amapayipi e-SML, okokufakafuthi amasistimu okuhlanganisa ayakhiqizwa futhi ahlolwe ngokuya nge-EN 877. Amapayipi e-SML asikwa abe ngobude obudingekayo ngokuqondile kubasebenzi abasebenza ngempahla.Amapayipi nokufakwa kuhlanganiswe nezinsimbi zamapayipi ezifanele.Amapayipi avundlile kufanele aboshwe ngokwanele kuwo wonke amajika namagatsha.Amapayipi aphansi kufanele aboshelwe ebangeni eliphakeme elingu-2 m.Emabhilidini anezitezi ezi-5 noma ngaphezulu, amapayipi aphansi e-DN 100 noma ngaphezulu kufanele avikelwe ekuzikeni ngokusekelwa kombhobho ophuma phansi.Ukwengeza, ezakhiweni eziphakeme uxhaso lombhobho ophansi kufanele lufakwe kuzo zonke izitezi zesihlanu ezilandelayo.Amapayipi okudonsa amanzi ahlelwe njengemigqa yokugeleza kwamandla adonsela phansi engacindezelwe.Kodwa-ke, lokhu akubandakanyi ipayipi ukuba libe ngaphansi kwengcindezi uma izimo ezithile zokusebenza zenzeka.Njengoba amapayipi okukhipha amanzi kanye nokukhipha umoya engaphansi kokuxhumana okungase kube khona phakathi kwamapayipi nendawo ezungezile, kufanele angavuzi unomphela ngokumelene nokucindezela kwangaphakathi nangaphandle okuphakathi kuka-0 no-0.5 bar.Ukuze kugcinwe lokhu kucindezela, lezo zingxenye zamapayipi ezingaphansi kokunyakaza kwe-longitudinal kufanele zifakwe eduze kwe-axis ye-longitudinal, zisekelwe ngendlela efanele futhi zivikeleke.Lolu hlobo lokulinganisa kufanele lusetshenziswe noma nini lapho ukucindezela kwangaphakathi okungaphezu kuka-0.5 bar kungase kuphakame emapayipini okukhipha amanzi, njengalezi zimo ezilandelayo:
- Amapayipi amanzi emvula
- Amapayipi endaweni engemuva kwamanzi
- Amapayipi amanzi angcolile adlula ngaphezulu kwegumbi elingaphansi kweyodwa ngaphandle kokukhipha okunye
- Amapayipi okucindezela kumaphampu amanzi angcolile.
Amapayipi angaxhunywanga angaphansi kwengcindezi engenzeka yangaphakathi noma umfutho okhulayo ngesikhathi sokusebenza.Lawa mapayipi kufanele ahlinzekwe ngendlela efanele, ngaphezu kwakho konke lapho ejika khona, ukuze kuvikelwe izimbazo ekushibilikeni nasekuhlukaneni.Ukumelana okudingekile kwepayipi kanye nokuxhumana okufanelekile kumandla we-longitudinal kufinyelelwa ngokufaka izinsimbi ezengeziwe (umthwalo wengcindezi yangaphakathi kuze kufike ku-10 bar kungenzeka) emalungeni.Ulwazi olwengeziwe ngezindaba zobuchwepheshe lungatholakala encwajaneni yethu ukuze uthole ukucaciswa kwezobuchwepheshe kanye nemininingwane.
