ASTM A334 tubes ni karubone na alloy ibyuma byateguwe kubushyuhe buke kandi bigakorwa hifashishijwe uburyo budasubirwaho.
Ingano y'ibicuruzwa bimwe ntishobora kuboneka munsi yibi bisobanuro kuko uburebure bwurukuta ruremereye bigira ingaruka mbi kumiterere yubushyuhe buke.
Ibyiciro
ASTM A334 ikubiyemo amanota menshi kubidukikije bitandukanye.
Icyiciro cya 1, Icyiciro cya 3, Icyiciro cya 6, Icyiciro cya 7, Icyiciro cya 8, Icyiciro cya 9, Icyiciro cya 11.
Amanota yaumuyoboro wa karuboneniIcyiciro cya 1naIcyiciro cya 6.
Impamyabumenyi ijyanye naibyuma bivanga ibyuma ni icyiciro cya 3, icyiciro cya 7, icyiciro cya 8, icyiciro cya 9, nicyiciro cya 11.
Buri cyiciro cyibyuma bifite imiterere yihariye yimiti nibisabwa byumutungo wa mashini, kimwe nibipimo byibura ibipimo byubushyuhe bigomba kuba byujujwe.
Uburyo bwo Gukora
Imiyoboro igomba gukorwa nanta nkomyicyangwa mu buryo bwikorauburyo bwo gusudiranta kongeramo ibyuma byuzuza mubikorwa byo gusudira.
Kuvura Ubushuhe
Icyiciro cya 1, 3, 6, 7, na 9
Ubusanzwe ushyushya ubushyuhe bumwe butarenze 1550 ° F [845 ° C] hanyuma ukonje mu kirere cyangwa mu cyumba gikonjesha cy’itanura rigenzurwa n’ikirere.
Niba ubushyuhe bukenewe, bizakenera kumvikana.
Kubyiciro byavuzwe haruguru byicyuma kitagira ibyuma gusa:
Shyushya kandi ugenzure akazi gashyushye hamwe nubushyuhe bwibikorwa bishyushye kugeza ubushyuhe burangiye kuva 1550 - 1750 ° F [845 - 955 ℃] hanyuma ukonje mu itanura ryikirere riyobowe nubushyuhe bwambere butari munsi ya 1550 ° F [ 845 ° C].
Icyiciro cya 8
Hitamo bumwe muburyo bukurikira bwo kuvura ubushyuhe.
Kuzimya no kurakara;
Inshuro ebyiri zisanzwe kandi zishushe.
Icyiciro cya 11
Niba kuri anneal Icyiciro cya 11 cyicyiciro cyumvikanyweho hagati yumuguzi nuwabitanze.
Iyo imiyoboro yo mu cyiciro cya 11 ihujwe igomba kuba isanzwe mu ntera ya 1400 - 1600 ℉ [760 - 870 ° C].
ASTM A334 Ibigize imiti
Ku cyiciro cya 1 cyangwa Icyiciro cya 6, ntabwo byemewe gutanga amanota avanze kubintu byose bitari ibyo bisabwa neza.Ariko, biremewe kongeramo ibintu bikenewe kugirango deoxidation yicyuma.
Ibizamini bya ASTM A334
Ibikoresho bya mashini ntibikoreshwa mubituba bito biri munsi ya 1/8 muri.
1. Umutungo utoroshye
Kurambura byibuze kubarwa kuri buri 1/32 santimetero [0,80 mm] kugabanya uburebure bwurukuta:
Kubituba bito munsi ya 1/2 muri.
2. Ibizamini
Hitamo ubushyuhe bukwiye hamwe ningaruka zingaruka ukurikije urwego nubunini bwurukuta.

4. Ikizamini cyo Kuringaniza
Ikizamini kimwe cyo gusibanganya kigomba gukorwa ku ngero kuva kuri buri mpera yigituba kimwe cyarangiye kuri buri gice ariko ntigikoreshwa mugupima flare cyangwa flange.
5. Ikizamini cya Flare (Imiyoboro idafite uburinganire)
Ikizamini kimwe cyakongejwe kizakorwa ku ngero kuva kuri buri mpera yigitereko kimwe cyarangiye kuri buri gice, ariko ntabwo cyakoreshejwe mugupimisha.
6. Ikizamini cya Flange (Imiyoboro isudutse)
Ikizamini kimwe cya flange kigomba gukorwa kubigereranyo kuva kuri buri mpera yigituba kimwe cyarangiye kuri buri gice, ariko ntabwo cyakoreshejwe mugupimisha.
7. Hindura Ikizamini cya Flattening
Ku miyoboro isudira, ikizamini kimwe cyo guhinduranya kizakorwa ku cyitegererezo kuva kuri metero 460 z'uburebure bwuzuye.
Ikizamini cyamashanyarazi ya Hydrostatike cyangwa idafite ingufu
Buri muyoboro ugomba gupimwa bidasubirwaho amashanyarazi cyangwa kugeragezwa hydrostatike ukurikije A1016 / A1016M.
Gusaba ASTM A334 Umuyoboro wibyuma
Byibanze bikoreshwa mu gutwara amazi cyangwa gaze nka gaze karemano, amavuta, nindi miti mubushyuhe buke.
1. Sisitemu yo kuvoma Cryogenic: bikunze gukoreshwa mubwubatsi bwa sisitemu yo gutwara ibintu bya kirogenike (urugero: gaze gasanzwe ya lisukiya, azote yuzuye).Bitewe nubwiza buhebuje bwa kirogenike, irashobora kugumana imbaraga zumukanishi no gukomera kubushyuhe buke cyane.
2. Guhindura ubushyuhe hamwe na kondereseri: Guhindura ubushyuhe hamwe na kondenseri birashobora gukoreshwa neza mugukonjesha cyangwa gutunganya itangazamakuru, cyane cyane mubikorwa bya chimique na peteroli.
3. Imiyoboro y'ingutu: irashobora kandi gukoreshwa mugukora imiyoboro yumuvuduko yagenewe ibikorwa bya cryogenic.Ibyo bikoresho birashobora gukoreshwa mukubika imiti ya kirogenike cyangwa mubikorwa byinganda.
4. Sisitemu yo gukonjesha n'ibikoresho: Iyi miyoboro ikoreshwa mugutwara firigo, cyane cyane aho hakenewe ibikoresho birwanya ubushyuhe buke.
ASTM A334 Ibipimo bingana
EN 10216-4: Gupfundikanya ibyuma bitavanze kandi bivanze, byagaragaje imiterere yubushyuhe buke.
JIS G 3460: ijyanye no kuvanga ibyuma bya serivise ya cryogenic.
GB / T 18984: ikoreshwa kumiyoboro idafite ibyuma kubikoresho byumuvuduko ukabije.Irerekana mu buryo burambuye igishushanyo mbonera nogukora ibyuma bikwiranye nubushyuhe bukabije bwibidukikije.
Mugihe ibi bipimo bishobora gutandukana muburyo burambuye nibisabwa byihariye, birasa mubikorwa rusange no kubishyira mubikorwa, aribyo kurinda umutekano no gukora imiyoboro yicyuma mubidukikije.
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.
