Application of PFA Valves:

• Air, gaseous, and liquid applications requiring bubble-tight service
• Low-point drains and high-point vents in liquid, gaseous, and other fluid services
• Instrument root valves
• Cooling water and feedwater systems
• Steam service

Corrosion resistance :

• The life span of the FRP/GRP pipes is good as there is no internal nor external corrosion, once the appropriate resin is selected for particular operating conditions & 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 for 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 in reduced erection cost.
• This system has an 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 the below table.

Fire Retardant properties :

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