Carruur K9 Ductile | Xaqiijiyaha Ilaahyada & Ugu muuqata korosion

Dhulka K9 waxaa la sameeyaa dhammaan jidadka ee ku yaray mid ka ah ee ku jiray in ay ku qeexdo xiriiraha mekanikal, wuxuu u dirir kartaa oo ku yaray dhibaatooyinka dhulka. Isagu "K9" waa labadaas oo ku jiray standardyada Eropiyed, oo ku yaray degmada ee ku jiray gacanta ≥480 MPa, gacanta ≥370 MPa, iyo isbedelka ≥7%, oo ku samayn doontaa gacanta iyo isbedelka. Dhexeeyaas waa graphite spheroidal, oo ku yaray kala duwanayo stress concentration karaa graphite flake ee dhulka cast iron, oo ku yaray hantiwinta badbaadka iyo ku caddeysa badbaadka. Wuxuuna u talagalay via casting centrifugal, oo dhulka K9 waa la mid ah wall thickness uniform iyo defects casting kale kooda, si aad ugu yaraysid matrix iyo ku yaraysid toughness annealing. Xogga anti-corrosion, macaamiisha hot dip galvanizing ama polyurethane coating, waa lacag lagu qaadi doonaa soil iyo water corrosion, waxaan ku yaraysaa zinc coating protection anode sacrificed. Cement mortar ama epoxy resin linings waa lagu soo baxdayaa lacagta carruurta iyo ku caddeysa scaling internal. Dhulka K9 waa ka mid ah carruurtaanka water supply, gas transmission, iyo industrial pipelines, sababtoo ah gacanta uu ku yaray (working pressure ≥1.0 MPa) iyo seismic performance. Joint designs flexible waa ka mid ah angular deflection iyo axial displacement, oo ku yaray adiga ground movement. Standardized dimensions iyo installation methods waa ka mid ah simplification construction, iyo service life koonfurta (50+ years) oo ku yaray maintenance costs. Degmada K9 waa ka mid ah projects ee ay ku sameyn doonaa medium to high pressure, sababtoo ah water supply building tall iyo long distance water transmission, iyo waa ka mid ah regions ee ay ku sameyn doonaa standards Eropiyed, oo ku yaray choice preferred engineering projects international.
