• PVC-U (Unplasticised polyvinyl chloride) is one of the most popular thermoplastic
  materials used for pressure pipework installations. Light in weight PVC-U has excellent resistance “to chemicals and abrasion, is tasteless and odourless making it ideal for use with “potable water systems and most food products as its extremely smooth bore gives excellent flow characteristics without sediment or deposit.
  “PVC-U is resistant to most solutions of acids, alkalis, salts and solvents.”
  Connections can be made by either solvent cement or BSP threaded fittings.
  “PVC-U systems are light, strong and simple to fit using a solvent cement.”
  PVC-U is approved by the Water Research Advisory Scheme (WRAS) for use with potable water.
  PVC-U is suitable for temperatures of 0 deg C to 60 degrees C.
  PVC-U Products are clearly identified by their dark grey colour.

  WRAS Approval
  PVC-U is approved by the Water Research Advisory Scheme (WRAS) for use with potable water.

  Standards
  PVC-U pipe is manufactured in accordance with EN1452-2
  PVC-U fittings are manufactured in accordance with EN1452-3 and ISO161/1

  Chemical Resistance
  PVC-U has chemical resistance properties which are excellent being resistant to most solutions of salts, acids, alkalis and water soluble solvents. These products are NOT resistant to aromatic or chlorinated hydrocarbons.

  PVC-U 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-U 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-U pipework systems.

  	20 Degrees Celcius	30 Degrees Celcius	40 Degrees Celcius	50 Degrees Celcius	60 Degrees Celcius
  PN4	4.0 BAR	3.2 BAR	2.3 BAR	1.5 BAR	0.8 BAR
  PN6	6.0 BAR	4.8 BAR	3.4 BAR	2.3 BAR	1.3 BAR
  PN10	10.0 BAR	8.0 BAR	5.8 BAR	3.9 BAR	2.2 BAR
