I-SML no-hub cast iron drainage pipes and fittings meet the standard of BSEN877, DIN19522, ISO6594.Iimathiriyeli ziyi-100% ezinokuphinda zisetyenziswe kwaye zisetyenziswe, kunye nokuhanjiswa kwesandi esisezantsi, ubungqina bomlilo, ubungqina bokuvuza kunye nokuchasana nokuhlwa.Zisetyenziswa ngokubanzi ukukhutshwa kwamanzi kwizakhiwo, i-drainage, inkunkuma kunye ne-vent.Kwakhona inkqubo yamanzi emvula efakwe ngaphandle kwezakhiwo kunye nenkqubo engcwatywe phantsi komhlaba inokubonelelwa.
Imibhobho ye-EN877 ngaphandle ibomvu, i-epoxy enobunzima obungekho ngaphantsi kwe-70um.Ngaphakathi kukho iresin epoxy etyheli enobunzima obuyi-120um.Okanye ngaphakathi nangaphandle kungaphezulu kwe-120μm yomgubo we-epoxy yokwambathisa ngombala obomvu.
Izixhobo zibomvu ngaphakathi nangaphandle, intlaka ye-epoxy engamanzi ingaphezulu kwe-70um, kwaye umgubo we-epoxy ungaphezulu kwe-120um ubukhulu.
