FAQ's
Where can I use CPVC?
CPVC fire sprinkler pipes and fittings can only be used for wet pipe systems. They are not designed for use in systems using compressed air or gases.
The system is listed by the Loss Prevention Council, Underwriters Laboratories, Factory Mutual and Lloyds Registry for a wide variety of applications includingLight Hazard and OH 1 applications, subject to agreement between the manufacturer, the purchaser, the authority having jurisdiction and/or the insurer. The CPVC Fire Sprinkler System is specified as a suitable piping material in BS9251 - Sprinkler System for Residential and Domestic Occupancies and as part of the Automatic Fire Sprinkler Rules - Technical Bulletin 227 - Pipework.
It is ideal for use in houses and apartments - including high rise developments, hotels, shops, schools, libraries, residential homes, hospitals, offices, historic buildings and museums, as well as in offshore accommodation modules.
Does it need special handling?
CPVC pipes and fittings are lightweight and do not need the special handling equipment required for steel. They are tough and corrosion resistant, but should not be carelessly dropped or have heavy objects dropped on them. If improper pipe handling results in scratches, splits or gouges, the damaged section will need to be cut out and disregarded.
In storage, CPVC pipe is best covered to prevent dirt contamination, and fittings should be kept in their original boxes until required for use. If kept outdoors, the pipe should be protected from the elements and from direct sunlight.
What is the safe working pressure?
The system will operate safely at pressures of up to 12 bar. The recommended pressure test is 1 1/2 times working pressure for 2 hours or 15 bar for 2 hours.
How is the system joined?
The cold solvent cement welding process is at the heart of the CPVC system and is the principal method used for joining CPVC pipes and fittings. The system is foolproof, provided that the joints are properly constructed.
The CPVC Fire Sprinkler System should only be installed by suitably qualified installers - see below.
How do I connect to other materials?
Both Male and Female NPT and BSP threaded adaptors are available. The range offers brass threaded male or female fittings, complete with a stainless steel outer reinforcing rings which provide heavy-duty connectors to threaded components such as valves or pumps. Flanges are available, drilled to ASA 150, and a grooved coupling adaptor will connect to flexible groove joint couplings such as Victaulic Type 75.
What range is available?
