ASTM A500 ni imbeho ikozwe mu buryo bukonje kandi idafite icyuma cya karubone yubatswe kugirango isudwe, izungurutswe, cyangwa ikiraro cyubatswe hamwe ninyubako zubaka nintego rusange zubaka.
Umuyoboro wa Grade C nimwe mumanota afite imbaraga nyinshi zitanga umusaruro uri munsi ya 345 MPa nimbaraga zingana na MPa zitari munsi ya 425.
Niba ushaka kumenya byinshi kuriASTM A500, urashobora gukanda kugirango ubigenzure!
ASTM A500 ishyira umuyoboro wibyuma mubyiciro bitatu,icyiciro B., icyiciro C, n'icyiciro D..
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.
Igituba kizakorwa na anta nkomyicyangwa uburyo bwo gusudira.
Imiyoboro isudira igomba gukorwa mu byuma bizengurutswe na gahunda yo gusudira amashanyarazi (ERW).Ikibuno kirebire gifatanye cyo gusudira kizunguruka kizengurutswe hejuru yubunini bwacyo kuburyo imbaraga zububiko zubaka igice cyizerwa.
ASTM A500 Icyiciro C gishobora kugabanywa cyangwa kugabanuka.
Annealing ikorwa no gushyushya umuyoboro ubushyuhe bwinshi hanyuma ukonjesha buhoro.Annealing itunganya microstructure yibikoresho kugirango irusheho gukomera no guhuza.
Kugabanya imihangayiko muri rusange bikorwa no gushyushya ibikoresho ubushyuhe buke (mubisanzwe munsi yubwa annealing) hanyuma ukabifata mugihe runaka hanyuma ukabikonjesha.Ibi bifasha kwirinda kugoreka cyangwa guturika kw'ibikoresho mugihe gikurikiraho nko gusudira cyangwa gukata.
Inshuro y'ibizamini.
Uburyo bw'igerageza: Uburyo nuburyo bujyanye nisesengura ryimiti bigomba gukurikiza uburyo bwikizamini, imyitozo, na terminologiya A751.

Mu kizamini, icyitegererezo gishyirwa mumashini igerageza hanyuma igahinduka buhoro buhoro kugeza ivunitse.Mubikorwa byose, imashini yipimisha yandika impagarara namakuru aruhije, bityo bikabyara umurongo-uhangayitse.Uyu murongo udufasha kwiyumvisha inzira yose kuva ihindagurika rya elastike kugeza kuri plastike ihinduka kugeza kumeneka, no kubona imbaraga zumusaruro, imbaraga zingutu hamwe namakuru arambuye.
Uburebure bw'ikigereranyo: Uburebure bwikigereranyo bwakoreshejwe mugupima ntigomba kuba munsi ya 2/2 muri (65 mm).
Ikizamini cyo guhindagurika: Hatabayeho kumeneka cyangwa kuvunika, icyitegererezo kirambuye hagati yicyapa kibangikanye kugeza intera iri hagati yamasahani iri munsi yagaciro ka "H" ibarwa nuburyo bukurikira:
H = (1 + e) t / (e + t / D)
H = intera iri hagati yamasahani, muri. [Mm],
e = guhindagurika kuburebure bwa buri gice (gihoraho kumurongo watanzwe wibyuma, 0.07 kumanota B, na 0.06 kubiciro C),

Kwiyemeza neza
Ubuso bwubuso bugomba gushyirwa mubikorwa nkubusembwa mugihe ubujyakuzimu bwubuso bwubuso bumeze kuburyo uburebure bwurukuta busigaye buri munsi ya 90% yubugari bwagenwe.
Ibimenyetso byafashwe neza, ibimenyetso bito cyangwa ibizunguruka, cyangwa amenyo maremare ntibifatwa nkinenge niba bishobora gukurwaho mubipimo byubugari bwurukuta.Izi nenge zo hejuru ntizisaba gukuraho byanze bikunze.
Gusana neza
Inenge ifite ubugari bwurukuta rugera kuri 33% yubugari bwateganijwe igomba gukurwaho gukata cyangwa gusya kugeza icyuma kitagira inenge kigaragaye.
Niba gusudira tack ari ngombwa, inzira yo gusudira itose igomba gukoreshwa.
Nyuma yo gutunganya, ibyuma birenze bigomba gukurwaho kugirango ubone ubuso bunoze.
Izina ry'umukoresha.ikirango, cyangwa ikirango;kugenwa neza (umwaka w'ikibazo ntusabwa);n'urwandiko rw'amanota.
Ku miyoboro yubatswe ifite diameter yo hanze ya 4 muri cm 10 cyangwa munsi yayo, amakuru yo kumenyekanisha yemerewe kurango yometse neza kuri buri mugozi wumuyoboro.
Hariho kandi uburyo bwo gukoresha barcode nkuburyo bwinyongera bwo kumenyekanisha, kandi birasabwa ko barcode ihuza na AIAG Standard B-1.
1. Kubaka inyubako: Icyiciro cya C cyicyuma gikoreshwa mubwubatsi aho hakenewe inkunga yimiterere.Irashobora gukoreshwa kumurongo wibanze, inyubako zo hejuru, hasi, nurukuta rwinyuma.
2. Imishinga remezo: Kubiraro, ibyapa byumuhanda byubatswe, hamwe na gariyamoshi kugirango bitange inkunga ikenewe kandi iramba.
3. Ibikoresho byinganda: mugukora inganda nibindi bidukikije byinganda, birashobora gukoreshwa mugutondekanya, gushiraho sisitemu, hamwe ninkingi.
4. Ingufu zisubirwamo: Irashobora kandi gukoreshwa mukubaka inyubako zumuyaga nizuba.
5. Ibikoresho bya siporo nibikoresho: imiterere yibikoresho bya siporo nka blachers, poste yintego, ndetse nibikoresho bya fitness.
6. Imashini zubuhinzi: Irashobora gukoreshwa mukubaka amakadiri yimashini nububiko.
Ingano: Gutanga diameter yo hanze hamwe nuburebure bwurukuta kugirango tubone uruziga;tanga ibipimo byo hanze hamwe nuburebure bwurukuta kuri kare na urukiramende.
Umubare: Vuga uburebure bwose (ibirenge cyangwa metero) cyangwa umubare wuburebure bwa buri muntu usabwa.
Uburebure: Erekana ubwoko bwuburebure busabwa - butemewe, bwinshi, cyangwa bwihariye.
ASTM 500 Ibisobanuro: Tanga umwaka wo gutangaza ASTM 500 yerekanwe.
Icyiciro: Erekana urwego rw'ibikoresho (B, C, cyangwa D).
Kugenera Ibikoresho: Erekana ko ibikoresho ari imbeho ikonje.
Uburyo bwo gukora: Menyesha niba umuyoboro udafite kashe cyangwa wasuditswe.
Gukoresha Kurangiza: Sobanura imikoreshereze yagenewe umuyoboro
Ibisabwa bidasanzwe: Andika ibindi bisabwa byose bitarimo ibisobanuro bisanzwe.
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！
