Can alpex pipe connections be used for concealed installations or under screed?
“The alpex pipe and system connections for drinking water and heating installations are suited for concealed installations or installations under screed without any concerns. For detailed information, please refer to DIN 1988 / DIN EN 806.”
在公司资料中查看Is it necessary to insulate alpex multilayer composite pipes for cold water lines against condensation water?
“Yes, insulation of cold drinking water pipes is required according to DIN 1988-200 tab. 8 and 9 in order to prevent condensation and to protect drinking water from warming-up due to elevated ambient temperatures. Pipes that come into contact with the structure (floating, screed, etc.) must be protected with at least one layer of insulation (pipe with protective sheathing).”
在公司资料中查看Are alpex installations possible with de-mineralised water?
“No, since the installation of multilayer composite pipe systems usually includes brass fittings. Brass fittings may be affected by corrosion damage in connection with de-mineralised water (aggressive).”
