Low price for Spiral Penstock Pipe - FRP SERIES PRODUCTS – TOP-METAL

Short Description:

Corrosion resistance : Life span of the FRP/GRP pipes is good as there is no internal nor external corrosion, once appropriate resin is selected for particular operating condition& is appropriately supported externally you can easily expect a life span of 15-20 years. It is suitable for weak to strong acids from alkaline chemicals to saline water & solvents. No requirement of external epoxy coating. Weight : The weight of the FRP pipes is much lesser than the corresponding...

Low price for Spiral Penstock Pipe - FRP SERIES PRODUCTS – TOP-METAL Detail:

Corrosion resistance :

Life span of the FRP/GRP pipes is good as there is no internal nor external corrosion, once appropriate resin is selected for particular operating condition& is appropriately supported externally you can easily expect a life span of 15-20 years.
It is suitable for weak to strong acids from alkaline chemicals to saline water & solvents.
No requirement of external epoxy coating.

Weight :

The weight of the FRP pipes is much lesser than the corresponding MS or concrete pipes thus easily transportable & erected resulting into reduced erection cost.

This system has excellent strength to weight properties. When the ratio of strength per unit of weight is considered, GRP/FRP composites surpass iron, carbon and stainless steel as shown in below table.

Material	Density (g/cm³)	Tensile strength (Mpa)

GRP/FRP	1.8	1400
Ductile iron	7.6	420
Steel	7.83	1034

Fire Retardant properties :

Pipes can be specially manufactured with fire retardant properties for fire fighting application.
Industries can use FRP/GRP pipes made from fire retardant resin inorder to reduce the possibility of the pipes themselves catching fire at the same time getting desired pressure in the system without fear of lekage due to corrosion which is the most common phenomenon in mild steel pipes.
