. Excellent Insulation Efficiency . Environmental Friendly: CFC, HCFC and HFC free . Fire Rating to BS476-6, BS476-7 and BS476-20 . Suitable for air-conditioning and Refrigeration Use
Pre-insulated pipes are widely used in air-conditioning and refrigeration system. They consist of a carrier pipe, normally black steel pipe ; an insulating layer and an outer casing.
The main purpose of pre-insulated pipes is to maintain the temperature of fluid inside the pipes when transporting the chilled water from the chiller plant to various location inside the building.
Advantage of using PIP System
Excellent Insulation Property The pre-insulated pipe has an excellent insulation property compared with other thermal insulation materials. • Easy Installation The pipes are pre-fabricated in the factory thus saving time and cost for on-site installation. • Environmental Friendly The insulation material used has zero ozone depleting chemicals. • Fire Safety The pre-insulated pipes together with metal jacket is rated by BS476 Part 6, BS476 Part 7 and can withstand 2 hours in BS476 Part 20, therefore no fire ring is necessary when penetrating wall and floor opening.
Pre-insulated Pipes Materials
Cladding To ensure minimum insulation thickness is achieved, the cladding material has to be specified and sized accordingly.
Standard cladding material to be used: • Galvanized Steel • Aluminium • Stainless Steel Grade 304 • Stainless Steel Grade 316
Carrier Pipe
Black steel pipe to BS EN10217-1 and BS EN10255 will normally be used as the inner carrier pipe. Alternative material such as stainless steel and copper pipes can be supplied upon request. The black steel pipes shall be supplied with plain ends / beveled end for butt welding on-site. The pipes will be delivered in standard length of 6 meters.
Insulating Layer - Polyurethane Foam
Insulation inside the pre-insulated pipes is the most important part in the system. This insulating layer prevents heat loss and gain from the carrier pipes, saves energy and improves effectiveness throughout the system.
To reduce the environmental impact, the chemicals isocyanate and polyol used to produce polyurethane foam has to be CFC free. Nowadays, the requirement has been upgraded to CFC, HCFC and HFC free.
