• Long effective service lifespan
• No need for linings, coatings, catholic protection, wraps or other forms of corrosion protection
• Low maintenance costs
• Constant hydraulic characteristics over time

(almost ½ weight of metal and 1 ½ weight of concrete pipes)

• Low transport costs
• Possibility of sliding a lower sized pipe into another one provide the conditions for telescopic transportation
• No need for heavy equipment ad machinery, and ultimately lass transportation, installation and operation costs

• Fewer joints reduces installation time
• More pipes per transport vehicle

• Lower friction loss, lower pumping costs, smaller pipe diameters
• Reduction of build-up slime in the pipeline which lowers the cleaning costs
• Pipe roughness wouldn’t change during service period

• Rake coupling corrosion resistant joints with two gaskets for underground applications
• Glued coupling, bell and spigot or adapter joints with epoxy glue for above-ground applications

• Reliable and effective sealing of the joints
• Ease of joining, reduces installation time
• Flexibility of the pipeline could easily depreciate the tensions caused by heterogeneous settlement
• Possibility of exerting partial angular deviations along the line at the joints, results in the removal of low angle elbows

• Possibility of manufacturing pipes in any length and diameter based on customer’s needs
• Possibility of producing any special fittings based on customer’s request

• Lower wave celerity than other piping materials leads to lower water hammer pressures
• Better hydraulic characteristics

• Ability of tolerating axial and hoop tensions
• No need to thrust blocks
• Lower installation costs
• Ability to be installed above-ground
