Steel skeleton plastic composite pipes main performance parameters:

(1) Pressure cracking stability

Take 100 ± 100 mm length of pipe sample for testing. The sample is placed between the press plates of the hydraulic press and pressed slowly. After 10-15S pressing to 50% of the pipe diameter, cracks are not happened, and the steel skeleton plastic composite pipes are qualified.

(2) Shrinkage in longitudinal dimension (100 degree, keep on 1hour)

According to the provisions of GB 6671.2 to test, the number≤ 0.4%

(3) Short-term hydrostatic strength test

According to the provisions of GB6111

When supplying water:

20°C, 1h, pressure: nominal pressure × 2

80°C, 165h, pressure: Nominal pressure × 2 × 0.71

When using gas:

20 °C, 1h, pressure: nominal pressure × 2 × 2291

80°C, 165h, pressure: Nominal pressure × 2 × 2291 × 0.71

Industrial using:

20°C, 1h, pressure: Nominal pressure × 1.5

70°C, 165h, pressure: Nominal pressure × 1.5 × 0.76

(4) Thermal stability testing

According to the provisions of 5.9 of GB 15558.1-1995, or raw material manufacturers supply.s

(5) Stress crack resistance (80°C, 8Mpa) >1000lh

(6) Elongation at break >350%

(7) Long-term hydrostatic strength (20°C, 50 years, 95%) >8Mpa

(8) Houxue test (after the pipe accumulation receives ≥3.5KMJ/m2 aging energy, it still satisfies the performance requirements of the appeal (3) and (4), and maintains good welding performance.

(9) Out-of-roundness

The roundness of the pipes should not exceed 5%.

(10) Tube bending rate

(11) Allowable bending radius of pipe, mm

(12) Linear expansion coefficient

The linear expansion coefficient of the pipe is 35.4--35.9×10-6 (1/°C).

(13) Overhead laying bracket spacing

Cross pipe: dn≤200mm, the maximum distance shall not exceed 1.6m dn>200mm, the maximum distance shall not exceed 2.5m

(21) The roughness of the inner wall of the pipe is 0.2-0.4

 

 

applications

This product is mainly applied to petroleum, chemical, municipal, shipping, firefighting and other fields for medium-pressure pipelines, submarine pipelines, electricity (light) cable ducts, deep-sea fish net cage grid.

The scope of application of the the steel skeleton plastic composite pipe:

(1) Oilfield

Oilfields collecting oil pipelines, sewage pipelines, crude oil, refined oil pipelines, oil wells, polymer pipelines, and brine treatment pipes. It is especially suitable for the transportation of medium with high sulfur content such as oil, gas and water.

(2) Municipal construction

Urban water supply and drainage, natural gas, liquefied petroleum gas and gas transportation.

(3) Ships

On-board sewage pipes, water supply and drainage pipes, ballast water pipes and other living pipe systems and structural pipe systems.

(4) Coal Mine

Coal water slurry, coal bed gas, fly ash pipelines.

(5) Mine

Slurry pipe, engineering well pipe, pumping pipe.

(6) Others

Chemicals, energy, metallurgy, non-ferrous metals, electricity, environmental protection, food and other industries use the tube.

 

 

advantages

Steel skeleton plastic composite pipe is a kind of pressure pipe. Because of its unique structure, the steel skeleton plastic composite pipe has the advantages of both steel and thermoplastic plastic materials. It also determines the superiority of the steel skeleton plastic composite pipe. 

1. Steel skeleton PE composite pipes are safe, reliable and economy. It can meet all the requirements of ordinary applications of plastic pipes, and also be used in various industries, replacing stainless steel or metal pipes.

2. Structure can be easily and flexibly adjusted by changing the diameter, spacing, plastic layer thickness and plastic type to meet different requirements of pressure, resistance, mild and corrosion.

3. Low manufacturing costs. Excellent product with low price.

4. Fast-crack resistance.

5. Good traceability. Because of the existence of steel skeleton, it can be located and searched through ordinary magnetic detection methods to avoid the damage caused by other excavation works. This kind of damage is the most destructive for pure plastic tubes and other non-metallic pipes.
