Gas tube Palatech

galvanised steelpolyethylene (PE)sanitary

Specification Definition
Spiral composite pipes made of polyethylene and galvanized steel, produced according to UNI 11434 standard, suitable for creating tunnels or ducts for housing technological networks [electricity, telephony, data network, optical fiber, etc.] and/or services and sub-services [water supply, storm and sanitary sewers, technical gases, etc.]. The structured wall profile of the spiral type, obtained by helical winding, smooth internally with external ribs reinforced by an integral and continuous galvanized steel sheet, shaped like an omega, class DX51 D + ZF/Z compliant with UNI EN 10346, incorporated into the pipe wall. Continuous coupling of the steel core to the polyethylene walls achieved through chemical fastening ensuring polyethylene-steel solidarity and their perfect and uninterrupted adhesion. The dimensions allow inspection and maintenance, both ordinary and extraordinary, without tampering with the road surface.
