Kobunjiniyela bokuphakelwa kwamanzi kanye nokukhipha amanzi, amanethiwekhi amapayipi kamasipala, kanye nezinhlelo zamapayipi ezimboni,ipayipi lensimbi elithambilesekuyindlela efanelekile yokufaka esikhundleni samapayipi ensimbi ensimbi esetshenziswayo kanye nensimbi ngenxa yezakhiwo zayo ezinhle kakhulu zomshini kanye nokumelana nokugqwala. Ukuqonda imingcele ebalulekile yobuchwepheshe yamapayipi ensimbi athambile kubalulekile kubaklami, abathengi, kanye nezinkampani zokwakha, kungakhathaliseki ukuthi zingomthombo wamanzi noma ukuthuthwa kwendle. Lesi sihloko sizoxoxaIpayipi lensimbi elithambile le-DINSENnjengesibonelo sokuchaza ngokuhlelekile imininingwane yayo, isisindo, ingcindezi yokusebenza, kanye nezici zokumboza.
I. Imininingwane kanye nobukhulu bepayipi lensimbi elihlanganisiwe: Ungayithola Kanjani Imodeli?
Uma ukhetha amapayipi, kubalulekile kuqala ukucacisa ubukhulu kanye nobukhulu bamapayipi ensimbi athambile. Izindinganiso zomhlaba wonke zisekelwe kakhulu ku-ISO 2531 noma ku-EN 545, ezihlukaniswe ngobubanzi obujwayelekile (DN).
Uma sibheka ipayipi lensimbi elithambile le-DINSEN njengesibonelo, amapayipi e-K9 grade (izinga lobukhulu bodonga elijwayelekile) avame ukusetshenziswa, anobubanzi obujwayelekile obuqala ku-DN80 kuya ku-DN2000. Nazi ezinye zezinhlobo zamapayipi ezivamile:
- DN80: Ububanzi bangaphandle buyi-98mm, ubukhulu bodonga buyi-6.0mm
- DN100: Ububanzi bangaphandle buyi-118mm, ubukhulu bodonga buyi-6.0mm
- DN200: Ububanzi bangaphandle bungu-222mm, ubukhulu bodonga bungu-6.3mm
- DN400: Ububanzi bangaphandle bungu-429mm, ubukhulu bodonga bungu-8.1mm
- DN1000: Ububanzi bangaphandle 1048mm, ukujiya kodonga 13.5mm
Amazinga ahlukene obukhulu bodonga (K8, K9, K10, K12) azothinta amandla okuthwala ingcindezi kanye nesisindo seyunithi yepayipi.Abasebenzisi bangakhetha ngokufanele ngokuya ngengcindezi yomklamo.
II. Isisindo ngemitha ngayinye yepayipi lensimbi elithambile: Lingakanani ipayipi lensimbi elithambile elithambile?
Umbuzo ovamile ekuthengweni kobunjiniyela uthi: Isisindo sepayipi lensimbi elithambile singakanani? Isisindo sepayipi lensimbi elithambile sakhiwa isisindo somzimba wepayipi kanye nesisindo sesokhethi, okuthinta ngqo izindleko zokuhamba, ukuphakamisa, kanye nokufaka.
Uma sithatha ipayipi lensimbi elithambile le-DINSEN K9 (ubude obujwayelekile obungamamitha ayi-6) njengesibonelo, isisindo sethiyori simi kanje:
- I-DN100: Cishe 15.1 kg/m → 95 kg ngepayipi ngalinye
- I-DN200: Cishe 30.6 kg/m → 194 kg ngepayipi ngalinye
- I-DN300: Cishe 50.8 kg/m → 323 kg ngepayipi ngalinye
- I-DN500: Cishe 104.3 kg/m → 669 kg ngepayipi ngalinye
- I-DN800: Cishe 215.2 kg/m → 1394 kg ngepayipi ngalinye
Isisindo sangempela singase sihluke kancane ngenxa yezici ezifana nobukhulu be-zinc coating kanye nolwelwesi lwangaphakathi lwesimende. I-DINSEN inganikeza amaphepha okubala isisindo anembile okuhlelwa kwesabelomali sephrojekthi kanye nokuhlela izinto.
