Ukusetshenziswa kweIpayipi Lensimbi Elivunguzaku-Urban Central Heating

Ukushisa okuphakathi kwe-Urban kukhiqizwa ukushisa okugxilile kwe-steam, amanzi ashisayo ahlinzeka ngepayipi yensimbi emnene ngokusebenzisa idolobha noma izingxenye zokushisa ezisetshenziswa ekukhiqizeni nasekuphileni kwendlela yokuphila, ehlanganisa ukushisa, amanethiwekhi okushisa, abasebenzisi bokushisa bezingxenye ezintathu.

Isistimu yokushisisa emaphakathi yasemadolobheni, ukuthuthukiswa komnotho wasemadolobheni nenhlalakahle, ingqalasizinda, kanye nezinga layo lentuthuko kuwuphawu lwesimanjemanje sasemadolobheni.Ukuthuthukiswa kwendawo emaphakathi yasemadolobheni yokushisisa yokwakhiwa kwedolobha laseShayina sekuyinqubomgomo eyisisekelo.

Ukuhlanganiswa kokushisa okuphakathi futhi kusatshalaliswa ngokuyinhloko ekuphakameni kokuqhathanisa kokufudumeza, kugxilwe kulezi zindawo ezilandelayo:

1, kunenani elihle lemali.Ama-boilers okushisa okuphakathi anamandla amakhulu, ukusebenza kahle okuphezulu kokushisa kungafinyelela ku-90%, futhi ukusebenza kahle kwe-boiler encane ehlakazekile yokushisa kungama-60% noma ngaphansi.Ngakho-ke, esikhundleni sokusatshalaliswa kokushisa okumaphakathi kwedolobha ndawonye kungonga amandla angama-20 kuye kwangama-30%.

2, izinzuzo ezinhle zemvelo.Ukungcoliswa kwezindawo zasemadolobheni kuvela ikakhulukazi ekushisweni kwamalahle okuqondile kukhiqiza isikhutha kanye nomle.Umthamo wokushisisa ophakathi nendawo, futhi ube nezinto ezingcono zokususa uthuli, usebenzisa isihlungi esisebenza kahle kakhulu, izinga lokususa uthuli elingu-90 kuya ku-98% noma ngaphezulu, linganciphisa ngempumelelo ukungcoliswa kwedolobha.

3, izinzuzo ezinhle zomphakathi.Ukushisisa indawo emaphakathi nedolobha ukuze kube lula ukuphila kwabantu, ukonga izindawo eziyigugu zokwakha zasemadolobheni, ukuze kudambise isimo sokushoda kukagesi ezindaweni zasemadolobheni ezibaluleke kakhulu.

Ukusetshenziswa Kwepayipi Lensimbi kuOsolwandlekanye no-OceanUkwakha

Idizayini yepayipi yensimbi yobunjiniyela be-Ocean kanye nokukhethwa, ukucaciswa kuhambisana nokuhlukaniswa kwesakhiwo sensimbi yobunjiniyela basolwandle, futhi kubhekiselwa ku-API (isikhungo saseMelika sikaphethiloli), i-AISC (umphakathi waseMelika wesakhiwo sensimbi), i-ASTM (umphakathi waseMelika wokuhlola nezinto zokwakha. ), i-ANSI (isikhungo samazinga kazwelonke saseMelika), i-ASTM (umphakathi waseMelika wokuhlola nezinto zokwakha), i-AWS (umphakathi we-welding waseMelika), i-NACE (inhlangano kazwelonke yonjiniyela bokugqwala) izindinganiso neziqondiso.Isidingo sezinto zamapayipi ensimbi yobunjiniyela bolwandle, ngokuyisisekelo siyisidingo sepuleti lensimbi ngokwalo, linensimbi ye-carbon ephansi, insimbi enamandla amakhulu, insimbi yamandla aphakeme kakhulu, insimbi engagqwali izigaba ezine.Yisho amaphuzu amabili lapha:

(1) ubunjiniyela basolwandle bempahla engenisiwe kakhulu.Kwesinye isikhathi ukukhiqizwa kweshubhu lensimbi laseBrithani kuyizidingo zekhwalithi ephezulu.Ebunjiniyela basolwandle kungokwendawo ekhethekile yeshubhu lensimbi, i-100% yayo yonke imfuneko yokuhlolwa kwe-weld ultrasonic (UT – Ultrasonictesting) nokuhlolwa kazibuthe (MT – Magnetictesting).Kufakwe esakhiweni esiyinhloko sepayipi yensimbi, ebangeni lama-300 mm kuzo zombili iziphetho ze-longitudinal seam kudinga i-100% UT ne-MT.

(2) ukukhiqizwa kwe-pipe node kungokwakho okuqukethwe okubalulekile kwezobunjiniyela basolwandle.Izimboni ezikhethekile ze-pipe node phesheya, kanye nezasekhaya zakhiwe iyunithi.Umthamo wamathani angu-52000, isibonelo, “ubungani” bolwandle lwe-bohai, iyunithi yokugcina impahla entantayo (FPSO, nokuqeqesha enye yemikhumbi eyishumi edumile yaseShayina) ye-special soft just arm (YOKE) i-YOKE mooring system kanye nobakaki wokusekela, umbhoshongo wethoshi, ukwesekwa kweplatifomu yendiza enophephela emhlane, njll. Kukhona ama-node angama-221, ukuhlangabezana nezidingo ze-AISC, AWS.Ipayipi elingu-59 km ubude (kuhlanganisa ne-remote control hydraulic tube 28 km, 119 valvu yesilawuli kude, umgwaqo wethangi ongu-48).Indawo yomkhumbi ukuze uqinisekise ikhwalithi yokwakha, khetha ezinkulungwaneni zamashisela inqwaba ye-welding enhle kakhulu, i-15 yokugcina ifaneleka njengo-6 gr womphakathi wokuhlukanisa.In ocean engineering ukuze kuvinjwe ukuvuza kawoyela negesi ohlelweni, ayimukelwa steel ipayipi flange uxhumano, futhi usebenzisa argon arc Welding.Amaqembu amathathu we-TIG welder shipyard futhi adinga ukuqeqeshwa okukhethekile.
