Pipes and Fittings in this section are all British Standard. This standard is based on the Nominal Bore of the pipes across the full range and not the diameter. For clarification please see the table in each pipe class in the drop down marked [+] More Information. If in doubt please ring us to avoid ordering the wrong pipework.

PVC Pipe System Key Facts:

1.	Temperature range 5°C to +60°C
2.	Wide range of chemical resistance (check below what is not resistant)
3.	PVC Pipe is lightweight and extremely easy to install
4.	Smooth bore resists lime scale build-up and gives superior flow
5.	Design life of 50 years based on max pressure @ 20°C
6.	Abrasion resistant and corrosion free
7.	Precision Matched PVC Pipe System
8.	Non toxic suitable for potable water
9.	Ideal for Acids, alkalis, chemical processing, effluents and effluent treatment
10.	Material cost (43%) labour install cost (60%) savings over metal pipe systems

 

PVC Material:

Pipestock PVC pipework is only manufactured from the very best grade A raw material. PVCu is the acronym for Polyvinyl Chloride - unplasticised which is a thermoplastic material specially formulated for the manufacture of PVCu Pipe, PVCu Pipe Fittings and PVCu Valves. This material ensures that the PVC pipe system contains the necessary performance characteristics for tough industrial applications.
 

About PVC Pipework:

PVC is an excellent thermoplastic pipe system used in many industries for the transportation of liquids including those containing: acids, alkalis, chemical processing, sewerage and water treatment. PVC is extremely resistant to chemicals and is non-toxic. These systems are light, strong and very easy to fit using PVCu Solvent Cement. PVCu Products are easy to identify due to their dark grey colour.
 

WRAS Approvals & Standards:

PVC is approved by the Water Research Advisory Scheme (WRAS) for use with potable water.
PVC Pipes are manufactured in accordance with BS3505 and EN1452-2
PVC Pipe Fittings are manufactured in accordance with BS4346 Part 1
PVC Pipe Fittings Threaded conform to the requirements of BS 21 / DIN 2999 / ISO 7
 

PVC Pipe System Chemical Resistance:

uPVC has been proven to be resistant to a wide range of diluted acids, alkalis, salts  and water soluble solvents. uPVC is not resistant to aromatic or chlorinated hydrocarbons. For more detailed information on specific chemical resistance for uPVC please ring us on 0845 634 1053 (local rate).
 

PVC Pipe System Pressure/Temperature Relationship:

Pressure ratings for plastic pipework systems are always quoted at 20°C, it is a fundamental principle of such systems that if the temperature is increased then the pressure rating must be reduced. PVC systems should never be used for temperatures in excess of 60°C. The following chart gives a rough guide as to the temperature/pressure relationship of PVC pipework.

 

 

	20 °C	30 °C	40 °C	50 °C	60 °C
Class C	9.0 BAR	9.0 BAR	5.2 BAR	3.5 BAR	2.0 BAR
Class D	12.0 BAR	9.6 BAR	6.9 BAR	4.6 BAR	2.6 BAR
Class E	15.0 BAR	12.0 BAR	8.7 BAR	5.8 BAR	3.3 BAR
