Insulated Pipe – High Temp
Our High Temp multilayer insulated pipe is imported from EMMETI in Italy and is specifically designed for Heating Systems in mind, although it is also ideal for Hot Water domestic applications. This pipe has undergone an additional manufacturing step of cross linking the molecules of the inner and outer layer of polyethylene. Thanks to this process it has a higher temperature resistivity of 95 degrees continuous temperature and a peak of 110 degrees for a short period (note that locally available pipe is only suitable for up to 70 degrees). This High Temperature pipe is therefore ideal for Central Heating installations with radiators as well as domestic hot water applications. The pre-installed layer of insulation (various thicknesses available) makes the pipe easy to install and also it minimises heat losses. When using in domestic hot water applications, the hot water inside the pipe remains warm for much longer versus running a non-insulated pipe straight in the wall (as is the common practice in South Africa)
