Alternative Pipe System for GRP Pipe for non pressure Applications

 

Diameter 600 to 2000 mm

 

STEEL REINFORCED PE SPIRAL CORRUGATED PIPE MANUFACTURING LINE

 

 

General Description

 

Text Box:  The diameter of the pipe is from 800 mm to 2000 mm. The obvious advantage of the new composite pipe is the high stiffness and low cost if compared with the universal buried plastic sewage pipe. The ring stiffness reached S10 to S15, which is a surprise value for other plastic pipes.

 

With the collaboration and supporting of some famous Chinese pipe manufacturers, and spends almost one year and hundreds testing and modification, finally in August of 2003, Goldstone has developed the novel steel reinforced spiral corrugated pipe successfully. The product has the same structure of COMPETITORS product and even better surface.

 

Production Character

 

u  Patented plastic-steel bonding and forming technology makes the reliable composite and high performance pipe.

u  Special designed steel bending device could form the reinforce layer easily.

u  The production line is flexible to change different size conveniently.

u  The most economy solution for large size sewage pipeline system

u  New structure spiral corrugated pipe

u  Innovation composite structure

u  Excellent ring stiffness, SN10-15

u  Perfect weight and material cost


 

 

Text Box:  Text Box:  Advantages

l  All layers of the pipe are composite under the plastic melting condition, so the welding of the layers is very safe and reliable. It is totally different from the double wall spiral pipe.

 

l  The innovative pipe provides a high stiffness, less weight and low cost.

 

l  The pipe has the same outstanding anti-corrosive property and convenient installation as other plastic pipes.

 

l  The connection of the pipe could use various joint like plastic welding, stainless steel couple and heat shrinkable couple depend on the installation conditions. The new connection solution is under developing.

We should notice that the weight of polyethylene only takes 60% of the total weight of the steel reinforced pipe. Because of the continuous raising of the oil price, the cost for polyethylene is also raised very high. But the cost of carbon steel is just about half price of polyethylene. So considering in general, the reinforced spiral pipe is a very economy solution for large size sewage pipe system.
