Simbi isina nguramavharuvhu zvikamu zvinobatanidza mapaipi mumapaipi.Zvinoenderana neiyo nzira yekubatanidza, inogona kukamurwa muzvikamu zvina: socket fittings, threaded fittings, flange fittings uye welded fittings.Kunyanya kugadzirwa kwezvinhu zvakafanana sepombi.Kune magokora, flanges, tees, michinjikwa (muchinjikwa misoro), uye zvinoderedza (misoro mikuru nemidiki).Gokora rinoshandiswa kutenderedza ruoko rwepombi. Iyo flange inoshandiswa kune zvikamu zvinobatanidza pombi uye pombi kune mumwe nemumwe, uye yakabatana kune pombi kupera. Iyo tee pombi inoshandiswa kunzvimbo inoungana mapaipi matatu. pombi ina-nzira inoshandiswa panzvimbo inoungana mapaipi mana. Reducers anoshandiswa apo mapaipi maviri emadhayamita akasiyana akabatana.
Parizvino, China yatove mugadziri mukuru uye mutengi wezvivakwa zvekuvaka munyika.Kubuda kwezvinhu zvakakura zvekuvaka senge simende, girazi rakafuratira, zvivakwa zvehutsanana zveceramics, matombo uye zvivakwa zvemadziro zvinotanga munyika kwemakore mazhinji.Panguva imwecheteyo, kunaka kwezvivakwa zvekuvaka kunoramba kuchivandudza, kushandiswa kwesimba uye zvigadzirwa zviri kuderera gore negore, zvinhu zvitsva zvakasiyana-siyana zvekuvaka zvinogara zvichibuda, uye zvigadzirwa zvekuvaka zviri kuramba zvichivandudzwa.
Pasi pemamiriro ekuvaka nzanga inochengetedza simba uye nekusimbisa nyika yakazvimiririra hunyanzvi hwekuvandudza, misoro yekuchengetedza simba uye hunyanzvi hwetekinoroji ndiyo ichave nzvimbo dzinopisa dzebudiriro yeindasitiri.Stainless simbi isimbi ine akati wandei kana anopfuura gumi nemaviri emakemikari zvinhu zviripo panguva imwe chete.Kana zvinhu zvakati wandei zvichigara mukubatana kwesimbi isina tsvina, pesvedzero yavo yakaoma zvakanyanya kupfuura kana iripo yega, nekuti mune iyi kesi kwete chete Funga nezve basa rechinhu chimwe nechimwe pachezvacho, uye teerera kune kwavo kuwirirana, saka chimiro chesimbi isina tsvina. simbi zvinoenderana nehuwandu hwekufurirwa kwezvinhu zvakasiyana-siyana.
Kana simbi isina tsvina inoshandiswa kugadzira mapaipi, marudzi maviri esimbi isina tsvina anowanzoshandiswa: 304 uye 316. Kuenzaniswa nemamwe mapaipi, simbi isina tsvina ine zvinotevera zvakanakira:
Good corrosion resistance. Yakasimba uye ductile. Zviri nyore kugadzira uye weld. Hazvina kuganhurwa nehuwandu hwekuyerera kwemvura, iyo yakanyanya kuyerera inogona kusvika 30 m / s. Inokodzera zvakasiyana-siyana zvemakemikari zvikamu zvemvura yekunwa.Kuchengetedza kushoma, mutengo wakaderera wehupenyu. Multiple nzira dzekubatanidza uye marudzi akasiyana emajoini. Hapana kudikanwa kwechero mushonga wekurapa mvura kunze kwekutonga kwebhakitiriya. Kwete-chepfu. 100% inogona kushandiswa zvakare. Funga mari yekutanga yekuisa.
Mari yekutanga yesimbi isina tsvina inowanzokwira, asi kune nzira dzakawanda dzekuchengetedza mari:
Hapana corrosion-resistant coating inodiwa. Mutengo wemidziyo yekuchengetedza wakaderedzwa. Simbi dzesimbi dzakareruka uye dzinoda tsigiro yemaitiro mashoma. Zvikamu zvinorema.Mari yekufambisa uye yekuisa yakaderera. Kuyerera kwakanyanya kunoreva kuti mapaipi madiki dhayamita anogona kushandiswa. Hapana corrosion allowance inodiwa, Kubvumira madziro akatetepa pombi. Hupenyu kutenderera mari.
Kunyangwe mutengo wekutanga wesimbi isina tsvina wakakwira, mutengo wekutenderera kwehupenyu unowanzo kuderera nekuda kwekuchengetedza mumitengo yekushandisa:
Smooth yemukati yepamusoro inogona kuderedza simba rinoshandiswa nepombi. Deredza nhamba yekuongorora uye mari. Deredza mari yekugadzirisa uye haifaniri kudzokororwa zvakare. Hapana chikonzero chekutsiva. Deredza nguva. Wedzera hupenyu hwebasa. 100% inogona kushandiswazve mushure mehupenyu hwesevhisi.
Kuti uve nechokwadi chekushandiswa kwakanyanya kwepombi dzesimbi isina tsvina, zvinofanirwa kuve nechokwadi kuti:Horizontal pombi dzinofanira kunge dziine chido chekufambisa mvura. Vakafa magumo anofanira kudziviswa panguva yekugadzira. Whuku inoshandisa 304, chloride <200 ppm. Whuku inoshandisa 316, chloride <1000 ppm. Use isulation zvinhu zvine low chloride content (<0.05% mvura-soluble chloride ions). Kana iyo insulation material ichave yaiswa kune wet chlorides, senge: nzvimbo dzemahombekombe.Chinhu chekudzivirira chinofanira kuwedzerwa pakati pepombi yesimbi isina tsvina uye zvinhu zvekudzivirira, senge: Aluminium foil. Use yeyakaderera chloride sealants uye anti-galling lubricant. All mvura inofanira kudirwa pakarepo mushure mekunge pombi yaongororwa hydrostatically.
