Pre-insulated Pipe Fittings

Pre-insulated Pipe Fittings connect changes of direction and branches within insulated plastic piping systems. The available information supports PP-R connections and insulation calculations but does not describe a separate range of factory-pre-insulated fittings.

An insulated fitting must match the material, dimensions and joining method of the piping system. PP-R and PP-RCT use homogeneous joints made by thermal fusion. Required insulation thickness can be calculated as a project parameter together with pipe diameter and expansion.

The supported system context includes heating and chilled-water installations, cooling and air-conditioning systems, heat pumps, heat sources, swimming pools, geothermal applications and data centres. Aquatherm Blue provides PP-R pipes and matching fittings for these uses.

Match the fitting to the PP-R or PP-RCT system, diameter and SDR class. Then determine the joining method, expansion and calculated insulation thickness. Confirm project-specifically how insulation continues around the fitting because no product construction or dimensions are specified.

Supported attributes are PP-R or PP-RCT base material, diameter, SDR 7.4, 9, 11 or 17.6, thermal fusion, expansion and calculated insulation thickness.

Frequently asked questions

Determine insulation thickness as part of the system calculation. ERIKS uses calculation programs for insulation thickness, pipe diameter and expansion. Match the result to the piping material, temperature and project parameters.

Join PP-R fittings by thermal fusion according to the system dimensions. Aquatherm Blue uses socket fusion from 20 to 125 mm and butt welding from 160 mm. Then define the continuation of the insulation for the specific project.
