Short on time? Let Steel Pipes sellers contact you.
In the process of manufacturing square pipes, rectangle pipes with direct shaping and molding technology, combined type rollers are used with pieces structure.
Roller sleeves are filled between roller pieces. The pieces structure is used for rollers. In the deformation region, rollers contact strip steel partially not fully, reducing the contact area and reducing the friction between strip steel and rollers accordingly.
Pipeline characteristics:
1. The fungus and microorganism in the tap water or wastewater will not attach pipeline wall.
2. The inner coating of the pipeline is smooth; the fluid friction resistance is small.
3. The pipeline inner wall has excellent corrosion resistance.
4. The outer wall of the pipe coated with the single layer of polyethylene powder, flexible, resistant to bump, with a strong resistance to soil corrosion, green.
5. The design life of the inside and outside coating is up to 50 years.
Mainly used in municipal water conservancy project (transport tap water, middle water, sewage), petroleum, chemical, natural gas, electricity, heat, sea water transport, coal and other fields. Apply to bury underground, overhead, underwater lying.
Inside and outside epoxy coated steel pipe to maximize the advantages of both steel pipe and plastic pipe. Not only have the mechanical properties of steel, high strength, high stiffness, but also have the advantages of plastic pipe, anti-corrosion, smooth pipe wall, not breeding micro-organisms, no incrustation, water resistance coefficient is small. Compare with normal steel pipe the average water supply increased by 10% -15%, reducing the power consumption of water supply by 15

Polyethylene coated steel pipe
Inner epoxy outer polyethylene anti-corrosion steel pipe is a kind of coated steel pipe, use the technique of internal spray epoxy powder, outer shower coating with polyethylene powder. The intermediate frequency-heating mode utilizes the waste heat of the tube to cure both at the same time, without separately coating the curing. Products inner coated with the food-grade epoxy, making the inner surface of the pipe more smoothly, not easy to breed microorganisms, to ensured the water quality and increased the flow rate. Outer shower coating with polyethylene powder, making the outer surface of plastic layer thickness increases, corrosion resistance is more remarkable

Weather proof double layer epoxy compound powder
Epoxy compound powder coating
Introduction
The product is a kind of weather proof double layer heavy duty epoxy compound powder, comprises of two layers of primer and finishing, to be applied directly to steel surface after sandblasted and heated. The primer layer is to provide protection for anticorrosion. The finishing layer is anti- scratch, anti-impact, anti-abrasion as the common advantage of epoxy coating, it is also featured with high shinning, uv-resistant, and superior durable, heat resistant, anti-corrosion, anti-powderization. The finishing layer is applied onto the primer layer. Two layers of powder are melted and solidified to an even, dense coating layer with solid jointing between two layers. The powder can be customized to a plenty of color with can, t be get from normal anti-corrosion layer. The coating will not fade, darken fast over time, even for the bright colors like white, light blue, pink, bright yellow.
