Umuyoboro hanze ya diameter: 10.5-660.4mm (6-650A) (1 / 8-26B)
A = DN;B = NPS.
Ibyiciro
JIS G 3455 ifite amanota atatu ukurikije imbaraga nkeya zingana zumuyoboro, aribyoSTS370, STS410, naSTS480.
Uburyo bwo Gukora
Imiyoboro igomba gukorwa mu buryo budasubirwaho ibyuma byishe.
Ibishushanyo byanyuma bigabanijwemo ubwoko bubiri, bushyushye-burangiye kandi bukonje, bitewe na diameter yo hanze hamwe nubunini bwurukuta.
| Ikimenyetso cy'amanota | Ikimenyetso cyibikorwa byo gukora | |
| Uburyo bwo gukora imiyoboro | Uburyo bwo kurangiza | |
| STS370 STS410 STS480 | Nta nkomyi: S. | Bishyushye birangiye: H. Ubukonje burangiye: C. |
Kuvura Ubushuhe
| Ikimenyetso cy'amanota | Bishyushye umuyoboro w'icyuma | Ubukonje burangiye umuyoboro w'icyuma |
| STS370 STS410 | Nkuko byakozwe. Ariko, ubushyuhe buke bwa annealing cyangwa ibisanzwe birashobora gukoreshwa nkuko bikenewe. | Ubushyuhe buke bwahujwe cyangwa busanzwe |
| STS480 | Ubushyuhe buke bwahujwe cyangwa busanzwe | |
Kuvura ubushyuhe usibye ibyatanzwe kumeza birashobora gukorwa kubwumvikane hagati yumuguzi nuwabikoze.
Ubwoko bwanyuma
Imiyoboro igomba kurangizwa nu mpera.
Niba impera yaciwe isobanuwe neza, imiterere yanyuma yimiyoboro ifite uburebure bwurukuta ≤ 22 mm igomba guhura na 30-35 °, naho ubugari bwa bevel bwurugero rwicyuma ni max 2.4mm.
Ibigize imiti ya JIS G 3455
Isesengura ry'ubushyuhe rigomba gukurikiza JIS G 0320. Isesengura ry'ibicuruzwa rigomba gukurikiza JIS G 0321.
Indangagaciro zisesengura ryumuriro zigomba guhuza nibi bikurikira:
| Ikimenyetso cy'amanota | C (Carbone) | Si (Silicon) | Mn (Manganese) | P (Fosifore) | S (Amazi) |
| max | max | max | |||
| STS370 | 0,25% | 0.10-0.35% | 0.30-1.10% | 0.35% | 0.35% |

Indangagaciro zasesenguwe ku bicuruzwa ntizigomba gusa kuzuza indangagaciro ziri mu mbonerahamwe, ariko urwego rwo kwihanganira buri kintu rugomba kuba ruhuye n'ibisabwa mu mbonerahamwe ya 3 ya JIS G 3021.
Umutungo wa mashini ya JIS G 3455
Ibisabwa muri rusange kubizamini byubukanishi bigomba gukurikiza ingingo ya 7 na 9 za JIS G 0404. Uburyo bwo gutoranya ibizamini byubukanishi bugomba gukurikiza icyiciro cya A cya JIS G 0404, ingingo ya 7.6.
Imbaraga za Tensile, Umusaruro Utanga cyangwa Stress Yerekana, no Kurambura
Uburyo bwikizamini bugomba gukurikiza ibipimo biri muri JIS Z 2241.
Ku miyoboro ikorerwa ibizamini bikoresheje urugero No 12 cyangwa No 5, kurambura bigomba kuba byujuje ibisabwa mu mbonerahamwe ya 5.
Kurwanya Kurwanya
Ikizamini gishobora gusibwa mubushishozi bwuwabikoze mugihe cyose imiyoboro yujuje ibyateganijwe neza.
Icyitegererezo gishyirwa hagati yuburyo bubiri kandi buringaniye muri compression kugeza intera H hagati yurubuga igeze ku giciro cyagenwe.Icyitegererezo noneho kigenzurwa niba cyacitse.
H = (1 + e) t / (e + t / D)
H: intera iri hagati ya platine (mm)
t: uburebure bwurukuta rwumuyoboro (mm)
D: diameter yo hanze y'umuyoboro (mm)
е: guhora bisobanurwa kuri buri cyiciro cyumuyoboro: 0.08 kuri STS370, 0.07 kuri STS410 na STS480.
