Carbon Steel Instalpress System
The Carbon Steel Instalpress system’s tube is an E-220 non-alloy steel precision tube with material no. 1.0038, fine wall and welded lengthwise as stated in the DIN EN 10305-3 standard. Non-alloy steel is characterised by its high grade of purity and low carbon content. The tube is galvanised on the outside (heating) or inside/outside (fire protection) and the welding is polished in order to guarantee a perfectly sealed surface. The Carbon Steel Instalpress tubes are supplied in 6-meter bars (EN 10217 and DVGW GW 541). The internal and external surfaces are pure metal, and are therefore free from tempering colours, are shiny and are also free from corrosive or hygienically harmful substances. All the system’s tubes are tested and certified by DVGW. The series 1 tubes are supplied in 5 meter bars. The series 2 tubes are supplied in 6 meter bars.
The Carbon Steel Instalpress accessories are made from E-235 +N non-alloy steel, material no. 1.0308 according to DIN EN 1305-2 and supplied in 12 mm to 108 mm dimensions. The galvanised zinc layer protects the accessory from external corrosion. The accessories are permanently marked with the manufacturer’s logo and the inscription “Zinc Plated”. The Carbon Steel Instalpress accessories are supplied with EPDM O-rings.
