What Does Composite Pipe Mean?

Composite pipes are made from unreinforced thermoplastics like high density polyethylene (HDPE), polyvinyl chloride (PVC), polypropylene (PP), fiber reinforced plastics (FRP), and glass reinforced plastics (GRP). Composite pipes are resistant to corrosion and have stronger mechanical properties. For equivalent size and thickness, composite pipes are stronger and sturdier than unreinforced pipe materials. They are better able to resist forces applied during the process of installation, allowing them to be installed deeper and drawn with greater force. These pipes are widely favored in trenchless technology because they are easier to install.


Trenchlesspedia Explains Composite Pipe

Composite pipes can be manufactured to specific needs depending on the conditions to which it will be subjected. They can also be cut into desired lengths of segments making it convenient to install. They can be made strong enough to withstand structural settlement, high surge pressure and seismic loads.

These pipes have low coefficient of thermal expansion, thus limiting pipe movement, making it an ideal material to be used in places with high temperature variation. These pipes are non-corrosive; do not require cathodic protection and are resistant to acidic and sulphurous sewer environment. The smooth internal surface of these pipes prevents buildup of solid material, and the growth of bacteria and microbes, eliminating conditions like tuberculation. Clearing blockages using pressure jets and other methods is easier in composite pipes than in pipes of other material.

The lifespan of compitise pipe is between 50 to 100 years.
