Kushandiswa kweSpiral Steel PipemuUrban Central Heating

Urban central heat inogadzirwa nekupisa kwakadzika kwechiutsi, mvura inopisa inopa nyoro simbi pombi network kuburikidza neguta kana zvikamu zvekudziya zvinoshandiswa mukugadzira uye nzira yekugara, iyo inosanganisira kupisa, kupisa network, kupisa vashandisi vezvikamu zvitatu.

Urban central heat system, iyo hupfumi hwemaguta uye budiriro yemagariro, zvivakwa, uye nhanho yebudiriro chiratidzo chekuvandudzwa kwemadhorobha.Kuvandudzwa kwenzvimbo yekudziya yedhorobha rekuvaka kwedhorobha muChina rave mutemo wekutanga.

Central heat cogeneration uye yakagoverwa kunyanya kune hukuru hwekupisa kuenzanisa, inotariswa munzvimbo dzinotevera:

1, kune kukosha kwakanaka kwemari.Maboilers ekudziya kwepakati ane hukuru hukuru, yakakwira yekupisa inoshanda inogona kusvika 90%, uye yakapararira diki bhaira yekudziya yekudziya yekudziya inongoita 60% kana zvishoma.Naizvozvo, pachinzvimbo chekupararira kwemadhorobha kupisa kupisa pamwe chete kunogona kuchengetedza 20 kusvika 30% yesimba.

2, yakanaka mabhenefiti ezvakatipoteredza.Kusvibiswa kwemaguta kunouya zvakanyanya kubva mukupisa kwemarasha kwakananga kunoburitsa kabhoni dhaikisaidhi nesoot.Central inodziya boiler simba, uye kuve nemidziyo iri nani yekubvisa guruva, uchishandisa yakakwira-inoshanda sefa, guruva rekubvisa chiyero che90 kusvika 98% kana kunyange yakakwira, inogona kunyatso kudzikisa kusvibiswa kwemaguta.

3, zvakanaka zvekugarisana zvakanaka.Urban central kudziyisa kuitira kurerutsira kwekugara kwevanhu, kuchengetedza akakosha ekuvaka emudhorobha nzvimbo, kurerutsa mamiriro ekushomeka kwemagetsi munzvimbo dzemudhorobha dzakakosha zvikuru.

Iko Kushandiswa kweSimbi Pipe muMarineuye OceanKuvaka

Ocean engineering simbi pombi dhizaini uye kusarudzwa, kutsanangurwa kunoenderana nechikamu chegungwa engineering simbi chimiro, uye zvichireva API (American petroleum Institute), AISC (American nzanga yesimbi chimiro), ASTM (American nzanga yekuyedza uye zvinhu. ), ANSI (American National Standards Institute), ASTM (American Society of Testing and Equipment), AWS (American welding society), NACE (National Association of Corrosion Engineers) mitemo uye nhungamiro.Kudiwa kwemakungwa einjiniya simbi pombi zvinhu, zvinonyanya kudiwa kwesimbi ndiro pachayo, ine yakaderera kabhoni simbi, yakakwirira simba simbi, Ultra-yakakwirira simba simbi, Stainless simbi zvikamu zvina.Taura zvinhu zviviri pano:

(1) mainjiniya emakungwa emidziyo inotengeswa kunze kwenyika zvakanyanya.Dzimwe nguva kuBritish simbi chubhu uye simbi chubhu kugadzirwa inonyanya kukwirira mhando zvinodiwa.Muinjiniya yegungwa ndeyenzvimbo yakakosha yechubhu yesimbi, 100% yayo yese inodiwa kune weld ultrasonic bvunzo (UT - Ultrasonictesting) uye magineti kuongorora (MT - Magnetictesting).Inosanganisirwa muchimiro chikuru chepombi yesimbi, muhupamhi hwe300 mm pamigumo yese yelongitudinal seam inoda 100% UT uye MT.

(2) kugadzirwa kwepombi node ndeyezvinhu zvakakosha muinjiniya yegungwa.Special pipe node mafekitori kunze kwenyika, uye epamba anovakwa unit.Kugona kwe52000 matani, semuenzaniso, "hushamwari" hwegungwa reBohai, inoyangarara yekugadzira yekuchengetedza unit (FPSO, uye dzidzisa imwe yeChina yepamusoro gumi yakakurumbira kutakura) yeiyo yakakosha nyoro ruoko (YOKE) iyo YOKE mooring system uye tsigiro bracket, iyo torch torch, helicopter platform support, etc. Kune 221 nodes, kusangana nezvinodiwa zveAISC, AWS.59 km kureba pombi (kusanganisira kure kudzora hydraulic chubhu 28 km, 119 remote control valve, tank deck 48 road).Shipyard kuitira kuve nechokwadi chemhando yekuvaka, sarudza kubva kuzviuru zvewelder makumi emakumi emhando yepamusoro welding, ekupedzisira gumi neshanu anokodzera se 6 gr yeboka remapoka.Muinjiniya yegungwa kuitira kudzivirira kubuda kweoiri uye gasi muhurongwa, haigamuchirwe simbi pombi flange yekubatanidza, uye inotora argon arc welding.Matatu mapoka eTIG welder shipyard uye anoda kudzidziswa kwakakosha.
