JIS G 3455ni inganda y’Ubuyapani (JIS) kuri serivisi y’umuvuduko ukabije ku bushyuhe bwa 350 ° C cyangwa munsi yayo, cyane cyane ku bice bya mashini.
Umuyoboro w'icyumani umuyoboro w'icyuma ufite imbaraga zingana na 370 MPa n'imbaraga ntoya ya 215 MPa, hamwe na karubone itarenze 0.25% hamwe na silikoni iri hagati ya 0.10% na 0.35%, kandi ikoreshwa cyane mubisabwa bisaba hejuru imbaraga hamwe no gusudira neza, nk'inyubako zubaka, ibiraro, imiyoboro y'amashanyarazi, n'ibigize ubwato.
JIS G 3455 ifite amanota atatu.STS370, STS410, STA480.
Hanze ya diameter ya 10.5-660.4mm (6-650A) (1 / 8-26B).
Imiyoboro igomba gukorwa kuva iyishe ibyuma.
Ibyuma byiciwe nicyuma cyarangije kwangirika rwose mbere yo gutabwa mu ngobyi cyangwa mu bundi buryo.Inzira igizwe no kongeramo ibiyobyabwenge nka silicon, aluminium, cyangwa manganese mubyuma mbere yuko bikomera.Ijambo "kwicwa" ryerekana ko nta reaction ya ogisijeni iba mu byuma mugihe cyo gukomera.
Mugukuraho ogisijeni, ibyuma byishe birinda gukora ibyuka bihumeka mubyuma bishongeshejwe, bityo ukirinda kwinuba no guhumeka ikirere mubicuruzwa byanyuma.Ibi bivamo ibyuma byinshi kandi byuzuye kandi bifite imashini isumba izindi hamwe nuburinganire bwimiterere.
Ibyuma byiciwe birakwiriye cyane cyane kubisabwa bisaba ubuziranenge kandi burambye, nkubwato bwumuvuduko, inyubako nini, hamwe nuyoboro hamwe nibisabwa byujuje ubuziranenge.
Ukoresheje ibyuma byiciwe kugirango ubyare imiyoboro, urashobora kwizera neza imikorere myiza nubuzima bwa serivisi ndende, cyane cyane mubidukikije biterwa n'imitwaro iremereye hamwe nigitutu.
Yakozwe hifashishijwe uburyo bwo gukora butagira ingano hamwe nuburyo bwo kurangiza.
Umuyoboro w'icyuma ushyushye utarangiritse: SH;
Ubukonje burangiye butagira icyuma: SC.
Kubikorwa byo gukora bidafite aho bihuriye, birashobora kugabanywa hafi yimiyoboro yicyuma idafite umurambararo wa diameter irenga 30mm ukoresheje umusaruro ushushe, na 30mm ukoresheje umusaruro ukonje.
Hano haribikorwa byumusaruro ushushe-urangije nta nkomyi.
Kwiyongera k'ubushyuhe buke bikoreshwa cyane cyane mugutezimbere ibikoresho, kugabanya ubukana, no kunoza ubukana, kandi bikwiranye nicyuma gikonje gikonje.
Ubusanzwe bukoreshwa mugutezimbere imbaraga nubukomezi bwibikoresho, kugirango ibyuma bibe byiza cyane guhangana nihungabana ryimashini numunaniro, akenshi bikoreshwa mugutezimbere imikorere yicyuma gikonje.
Binyuze muri ubwo buryo bwo gutunganya ubushyuhe, imiterere yimbere yicyuma itezimbere kandi imitungo yayo iratera imbere, bigatuma ikoreshwa neza mugusaba inganda zikoreshwa.
Isesengura ry'ubushyuhe rigomba gukurikiza JIS G 0320. Isesengura ry'ibicuruzwa rigomba gukurikiza JIS G 0321.

Ikizamini cyo gusibanganya gishobora gusibwa keretse iyo byagenwe ukundi nuwaguze.
Shira ingero muri mashini hanyuma uyitondekanye kugeza intera iri hagati yimbuga zombi igeze ku giciro cyagenwe H. Noneho reba icyitegererezo kugirango ucike.
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:burigihe busobanurwa kuri buri cyiciro cya tube.0.08 kuri STS370: 0.07 kuri STS410 na STS480.
Birakwiriye imiyoboro ifite diameter yo hanze ya mm 50 mm.
Icyitegererezo ntigishobora gucika iyo cyunamye kuri 90 ° hamwe na diameter y'imbere inshuro 6 z'umurambararo wo hanze y'umuyoboro.
Inguni yunamye igomba gupimwa mugitangiriro cyunamye.
Umuyoboro wose wibyuma ugomba kuba hydrostatike cyangwa utageragejwekwemeza ubuziranenge n'umutekano by'umuyoboro no kubahiriza ibipimo ngenderwaho.
Ikizamini cya Hydraulic
Niba nta gitutu cyikizamini cyerekanwe, igitutu ntarengwa cya hydro test kizagenwa hakurikijwe Gahunda ya Pipe.
| Ubunini bw'urukuta | 40 | 60 | 80 | 100 | 120 | 140 | 160 |

Iyo uburebure bwurukuta rwa diameter yinyuma yumuyoboro wibyuma ntabwo ari agaciro gasanzwe mumeza yuburemere bwumuyoboro wibyuma, birakenewe gukoresha formula kugirango ubare agaciro kumuvuduko.
P = 2st / D.
P: igitutu cyibizamini (MPa)
t: uburebure bwurukuta rwumuyoboro (mm)
D: diameter yo hanze y'umuyoboro (mm)
s: 60% by'agaciro ntarengwa k'umusaruro cyangwa ibimenyetso byerekana byatanzwe.
