To use ppr pipe for under floor heating pipe, must choice the chrome plated or nickel plated brass fitting

Those buried in the floor tiles and cement following the wrong track complex piping and valves, in the end how much can withstand the temperature and how much pressure test? Geothermal, as buried "hidden work" would lead to doubts about a lot of people, although people are trying through various channels to understand, learn knowledge about geothermal, it is often not too successful. Select manifolds
Real life is about 6 years
However, this data is only theoretical and do not take into account regional differences in water quality in the specific situation. "A geothermal practitioners told reporters inside the convention, the current industry standard is manifold life of between 6 to 8 years. Geothermal heating system in the life of each valve within the valve body also decided to use the material in its Although at this stage in accordance with national standards should be used for 10 years, but were copper, steel, plastic and other materials made of body, life certainly different. "Under normal circumstances, as an open secret within the industry, including minutes, including some of the geothermal water valve, the actual life around in six years. "
Water Separator Selection
Manifold role of material used to choose life
By function can be divided into manual-based and intelligent manifold (1) influent flow distribution as necessary to ensure the flow of the regional branch of the loop to meet the heating load requirements. Meanwhile, the branch return water main pipe water flow together to achieve cycle run. (2) connected to the kinetic energy of various pieces of control (manual control valve, built-in valve, electric valves, flow meters, etc.), easy to implement building multi-region (room) the branch loop regulation and control of heating demand.
Press material can be divided into copper manifold, PPR water separator, stainless steel water separator, and aluminum manifolds.
According to the selected floor heating pipe (PE-Xa, PE-RT, PPR) and sub-catchment devices connected to the chemical corrosion of the copper is different to distinguish between use. Elected to use the PE-X series tube, the above three sub-catchment devices can be used. Elected to use PPR pipe PE-RT or when to do to warm, you must use nickel or chrome plated copper sub-catchment devices.
First, sub-catchment should be noted that the thickness of the wall for main bars and compressive strength;
Second, should pay attention to the content of copper in copper whether the relevant national standards;
Third, care should be connected with the main bar inside the spool valve material (copper, iron or plastic);
Fourth, we should pay attention to its anti-corrosion and anti-oxidation performance.
Internal and external surfaces shall be clean, no cracks, blisters, cold shut, slag, defects such as uneven. Surface plating of the connector color should be uniform, firm coating, not plating defects are off. The total catchment into sub-device, outlet pipe diameter is generally not less than 25mm ,5-10 years
