Since the middle 1980’s underground huge diameter
composite piping has kept on growing in usage and applications. Technological improvement
in the corrosion resistance, filament winding process, strong market forces and
education outreach has contributed to the fame of fibreglass pipe. Definitions
of what comprise large-diameter pipes can differ, but in general, they have
ranges from 12” to 14’ in diameter. The whole concept of fibreglass has gained
a new name. Fibreglass Reinforced Plastic items have their unique value that
the demand of it has only grow.
Composite, or fibreglass pipe, has been
utilized in a wide range of industries such as petrochemical, power generation,
and desalination. Fibreglass pipe is resistant to corrosion. It has a
life cycle that often crosses 30 years, and has become highly desirable as a substitute
to metal alloys and steel, concrete and ductile iron.
It was seen as a specialty product, for its
capability to resist an attack from sulphuric acid, it has now become a benchmark
material, if not the standard in major market segments for quite a
lot of reasons. For example, fibreglass has been used in power plant
cooling water systems, drinking water project, feed lines, irrigation systems
for agriculture, and pressure sanitary sewers systems, penstock for
hydroelectric power plants, gravity, and pipeline rehabilitation “slip
liners”. Over twenty years fibreglass has started to rise above its
early stereotypes as a one-trick material (e.g. corrosion resistance) and has
shown its value as a commercial material, offering an overabundance of end-user
advantages.
The key reasons for Fibreglass composite poles and fibreglass pipes increased usage and
fame are key benefits such as dimensional stability, high strength-to-weight
ratio, good mechanical properties, low installation costs, effortlessness in
the process of installation, low maintenance cost, and all round durability in extreme conditions. Likewise,
another advantage of fibreglass pipe is it has an even and smooth inner surface
in comparison to usual construction products.
When making an underground large diameter pipe system many
things need to be taken into account; burial loads, local soil conditions,
deepness of water table, live loads, operating temperatures and deflection
because of burial stress to name a few. Designing a proper underground
piping structure is a highly complex procedure that contains extensive estimates
and calculations. The experienced professionals should always be present while
making glass reinforced plastic moulded products.
