Izindaba - I-Ductile Iron Pipe: I-Mainstay ye-Modern Pipeline Systems

Ipayipi le-Iron Ductile, yenziwe ngensimbi eyinsimbi njengesisekelo sezinto. Ngaphambi kokuthululwa, i-magnesium noma i-magnesium yomhlaba engavamile kanye nezinye izinto ze-spheroidizing zengezwa ensimbi encibilikisiwe ukuze i-spheroidize i-graphite, bese ipayipi ikhiqizwa ngochungechunge lwezinqubo eziyinkimbinkimbi. Okuhlukile kwe-iron ductile ukuthi iningi noma yonke i-graphite encishisiwe isesimweni esiyindilinga, futhi lesi sici sesakhiwo sithuthukisa kakhulu ukusebenza kwento. Ngemuva kokukhishwa kwe-anneal, isakhiwo se-metallographic seIshubhu Lensimbi Elimnyamai-ferrite kanye nenani elincane le-pearlite, futhi izakhiwo zemishini zinhle. .

Umlando wokuthuthuka weI-Ductile Iron Tubeigcwele emisha kanye nempumelelo. Ngasekupheleni kwawo-1980 nasekuqaleni kwawo-1990, ebhekene nokuvinjwa kobuchwepheshe bokukhiqiza ipayipi lensimbi le-centrifugal langaphandle kanye nezimo ezicindezelayo zokugunyazwa kwelungelo lobunikazi, i-2672nd Factory of the Chinese People's Liberation Army (umanduleli we-Xinxing Casting Pipe) yathatha ngesibindi umsebenzi wokucwaninga nokuthuthukiswa okuzimele. Ngo-1993, ipayipi lensimbi yokuqala eyi-centrifugal ductile iron e-China laphuma ngempumelelo emgqeni wokukhiqiza, okuphawula ukuthi izwe lami selizuze igxathu elisuka ekuqaleni kulo mkhakha, futhi kwathatha iminyaka eyisishiyagalombili kuphela ukuphothula inqubo yeminyaka engama-40 yokuthuthukiswa kwamazwe aseNtshonalanga. Namuhla, i-Xinxing Casting Pipe isithuthuke yaba umkhiqizi wamapayipi ensimbi amakhulu kunawo wonke futhi enamandla kunawo wonke emhlabeni, futhi ibambe iqhaza ekwakhiweni kwezindinganiso zamapayipi asakazwa emhlabeni, ngokuqhubekayo ikhuthaza ukuthuthukiswa kwemboni yamapayipi ensimbi edonsa amanzi.

Amapayipi Ensimbi Ama-Ductile Anezici Ezihlukahlukene Zokusebenza

1. Amandla Aphezulu kanye Nokuqina Okuhle: Amapayipi ensimbi e-Ductile anamandla amakhulu, futhi amandla awo athuthukiswa kakhulu uma kuqhathaniswa namapayipi ensimbi ajwayelekile. Ngenxa yokuthi i-graphite isatshalaliswa ngendlela eyindilinga, umphumela wokuhlukanisa ku-matrix uyancishiswa, okwenza ipayipi mancane amathuba okuthi liphuke uma lingaphansi kwengcindezi enkulu nomthelela. Ngesikhathi esifanayo, inokuqina okuhle, ngobude ngokuvamile obungaphezu kuka-10%, futhi ingakwazi ukuzivumelanisa nokuncipha komhlaba, ukunyakaza komhlabathi nezinye izimo ngokwezinga elithile. Akulula ukulinyazwa ukuguqulwa, okuthuthukisa ukuthembeka kokusebenza kwenethiwekhi yamapayipi

