ASTM A500 ni imiyoboro y'ibyuma bya karuboni ikozwe mu buryo bukonje kandi idafite umugozi ikoreshwa mu biraro bivanze, bipfundikiye, cyangwa bifunganye n'inyubako ndetse n'inyubako rusange.
Icyiciro cya Bni umuyoboro w’icyuma cya karuboni gikozwe mu buryo bukonje cyangwa gikozwe mu cyuma gikonje gifite imbaraga zo gukuraho zitari munsi ya 315 MPa [46.000 psi] n’imbaraga zo gukurura zitari munsi ya 400 MPa [58.000], ukoreshwa mu mishinga itandukanye y’ubwubatsi n’ubw’imashini bitewe n’uko uhamye kandi uramba neza mu by’ubwubatsi.
ASTM A500 ishyira imiyoboro y'icyuma mu byiciro bitatu,urwego rwa B,urwego rwa C, n'icyiciro cya D.
Ku miyoboro ifiteumurambararo wo hanze ≤ 2235mm [inchi 88]naUbugari bw'urukuta ≤ 25.4mm [1in].
Ariko, iyo hakoreshejwe uburyo bwo gusudira bwa ERW, imiyoboro ifite umurambararo ntarengwa wa mm 660 n'ubugari bw'urukuta bwa mm 20 ni yo yonyine ishobora gukorwa.
Niba ushaka kugura umuyoboro ufite ubugari bw'urukuta rufite umurambararo munini, ushobora guhitamo gukoresha uburyo bwo gusudira bwa SAW.
CHS: Ibice by'uruziga bifite ububobere.
RHS: Ibice bifite impande enye cyangwa impande enye.
EHS: Ibice bifite ububobere bwa elliptical.
Icyuma kigomba gukorwa hakoreshejwe bumwe cyangwa byinshi muri ibi bikurikira:ogisijeni y'ibanze cyangwa itanura ry'amashanyarazi.
Uburyo bw'ibanze bwa ogisijeni: Ubu ni uburyo bugezweho bwo gukora icyuma cyihuse, bugabanya ingano ya karuboni binyuze mu guhumeka ogisijeni mu cyuma cyashongeshejwe mu gihe bikuraho ibindi bintu bidakenewe nka sulfur na fosifore. Bikwiriye gukorwa byihuse icyuma kinini.
Uburyo bwo Gukoresha Ifuru Ikoresha Amashanyarazi: Uburyo bwo Gukoresha Ifuru Ikoresha Amashanyarazi akoresha ubushyuhe bwinshi kugira ngo ishongeshe ibisigazwa by'ibice no kugabanya icyuma mu buryo butaziguye, kandi ni ingirakamaro cyane cyane mu gukora imiterere yihariye no kugenzura imiterere y'ibice by'ibumba, ndetse no mu gukora uduce duto.
Imiyoboro igomba gukorwa naikoreshwa mu gusudira hakoreshejwe amashanyarazi (ERW)inzira.
Umuyoboro wa ERW ni inzira yo gukora umuyoboro w'icyuma uhuza ibikoresho by'icyuma muri silindiri hanyuma ugashyiraho uburinzi n'umuvuduko mu burebure bwabyo.
Imiyoboro ya teyine yo mu rwego rwa B ishobora gukururwa cyangwa kugabanyirizwa stress.
Ibigize icyuma cya ASTM A500 Grade B birimo ingano iringaniye ya karuboni na manganese kugira ngo bibe byiza mu mikorere ya mekanike no gusyirwa neza. Muri icyo gihe, urugero rwa fosifore na sulfure rugenzurwa cyane kugira ngo hirindwe kwangirika, kandi kongeramo umuringa mu buryo buringaniye birushaho kunoza ubudahangarwa bw'ingufu.
Iyi miterere ikwiriye cyane mu bikorwa by'inyubako, cyane cyane ahantu hakenewe ubushuhe bwiza no kuramba.
Ibipimo bigomba kuba byujuje ibisabwa na ASTM A370, Umugereka A2.

Ku bunini bw'urukuta rwagenwe bworoshye, agaciro gato k'uburebure kagomba kubarwa hakoreshejwe formula: ubwinshi bw'ijana muri 2 in. [50 mm] = 61t + 12, buzungurutswe ku ijana rya hafi. Kuri A500M koresha formula ikurikira: 2.4t + 12, buzungurutswe ku ijana rya hafi. CAgaciro ntarengwa k’uburebure kavuzwe kareba gusa ibizamini byakozwe mbere yo kohereza umuyoboro. | ||
Gusudiradubushobozitikoreshwa: Ukoresheje icyitegererezo gifite nibura santimetero 100 z'uburebure, shyira icyitegererezo mu buryo bwo gusudira kuri dogere 90 ugana aho umutwaro ushyirwa kugeza igihe intera iri hagati y'ibipande iri munsi ya 2/3 by'umurambararo w'inyuma w'umuyoboro. Icyitegererezo ntikigomba kwangirika cyangwa gucika imbere cyangwa inyuma muri iki gikorwa.
