosetting and thermoplastic curable plastic shrinkage (phenol formaldehyde resin 8% ~ 10%; unsaturated polyester resin 4% ~ 6%; silicone resin 4% ~ 8%). Linear expansion coefficient is very small, generally for 6 × 10-5/ °C. So the little volume can be changed after curing.

3.Good technology

Plastic powder curing have not low molecular volatile basically , so can be the low-pressure molding or contactting pressure molding.Manufacturing solvent-free, high solid, powder coating and waterborne coatings and other environmentally friendly coatings with a variety of curing agent.

4.Excellent electrical insulation

Internal and external coating plastic have good insulating performance;

5.Good chemical stability.

Excellent chemical resistance;

6.High temperature range

 

Heat resistance is generally 80 ~ 100 °C. Epoxy resin heat-resistant varieties of up to 200 DEG C or higher;

7.High mechanical strength

Anyway wear resistance, flexural, compressive, shear strength is equal to steel.

The implementation of standards:

"CJ/T120-2008" plastic coating steel pipe for water supply;

GB/T17219-1998 "drinking water distribution equipment and protective materials safety evaluation standards".
