Ibicuruzwa Bifitanye isano
Ingano
Birakwiriye imiyoboro yicyuma ifite diameter yo hanze ya 15.9-139.8mm.
Ibikoresho bito
Imiyoboro igomba gukorwa kuva iyishe ibyuma.
Ibyuma byiciwe ni ubwoko bwibyuma aho ogisijeni ikurwa mubyuma hiyongereyeho deoxidizer nka silicon, aluminium, cyangwa manganese mugihe cyo gushonga.
Ubu buvuzi butera ibyuma bidafite umuyaga mwinshi cyangwa ibindi byuka bya gaze, byongera uburinganire nibintu rusange byibyuma.
Uburyo bwo gukora JIS G 3461
Guhuza uburyo bwo gukora imiyoboro nuburyo bwo kurangiza.
Umuyoboro ushyushye utarangwamo ibyuma: SH
Ubukonje burangiye butagira ibyuma: SC
Nkumuriro wamashanyarazi weld wicyuma: EG
Amashanyarazi ashyushye arangije gusudira ibyuma: EH
Gukonjesha gukonje kwamashanyarazi gusudira ibyuma: EC
Iyo umuyoboro wibyuma uhimbwe no gusudira kurwanya, amasaro yo gusudira agomba gukurwa hejuru yimbere ninyuma kugirango ubuso bwumuyoboro bugende neza kuruhande.
Isaro ryo gusudira hejuru yimbere ntishobora gukurwaho mugihe umuguzi nuwabikoze babyemeye.
Ubwoko bwanyuma
Umuyoboro wibyuma ugomba kuba urangije.
Kuvura Ubushuhe
Uburyo bwo gukora umuyoboro wibyuma hamwe nicyiciro cyibikoresho bijyanye bigomba kwitabwaho muguhitamo uburyo bukwiye bwo kuvura ubushyuhe.
Inzira zitandukanye zo gukora hamwe n amanota yibikoresho birashobora gusaba uburyo butandukanye bwo kuvura ubushyuhe kugirango ugere kubintu byifuzwa na microstructure.
Ibigize imiti ya JIS G 3461
Uburyo bwo gusesengura ubushyuheigomba kuba ikurikije ibipimo biri muri JIS G 0320.
Kuvanga ibintu bitari ibyo birashobora kongerwaho kugirango ubone ibintu byihariye.
Uburyo bwaisesengura ry'ibicuruzwaigomba gukurikiza ibipimo biri muri JIS G 0321.
Iyo ibicuruzwa bisesenguwe, indangagaciro zitandukanya imiterere yimiti yuyoboro igomba kuba yujuje ibyangombwa bisabwa mu mbonerahamwe ya 3 ya JIS G 0321 ku miyoboro y’icyuma idafite imbonerahamwe na Imbonerahamwe ya 2 ya JIS G 0321 ku miyoboro y’icyuma isudira.
Imikorere ya mashini ya JIS G 3461
Ibisabwa muri rusange kubizamini byubukanishi bigomba gukurikiza ibice 7 na 9 bya JIS G 0404.
Nyamara, uburyo bwo gutoranya ibizamini byubukanishi bujyanye nibisabwa mu cyiciro cya A mu gice cya 7.6 cya JIS G 0404.
Imbaraga za Tensile, Umusaruro Utanga cyangwa Stress Yerekana, no Kurambura
Iyo ikizamini cya tensile gikozwe ku gice cya 12 cyumuringa uri munsi ya mm 8 z'ubugari bwurukuta, kurambura bigomba gukurikiza Imbonerahamwe 5.
Kurwanya Kurwanya
Ikizamini cyo Kurwanya Kurwanya ntabwo gisabwa kumuyoboro wicyuma udafite kashe.
Uburyo bwo Kugerageza Shyira icyitegererezo muri mashini hanyuma uyitondekanye kugeza intera iri hagati yimbuga zombi igeze ku giciro cyagenweH.Noneho reba urugero rwibice.
Mugihe cyo kugerageza imiyoboro ikomeye yo gusudira, umurongo uri hagati yo gusudira no hagati yumuyoboro ni perpendicular yerekeza ku cyerekezo cyo kwikuramo.
H = (1 + e) t / (e + t / D)
H: intera iri hagati ya platine (mm)
t: uburebure bwurukuta rwa tube (mm)
D: diameter yo hanze yigituba (mm)
е: guhora bisobanurwa kuri buri cyiciro cya tube.STB340: 0.09;STB410: 0.08;STB510: 0.07.
Gutwika Umutungo
Ikizamini cyumutungo wa Flaring ntabwo gisabwa kubituba bidafite kashe.
Impera imwe yikigereranyo irashya ku bushyuhe bwicyumba (5 ° C kugeza kuri 35 ° C) hamwe nigikoresho cya conique ku mfuruka ya 60 ° kugeza igihe diameter yo hanze yaguwe nikintu cya 1.2 ikagenzurwa kugirango hacike.
Iki gisabwa kireba kandi imiyoboro ifite diameter yo hanze irenga mm 101,6.
