Steel Plastic Composite Pipe made in China

1. construction: suitable for building water supply project, the municipal water supply system, town gas delivery system.

2. power engineering: suitable for highway, power wire, corrosionenvironment of power threading system.

3. industrial areas: used in petroleum, chemical, parmaceutical, food,mining and other fields

1. the tensile strength of 275 ~ 320MPa, pure plastic tube is 7 ~ 8 times.

2. the thermal conductivity coefficient of 0.46 ~ 0.57W/m.k, about1/100 of steel pipe, close to the thermal conductivity of plastic pipe.

3. the linear expansion coefficient of linear expansion coefficient is 1.2 × 10-5/ °C,pure plastic pipe of 1/10 ~ 1/12.

4. the hydraulic performance of steel-plastic composite pressure pipewall roughness is 0.007mm,the inner wall is smooth,fluid transportation,small resistance loss,no fouling,the structure of rigid-flexible integration, can quickly eliminate the impact of the pipeline system pressure,does not produce water hammer noise.

5. steel corrosion resistance performance of composite pressure pipeinner and outer layer of polyethylene is a non-polar materials,chemical properties are very stable at room temperature,insoluble in any knownsolvents,corrosion resistant to various acid,alkali,salt solution.

6. the health properties of steel-plastic composite pressure pipe non-toxic,conforms to GB/T 17219 standard

7. since the tracer can use magnetic metal detectors pursuit,no need tobury tracking or protect mark,can avoid the mining damage,provides great convenience for the repair and maintenance.

8. the service life of the normal temperature,pressure range,can be used for 50 years.

9. mechanical connection steel-plastic composite pressure pipeconnector is mechanical,and the internal and external spray treatment,has the bearing capacity and anti-corrosion ability,higher than the pipe has the advantages of convenient installation,good sealing performance
