Umuyoboro w'icyuma ASTM A556 ukoreshwa cyane cyane nk'imiyoboro ikonjesha ikonje ya karubone ibyuma bitangiza amazi.
Ingano yacyo ikoreshwa ni umuyoboro wicyuma udafite uburebure bwa diameter iri hagati ya 15.9-31.8mm nubugari bwurukuta rutari munsi ya 1.1mm.
Iyi ngingo yibanze ku miyoboro yicyuma kandi ntabwo ikubiyemo U-tubes zavuzwe mubisanzwe.
Diameter yo hanze: 5/8 - 1/4 muri. [15.9 -31.8 mm].
Ubunini bw'urukuta: ≥ 0.045 muri [1,1 mm].
ASTM A556 ishyira mu byiciro bitatu,Icyiciro A2, Icyiciro B2, naIcyiciro C2.
Imiyoboro y'ibyuma igomba gukorwa na anta nkomyiinzira kandi izaba ikonje.
Imiyoboro ikonje ikonje idafite ibyuma bitanga uburebure buringaniye kandi burangije neza mugihe cyo gutunganya microstructure no kuzamura imiterere yubukorikori nkimbaraga nubukomere.Imiterere idafite icyerekezo ituma imiyoboro ihagarara neza kandi itekanye mugihe ihuye nubushyuhe bwinshi nubushyuhe, bigatuma bikenerwa mubikorwa byinganda bisaba neza kandi neza.
Nyamara, imiyoboro ikonje ikonje idafite ibyuma ihenze kuyibyaza umusaruro kuko inzira yabyo iragoye kandi bisaba ibikorwa nibikoresho bikomeye.Byongeye kandi, umusaruro wabo ugereranije ni muto cyane cyane mubikorwa byinshi, ntabwo ubukungu bwifashe nkibikorwa bishyushye, kandi rimwe na rimwe hashobora kubaho igihombo kinini, bikagabanya imikoreshereze yabyo.
Imiyoboro ikonje ikonje igomba gutunganywa nyuma yubushyuhe bwa nyuma bwo gukonjesha ku bushyuhe bwa 1200 ° F [640 ° C] cyangwa hejuru kugirango habeho guhindagurika gushimishije mu mabati no guhuza ibikoresho bya mashini nkuko byavuzwe.
Niba isesengura ryibicuruzwa ryakozwe, reba ASTM A751 kuburyo bwo kugerageza.
1. Umutungo utoroshye
Uburyo bwikizamini: ASTM A450 Igice cya 7.
Ku byiciro bigera kuri 50, umuyoboro 1 ugomba gutoranywa kugirango ugerageze.
Kubice byimyanya irenga 50, hazatorwa imiyoboro 2 kugirango isuzumwe.
2. Gukomera
Uburyo bwikizamini: ASTM A450 Igice cya 23.
Ibigereranyo biva mu tubari tubiri twipimishije kuri buri gice bizageragezwa kubukomere bwa Brinell cyangwa Rockwell.
Ubukomezi bwa Rockwell bwumuyoboro ntibushobora kurenza ibyerekanwe kumeza.
| Icyiciro | Gukomera |
| Icyiciro A2 | 72 HRBW |
| Icyiciro B2 | 79 HRBW |
| Icyiciro C2 | 89 HRBW |
3. Ikizamini cyo Kuringaniza
Uburyo bwikizamini: ASTM A450 Igice cya 19.
Ikizamini cyo gusibanganya kigomba gukorwa ku cyitegererezo kimwe uhereye kuri buri mpera yicyuma cyarangiye uhereye ku guhitamo imiyoboro itarenze 125 kuri buri gice.
4. Ikizamini cyo gutwika
Uburyo bwikizamini: ASTM A450 Igice cya 21.
Ibizamini byo gutwika bigomba gukorwa ku cyitegererezo kimwe uhereye kuri buri mpera yigituba cyarangiye, hamwe na tebes zirenga 125 zatoranijwe muri buri cyiciro.
Nta kizamini cya hydrostatike giteganijwe kumiyoboro y'ibyuma.
Nyamara, buri U-pipe igomba gupimwa hydrostatike hamwe namazi adashobora kwangirika.
