Corrosion resistance
Escalating deterioration of water pipelines due to corrosion in old iron pipes threatens our ability to provide safe drinking water and is a complicated and costly problem across many regions of the world, including pakistan.
Pvc pipes are invulnerable to underground external corrosion as well as internal pipe corrosion. So while certain pipe manufacturers continue to explore “solutions” to corrosion – because their materials are affected by it - pvc remains indisputably resistant to it.
Chemical resistance
Pvc pipes exhibit excellent resistance to a wide range of chemical reagents and disinfectant chemicals.
With low risk of materials eating through the pipe, pvc pipes are highly suitable for most water infrastructure projects as they can convey most strong acids, alkalis and aqueous solutions (except those which are strongly oxidising), aliphatic hydrocarbons, fluorides, photographic and plating solutions, brine, mineral oils, fats and alcohols.
Reduced failures and blockages in wastewater pipelines
A major concern within any pipeline system is pipe blockages, a costly and complicated problem that can cause untold damage and hours of repairs. Slow flowing water through a pipeline creates more opportunity for potential blockages and failures in a system with many connections. The extremely smooth lining of pvc pipe - when compared to a copper, clay or concrete pipe - reduces water flow resistance and ensures that water reaches its intended destination with proper pressure. Pvc piping allows water to flow freely and maximizes water pressure. The increase flow of pvc pipes also prevents build up in sewage and waste water systems.
Smooth bore allows high flow rates for water transfer
Pvc pipes should be considered for water supply pipeline projects because they outperform alternative materials in performance and cost effectiveness. Their smooth bore allows high flow rates, reducing the potential for blockage and failures. Pvc pipes have a proven track record of excellent long-term performance and offer extended, trouble free service life.
Leak free joints
Pvc pipe’s ultra-smooth surface reduces pumping costs and its leak-free joints eliminate water loss – which can be up to 40 per cent in some old-technology and corrosion-prone piping networks. Elastomeric seals allow pvc pipes to be quickly and easily joined, without the need for electricity or protection from the weather.
Lower cost
Pvc pipes offer significant cost savings for projects, even more so when installation, low breakage rates and life cycle costs are taken into consideration. The longevity of pvc pipes also means the pipes function more efficiently, reducing maintenance and ongoing work to the pipe making it more affordable over time.
Pvc pipes - best pipeline choice for pipe under load
Pvc pipes are extremely flexible and can flex without breaking when loaded externally from soil weight and heavy duty traffic. Rigid pipes, such as those made of concrete, clay or ceramic are unable to flex when loaded and will experience wall crushing and collapse when their load limit is reached.
Tree root intrusion resistance
Some pipe materials are more resistant to root intrusion than others. Pvc pipe is more resistant to root intrusion because it has fewer joints. Because of their flexibility, the tightly fitting pvc joints are less likely to leak as a result of settlement of backfill around the pipe. Vitrified clay pipe is easily penetrated and damaged by tree roots. Concrete pipes also allow root intrusions to a lesser extent than vitrified clay pipe.
The details are very much informative. Good and keep it up.