Ikizamini cya Bendability
Bikoreshwa kumiyoboro ifite diameter yo hanze mm50 mm nkuko byagenwe numuguzi.
Icyitegererezo kigomba kuba kitavunitse mugihe cyunamye ku nguni ya 90 ° hamwe na diametre y'imbere inshuro 6 z'umurambararo wo hanze y'umuyoboro.Inguni yunamye igomba gupimwa mugitangiriro cyunamye.
Ikizamini cya Hydrostatike cyangwa Ikizamini kidahwitse
Ikizamini cya hydrostatike cyangwa kidasenya kizakorerwa kuri buri muyoboro.
Ikizamini cya Hydrostatike
Fata umuyoboro utari munsi y’igipimo ntarengwa cya hydrostatike yipimishije byibuze amasegonda 5 hanyuma urebe ko umuyoboro ushobora kwihanganira umuvuduko udatemba.
Mugihe Muguzi adasobanuye igitutu cyikizamini, kandi mugihe umuyoboro uhuye nigitutu gito cya hydrostatike yikizamini cyatanzwe, umuyoboro urashobora kwihanganira nta kumeneka.
| Ubunini bw'urukuta | 40 | 60 | 80 | 100 | 120 | 140 | 160 |
| Umuvuduko ntarengwa wa hydraulic, Mpa | 6.0 | 9.0 | 12 | 15 | 18 | 20 | 20 |
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 kidahwitse
Umuyoboro ugomba kugenzurwa na ultrasonic detection cyangwa eddy igezweho.
Kubiranga ultrasonic detection, ibimenyetso byerekana urugero rwerekana ibipimo ngenderwaho bya UD byerekanwe muri JIS G 0582 bizafatwa nkurwego rwo gutabaza, kandi nta kimenyetso kingana cyangwa kirenze urwego rwo gutabaza.
Kubiranga eddy bigezweho, ibimenyetso byurugero rwerekana urugero rwicyiciro cya EY nkuko bigaragara muri JIS G 0583 bizafatwa nkurwego rwo gutabaza, kandi nta kimenyetso kingana cyangwa kirenze urwego rwo gutabaza.
JIS G 3455 Igicapo c'ibipimo by'ibikoresho hamwe n'ibikorwa by'imiyoboro
Imbonerahamwe yuburemere bwibyuma
Mugihe ibipimo bidasobanuwe mumeza yuburemere bwa pipe, formula irashobora gukoreshwa mukubara.
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.
Fata ubucucike bwa 7,85 g / cm³ kumuyoboro wibyuma hanyuma uzenguruke ibisubizo kumibare itatu yingenzi.
Imiyoboro
Igipimo cyerekana amanota atanu yingengabihe 40, 60, 80, 100, 120, na 160.
Kugirango bikworohereze, dore gahunda ikoreshwa cyane 40 na gahunda 80.
JIS G 3455 Ubworoherane Buringaniye
Ibigaragara
Imbere ninyuma yumuringa igomba kuba yoroshye kandi idafite inenge idakwiye gukoreshwa.
Impera z'umuyoboro w'icyuma zigomba kuba ku mfuruka iburyo kugera ku murongo w'umuyoboro.
Ikimenyetso
Buri muyoboro ugomba gushyirwaho amakuru akurikira.
a) Ikimenyetso cy'amanota;
b) Ikimenyetso cyuburyo bwo gukora;
Umuyoboro ushyushye urangije icyuma: -SH
Umuyoboro w'icyuma urangije ubukonje: -SC
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.
Gushyira mu bikorwa JIS G 3455 Umuyoboro wibyuma
Gukora imashini: Bitewe n'imbaraga zayo nyinshi hamwe nubushyuhe bwo hejuru, ikoreshwa mugukora ibice bitandukanye byubukanishi, nkibice bya sisitemu ya hydraulic na sisitemu yo gutera peteroli nyinshi.
Sisitemu yo kuvoma inganda: Ikoreshwa cyane mubikorwa byinganda bisaba ubushobozi bwo gutwara umuvuduko ukabije, nko kuvoma munganda zikora imiti, inganda, nizindi nganda zitunganya.Bashoboye gutwara neza amavuta yumuvuduko ukabije, amazi, amavuta, nindi miti.
Amashanyarazi: Ikoreshwa mubice bikomeye nka boiler hamwe na superheater ziterwa nubushyuhe bwo hejuru hamwe nuburyo bwo gukora cyane.

Ibicuruzwa Bifitanye isano
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.
