S355JOHni igipimo ngenderwaho cy’ibikoresho bigenewe ibyuma bifite imiterere mike kandi gikoreshwa cyane cyane mu gukora ibice bifite imiterere ikonje n’ibishyushye. Iri gipimo ngenderwaho cy’icyuma gishingiye ku gipimo ngenderwaho cy’i Burayi cya EN 10219 kandi kibereye cyane cyane mu gukora ibice bifite imiterere ikonje bivanze n’ibyuma bivanze.
S355JOHishobora gukoreshwa mu gukora ubwoko bwinshi bw'imiyoboro, harimo imiyoboro ikoze mu buryo bw'umwuka (SSAW), imiyoboro idakora (SMLS), n'imiyoboro ikoze mu buryo bugororotse (ERW cyangwa LSAW).
Igisobanuro cya S355JOH
"S" isobanura icyuma cy’ubwubatsi; "355" isobanura ibikoresho bifite imbaraga nkeya za 355 MPa, bitanga umutekano mwiza mu by’ubwubatsi; "
J0H" yerekeza ku gice cy'ubukonje gifite ubukonje gifite ingufu z'ubukonje za 27 J ku bushyuhe bwa 0°C.
Ibinyabutabire bya S355JOH
Karuboni (C): 0.20% ntarengwa.
Silikoni (Si): 0.55% ntarengwa.
Manganese (Mn): ntarengwa 1.60%
Fosifore (P): ntarengwa 0.035%.
Sulfure (S): ntarengwa 0.035%.
Azote (N): 0.009% ntarengwa.
Aluminium (Al): 0.020% byibuze (iki gisabwa ntigikurikizwa niba icyuma kirimo ibintu bihagije bihuza azote)
Menya ko imiterere yihariye y’ibinyabutabire ishobora gutandukana bitewe n’uruganda n’ibipimo byihariye by’ibicuruzwa. Byongeye kandi, ibindi bintu bivangavanze, nka vanadium, nikeli, umuringa, nibindi, bishobora kongerwamo mu gihe cyo gukora kugira ngo hongerwe imiterere yihariye y’icyuma, ariko ingano n’ubwoko bw’ibyo bintu byongewemo bigomba kuba bihuye n’ibipimo ngenderwaho bireba.
Imiterere ya S355JOH ya Mekanike
Ingufu nkeya z'umusaruro zigera nibura kuri 355 MPa;
Ingufu zo gukurura zifite agaciro ka 510 MPa kugeza 680 MPa;
Ubusanzwe uburebure bwayo buke busabwa kuba burenga 20 ku ijana;
Bikwiye kumenyekana ko uburebure bushobora kugira ingaruka ku bunini bw'icyitegererezo, imiterere, n'imiterere y'ibizamini, bityo mu bikorwa byihariye by'ubuhanga, bishobora kuba ngombwa kureba ibipimo ngenderwaho birambuye cyangwa kubaza umutanga ibikoresho kugira ngo ubone amakuru nyayo.
Ibipimo bya S355JOH n'uburyo bwo kwihanganira
Ubwihangane bw'umurambararo w'inyuma (D)
Ku murambararo wo hanze utarenze mm 168.3, ubushobozi bwo kwihanganira ni ± 1% cyangwa ± 0.5mm, icyo ari cyo cyose kinini.
Ku murambararo wo hanze urenze mm 168.3, ubushobozi bwo kwihanganira ni ± 1%.
Ubunini bw'urukuta (T) Kwihanganira
Ubwinshi bw'urukuta bushingira ku bunini bwihariye n'ingano y'ubunini bw'urukuta (nk'uko bigaragara mu mbonerahamwe), akenshi buri kuri ± 10% cyangwa irenga, kugira ngo hagenzurwe neza uburyo inkuta zikoreshwa, bishobora gusaba ko habaho itegeko ryihariye.
Ubwihangane bw'uburebure
Ubushobozi bwo kwihanganira uburebure busanzwe (L) ni -0/+50mm.
Ku burebure buhamye, ubushobozi bwo kwihanganira ubusanzwe ni ± 50mm.
Uburebure bwihariye cyangwa uburebure nyabwo bushobora kuba bufite ibisabwa byo kwihanganira ibintu bikomeye, bigomba kugenwa habanje kugisha inama uwabikoze mu gihe cyo gutumiza.
Ubwihangane bw'inyongera ku bice by'impande enye n'ibice bya rectangular
Ibice by'impandeshatu n'iby'urukiramende bifite ubushobozi bwo kwihanganira 2T, aho T ari ubugari bw'urukuta.
Kwihanganira itandukaniro rya diagonal
Ni ukuvuga ko agaciro ntarengwa k'itandukaniro riri hagati y'uburebure bw'ibice bibiri by'impande kare n'ibice by'urukiramende, ubusanzwe ntikarenze 0.8% by'uburebure bwose.
Kwihanganira inguni y'iburyo n'ingero zo kuzunguruka
Uburyo bwo kwihanganira imiterere igororotse (ni ukuvuga imiterere y'igice) n'uburyo ihindagurika (ni ukuvuga imiterere y'igice) nabyo byasobanuwe mu buryo burambuye mu ihame kugira ngo harebwe ko imiterere y'igice ari myiza kandi ko igaragara neza muri rusange.
Ni ukubera ubwitange bwacu mu gukora neza mu buryo bwose bushoboka, hamwe n'ubumenyi bwimbitse n'uburambe dufite muri urwo rwego bituma dushobora kugera ku mwanya wa mbere mu gukoraS355JOHumuyoboro w'icyuma.
Turumva ko buri mushinga ufite ibisabwa bikomeye ku mikorere y'ibikoresho, bityo, ntabwo dutanga ibicuruzwa gusa ahubwo tunatanga ibisubizo birambuye ku bakiriya bacu. Niba ufite icyo ukeneye ku bicuruzwa cyangwa serivisi zacu cyangwa ufite ikindi kibazo, nyamuneka twandikire. Itsinda ryacu rigizwe n'abahanga b'inararibonye biteguye kuguha amakuru arambuye ku bicuruzwa, ibisubizo byihariye, n'ubufasha bwa tekiniki bw'umwuga.
