(228). Start a GRP & FRP Pipes Manufacturing Unit
Fiber Tech Grip Pipes are manufactured by widely used helical filament winding method. Grip Pipes manufactured by filament winding method utilise continuous glass strand roving impregnated with polyester resin and helically wound on rotating mandrel at a specified winding angle. The winding process is continuous in bi-directional layers until the desired wall thickness is achieved. Grip pipes manufactured by filament winding offers better physical properties in comparison with other method so Grip Pipes manufactured with helical filament winding method will have longer services life whthout affecting the cost of supply.
Features & Advantages of GRP Pipes, FRP Pipes
CORROSION RESISTANCE Fiber Tech GRP Pipes manufactured with composite material glass fibre and polyesterresin. GRP is an inert material providing excellent resistance to corrosion, high chemical resistance and high weathering resistance.
NON-TOXICITY the filament winding manufacturing technology togather with the process of polymerisation and vaporisation enables Fiber Tech GRP Pipes to be made in exact conformity to the laws in forces, governing the construction of pipe that will have to be in contact with potable water and food stuffs.
HYDRAULIC EFFICIENCY Fiber Tech GRP Pipes with very smooth internal surface provides high "c" value to carry high flow at a very low frictional head loss and offers better pumping cost & saves electricity.
LONGER SERVICES LIFE Hydraulic design basis (HDB) of Fiber Tech GRP Pipes is such that, even after continuous service of 50 years, it will be having safety factor of 1.8 times of its pressure class. Thus, Fiber Tech GRP Pipes will have longer service life, reliability and durability with much lower life cycle cost compare to C.I., STEEL, G.I. and P.S.C. Pipes.
SURGE PRESSURE High resistance to surge pressure Fiber Tech GRP Pipes provide higher resistance surge pressure with high stiffness offering very less chance of bursting of pipe due to water hammer compare to steel and C.I. Pipes.
LIGHT WEIGHT Fiber Tech GRP Pipes have lower strength to weight ratio while in comparing with other material. it is light in weigh by 1/10 of P.S.C. 1/5 of steel and 1/8 of C.I. Thus, Fiber Tech GRP Pipes provide easy and faster installation, handling, modification and repairs.
LOW THERMAL AND ELECTRICAL CONDUCTIVITY Fiber Tech GRP Pipes have excellent thermal insulating properties and there is no need for the pipes to be insulated externally to maintain the temperature inside the pipe. Even cathodic protection is also not required for GRP Pipes.

Joint
GRP Pipe joints can be divided in two categories:
- Unrestrained joint, withstand hoop pressure only.
- Restrained joint, which can resists longitudinal force and hoop pressure.
Unrestrained Joints
coupling or socket & spigot gasket: Joint this joint is provided with grooves either on spigot or in the socket to retain an elastomeric gaskets for better water tightness.
Restrained Joints
coupling or socket & spigot gasket: Joint this joint is provided with grooves either on spigot or in the socket to retain an elastomeric gaskets for better water tightness.
Restrained Joints
- Butt & strap joint: These type of joints are permanent joints and widely used in all over the world for joining the GRP Pipeline. it consists of hardening of impregnated glass, chop standard mat, woven roving mat and tissues it is laminated according to specified thickness and width depend upon th design pressure class, thus offering the continuity in hoop and axial directions.
- Fixed flanged joint
- Stub end with steel loose flange
Auxiliary Raw Materials
The auxiliary raw materials are necessary, in limited quantities, to promote or inhibit
the polymerization reactions in order to better control and select the working phases
both for pipes. Ultraviolet rays inhibitor agents are employed to increase the already
great resistance to weathering.
The main auxiliary raw materials are namely:
• Catalyst for polyester resins: 50% solution of methyl ethyl ketone peroxide in
dimethylphtalate.
• Accelerator : solution of cobalt naphtenate in styrene.
• Inhibitor : 10% solution of ter-butyl-catechol in styrene.
• Thixotropic agent : micronized silica gel.
• Solution of paraffin in styrene.
• Polyvinyl alcohol.
• U. V. rays inhibitor.
• Silica sand
G.R.P. PRODUCT CHARACTERISTICS
GRP Pipes Wall Description
The G.R.P. pipe wall consists of three layers perfectly adherent with one another, each
having different characteristics and properties in relation to their function. The
properties of chemical resistance and impermeability are, anyway, equivalent for the
three layers which are namely:
ƒ liner:
It is in direct contact with the conveyed fluid and guarantees the maximum
resistance to the chemical attack from the fluid itself. Moreover, the liner presents
an internal surface particularly smooth, without defects, cracks or delaminated
zones. The liner is composed of one glass veil and one glass mat tape resin
impregnated and is produced in two steps (inner liner and outer one) 5
ƒ filament or mechanical resistant layer:
Its function is to render the pipe wall resistant to the stresses due to the design
conditions (stresses due to the internal and/or external pressure, flexural strength
due to the external loads etc.) and generated by transport and laying operations.
The thickness of the filament depend, then, upon the design conditions. The
mechanical layer is composed of winded glass filament roving chopped glass, sand
aggregate, glass mat reinforcement, all polyester resin impregnated.
ƒ gel coat or external layer:
It has a thickness of about 0.2 mm and consist of pure resin without glass
reinforcement. It guarantees the complete impregnation of the peripheral fibers,
thus yielding the external pipe surface completely free of protruding fibers and well
finished. The external coating is always added with ultraviolet rays inhibitor in order
to prevent the nearly negligible weathering effects.
2.2 End Couplings
The pipe coupling is made by a GRP sleeve with continuous elastomeric gaskets with
double or triple lips.
2.3 Fittings
A wide range of fittings and special pieces can be manufactured in G.R.P. They present,
therefore, the same characteristics, both chemical and mechanical, of the pipes. Fittings
are manufactured manually employing male moulds or pipes pieces to be joined
together. Ends of fittings can be bell and spigot type provided with sealing gaskets or
plain type to be joined by welding to adjacent pipes or other fittings. The normal
production of the new factory includes:
- 90° or 45° bends (by moulds)
- concentric and eccentric reducers (by moulds)
- fixed flanges and stub end (by moulds)
- blind flanges (by moulds)
Moreover, other special pieces such as manholes, flanged pipes equal and reduced tees
etc. can be manufactured by welding together fittings and/or pipes sections.
