Guhitamo neza imiyoboro idafite ibyuma mubyukuri irabizi cyane!

Nibihe bisabwa kugirango uhitemo imiyoboro yicyuma idafite ubwikorezi bwo gutwara ibintu bisanzwe bikoreshwa mubikorwa byacu? Reba incamake y'abakozi bacu b'ingutu:

Imiyoboro y'icyuma idafite icyuma ni imiyoboro y'ibyuma idafite isuderi ikozwe muburyo bwo kuvura bushyushye nko gutobora no kuzunguruka.

Nibiba ngombwa, umuyoboro ushyushye urashobora gukomeza gukonjeshwa kumiterere isabwa, ingano n'imikorere. Kugeza ubu, imiyoboro y'icyuma idafite icyerekezo (DN15-600) niyo miyoboro ikoreshwa cyane mubikoresho bikomoka kuri peteroli.

Igipimo cyo gusaba: icyuka gishyushye giciriritse cyumuvuduko mwinshi

Ubugenzuzi: Mubisanzwe imiyoboro yicyuma yo gutwara amazi igomba gukorerwa isesengura ryimiti, ikizamini cya tensile, ikizamini cya tekinike hamwe na hydraulic. GB5310, GB6479, na GB9948 imiyoboro isanzwe yicyuma, hiyongereyeho ibizamini bigomba gukorwa kumiyoboro yicyuma yo gutwara amazi, ibizamini byo gutwika nibizamini byingaruka nabyo birakenewe; ubugenzuzi bwibikorwa bisabwa kuriyi miyoboro itatu yicyuma birakaze. Igipimo cya GB6479 nacyo gikora ibisabwa byihariye kugirango ubushyuhe buke bugabanuke bwibikoresho. Usibye ibizamini rusange bisabwa imiyoboro y'ibyuma byo gutwara amazi, imiyoboro y'icyuma ya GB3087 nayo isaba ibizamini byo kunama bikonje. GB / T8163 imiyoboro isanzwe yicyuma, hiyongereyeho ibisabwa muri rusange ibisabwa kugirango imiyoboro itwara amazi itwara amazi, nkuko amasezerano abiteganya bisaba kwaguka no kwipimisha ubukonje. Ibisabwa byo gukora muri ubu bwoko bubiri bwigituba ntabwo bikomeye nkubwoko butatu bwambere.

Gukora: GB / T8163 na GB3087 imiyoboro isanzwe yicyuma ahanini yashongeshejwe mumuriro ufunguye cyangwa uhindura, kandi umwanda wabo nudusembwa twimbere ni binini. GB9948 ahanini ikoresha itanura ry'amashanyarazi. Benshi muribo binjiye mubikorwa byo gutunganya hanze yitanura, kandi ibigize nudusembwa twimbere ni bito. Ibipimo bya GB6479 na GB5310 ubwabyo birateganya ibisabwa kugirango tunonosore hanze y’itanura, hamwe n’ibigize umwanda muke hamwe nudusembwa twimbere, hamwe nubwiza bwibikoresho byo hejuru

Guhitamo: Muri rusange, umuyoboro wibyuma wa GB / T8163 ubereye amavuta, peteroli na gaze nibitangazamakuru rusange bifite ubushyuhe bwashushanyije buri munsi ya 350 ° C hamwe numuvuduko uri munsi ya 10.0MPa; kubitangazamakuru bya peteroli, peteroli na gaze, mugihe ubushyuhe bwashushanyije burenze 350 ° C Cyangwa mugihe igitutu kirenze 10.0MPa, GB9948 cyangwa GB6479 imiyoboro isanzwe yicyuma; kumiyoboro ikoreshwa muri hydrogène, cyangwa imiyoboro ikora mubidukikije bikunda kwangirika, GB9948 cyangwa GB6479 nayo igomba gukoreshwa. Imiyoboro yose ya karubone ikoreshwa mubushyuhe buke (munsi ya -20 ° C) igomba gukurikiza GB6479, kandi gusa irerekana ibisabwa kugirango ubushyuhe buke bwibintu bikabije. Ibipimo bya GB3087 na GB5310 ni ibipimo byashyizweho byumwihariko kumashanyarazi. "Amabwiriza yo kugenzura umutekano wa Boiler" ashimangira ko imiyoboro yose ihujwe na boiler iri murwego rwo kugenzura, kandi gukoresha ibikoresho nibipimo bigomba kubahiriza ibisabwa n "Amabwiriza agenga umutekano wa Boiler". Kubwibyo, zikoreshwa mubyuma, amashanyarazi, gushyushya no gutunganya peteroli. Imiyoboro rusange ya parike (itangwa na sisitemu) igomba gukurikiza GB3087 cyangwa GB5310. Birakwiye ko tumenya ko igiciro cyimiyoboro yicyuma gifite ubuziranenge bwicyuma cyiza kiri hejuru. Kurugero, igiciro cya GB9948 kiri hejuru ya 1/5 hejuru yigiciro cyibikoresho bya GB8163. Kubwibyo, mugihe uhitamo ibipimo byibikoresho byicyuma, hagomba kwitabwaho uburyo bukoreshwa, bigomba kuba byizewe kandi Kuba ubukungu. Twabibutsa kandi ko imiyoboro yicyuma ikurikije GB / T20801 na TSGD0001, GB3087 na GB8163 ntishobora gukoreshwa mu miyoboro ya GC1 (keretse umwe umwe ari ultrasonic, ubuziranenge ntiburi munsi ya L2.5, kandi burashobora kuba ikoreshwa kuri GC1 hamwe nigitutu cyo gushushanya kitarenze 4.0Mpa umuyoboro).

