Sulaiman Alqudaibi Co. for GRP & Plastic

Products is a Subsidiary of QDB Holding,

a leading Kuwaiti industrial & commercial

holding company.

It was founded by the late Sulaiman Ahmed

Alqudaibi in 1954. A man with great feel and

vision for business. Each of the QDB Holding

Subsidiaries is a pioneer in the services and

products it offers.

The company was, in fact, the first to

manufacture FRP water tanks by machine

method, in the Middle East. Since then, a

policy of diversification has been pursued,

with a move into high quality RTR Pipes and

Fittings, as well as polymer concrete products.

In 2005, the company was included in the

KOC’s approved list of manufacturers of GRP/

GRE/RTRP/FRP pipes and fittings.

Our pipes are manufactured by CNC fully

controlled filament winding machines. In

addition to the filament winding machines,

we can also manufacture GRP/FRP/RTRP

pipes, using our state of the art CFWcontinuous filament winding machine, which

can manufacture pipes up to 4000mm in

diameter.

The same GRP pipes are used to produce

our previously patented polymer concrete

jacking pipes which are used for micro

tunneling works.

These pipes consist of GRP liner, encased in

high strength, and corrosion resistant polymer

concrete. This material is a composite of

unsaturated polyster resin and carefully graded

inorganic fillers/aggregates.

Alqudaibi has supplied its RTRP/GRE/GRP Pipes

& Fittings to various projects of the KOC, KNPC,

Ministy of Public Works (MPW) and Ministry

of Electricity & Water (MEW). We have also

exported our products to Oman, Syria & Libya.

We have supplied both onshore and offshore

RTRP/GRE/GRP Pipes & Fittings.

Al-Qudaibi’s jacking pipes and polymer concrete

manholes of varying types have been installed

throughout Kuwait and the Middle East for

various projects of the Ministry of Public Works,

including sewerage, desalination and waste

water lines. In addition to that, our Polyglass

Jacking Pipes have been exported to Saudia

Arabia, Oman, Qatar, Iran, and Singapore.

As in our continuing quest of diversification,

QDB Holding has set up a plant to manufactureits own resin, comprising of Orthophthalic,

Isophthalic and Vinylester resins.

The company has on its staff, capable engineers

of various disciplines and diverse nationalities,

all led by an energetic CEO –

Mr. Ahmed S. Alqudaibi.

Polyglass - Jacking Pipes

Alqudaibi’s range of polymer concrete jacking

pipes are mainly used for underground sewage

lines.

They have the strength of polymer concrete and

corrosion resistance of GRP. They are Ideal for

installation using the state of the art «No-Dig /

Micro Tunneling» methods.

Using only a thin GRP pipe a s a permanent struc-

tural liner, and then surrounding it with Polymer

Concrete, the two materials combine to give a

low cost composite Polyglass pipe.

The two materials bond together in a

Polyglass pipe and become an integral

part of each other. The result of which is

a pipe having high strength a nd still com-

bining the impervious, corrosion resis-

tance and strength of GRP.

The Process of manufacturing the Poly-

glass pipes is very simple. By using the

two materials to their optimum, we have

reduced the manufacturing costs to a

level, which makes Polyglass pipes the

lowest cost and strongest GRP pipe in the

market.

Product Range

The Polyglass Jacking Pipes are

manufactured in standard lengths

of 2000mm*.

The Polyglass Jacking Pipesare manufactured in diameters

ranging from 300mm to 2400mm*.

* Other sizes and lengths can be made

upon request.

Typical Properties of Polymer Concrete

Corrision Resistance of the GRP Liner

GRP (Glass Reinforced Plastic) has been

accepted and used as a pipe material for over

thirty years. Its use being well documented.

The corrosion resistance of GRP is second tonone. It has the ability to work at high or low

temperatures in very corrosive environments.

Benefits of Jacking Pipes

Technical• Inherent strength of lining.

• Smooth internal finish giving good flow

characteristics.

