ASTM A500 ni ubukonje bwubatswe kandi budasubirwaho ibyuma bya karubone byubatswe byubatswe kubiraro, gusudira, cyangwa guhindagurika ibiraro hamwe nubwubatsi hamwe nintego rusange.
Icyiciro B.ni imbeho itandukanye ikonjesha cyangwa idafite kashe ya karubone yubatswe ifite imbaraga zitanga umusaruro uri munsi ya 315 MPa [46.000 psi] n'imbaraga zingana na munsi ya 400 MPa [58.000], ikoreshwa muburyo butandukanye bwububiko n'imashini zubaka imashini bitewe nuburyo bwiza bwimiterere ihamye kandi iramba.
ASTM A500 ishyira umuyoboro wibyuma mubyiciro bitatu,icyiciro B,icyiciro C., n'icyiciro D..
Imiyoboro hamwediameter hanze ≤ 2235mm [88in]nauburebure bw'urukuta ≤ 25.4mm [1in].
Nyamara, niba hakoreshejwe uburyo bwo gusudira ERW, hashobora gukorwa imiyoboro gusa ifite diameter ntarengwa ya mm 660 hamwe nuburebure bwurukuta rwa mm 20.
Niba ushaka kugura umuyoboro ufite uburebure bunini bwa diameter, urashobora guhitamo gukoresha inzira yo gusudira SAW.
CHS: Ibice bizengurutse ibice.
RHS: Ibice bya kare cyangwa urukiramende.
EHS: Ibice bya Elliptike.
Icyuma kizakorwa na kimwe cyangwa byinshi mubikorwa bikurikira:ogisijeni shingiro cyangwa itanura ryamashanyarazi.
Uburyo bwibanze bwa Oxygene: Ubu ni uburyo bugezweho bwihuse bwo gukora ibyuma, bigabanya ibirimo bya karubone mu guhumeka ogisijeni mu cyuma cy’ingurube cyashongeshejwe mu gihe ukuraho ibindi bintu udashaka nka sulfure na fosifore.Irakwiriye kubyara umusaruro mwinshi wibyuma.
Amashanyarazi y’amashanyarazi: Inzira y’amashanyarazi ikoresha amashanyarazi yo mu rwego rwo hejuru kugira ngo ishongeshe ibice kandi igabanye ibyuma mu buryo butaziguye, kandi ni ingirakamaro cyane mu gutanga amanota yihariye no kugenzura ibihimbano, ndetse no kubyara umusaruro muto.
Imiyoboro izakorwa naamashanyarazi-arwanya-gusudira (ERW)inzira.
Umuyoboro wa ERW ni inzira yo gukora weld mugutekesha ibikoresho byuma muri silinderi hanyuma ugashyiraho imbaraga nigitutu muburebure bwacyo.
Icyiciro cya B tubing irashobora gushyirwaho cyangwa kugabanya imihangayiko.
Ibigize imiti ya ASTM A500 Icyiciro cya B kirimo urugero ruto rwa karubone na manganese kugirango habeho imashini nziza no gusudira.Muri icyo gihe, urugero rwa fosifore na sulferi bigenzurwa cyane kugirango birinde kwinjizwa, kandi kongeramo mu buryo buringaniye bw'umuringa biteza imbere kurwanya ruswa.
Iyi mitungo ikwiranye nuburyo bukoreshwa mubikorwa, cyane cyane mubidukikije aho bisabwa gusudira neza no kuramba.
Ibigereranyo byujuje ibyangombwa bisabwa bya ASTM A370, Umugereka A2.

[4.57mm].Kubyerekanwe byoroheje byurukuta, indangagaciro ntoya yo kuramba igomba kubarwa na formula: kurambura ijanisha muri 2 muri.Kuri A500M koresha formula ikurikira: 2.4t + 12, izengurutse hafi yijana. CIndangagaciro ntarengwa yo kuramba yerekanwe ikoreshwa gusa mubizamini byakozwe mbere yo koherezwa. | ||
Welddguhindagurikatest.icyitegererezo ntigishobora gucika cyangwa kumeneka imbere cyangwa hanze yimbere muriki gikorwa.
