GRP Pipe

MFGIL-GRP is the first Plant in South India to manufacture Glass Reinforced Polyester (GRP) pipes, with a considerably large diameter (upto 2600 mm), on CFW Machine. This process allows the use of continuous glass fibre reinforcements in the circumferential direction. The production activities are carried out under controlled procedure with continuously advancing Mandrel process.

MFGIL has Helical Winding Process Machine with capacity 50 mm to 1000 MM Dia GRP/ GRE pipes.

General Characteristics of GRP Pipes

• Excellent corrosion resistance
• Excellent strength to weight ratio
• Very light weight
• Electrical properties - GRP pipes are non conductive, but conductivity can be introduced during manufacturing, if required, for special applications.
• Dimensional stability - While maintaining dimensional limits, the pipe laminate exhibits excellent mechanical & chemical properties.
• Low maintenance cost - almost nil.

Applications of GRP Pipes

Growing awareness of the operational cost savings and superior corrosion resistance offered by fibreglass-reinforced pipe by operations has resulted in widespread use for the following applications:

• Water transmission and distribution (potable and raw water,Irrigation)
• Sanitary sewerage collection systems and outfalls (direct buryand sliplining )
• Storm sewers
• Hydroelectric penstock lines
• Seawater intake and outfalls
• Circulating cooling water, make-up and blow down lines for power plants
• Industrial applications
• Industrial effluents
• Industrial process pipelines
• Industrial ducting
• Well-casing
• Fire protection
• Industrial wastes & effluents
• Food industries

Our Capacity
MFGIL can manufacture GRP pipes ranges from a nominal diameter of 50 mm to 2600 mm & fittings with different stiffness and pressure classes by complying to national and intentional standards.
MFGIL has in-house Pipe Design, R & D Department and a complete test facility. The unit has a fully integrated facility of manufacturing and testing of GRP pipes, as per standards. MFGIL has a production capacity of about 300 km per year.

In-house Production Testing and Design Facility 
The testing facility at our unit caters to stringent quality checks at every stage of the manufacturing process. The quality team facilitates:

• Raw material inspection
• Dimensional and workmanship
• Hydro test
• Stiffness test
• Beam strength
• Longitudinal tensile strength
• Hoop tensile test

Type test

• Long-term hydrostatic test (HDB)
• Potability of water (for potable water supply pipe)
• Strain corrosion test (sewerage, industrial waste water other than potable pipe).