• No requirement for secondary lining.

• Considerably less joints than a segmentaltunnel.

• Prevention of ground water ingress by use

of pipes with sealed flexible joints.

• Provision of invert channels in larger pipes

to contain the dry weather flow of a sewer in

a combined system.

Economical• Less affected by weather condition

• Less risk of settlement

• Minimal surface disruption

• Minimal reinstatement

• Reduced requirement for utilities diversions

in urban areas

Microtunnelling Technology

Microtunneling technology has developed rapidly in recent years and

reached a high standard worldwide because it is environmentally

friendly and cost effective. Microtunneling projects to be successful

require high-quality, high strength jacking pipes which are easy to

install. The jacking technology (NO DIG technology) in connection

with an optimum product, give plenty of advantages to the owner of

subterranean infrastructure projects as well as to the construction

companies

Advantages of Polyglass Pipes with Microtunnelling

• Minimal surface disruption and reinstatement.

• Micro Tunnelling will not harm existing vegetation.

• No groundwater lowering required.

• Mobility above ground is not affected.

• Construction work does not depend on the weather.

• High degree of reliability and cost effectiveness.

• Optimum tunnelling performance in complex

geological conditions.

• In busy urban centers, trenchless operation will not interfere with

pedestrian and motor traffic movements.• Micro Tunnelling is an inherently safer method than open trench

construction or when considering the risks associated with deep, large

section, open excavations.

The polymer manholes made by Alqudaibi CO have

proven to be corrosion resistant given that they

do not have cement in them. They are also totally

free of the cracking, de-lamination and various

problems which can cause lined manholes to fail.Polymer manholes are resistant against the sewer

gases created in heated soils or by elevation

changes. The polymers can also be individualized

to fulfill the requirements of specific corrosive

elements.

Polymer Concrete VS ConcreteConcrete manholes are formed using cement,

aggregates and water. The sulphuric acid (H2SO4)

which is present in any sewer system devours the

cement leaving behind only the a ggregates.

On the other hand, polymer concrete manholesdo not utilize any cement nor water in their

production.

They are formed using unsaturated polyester resin,

sand, gravel, and non-mineral fillers. This unique

combination of products gives polymer concrete

manholes their outstanding corrosion resistant

and elastic properties.

Polymer Concrete Manholes

Shaft Pipe These are an integral part of almost all manhole

systems. They are basically polymer concrete

cylindrical shafts which are attached to the top

of the manhole to level the manhole system

to the ground level. Al-Qudaibi›s shafts are

manufactured in different sizes and lengths,

depending on the manhole diameters & depth.

Adaptor Plate/Cone The adaptor plates/cones serve as a converter

within the manhole system. They facilitate

the conversion of shafts with large diameters

to shafts with smaller diameters.

Adapter plates/cones may seem small as

compared to the entire manhole system,

however, they are extremely essential

because they make the system flexible to

have manholes with large diameters yet

follow the standards of a specific country

which require smaller diameters at the

ground level of the manhole system.

Manhole Applications• Sewer Systems (urban and industrial)

• Irrigation Networks

• Water supply lines• Waste water treatment system

• Seawater outfalls

• Transport of corrosive fluids

• Industrial sewage

13



Easy Installation Benefits• Installation is comparable to that of an old

fashioned concrete manhole.

• Polymer concrete manholes provide for simplehandling with fewer labors since high durability

components makes it possible for a thin wall

design and consequently significantly less

weight.

• No requirement for welding of liners or coating

of the manhole.

Product Strength• The material properties of Alqudaibi’s polymer

concrete manholes adhere to the material

properties specified by ASTM D6783 & DIN16946

• As a result of high compressive and flexural

strengths and the polymer concrete manholes

can be made with thinner walls.

• High tensile strengths of polymers negate the

requirement for reinforcing steel.

Cost Benefits•

Thin walls mean a lighter product with lessfreight and installation expenditures

• Longer service life
