Sarplast is the
world leading company in the design,
manufacturing and supply of Glass Fiber
Reinforced Plastic (GRP) pipes and
fittings with the Dual Helix Technology.
Sarplast Qatar W.L.L. has been
set up with the target to further
develop the filament winding GRP
technology and products in the G.C.C.
market of and to continue working and
increasing the experience of
manufacturing started in 1973.
Diameters in the Doha Plant are
available ranging from No. 600 mm up to
No. 3000 mm, and for operating pressures
up to 30 bars.
SARPLAST QATAR WLL. was established in Doha – State of Qatar as a joint venture among:
- AMIANTIT QATAR PIPES Co. (AQAP) leading manufacturer of (FRP/GRP) Pipes & Fittings in the State of Qatar
- Abu Dhabi Pipe Factory leading manufacturer of (FRP/GRP) Pipes & Fittings in UAE.
- Iniziative Industriali S.p.A.– SARPLAST ITALY
is located in the new industrial area
of Doha, Qatar and can its facilities
can be summarized as follows :
- Total Area: 42.000 m2
- Production Area: 4.000 m2
- Production Capacity: 18.000 Tons/year
- Production Units/Pipes: 2 lines
- Production lines Fittings: 1 workshop
- Prefabrication : 1 workshop
Characteristics of Filament Wound GRP
are formed by adjusting the relative
speed of the mandrel rotation and the
movement of the glass distributor, to
achieve the pipe predefined design,
according to the required winding angle.
Pipe properties can be varied by
adjusting the proportions of materials
which may also include high purity sand.
Main characteristics are:
internal bore which remains
Corrosion resistant in regard to the
conveyed fluids, aggressive soils
and vacant currents.

weight that allows an easy
system with large diameters for low
pressure applications as aqueducts,
sewers, sea water intake and
systems for chemical, petrochemical,
food and power industry.

Supervision for the following activities
Filament wound pipes are available in
12m lengths and installing them
guarantees their fast and practical
installation compared to many other
systems since the bell and spigot joint
makes the pipes assembly and joining
The nipple sealing test guarantees the
successful execution of the final
hydraulic test that therefore this may
also be avoided.
If the joint is also provided with
locking keys. Then the use of thrust or
anchor blocks can be reduced enormously
or can even removed completely.
Sarplast can produce in GRP a wide range
of fittings (elbows, flanges, tees
reducers, etc.) and prefabricated
spools, that are supplied ready to be
Fittings can be manufactured either by
hand lat-up, by contact molding or by