（二）Umuyoboro muto wa aliyumu umuyoboro udafite ibyuma

Mu bikoresho bikomoka kuri peteroli, ibyuma bikoreshwa cyane muri chromium-molybdenum hamwe na chromium-molybdenum-vanadium ibyuma bitagira ibyuma ni GB9948 “Umuyoboro w'icyuma udafite amavuta yo gucamo peteroli” GB6479 “Umuyoboro mwinshi w'icyuma udafite ibikoresho by'ifumbire” GB / T5310 “Nta nkomyi umuyoboro wibyuma kumashanyarazi mwinshi》GB9948 ikubiyemo ibyuma bya chromium-molybdenum amanota: 12CrMo, 15CrMo, 1Cr2Mo, 1Cr5Mo, nibindi. amanota y'ibikoresho: 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12Cr1MoVG, n'ibindi. Muri byo, imwe ikoreshwa cyane ni GB9948, reba hejuru kugirango ibintu bishoboke

Ip Umuyoboro w'icyuma udafite ingese

Ibisanzwe bikoreshwa mubyuma bidafite ibyuma ni:

Hariho amahame atanu: GB / T14976, GB13296, GB9948, GB6479, na GB5310. Muri byo, ibyiciro bibiri cyangwa bitatu gusa byuma bitagira ibyuma byerekana urutonde rwibipimo bitatu byanyuma, kandi ntibisanzwe bikoreshwa mubyiciro.

Kubwibyo, iyo ibyuma bidafite ingese ibyuma bidafite ibyuma bikoreshwa mubuhanga, GB / T14976 na GB13296 bikoreshwa cyane.

GB / T14976 “Umuyoboro w'icyuma utagira umuyonga wo gutwara amazi”:

Ibyiciro byibikoresho: 304, 304L nubundi bwoko 19 burakwiriye gutwara amazi muri rusange.

GB13296 “Ibyuma bitagira umuyonga ibyuma bitagira ibyuma kubitekesha no guhanahana ubushyuhe”:

Amanota y'ibikoresho: 304, 304L n'ubundi bwoko 25.

Muri byo, ultra-low-carbone idafite ibyuma (304L, 316L) ifite imbaraga zo kurwanya ruswa. Mubihe bimwe na bimwe, irashobora gusimbuza ibyuma bidafite ingese (321, 347) kugirango irwanye ruswa kubitangazamakuru; ultra-low-carbone ibyuma bidafite ibyuma bifite ubukonje buke bwo hejuru, mubisanzwe bikoreshwa gusa mubushyuhe buri munsi ya 525 ℃; ibyuma bihamye bya austenitike bidafite ibyuma byombi bifite imbaraga zo kurwanya ruswa hamwe nubushyuhe bwo hejuru bwubushyuhe bwo hejuru, ariko Ti muri 321 iroroshye okiside kandi igatakara mugihe cyo gusudira, Gutyo rero kugabanya imikorere yayo yo kurwanya ruswa, igiciro cyayo kiri hejuru cyane, ubwoko bwibikoresho bukoreshwa mubindi byinshi ibihe byingenzi, 304, 316 bifite imikorere rusange yo kurwanya ruswa, igiciro kirahendutse, nuko gikoreshwa cyane.