III. Ukucindezela Kokusebenza Kwepayipi Lensimbi Elihlanganisiwe
Ipayipi lensimbi elithambile linamandla aphezulu okubamba kanye namandla okucindezela ajikelezayo. Ipayipi lensimbi elithambile elithambile elijwayelekile le-K9 livame ukuba nomfutho wokusebenza ongu-16 bar (1.6 MPa), kuyilapho amazinga aphezulu okujiya kodonga (njenge-K12) afaneleka ukusetshenziswa komfutho ongu-25 bar noma ngisho no-40 bar.
Amapayipi ensimbi e-DINSEN akhiqizwa ngokuqinile ngokwezindinganiso ze-ISO 2531. Ipayipi ngalinye lihlolwa nge-hydrostatic ngaphambi kokushiya ifektri ukuqinisekisa ukuphepha okuphezulu ngokuphindwe ka-1.5 kunomfutho wokusebenza womklamo, okwenza afaneleke kakhulu ekudlulisweni kwamanzi akude, amapayipi okuphakamisa isiteshi sokupompa, kanye namapayipi ezimboni anomfutho ophezulu.
IV. Isimbozo seZinc Sokuvikela Ukugqwala
Indima Yokumbozwa Kwezinki Emapayipini Ensimbi E-Ductile Enye yezindlela ezibaluleke kakhulu zokuvikela amapayipi agqitshiwe ukumbozwa kwezinki emapayipini ensimbi e-ductile. Ukumbozwa kwezinki akugcini nje ngokuhlinzeka ngokuvikelwa kwe-cathodic kodwa futhi kwakha uhlelo oluhlanganisiwe lokulwa nokugqwala ngopende wangaphandle noma i-polyethylene sheathing.
Amapayipi ensimbi e-DINSEN ahambisana ne-zinc coating engu-≥200 g/m² (ngokusho kwe-ISO 8179 standard), embozwe nge-asphalt ebomvu ye-epoxy noma i-polyurethane finishing layer, okuthuthukisa kakhulu ukumelana nokugqwala kanye nokuphila isikhathi eside. Enhlabathini egqwalisayo noma ezindaweni ezimelana nokumelana okuphezulu, kukhona i-zinc coating eyengeziwe + ifilimu ye-PE noma i-polyurethane coating ephelele, enempilo yenkonzo eklanyelwe iminyaka engu-50-100.
V. Kungani Kufanele Ukhethe Amapayipi Ensimbi E-DINSEN Ductile?
Njengomhlinzeki wamapayipi ensimbi acwebezelayo ochwepheshe, i-DINSEN inikeza uhla oluphelele lwezincazelo kusukela ku-DN80 kuya ku-DN2000, isekela ubukhulu obuhlukene bodonga njenge-K8, K9, K10, kanye ne-K12, futhi ingenza ngezifiso ubude, ama-lining angaphakathi (udaka lukasimende/i-epoxy resin), kanye nezixazululo zokuvikela ukugqwala kwangaphandle ukuze kuhlangatshezwane nezidingo zamakhasimende.
Wonke amapayipi e-iron ductile aqinisekiswe yi-ISO 2531 / EN 545. Amathebula aphelele esisindo, ubukhulu, ingcindezi yokusebenza, kanye nemingcele yokumboza i-zinc ayatholakala. Kusekelwa ukupakisha kwamanye amazwe kanye nezinsizakalo zokuhambisa ezifika kanye.
Ukuze uthole amatafula okukhetha noma amathuluzi okubala isisindo anemininingwane eminingi, sicela uvakashele i-I-DINSENnoma xhumana nethimba lokuthengisa lobuchwepheshe ngqo.