Ikizamini cyo guhindagura imiyoboro: komeza gusibanganya urugero kugeza intera iri hagati yamasahani iri munsi ya 1/2 cya diameter yo hanze.muri iki gihe, umuyoboro ntugomba kugira ibice cyangwa kuvunika hejuru yimbere ninyuma.
Ubunyangamugayotest: Komeza gusibanganya urugero kugeza igihe havunitse cyangwa kugeza igihe urukuta rugereranije ibisabwa byujujwe.Niba ibimenyetso byerekana ibishishwa, ibikoresho bitajegajega, cyangwa gusudira bituzuye biboneka mugihe cyikizamini cyo gusibanganya, icyitegererezo kizacirwa urubanza kidashimishije.
Ikizamini cyaka cyane kiraboneka kumiyoboro izenguruka mm 254 mm (10 in) ya diametre, ariko ntabwo ari itegeko.
Imiyoboro yose igomba kuba idafite inenge kandi igomba kuba imeze nkumukozi.
Ubusembwa bwubuso bugomba gushyirwa mubusembwa mugihe ubujyakuzimu bwabwo bugabanya uburebure bwurukuta rusigaye kugeza munsi ya 90% yubugari bwagenwe.
Inenge igera kuri 33% yuburebure bwurukuta rwerekanwe mubwimbitse irashobora kuvaho burundu mugukata cyangwa gusya kugirango ibyuma byuzuye.
Niba gusudira kuzuye kwakoreshejwe, hazakoreshwa uburyo bwo gusudira butose kandi icyuma gisudira gisohoka kigakurwaho kugirango kibungabunge neza.
Ubuso bwubuso, nkibimenyetso byerekana, ibimenyetso bito cyangwa ibizunguruka, cyangwa ibyobo bitaremereye, ntibifatwa nkinenge mugihe bishobora gukurwaho mubugari bwurukuta rwerekanwe.
Amakuru akurikira agomba kubamo:
Izina ry'umukoresha: Iri rishobora kuba izina ryuzuye ryakozwe cyangwa impfunyapfunyo.
Ikirango cyangwa ikirango: Izina ryikirango cyangwa ikirango gikoreshwa nuwabikoze kugirango atandukanye ibicuruzwa byayo.
Ibishushanyo mbonera: ASTM A500, idakeneye umwaka watangarijwe.
Ibaruwa yo mu cyiciro: B, C cyangwa D.
Kubitereko byubatswe ≤ 100mm (4in) ya diametre, ibirango birashobora gukoreshwa mugushiraho amakuru yibiranga neza.
Byibanze bikoreshwa mubikorwa byubaka, bitanga imbaraga zikenewe za mashini hamwe no gusudira kugirango dushyigikire igishushanyo mbonera cyubwubatsi nubwubatsi.
Uyu muyoboro wibyuma ukoreshwa cyane mukubaka amakadiri, ibiraro, inganda zinganda, nibindi bikoresho bitandukanye byubaka bisaba imbaraga nigihe kirekire.
ASTM A370: Uburyo bwikizamini nubusobanuro bwo gupima imashini yibicuruzwa byibyuma.
ASTM A700: Ubuyobozi bwo gupakira, gushyira akamenyetso, hamwe nuburyo bwo gupakira ibicuruzwa byibyuma byoherezwa.
ASTM A751: Uburyo bwikizamini nuburyo bwo gusesengura imiti yibicuruzwa byuma.
ASTM A941 Amagambo ajyanye nicyuma, ibyuma bitagira umwanda, Amavuta ajyanye, na Ferroalloys.
Ukurikije ibyifuzo byabakiriya, kuvura anti-ruswa hejuru yicyuma gishobora gukorwa muburyo bwinshi butandukanye kugirango irusheho kwangirika no kuramba.
Harimo varish, irangi, galvanisation, 3PE, FBE, nubundi buryo.
Turi abanyabugeni bo mu rwego rwo hejuru basudira ibyuma bya karuboni kandi bitanga ibicuruzwa biva mu Bushinwa, kandi tunabika ibyuma bidafite ibyuma, biguha ibisubizo byinshi byicyuma!
Niba ushaka kumenya amakuru menshi kubyerekeye ibicuruzwa biva mu byuma, ushobora kutwandikira！
