Detailed Product Description

GRP pipe with sand filler are based on the successful manufacturing technology and scientific development, it is typical of reliability,safety and economy,mainly used for pressure and gravity conveying system under ground and long conveying system,they are light in weight,corrosion-resistant,long service life,low cost for operation and maintenance thus saving lots of costs of projects construction.

1.     Merits

1.     Lightness and high strength:

The unit length weight of GRP is only 1/3 of the carbonsteels,1/5 of the cast-steel pipes and 1/10 of stress rubstone pipe while compare with the same diameter pipe,and so is welcomed during transporting and the on-spot constructing.At the same time reduced the cost of hang-intallation and speed up installation.

2.     Possess excellent properties of water-fast and corrosion resistance,reduced the cost of resistance and extend the duration of usage.

3.     Excellent hydraulic property which is more prominent when referring to drainage.As reducing the cost of pipe-net pump-transporting and for the pipe-net with samd caliber,GRP retrench the cost 30-40%;when coveying the same flux GRP pipe could reduce the caliber 10-25% so that to save the investment-cost and reduce the time of pump transporting and reduce 1/3 of aforementioned items when applied during centralized or intermittent water-usage wall is always smooth just as new without filth, which is called hydraulic-smooth pipe in abroad.

4.     Pressure resistance:

 Design and produce pipes according to technique required pressure,perform 1.5 times water-pressure test according to the technical requirement.

5.     Excellent hermetical property of joint without leak and will never break so that provide the safety of the water-provide.

6.     No poison therefore can be used for drinkable water conveyance.

.Process

Controlled by computer, make lining on the mandrel according to the technique of filament winding GRP pipes.After gelling,wind the structural layer according to design pattern and thickness,spraying mortar of mixed quartz sand and resin to wind into structural layer,finally wind the protective layer.