Hindura Kurwanya Kurwanya
Igice cyo guhinduranya ibizamini hamwe nuburyo bwo gukora ibizamini bizaba nkibi bikurikira.
Kata uburebure bwa mm 100 kuva igice kimwe cyumuyoboro hanyuma ukate igice cyikizamini muri kimwe cya 90 ° uhereye kumurongo weld kumpande zombi zumuzenguruko, ufata igice kirimo weld nkigice cyikizamini.
Ku bushyuhe bwicyumba (5 ° C kugeza 35 ° C) kuringaniza icyitegererezo mu isahani hamwe na weld hejuru hanyuma ugenzure icyitegererezo cyacitse muri weld.

Ikizamini cya Hydraulic cyangwa Ikizamini kidasenya
Ikizamini cya Hydraulic cyangwa kidasenya kizakorerwa kuri buri muyoboro.
Ikizamini cya Hydraulic
Fata imbere mu muyoboro byibuze cyangwa hejuru ya P byibuze amasegonda 5, hanyuma urebe ko umuyoboro ushobora kwihanganira umuvuduko udatemba.
P = 2st / D.
P: igitutu cyibizamini (MPa)
t: uburebure bwurukuta rwa tube (mm)
D: diameter yo hanze yigituba (mm)
s: 60% by'agaciro ntarengwa kagenwe k'umusaruro cyangwa impagarara.
P max.10 MPa.
Niba Umuguzi agaragaje igitutu, kirenze igitutu cyabazwe P cyangwa 10 MPa, igitutu cyikizamini cyumvikanyweho nu Muguzi nuwagikoze.
Bizasobanurwa mubyiyongereyeho 0.5 MPa niba bitarenze MPa 10 no muri 1 MPa byiyongera niba MPa 10 cyangwa irenga.
Ikizamini kidasenya
Igerageza ridasenya ibyuma byibyuma bigomba gukorwa na ultrasonic cyangwa eddy igerageza.
Kubiranga ultrasonic igenzura, ibimenyetso biva murugero rwerekana urugero rwicyiciro cya UD nkuko bigaragara muri JIS G 0582 bizafatwa nkurwego rwo gutabaza kandi bigomba kugira ibimenyetso byibanze bingana cyangwa birenze urwego rwo gutabaza.
Kubiranga eddy bigezweho, ibimenyetso biva mubisanzwe byerekanwe muri JIS G 0583 hamwe nicyiciro cya EY bizafatwa nkurwego rwo gutabaza, kandi nta kimenyetso kizaba kingana cyangwa kirenze urwego rwo gutabaza.
Imbonerahamwe yuburemere bwa JIS G 3461
Ibyatanzwe mubishushanyo mbonera bishingiye kuri formula ikurikira.
W = 0.02466t (Dt)
W: ubwinshi bwumuyoboro (kg / m)
t: uburebure bwurukuta rwumuyoboro (mm)
D: diameter yo hanze y'umuyoboro (mm)
0.02466: impinduka zo kubona W.
Inzira yavuzwe haruguru ni ihinduka rishingiye ku bucucike bwibyuma bya 7,85 g / cm³ kandi ibisubizo byegeranijwe kugeza ku mibare itatu yingenzi.

Kugaragara
Imbere ninyuma yumuringoti wibyuma bigomba kuba byoroshye kandi bitarimo inenge bidakwiye gukoreshwa.Kurwanya ibyuma byo gusudira ibyuma, uburebure bwimbere weld ≤ 0.25mm.
Ku miyoboro yicyuma ifite OD ≤ 50.8mm cyangwa uburebure bwurukuta ≤ 3.5mm, CAMPS YIMBERE ≤ 0.15mm irashobora gukenerwa.
Ubuso bwumuyoboro wibyuma urashobora gusanwa no gusya no gukata, gutunganya, cyangwa ubundi buryo.Igihe cyose urukuta rwasanwe
ni murwego rwerekanwe kwihanganira uburebure bwurukuta, kandi ubuso bwigice cyasanwe buzaba bworoshye.
Ikimenyetso
Fata uburyo bukwiye bwo kuranga amakuru akurikira.
a) Ikimenyetso cy'amanota;
b) Ikimenyetso cyuburyo bwo gukora;
c) Ibipimo: diameter yo hanze n'ubugari bw'urukuta;
d) Izina ryuwabikoze cyangwa ikiranga ikiranga.
Gusaba JIS G 3461
Ahanini ikoreshwa mu miyoboro y'amazi, imiyoboro ya flue, imiyoboro ya superheater, hamwe nu miyoboro ya preheater yo mu kirere, ibyo byuma bya karuboni bikoreshwa mu kumenya guhanahana ubushyuhe imbere no hanze yacyo.
Byongeye kandi, utu tubari dukoreshwa cyane mu nganda z’imiti n’ibikomoka kuri peteroli mu miyoboro ihinduranya ubushyuhe, imiyoboro ya kondenseri hamwe n’ibikoresho bya catalizator.
Ariko, ntibikwiriye kubitwikwa bishyushya hamwe nigituba cyo guhinduranya ubushyuhe kubushyuhe buke.
