Sliding pipe supports are used in a variety of applications, including above-ground piping and piping in buildings, tunnels, and trenches. They can be designed for high-temperature, cold-temperature, and even dual-temperature applications. High temperature pre-insulated supports utilize structural inserts within the support for load carrying and clamping capabilities. Low-temperature supports use various materials and densities to carry the load of the pipe.
For different use, Kaff Rees insulated Pipe Support System includes the following forms
1. Sliding Pipe support system;
2. Guide pipe support system (including guide support for vertical pipe);
3. Limit / fixing pipe support system;
4. Bearer supporting bracket system.
General structure of insulated pipe support system(Sliding system)

⑩ Nut
Kaff Rees offers a complete product range of insulated cryogenic pipe supports for all kinds of low temperature pipe systems. The insulated pipe supports are designed to be clamped mechanically to the piping by means of disc spring bolting. The pipe support cradle, which houses the HD-PIR insulation, is made of steel and is hot-dip galvanised as standard.
Cryogenic pipe supports by Kaff Rees are standardised and designed according to recognised international technical regulations and standards. They comprise a pipe diameter range from OD 21.3 mm / 0.84 in to OD 965.20 mm / 38 in with insulation thicknesses from 25 mm / 0.98 in to 250 mm / 9.84 in. The supports are made from materials suitable for the specified loads and temperatures (temperature of medium to -196 °C).
HDPIR
HDPIR is a kind of foaming polymer, with the features of plastic, rubber and cork. The raw materials are isocyanate, polyether, foaming agent, catalyst, flame retardant, etc. After high speed stirring, materials react and foam to cellular structure product, composed of millions of tiny and uniform sealed cells. It provide benefits of low density, low thermal conductivity, low water absorption. The performance is better than timber.
