The Science Behind Quality Control in Industrial Piping
Demonstrating system design compliance using industry leading thermoplastic technology in the desalination process
In recent blogs, we have discussed many of the technical and functional benefits of using Corzan® CPVC Piping Systems in desalination.
However, as desalination becomes increasingly instrumental in protecting growing populations worldwide, compliance has never been more stringent in this challenging industry.
Corzan CPVC Piping Systems are fully compliant with a wealth of internationally recognised standards of quality functionality and safety.
As a CPVC material, its suitability for desalination is illustrated by its compliance to ASTM standards and its chemical resistance and pressure bearing capabilities are demonstrated in its compliance to many internationally recognised ISO standards.
Let's take a look at some of the international standards and agencies that recognise Corzan CPVC Piping Systems as the designers choice for developing safe efficient desalination facilities, for the future of our global water supply.
(For a full list of Corzan CPVC Piping Systems listings by ASTM, ASME, NSF, ISO and more, access our free Desalination CPD slideshow here.)
Corzan CPVC Piping Systems offers system designers a number of installation advantages, particularly when assembling desalination infrastructure.
CPVC is approximately 1/8th the weight of comparable sized steel. It is a lightweight construction material that saves time and energy during installation. It is also easier to cut, allowing for safe on-site fabrication with no requirement for heat sources, including open flames.
Its suitability for working practices in industrial applications are illustrated by its compliance under many international standards set out by ASTM, including the following:
- ASTM D2855, Standard Practice for Making Solvent Cemented Joints and Poly(Vinyl Chloride) (PVC) Pipe and Fittings
- ASTM F402, Standard Practice for Safe Handling of Solvent Cements, Primers and Cleaners used for joining thermoplastic pipe and fittings
- ASTM F656, Standard Specification for Primers for use in Solvent Cements joints in PolyVinyl Chloride (PVC) Plastic Pipe and Fittings
Corzan CPVC Piping Systems are certified as safe for potable water applications in that it does not leach harmful levels of potential contaminants, throughout its service life.
This is illustrated by its NSF 61 certification for Drinking Water System Components, among many others:
- NSF Standard 61, Drinking Water System Components - Health Effects
- NSF Standard 14, Plastic Piping Components and Related Materials
Corzan CPVC Piping Systems possess exceptional resistance to a wide range of corrosive substances including ferric chloride, sulfuric acid and sodium bisulfite.
It is specifically designed for chemical resistance in the desalination process, as demonstrated by the following standards:
- ISO 4433-3 Thermoplastics pipes — Resistance to liquid chemicals — Classification — Part 3: Unplasticized poly(vinyl chloride) (PVC-U), high-impact poly (vinyl chloride) (PVC-HI) and chlorinated poly (vinyl chloride) (PVC-C) pipes
- ISO/TR 10358, Plastics pipes and fittings — Combined chemical-resistance classification table
Corzan CPVC Piping Systems are safe and dependable in high pressure and temperature conditions, even in hot climates with high ambient temperatures and UV exposure.
Its inherent heat resistance has earned its reputation in desalination applications, as demonstrated by the following ISO certification:
- ISO 15877-2:2009, Plastics piping systems for hot and cold water installations — Chlorinated poly(vinyl chloride) (PVC-C)
