Sobanukirwa ninyungu za ASTM A139 Umuyoboro wibyuma bya spiral kumiyoboro ya gazi yo munsi y'ubutaka
Intangiriro:
Ku bijyanye no gutwara gaze gasanzwe, akamaro k'imiyoboro yo munsi y'ubutaka ntishobora kuvugwa.Iyi miyoboro itanga uburyo bwiza bwo kugeza izo mbaraga mu ngo, ubucuruzi n'inganda.Kugirango umenye kuramba, kwiringirwa no kwihanganira iyi miyoboro, gukoresha ibikoresho byujuje ubuziranenge ni ngombwa.Muburyo bwinshi buboneka,ASTM A139Umuyoboro wicyuma ugaragara nkuguhitamo bidasanzwe.Muri iyi blog, tuzibira mubiranga inyungu ninyungu zituma ASTM A139 ibikoresho byo guhitamo imiyoboro ya gaze gasanzwe.

Ikizamini cya Hydrostatike
Buri burebure bwumuyoboro bugomba kugeragezwa nuwabikoze kumuvuduko wa hydrostatike uzatanga murukuta rwumuyoboro impungenge zitari munsi ya 60% yumusaruro muto wagenwe mubushyuhe bwicyumba.Umuvuduko uzagenwa nuburinganire bukurikira:
P = 2St / D.
Impinduka zemewe muburemere nubunini
Buri burebure bw'umuyoboro bugomba gupimwa ukundi kandi uburemere bwacyo ntibushobora gutandukana hejuru ya 10% hejuru ya 5.5% munsi yuburemere bwacyo, ubarwa ukoresheje uburebure bwacyo n'uburemere bwacyo muburebure.
Diameter yo hanze ntishobora gutandukana kurenza ± 1% uhereye kuri nomero yerekanwe hanze ya diameter.
Umubyimba wurukuta umwanya uwariwo wose ntushobora kurenza 12.5% munsi yubugari bwurukuta.
Uburebure
Uburebure bumwe butunguranye: 16 kugeza 25ft (4.88 kugeza 7,62m)
Uburebure bubiri bubiri: hejuru ya 25ft kugeza 35ft (7.62 kugeza 10.67m)
Uburebure bumwe: gutandukana byemewe ± 1in
Iherezo
Ibirundo by'imiyoboro bigomba kuba bifite impera zisanzwe, kandi burr ku mpera zizakurwaho
Iyo imiyoboro irangiye yerekanwe kuba bevel irangiye, inguni igomba kuba dogere 30 kugeza 35
ASTM A139: GuhitamoUmuyoboro wa gazi isanzweimirongo:
1. Imbaraga nigihe kirekire:
ASTM A139umuyoboro w'icyumaizwiho imbaraga zidasanzwe kandi zingirakamaro.Izi mico ningirakamaro kumuyoboro wa gazi karemano kuko uhora uhura nibidukikije bitandukanye nibidukikije.Igishushanyo mbonera cyumuyoboro wicyuma cyongera ubunyangamugayo bwimiterere, bikemerera kwihanganira umuvuduko mwinshi wo hanze no kugabanya ibyago byo kumeneka cyangwa guturika.
2. Kurwanya ruswa:
Imiyoboro yo munsi y'ubutaka irashobora kwangirika guterwa n'amazi, imiti y'ubutaka nibindi bintu.Umuyoboro w'icyuma ASTM A139 ukemura iki kibazo utanga ruswa irwanya ruswa.Ibi biterwa ahanini nububiko bwa sinc bukungahaye kuri zinc, butanga inzitizi yo gukingira ibintu byangirika, bikomeza kuramba kandi bikagabanya ibikenerwa kenshi cyangwa kubisimbuza.
3. Gusudira no guhinduka:
ASTM A139 umuyoboro wicyuma ufite ubudodo buhebuje, butuma ingingo zoroha, zikora neza mugihe cyo kwishyiriraho.Iyi ngingo ni ingirakamaro cyane kuriimiyoboro ya gazi isanzwe, nkuko byemeza ubusugire bwa sisitemu y'imiyoboro kandi bikagabanya ibyago byo kumeneka.Byongeye kandi, impinduramatwara yumuringa wicyuma ituma ishobora gukorwa muburyo bworoshye muburebure butandukanye na diametre kugirango ihuze ibyifuzo bitandukanye byumushinga, bityo igafasha mugukoresha neza no kugikora.
4. Ikiguzi-cyiza:
Iyindi nyungu ikomeye yo gukoresha umuyoboro wibyuma bya ASTM A139 kumiyoboro ya gaze ya gazi yo munsi y'ubutaka nuburyo bukoresha neza.Ibikoresho biramba, birwanya ruswa kandi byoroshye kwishyiriraho bigabanya kubungabunga igihe kirekire no kugura ibiciro.Ikigeretse kuri ibyo, imbaraga zayo nyinshi-uburemere bugabanya gukenera ibikoresho byinshi mugihe cyo kwishyiriraho, bivamo kuzigama muri rusange.
5. Ibidukikije:
Umuyoboro w'icyuma ASTM A139 ukorwa hifashishijwe uburyo bwangiza ibidukikije kandi ukurikiza amahame akomeye y’umutekano.Imiterere yacyo idashobora kwangirika ifasha gukumira imyuka ya gaze, amaherezo bikagabanya ingaruka z’ibidukikije.Byongeye kandi, ibyuma bisubirwamo byongera gukora bituma ibidukikije byangiza ibidukikije, bikomeza gushimangira inyungu zirambye zo gukoresha umuyoboro w’icyuma cya ASTM A139 mu miyoboro ya gaze gasanzwe.
Mu gusoza:
Guhitamo ibikoresho bikwiye imiyoboro ya gazi isanzwe ni ingenzi kugirango habeho ubwikorezi bwiza, bunoze kandi bwizewe bwiyi soko yingufu.ASTM A139 umuyoboro wibyuma ni amahitamo meza kubera imbaraga, kuramba, kurwanya ruswa, gusudira, gukoresha neza, no gutekereza kubidukikije.Imiterere yihariye ituma ihitamo ryambere kubashakashatsi n'abashinzwe imishinga bashaka kubaka imiyoboro ya gazi yo munsi y'ubutaka izahagarara mugihe cyigihe.Mugushora mubikoresho byiza nka ASTM A139 umuyoboro wibyuma, turashobora kwemeza ibikorwa remezo byo gukwirakwiza gazi irambye kandi itekanye ibisekuruza bizaza.
