Steel Framed Reinforced HDPE Composite Pressure Pipe (DN50-DN500)

It's a new kind of high density polyethylene pipe which is reinforced by a steel wire mesh skeleton. The manufacturing process is use spot welding crossing steel wire to make it a net-cylinder structure as reinforcing part and continuously extrude HDPE as the stuffing material to this structure on producing line at the same time, just like reinforced concrete structure.

1. Structure
It's a new kind of high density polyethylene pipe which is reinforced by a steel wire mesh skeleton. The manufacturing process is use spot welding crossing steel wire to make it a net-cylinder structure as reinforcing part and continuously extrude HDPE as the stuffing material to this structure on producing line at the same time, just like reinforced concrete structure.
This combination makes the pipe far stronger than standard HDPE pipe and more flexible and corrosion-resistant than steel pipe. Many of its inherent characteristics are far superior to those of HDPE or steel pipe.

2. Material
The stuffing material of steel reinforced HDPE pipe and fitting is PE 80 (piping class), and we use high quality low-carbon steel wire as the reinforcing part of pipe and Q235 steel sheet for fitting.
3. Characteristics
A. Excellent corrosion resistance
As generally acknowledged anti-corrosion material, PE has excellent corrosion resistance to nearly 275 kinds of corrosive medium, such as non-oxidizing acids, alkali and saline solutions.
B. Super hydraulic performance
The absolute roughness jus is 0.01mm only, but the steel pipe is 0.2mm, so the flow resistance is small and the conveying capacity is obviously higher than the steel pipe under the same condition.
C. Good flexibility and anti-seismic property
The steel framed reinforced PE composite pipe has moderate elastic modulus, so it has excellent adaptability to the nonuniform settlement foundation and ground displacement. The good anti-seismic performance will maximum reduce the cost of losses when earthquake happen.

D. Lighter weight and easier installation
The density of steel framed reinforced PE composite pipe account for 40% of steel pipe, we don't need the lifting equipment on site when we install small caliber pipe and save bend fitting cause the pipe laying will follow the topography to the general undulating land. And the requirements of trench digging is less than steel pipe.
E. Super abrasion resistance
Generally, the abrasion property of polyethylene is super than normal metal material and this dedicates the abrasion resistance feature of steel framed reinforced PE composite pipe is exactly better than normal steel pipe.
F. Excellent heat preservation property
The basic stuffing material of steel framed reinforced PE composite pipe is polyethylene, so the Thermal conductivity coefficient of PE is 0.43W/m degree, and the steel pipe is 2.5 W/m degree, nearly to 1.7%, so the hear preservation property is very good, and don't need any heat-insulation treatment even overhead in the fields of no temperature requirements.

G. Outstanding hygienic character
PE material is nontoxic, this is a common sense to all of us and being widely used in food industry. The steel framed reinforced PE composite pipe use PE as basic stuffing material have passed each test of the National Preventive Medical Association and get the Healthy Permit for portable water conveying, and our pipe can meet the requirements of Food Hygiene Law and Healthy Evaluation. And the same time, the inner surface of our pipe is bacteria free and electrochemistry corrosion free, no secondary pollution.
H. Working lifetime is longer and comprehensive cost is lower
The features of PE material ensure working lifetime of steel framed reinforced PE composite pipe is much longer and comprehensive cost much lower than normal steel pipe in the fields of conveying corrosive medium.