Iyo umuvuduko ntarengwa wa hydrostatike wikigereranyo cyumubare watoranijwe urenze umuvuduko wikizamini P wabonye na formula, igitutu P kizakoreshwa nkumuvuduko muto wibizamini bya hydrostatike aho guhitamo igitutu gito cya hydrostatike kiri mumeza iri hejuru.
Ikizamini kidasenya
Ikizamini kidasenya ibyuma byicyuma bigomba gukorwa naultrasonic cyangwa eddy igeragezwa ryubu.
Kuriultrasonicubugenzuzi buranga, ibimenyetso biva murugero rwerekana urugero rwicyiciro cya UD nkuko bigaragara muriJIS G 0582bizafatwa nkurwego rwo gutabaza kandi bigomba kugira ibimenyetso byibanze bingana cyangwa birenze urwego rwo gutabaza.
Igipimo gisanzwe cyo kumenya kurieddyikizamini kizaba icyiciro cya EU, EV, EW, cyangwa EX cyerekanwe muriJIS G 0583, kandi nta kimenyetso kizaba gihwanye cyangwa kirenze ibimenyetso biva mu cyitegererezo gikubiyemo ibipimo ngenderwaho by'icyiciro cyavuzwe.
Kubindi byinshiIbipimo by'ibipimo byerekana imiyoboro hamwe n'imikorere y'umuyoboromurwego rusanzwe, urashobora gukanda.
Ingengabihe 40 imiyoboro ikwiranye nuburyo bukoreshwa hagati yingutu ziciriritse kuko itanga uburebure bwurukuta rwirinda uburemere bukabije nigiciro mugihe byemeza imbaraga zihagije.
Ingengabihe ya 80 ikoreshwa cyane mubidukikije bikenera inganda zikenera umuvuduko ukabije, nka sisitemu yo gutunganya imiti hamwe nuyoboro wa peteroli na gaze, bitewe nubushobozi bwayo bwo guhangana n’umuvuduko mwinshi hamwe n’ingaruka zikomeye z’ubukanishi bitewe n'ubunini bw’urukuta rwinshi, bitanga umutekano wongeyeho , umutekano, no kuramba.
Buri muyoboro ugomba gushyirwaho amakuru akurikira.
a)Ikimenyetso cy'amanota;
b)Ikimenyetso cyuburyo bwo gukora;
c)IbipimoUrugero 50AxSch80 cyangwa 60.5x5.5;
d)Izina ryumukoresha cyangwa ikiranga ikiranga.
Iyo diameter yo hanze ya buri tube ari nto kandi biragoye gushira akamenyetso kuri buri muyoboro, cyangwa mugihe umuguzi asabye ko buri bundle yigituba irangwa, buri bundle irashobora gushyirwaho uburyo bukwiye.
STS370 ibereye umuvuduko muke ariko ugereranije n'ubushyuhe bwo hejuru bwohereza amazi.
Sisitemu yo gushyushya: Mu gushyushya umujyi cyangwa sisitemu nini yo gushyushya inyubako, STS370 irashobora gukoreshwa mugutwara amazi ashyushye cyangwa amavuta kuko ishobora kwihanganira umuvuduko nubushyuhe muri sisitemu.
Amashanyarazi: Mu kubyara amashanyarazi, harasabwa umubare munini wumuvuduko ukabije wumuyaga mwinshi, kandi STS370 nigikoresho cyiza cyo gukora iyo miyoboro kuko irashobora kwihanganira igihe kirekire cyubushyuhe bwinshi hamwe n’ibikorwa by’umuvuduko ukabije.
Sisitemu zo mu kirere zifunitse.
Imikoreshereze yuburyo n'imashini rusange: Bitewe nuburyo bwiza bwubukanishi, STS370 irashobora kandi gukoreshwa mugukora ibintu bitandukanye byubatswe nubukanishi, cyane cyane mubisabwa aho imbaraga zogukomeretsa zisabwa.
JIS G 3455 STS370 nibikoresho bya karubone bikoreshwa muri serivisi yumuvuduko mwinshi.Ibikoresho bikurikira birashobora gufatwa nkibingana cyangwa bihwanye:
1. ASTM A53 Icyiciro B.: Bikwiranye nuburyo rusange bwububiko nubukanishi no gutwara amazi.
2. API 5L Icyiciro B.: Ku miyoboro itwara peteroli na gaze.
3. DIN 1629 St37.0: Kubijyanye nubukanishi rusange nubwubatsi.
4. EN 10216-1 P235TR1: Umuyoboro wicyuma udafite ubushyuhe bwubushyuhe bwo hejuru hamwe nibidukikije byumuvuduko mwinshi.
5. ASTM A106 Icyiciro B.: Umuyoboro wa karubone udafite icyerekezo cya serivisi yubushyuhe bwo hejuru.
6.ASTM A179.
7. DIN 17175 St35.8: Ibikoresho bitagira umuringa kubitetse hamwe nimiyoboro.
8. EN 10216-2 P235GH.
Kuva yashingwa mu 2014, Botop Steel yabaye iyambere mu gutanga imiyoboro ya karubone mu majyaruguru y’Ubushinwa, izwiho serivisi nziza, ibicuruzwa byiza, ndetse n’ibisubizo byuzuye.Isosiyete itanga imiyoboro inyuranye y’ibyuma bya karubone n’ibicuruzwa bifitanye isano na byo, birimo icyuma, ERW, LSAW, hamwe n’icyuma cya SSAW, ndetse n’umurongo wuzuye w’ibikoresho bya flanges na flanges.
Ibicuruzwa byayo bidasanzwe birimo kandi amavuta yo mu rwego rwo hejuru hamwe na austenitis ibyuma bitagira umuyonga, bigenewe guhuza ibyifuzo byimishinga itandukanye.
