Carruur Dheerka DN80 | Qof Kasta iyo Carruur Ka Baxay

Ductile iron pipe kalena DN80 (dhexeeyada asal 80mm) waxaa jiro koonfur carruurta ah ee ka mid ah carruurtii dhaqanka, carruurtii kuwa qarsoonka ah iyo carruurtii fluidka sanadka. Ugu yaraan ductile iron (ISO 2531, EN 545), wuxuu ka soo jeeda xiriirka ugu dhexeeya (> =420 MPa) oo dhammaadka (> =10%), si aysan uga baabbiyay macluumaad iyo sharciyaalada termali. Dheeriyada carruurtiisa waa lagu sameeyay PN10 hadda PN40, ee ku yidhi in ay ku sameeyeen carruurda la xirgooyinayo iyo sanadka. Waxaa lagu sameeyay cement Portland (ISO 4179) carruurta dhexdeeda si uu u caddeyn doontaa iyo uga baabbiyay, markaasaa coatingka zinc carruurta dhexdeeda (≥130g/m²) ugu yaraan u caddeyn doonaa carruurta soil. Sistamada joogga waxaa lagu sameeyay fitkiinta rubber ring si uu ugu yaraysa joogaha, ama flanged connections carruurta jooga ee ku yidhi in ay ku sameeyeen sisteeda jooga ee kuwa caafimaadka ah. Fursadaha carruurta over steel ama PVC waxaa lagu sameeyay ugu dhexeeya resistance ee sandpaper (ku yaal carruurta sandy water), carruur guud (50+ sanad), iyo maintenance kala duwan. Xaqiijinta carruurta waxaa lagu sameeyay bedding ee dhammaad ah (sand ama gravel) si aysan uga baabbiyay loads iyo deflection ee muhiim ah (up to 3° per joint) si aysan uga baabbiyay ground movement. Carruurka DN80 waxaa lagu sameeyay inuu ugu yareen branch lines iyo distribution networks kale, markaasaa compatibility carruurta ee fittings (elbows, tees, reducers) si aysan uga baabbiyay flexibility.
