PEX tubing for noobies

As a result of this work was developed normative and technical documentation for hire and pipes increased corrosion resistance in relation to the conditions of heating systems and developed their production. Rolled JSC “Severstal” in OAO “Vyksa” possible to produce longitudinal electric-welded pipes, OJSC “Volga Pipe Plant” spiral pipes increased resistance against localized corrosion of PEX system heating systems according to technical specifications TU 14-3R-70-2003 and TU 14-3P-71-2003 “Plastic electric-welded high resistance to localized corrosion of PEX system heating systems” in diameter 530-1200 mm and 114-53 mm and TU 14-3R-69-2003 “Plastic electric spirally enhanced resistance to local corrosion of PEX systems of heating networks, “respectively. These specifications are designed to pipe together with JSC “USAn Thermal Engineering Institute,” and agreed with Gosgortechnadzor RF. These specifications are stipulated purity on Canvas: Canvas density should be no more than 2 inclusions in 1 mm2 area microsection, and the pipes to be supplied to these specifications, must be resistant against local corrosion.
