Definition and classification
definitionPlastic-coated steel pipe, also known as plastic-coated pipe, steel-plastic composite pipe, plastic-coated composite steel pipe, is a steel-plastic composite steel pipe with a layer of plastic anti-corrosion layer welded on the inner surface or inner and outer surfaces of the steel pipe through spraying, rolling, dipping, suction and other processes.。
Classification: According to different coating materials, it can be divided into polyethylene coated steel pipe, epoxy resin coated steel pipe, etc.。
Features and Benefits
Strong corrosion resistance: The plastic coating on the inner and outer surfaces can effectively prevent the metal pipe from direct contact with the external environment, avoid corrosion and rust, and maintain good performance in harsh environments such as humidity, acid and alkali2。
Good wear resistance: The outer plastic coating has good wear resistance and can withstand high friction. The surface is not easy to wear out after long-term use.2。
Small fluid resistance:The inner wall is smooth and the friction coefficient is low, which can effectively reduce the resistance of fluid flow in the pipeline, help reduce transportation costs and improve transportation efficiency2。
Environmentally friendly and pollution-free: Made of environmentally friendly plastic materials, it is non-toxic and odorless, will not pollute the environment, and the production process also meets environmental protection requirements2。
Good insulation performance:The coating itself has good electrical insulation and will not cause electrical corrosion. As a protective tube for wires, it will not leak electricity and can also effectively shield external signal interference1。
High compressive strength: The internal structure is tight and supported by steel pipes, which can withstand high pressure. The maximum pressure can reach6MPa, suitable for conveying high-pressure gas, liquid and solid particles13.
Technical Parameters14
Universal Color: Black, gray, blue, red, white, green, etc.
Coating thickness:The PE (modified polyethylene) coating thickness is 400μm-1000μm, and the EP (epoxy resin) spraying thickness is 100μm-400μm.
Coating method:PE is hot-dip plastic and EP is internal and external spray coating.
Product Specifications:DN15-DN1660.
Ambient temperature:-30°C to 120°C.
Connection:Thread(DN15-DN100), groove (DN65-DN400), flange (suitable for any diameter), welding, bimetallic connection, socket, pipe joint, sealed connection, etc.
