Q195 Steel Based Fire-Fighting Plastic-coated Tube

Q195 Steel Based Fire-Fighting Plastic-coated Tube

Fire-fighting plastic-coated composite pipe:

Standard: GB/T 5135.20-2010 Automatic Sprinkler System, Part 20: Coated Steel Pipe

Material: steel pipe as the base pipe, including: Q195, Q235, 10#, 20#, etc. (Seamless steel pipes will be used if pressure is required)

Stainless steel materials cannot be used, and the heating temperature is very high. When heating with ordinary carbon steel equipment, the surface adhesion is too low, and the surface of the steel pipe is difficult to adhere to the coating, so many materials are not suitable for base pipes.

Advantage:

1. Hygienic, non-toxic, no fouling, no microorganisms, and guarantee of fluid quality

2. Resistant to chemical corrosion, soil and marine organism corrosion, cathodic disbondment resistance

3. The installation process is mature, convenient and fast, and the connection is similar to ordinary galvanized pipe

4. Good weather resistance, suitable for harsh environments such as deserts and saline-alkali

5. Smooth pipe wall, improve conveying efficiency and long service life

Large diameter plastic coated steel pipe:

Large-caliber plastic-coated steel pipe is an upgraded version of traditional steel-plastic pipe and galvanized pipe with high cost performance. It has the comprehensive characteristics of high strength, high extensibility, good low temperature brittleness, small expansion coefficient of steel pipe, and plastic pipe corrosion resistance, abrasion resistance, and low fluid resistance. It is a new type of water supply and drainage, anti-corrosion green Large-caliber pipes are being used more and more widely in various domestic industries.

At present, the domestic largest diameter polyethylene plastic-coated pipe has exceeded 3200mm, and the specifications above 2200mm are coated with solvent-free epoxy. It is widely used in seawater treatment, quicksand engineering, ocean engineering, chemical sewage disposal and other projects. It has the advantages of high strength, good toughness, anti-aging, corrosion resistance, long service life, and good combination with insulation layer.
