Product Description

Adavantages of Plastic Lined Steel Composite Pipe

  • Excellent resistance to corrosion: With strong adhesive force, excellent compactness and sound resistance to corrosion, the inner plastic layer of the plastic lined steel composite pipe can effectively prolongs the service life of the pipeline. In general circumstances, the galvanizing coat is effectively resistant to the corrosion. But, under a bad working environment such as an acid environment the plastic lined steel composite pipe should be employed.
  • Excellent mechanical strength: With an excellent mechanical strength as the one of the hot-dip galvanizing steel pipe, the plastic lined steel composite pipe can effectively bear such outside influences as impact, bending, pressure, etc.
  • Good sanitary property: The plastic layer is nonpoisonous, tasteless, causing no pollution to water, perfectly up to the state standards for the domestic water conduit pipe.
  • Small fluid resistance: With a smooth inner wall and a small friction, the plastic lined steel composite pipe for water supply is hard to accumulate scales and has a small fluid resistance, never jamming the water flow.
  • Carrier temperature: Cold water pipe ≤60℃, Hot water pipe ≤90℃

 

Applications

  • The plastic lined steel composite pipe is extensively applied to the civil water supply, industrial water supply, fire fighting, sewage transportation, communication circuit, optical fiber cable, coal gas transportation, foodstuff process, medicine and machinery fields, especially an ideal product for the urban water supply.

This product has excellent integreted performance, such as corrosion resistance, aging resistance, impact resistance, low temperature resistance and high compressive strength.

1. Corrosion Resistance

As lined with polymer layer has a good corrosion resistance, It's very stable to various concentrations of inorganic acids, organic acids, alkali and salt (more than 95% of concentrated sulfuric acid, concentrated nitric acid and other strong oxidizing acids except)

2. Aging Resistance

Lined with polymer layer of the matrix material by adding modifiers, crosslinking agents and a number of features, so that the lining internally generated low-polar molecules of saturated aliphatic hydrocarbons cross-linked structure, and enhanced resistance to stress cracking, making the product has very good anti-aging performance.
3. Impact Resistance and Low Temperature Resistance

Due to the low brittle temperatue (-70 ~-60degree celsius) of lining material, supple molecular chain, it's applicable to work within the scope of -60~100 degree celsius, and impact resistance improved.

4. High Compressive Strenght

As the polymer-lined composite steel pipe chosen high-quality steel tube as the base body, it can withstand the pressure of -0.07 ~ 2.5 Mpa

5. Light in Weight, Easy Installation

As the substrate using thin-walled steel pipe, the weight is relatively light, flange connection, flexible pipe joint connection and welded connection can be used during installation.

Application:

This product has excellent integreted performance, such as corrosion resistance, aging resistance, impact resistance, low temperature resistance and high compressive strength. It can be widely used in chemical, electric power, metallurgy, pharmaceutical, food, paper making, environmental protection, electroplating, and so on. 

It's very stable to various concentrations of inorganic acids, organic acids, alkali and salt (more than 95% of concentrated sulfuric acid, concentrated nitric acid and other strong oxidizing acids except). Within the scope of -60~100 degree celsius; it's the ideal anti-corrosion material to replace the enamel, stainless steel and glass lined steel.

Specification:

Diameter: PI 57- PI 630

Thickness of polymer lined layer: 2-5mm

Length: <=10m
