Ukusetyenziswa kweI-Spiral Steel Pipekwi-Urban Central Heating

Ukufudumeza urban central uveliswa ubushushu obugxininisiweyo womphunga, unikezelo lwamanzi ashushu uthungelwano lombhobho wentsimbi ethambileyo ngesixeko okanye iinxalenye zokufudumeza ezisetyenziswa kwimveliso kunye nendlela yokuphila, ebandakanya ubushushu, uthungelwano lobushushu, abasebenzisi bobushushu bezahlulo ezintathu.

Inkqubo yokufudumeza ephakathi edolophini, uphuhliso lwezoqoqosho kunye nophuhliso lwentlalo yasezidolophini, iziseko zophuhliso, kunye nenqanaba layo lophuhliso luphawu lokuphuculwa kwedolophu.Uphuhliso lwendawo yokufudumeza esembindini wedolophu yolwakhiwo lwasezidolophini eTshayina ibe ngumgaqo-nkqubo osisiseko.

Ukuhlanganiswa kokufudumeza okuphakathi kunye nokusasazwa ikakhulu ekuphakameni kokuthelekisa ukufudumeza, kugxilwe kwezi ndawo zilandelayo:

1, kukho ixabiso elihle lemali.Iibhoyila zokufudumeza okuphakathi kunye nomthamo omkhulu, ukusebenza kakuhle kwe-thermal kunokufikelela kwi-90%, kunye ne-boiler encinci yasasazwa ukusebenza kakuhle kwe-thermal yokufudumeza kuphela malunga ne-60% okanye ngaphantsi.Ngoko ke, endaweni yokufudumeza umbindi wedolophu ngokusasazwa kunye kunokonga i-20 ukuya kwi-30% yamandla.

2, izibonelelo ezilungileyo zokusingqongileyo.Ungcoliseko lwasezidolophini luvela ikakhulu ngokutshiswa kwamalahle ngokuthe ngqo kuvelisa ikharbon diokside kunye nothuthu.Umthamo webhoyila yokufudumeza embindini, kwaye ube nezixhobo ezingcono zokususa uthuli, usebenzisa isihluzo sobuchule obuphezulu, izinga lokususa uthuli lwe-90 ukuya kuma-98% nangaphezulu, linokunciphisa ngokufanelekileyo ungcoliseko lwedolophu.

I-3, izibonelelo ezilungileyo zentlalo.Ukufudumeza umbindi wasezidolophini ukuze kube lula ukuphila kwabantu, ukonga iziza ezixabisekileyo zokwakha zasezidolophini, ukunciphisa imeko yokunqongophala kombane kwiindawo zasezidolophini ezibaluleke kakhulu.

Ukusetyenziswa kwePipe yeNsimbi kwiOwaselwandlekunye noLwandleUkwakhiwa

Uyilo lombhobho wentsimbi yobunjineli bolwandle kunye nokukhethwa, ukucaciswa kuhambelana nokuhlelwa kolwakhiwo lwentsimbi yobunjineli bolwandle, kwaye ngokubhekisele kwi-API (iziko lepetroleum yaseMelika), i-AISC (uluntu lwaseMelika lwesakhiwo sentsimbi), i-ASTM (uluntu lwaseMelika lovavanyo kunye nezixhobo). ), i-ANSI (i-American standard standards Institute), i-ASTM (uluntu lwaseMelika lokuvavanya kunye nezinto eziphathekayo), i-AWS (i-American welding society), i-NACE (umbutho wesizwe weenjineli ze-corrosion) kunye nezikhokelo.Ukufuna izixhobo zombhobho wentsimbi yobunjineli bolwandle, ngokusisiseko yimfuneko yepleyiti yentsimbi ngokwayo, inentsimbi ephantsi yekhabhoni, intsimbi enamandla amakhulu, intsimbi eyomelele kakhulu, intsimbi engatyiwa ngamacandelo amane.Chaza amanqaku amabini apha:

(1) injineli yolwandle yezixhobo ezisuka kumazwe angaphandle kakhulu.Ngamanye amaxesha kwityhubhu yentsimbi yaseBritani kunye nokuveliswa kwetyhubhu yentsimbi kubaluleke kakhulu kwiimfuno zomgangatho ophezulu.Kubunjineli bolwandle buyindawo ekhethekileyo yetyhubhu yensimbi, i-100% yayo yonke imfuneko yovavanyo lwe-weld ultrasonic (UT - Ultrasonictesting) kunye nokuhlolwa kwamagnetic (MT - Magnetictesting).Kufakwe kwisakhiwo esiphambili sombhobho wensimbi, kuluhlu lwe-300 mm kuzo zombini iziphelo ze-longitudinal seam zifuna i-100% UT kunye ne-MT.

(2) ukuveliswa kwenode yombhobho kumxholo obalulekileyo kubunjineli bolwandle.Iifektri zombhobho ezikhethekileyo phesheya, kunye nezasekhaya zakhiwe iyunithi.Umthamo weetoni ze-52000, umzekelo, "ubuhlobo" bolwandle lwe-bohai, iyunithi yokugcina imveliso edadayo (FPSO, kunye nokuqeqesha enye yeenqanawa eziphezulu ezilishumi ezidumileyo zaseTshayina) zengalo ekhethekileyo ethambileyo nje (YOKE) inkqubo ye-YOKE kunye nesibiyeli senkxaso, itotshi, inkxaso yeqonga le-helicopter, njl. Kukho iindawo ze-221, ukuhlangabezana neemfuno ze-AISC, i-AWS.Umbhobho omde we-59 km (kubandakanywa ityhubhu yolawulo olukude ye-hydraulic eyi-28 km, i-119 ivelufa yokulawula ekude, idekhi yetanki engama-48).Indawo yeenqanawa ukuze kuqinisekiswe umgangatho wolwakhiwo, khetha kumawaka eewelder ezininzi zokuwelda okugqwesileyo, i-15 yokugqibela ifaneleka njenge-6 gr yoluntu lokuhlelwa.Kwinjineli yolwandle ukuze kuthintelwe ukuvuza kwe-oyile kunye negesi kwinkqubo, ayimkelwanga uqhagamshelo lwentsimbi yombhobho wentsimbi, kwaye yamkele i-argon arc welding.Amaqela amathathu e-TIG welder shipyard kwaye adinga uqeqesho olukhethekileyo.