Buri muyoboro ugomba gupimwa nigikoresho cyo gupima kidafite ubushobozi bwo kumenya inenge mu gice cyose cyambukiranya umuyoboro nyuma yo kuvura ubushyuhe bwo hejuru nyuma yo gushushanya ubukonje bwa nyuma.
Uburyo bwikizamini budasenya uburyo bwo KugaragazaE213, IbisobanuroE309(kubikoresho bya ferromagnetic), IbisobanuroE426(kubikoresho bitari magnetique), cyangwa IbisobanuroE570irashobora guhitamo ikizamini.
Ubworoherane bukurikira ntabwo bukoreshwa mugice kigoramye cya U-tube.
Umuyoboro urangiye ugomba kuba udafite umunzani ariko urashobora kugira firime ya oxyde hejuru.
Imiyoboro irangiye igomba kuba igororotse kandi ifite impera nziza itarimo burrs.Imiyoboro igomba kuba imeze nkumukozi kandi igomba kuba idafite ubusembwa bwubuso budashobora gukurwaho muburyo bwo kwihanganira urukuta.
Kurandura ubusembwa bwubuso nkibimenyetso byo gufata, ibimenyetso bigororotse, urumuri rworoshye nu rupfu, ibyobo bitaremereye, hamwe nubunini bwikigereranyo ntibizakenerwa mugihe biri murwego rwo kwihanganira urukuta.
Imbere yimbere ninyuma yumuyoboro urangiye ugomba gutwikirwa kugirango wirinde kwangirika mugihe cyo gutwara.
Imyenda isanzwe niamavuta yo kwirinda, amarangi, cyangwaamarangi.
Guhitamo ibikoresho byo gutwikira mubisanzwe biterwa nibisabwa byihariye bisabwa byumuyoboro wibyuma, ibidukikije bigenewe gukoreshwa, nigihe cyo kurinda.
Amashanyarazi ashyushye: Ubu ni bumwe mu buryo bukunze gukoreshwa kuri ASTM A556 ibyuma.
Mu nganda zingufu, ubushyuhe bwamazi yibiryo bikoreshwa mugushushya amazi yo guteka, mubisanzwe mukuramo amavuta.Imikoreshereze yubu bwoko bwibyuma itanga uburyo bwo guhererekanya neza ingufu zumuriro, kuzamura ingufu muri rusange no gukora sisitemu.
Guhindura ubushyuhe hamwe na kondereseri: Kubera uburyo bwiza bwo guhererekanya ubushyuhe hamwe no kurwanya ruswa, ASTM A556 ibyuma nabyo birakwiriye gukoreshwa mubundi bwoko bwo guhanahana ubushyuhe hamwe na kondenseri, bikoreshwa muburyo butandukanye bwimiti, peteroli, nibindi bikorwa byinganda.
Sisitemu yumuvuduko mwinshi.
ASTM A192 / A192M- Kugaragaza ibisabwa bya tekiniki kubitereko bya karuboni idafite ibyuma bitetse bikoreshwa muri serivisi yumuvuduko mwinshi.
ASTM A210 / A210M- Igipimo cya karubone iciriritse hamwe na karubone-manganese ibyuma bitekesha ibyuma na superheater.
ASTM A213 / A213M- Itanga ibipimo bya ferritic na austenitis alloy ibyuma bitetse, superheater, hamwe nigituba cyo guhinduranya ubushyuhe.
ASTM A249 / A249M- Ibipimo ngenderwaho bikoreshwa mubyuma bya austenitike byo gusudira, superheater, guhinduranya ubushyuhe, hamwe nigituba cya condenser.
ASTM A334 / A334M- Igipimo cya karubone idafite isuderi kandi isudira hamwe na alloy ibyuma bivangwa na serivisi ya cryogenic.
Buri kimwe muri ibyo bipimo gikubiyemo ibyuma bikoreshwa mu guhanahana ubushyuhe, guteka cyangwa gukoresha ibintu bisa.Nibihe bipimo byatoranijwe biterwa nibisabwa byihariye bisabwa, nk'ubushyuhe bwo gukora, igipimo cy'umuvuduko, hamwe no kurwanya ruswa.
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.