2. Ukumelana Nokugqwala Okuqinile: Ngokusebenzisa izinqubo ezihlukahlukene zokwelashwa ezilwa nokugqwala, ezifana nopende we-asphalt, ulwelwesi lukasimende lodaka, i-epoxy coal tar coating, i-epoxy ceramic lining, i-aluminate simende enamathela, i-sulfate usimende enamathela kanye ne-polyurethane enamathela, amapayipi ensimbi e-ductile angakwazi ukumelana ngokuphumelelayo nokugqwala kusuka kumidiya ehlukene. Kungakhathaliseki ukuthi isetshenziselwa ukuthutha igesi, amanzi ampompi, noma ukuthuthwa kwendle, ingagcina ukusebenza okuzinzile ezindaweni ezihlukahlukene eziyinkimbinkimbi, inwebe impilo yesevisi yepayipi, futhi yehlise izindleko zokulungisa. .
3. Ukuvalwa Okuhle: Umlomo wepayipi wamukela isixhumi esibonakalayo esivumelana nezimo, esingakwazi ukuzivumelanisa nokugudluzwa kanye nokuguqulwa phakathi kwebanga elithile, senze umphumela wokuvala okuhle engxenyeni yokuxhuma ipayipi, futhi kuvimbele ngempumelelo ukuvuza koketshezi. Ngesikhathi esifanayo, inqubo yokukhiqiza ephezulu yokunemba kwepayipi ngokwayo iqinisekisa ukunemba okufanayo kwesokhethi, ithuthukise ngokwengeziwe ukusebenza kokuvala, futhi iqinisekise ukusebenza okuphephile kwesistimu yamapayipi. .
4. Easy Ukufakwa: Uma kuqhathaniswa namanye amapayipi, isisindo samapayipi ensimbi e-ductile silinganiselwe, futhi inqubo yokufaka ilula. I-interface yayo eguquguqukayo isiza izisebenzi zokwakha ukuthi ziqhube umsebenzi wokuxhuma, zinciphise isikhathi sokufaka kanye nokuqina komsebenzi. Endaweni yokwakha, ukufakwa kwamapayipi kungaqedwa ngokushesha ngaphandle kwemishini eyinkimbinkimbi kanye nochwepheshe abaqeqeshiwe, okunciphisa kakhulu umjikelezo wephrojekthi futhi kuthuthukise ukusebenza kahle kokwakhiwa. .
5. Ukusebenza Okuhle Kwe-Antifreeze: Ezindaweni ezibandayo, ukusebenza kwamapayipi okunqanda ukuqhwa kubalulekile. Amapayipi ensimbi ane-ductile anezinga elithile le-antifreeze. Uma nje kungeyona indawo enokhahlo ngokwedlulele, ngeke kube khona imifantu ebanda kakhulu kanye nokuqhuma. Lokhu kuyenza isetshenziswe kabanzi ekuhlinzekweni kwamanzi, ukufudumeza kanye nezinye izinhlelo zamapayipi ezindaweni ezibandayo ezisenyakatho, ihlinzeka ngezinsizakalo ezinokwethenjelwa kubahlali namabhizinisi. .

I-Ductile Iron Water Pipesebeyimpahla yamapayipi ebaluleke kakhulu futhi ebalulekile ekwakhiweni kwengqalasizinda yesimanje enezici zabo zokusebenza ezinhle kakhulu. Ukusuka ekuhlinzekweni kwamanzi emadolobheni kanye nokugeleza kwamanzi kuya ekuhanjisweni kwegesi, kusukela ekukhiqizweni kwezimboni kuya kumaphrojekthi okonga amanzi, amapayipi ensimbi adlala indima ebalulekile emikhakheni ehlukahlukene futhi abe negalelo elibalulekile ekuqinisekiseni izinga lempilo yabantu kanye nokuthuthukisa umnotho. Ngokuthuthuka okuqhubekayo kanye nokusha kobuchwepheshe, ukusebenza kwamapayipi e-iron ductile kuzoqhubeka nokuba ngcono, futhi ububanzi bokufaka isicelo buzonwetshwa ngokwengeziwe. Bazoqhubeka nokugqama ekwakhiweni kwengqalasizinda esikhathini esizayo. .