Ikizamini cyo gupima umuyoboro w'amazi: komeza kugorora icyitegererezo kugeza igihe intera iri hagati y'ibipande iri munsi ya 1/2 cy'umurambararo w'inyuma w'umuyoboro. Muri iki gihe, umuyoboro ntugomba kugira imiturire cyangwa imvune ku buso bw'imbere n'inyuma.
Ubunyangamugayotikoreshwa: Komeza kugorora icyitegererezo kugeza igihe cyavunitse cyangwa kugeza igihe ibisabwa ku bugari bw'urukuta byujujwe. Iyo habonetse ibimenyetso by'uko icyitegererezo cyacitse, ibikoresho bidakomeye, cyangwa ubushuhe budatunganyije mu gihe cyo gupima, icyitegererezo kizafatwa nk'ikidashimishije.
Ikizamini cyo gutwika kirahari ku miyoboro izengurutse ifite umurambararo wa ≤ mm 254 (inchi 10), ariko si itegeko.
Imiyoboro yose igomba kuba idafite inenge kandi ifite ishusho nk'iy'umuntu.
Ubusembwa bwo hejuru bugomba gushyirwa mu byiciro by'ubusembwa iyo ubujyakuzimu bwabwo bugabanije ubugari bw'urukuta rusigaye kugeza munsi ya 90% by'ubugari bw'urukuta rwagenwe.
Inenge zigera kuri 33% by'ubugari bw'urukuta rwagenwe mu bujyakuzimu zishobora gukurwaho burundu hakoreshejwe gukata cyangwa gusya icyuma cyose.
Iyo hakoreshejwe uburyo bwo gusudira butose, hagomba gukoreshwa uburyo bwo gusudira butose kandi icyuma gisohoka kigomba gukurwaho kugira ngo ubuso bukomeze kuba bwiza.
Inenge zo ku buso, nk'ibimenyetso byo gufata, ibimenyetso bito by'ibihumyo cyangwa ibizingo, cyangwa imyobo migufi, ntabwo zifatwa nk'inenge mu gihe zishobora gukurwa mu bunini bw'urukuta rwagenwe.
Amakuru akurikira agomba gushyirwamo:
Izina ry'uwakoze: Iri rishobora kuba izina ryuzuye ry'uwakoze cyangwa incamake.
Ikirango cyangwa Ikirango cy'Indangagaciro: Izina ry'ikirango cyangwa ikirango cy'ubucuruzi gikoreshwa n'uruganda mu gutandukanya ibicuruzwa byarwo.
Umushushanyi w'ibipimo: ASTM A500, bitari ngombwa ko ikubiyemo umwaka yasohotseho.
Ibaruwa y'icyiciro: Icyiciro cya B, C cyangwa D.
Ku miyoboro y’imiterere ifite umurambararo wa ≤ mm 100 (inchi 4), ibirango bishobora gukoreshwa mu gushyira ikimenyetso cy’amakuru ajyanye n’imiterere yayo neza.
Ikoreshwa cyane cyane mu nyubako, itanga imbaraga za mekanike n'ubushobozi bwo gusudira kugira ngo ishyigikire igishushanyo mbonera n'ubwubatsi bw'inyubako n'ubwubatsi.
Uyu muyoboro w'icyuma ukoreshwa cyane mu kubaka imbaho, ibiraro, inganda, n'ibindi bice bitandukanye by'inyubako bisaba imbaraga n'uburambe.
ASTM A370: Uburyo bwo gupima n'ibisobanuro byo gupima ibikoresho by'icyuma hakoreshejwe ikoranabuhanga.
ASTM A700: Ubuyobozi bw'uburyo bwo gupakira, gushyira ikimenyetso, no gupakira ibikoresho by'icyuma byo kohereza.
ASTM A751: Uburyo bwo gupima no gukoresha mu gusesengura ibikomoka ku byuma.
Amagambo ya ASTM A941 yerekeye icyuma, icyuma kitagira umugese, alloys zijyanye nacyo, na Ferroalloys.
Dukurikije ibyo abakiriya bakeneye, uburyo bwo kurwanya ingese ku buso bw'imiyoboro y'icyuma bushobora gukorwa mu buryo butandukanye kugira ngo bwongere ubushobozi bwo kurwanya ingese no kongera igihe cyo kuyikoresha.
Harimo vernis, irangi, galvanisation, 3PE, FBE, n'ubundi buryo.
Turi uruganda rukora imiyoboro ya karubone ikoze mu byuma bishyushye kandi rutanga serivisi nziza ruturutse mu Bushinwa, tukaba tunatanga imiyoboro y'ibyuma bishyushye kandi bidafite umugozi, tuguha ibisubizo bitandukanye by'imiyoboro y'ibyuma!
Niba ushaka kumenya amakuru arambuye ku bicuruzwa by'imiyoboro y'icyuma, ushobora kutwandikira!
