Composite steel pipe is what composite steel pipe classification

Composite steel pipe belongs to the cost-effective products in the steel-plastic composite pipe products, and the application field is quite wide, such as: water supply and drainage system, fire sprinkler system, gas and oil transmission special pipe network system, cable protection pipe system and other major fields.

What is composite steel pipe

Simply put, it belongs to the complex of steel and plastic, it has the common advantages of the two, such as the composite steel pipe with super compression and tensile properties. In addition, in corrosion resistance, acid and alkali resistance, wear resistance is also very good. This type of pipe also has a colorful appearance, in terms of delivery efficiency can also satisfy different areas of business.

Not only that, but most composite steel pipes now outperform other pipes in terms of hygiene standards. It will not accumulate dirt and microbes due to long time of use, thus ensuring the original nature of the fluid. It is important to know that such pipes have excellent insulation properties, and can be used in many special environments, for the protection of many wire devices and other items. This will help us reduce the chance of leakage.

And for this kind of pipe, the inner wall is smooth and flat, so that the overall construction accuracy is more smooth and simple. This kind of composite pipe can not only improve the overall construction accuracy, but also ensure the final effect of construction.

Classification of composite steel tubes

1, aluminum plastic composite pipe. Aluminum-plastic composite pipe is a layer of welded aluminum alloy in the middle, a layer of polyethylene inside and outside, and a five-layer pipe bonded by the glued layer. It has the advantages of good corrosion resistance of polyethylene plastic pipe and high pressure resistance of metal pipe. Aluminum-plastic composite pipe is divided into two kinds according to the polyethylene material: crosslinked polyethylene aluminum-plastic composite pipe suitable for hot water and high-density polyethylene aluminum-plastic composite pipe suitable for cold water. Aluminum plastic composite pipe specification is Φ14 ~ Φ32, using clamp type copper fittings connection, mainly used in building water distribution pipe and water heater pipe, the price is more expensive.

2. Steel-plastic composite pipe. Steel-plastic composite pipe is made of UPVC plastic of certain thickness inside galvanized pipe, so it has the advantages of both steel pipe and plastic pipe. The pipe specifications are Φ15 to Φ150. With copper accessories wire buckle connection, the use of water temperature below 50℃, mostly used as building water cooling pipe, the price is more expensive.

3, steel skeleton PE pipe. Steel skeleton PE pipe is a new type of double-sided anti-corrosion pressure pipe with high quality low carbon steel wire as reinforcement phase, high density polyethylene as matrix, through the mesh of steel wire spot welding and plastic extrusion filling synchronous, continuous film drawing on the production line. Pipe diameter of 50 ~ 500, flange connection, mainly used in municipal, chemical and oilfield pipe network, the price is more expensive.

4, coated plastic steel pipe. Coated plastic steel pipe is a steel-plastic composite pipe composed of polyethylene (PE) resin, ethylene-acrylic copolymer (EAA), epoxy (EP) powder, non-toxic polypropylene (PP) or non-toxic polyvinyl chloride (PVC) and other organic matter with a thickness of 0.5 ~ 1.0mm on the inner wall of the steel pipe. It not only has the advantages of high strength of steel pipe, easy connection, water impact resistance, but also overcomes the steel pipe in water corrosion, pollution, scaling and plastic pipe strength is not high, poor fire performance and other shortcomings, the design life can reach 50 years.
