S355JOHngumgangatho wezinto ezizezentsimbi zesakhiwo sealloyi ephantsi kwaye isetyenziselwa ikakhulu ukwenziwa kwamacandelo angaphakathi abandayo kunye neshushu.Lo mgangatho wentsimbi usekwe kumgangatho waseYurophu we-EN 10219 kwaye ulungele ngokukodwa ukwenziwa kwamacandelo angaphakathi adityanisiweyo apholileyo.
S355JOHingasetyenziselwa ukwenziwa koluhlu olubanzi lweentlobo zetyhubhu, kubandakanywa i-spiral welded tubes (SSAW), iityhubhu ezingenamthungo (SMLS), kunye ne-straight seam welded tubes (RW okanye LSAW).
Intsingiselo ye-S355JOH
"S" imele intsimbi yokwakha;"I-355" imele izinto ezinobuncinane bemveliso ye-355 MPa, eqinisekisa ukuzinza okuhle kwesakhiwo;"
I-J0H" ibhekisa kwindawo epholileyo enomgongxo enempembelelo ye-27 J kubushushu bovavanyo obuyi-0°C.
Ukwakhiwa kweekhemikhali ze-S355JOH
Ikhabhoni (C): 0.20% max.
I-Silicon (Si): 0.55% max.
IManganese (Mn): ubuninzi be-1.60%
I-Phosphorus (P): 0.035% ubukhulu.
Isulfure (S): 0.035% max.
Nitrogen (N): 0.009% ubuninzi.
I-Aluminium (Al): 0.020% ubuncinane (le mfuneko ayisebenzi ukuba intsimbi iqulethe izinto ezaneleyo zokubopha i-nitrogen)
Nceda uqaphele ukuba ukwakheka kweekhemikhali ezithile kunokwahluka ngokuxhomekeke kumvelisi kunye neenkcukacha ezithile zemveliso.Ukongezelela, ezinye izinto ezidibeneyo, ezifana ne-vanadium, i-nickel, i-copper, njl., Zingongezwa ngexesha lenkqubo yokuvelisa ukuze kuphuculwe iipropati ezithile zentsimbi, kodwa isixa kunye nohlobo lwezi zinto ezongeziweyo kufuneka zihambelane. imigangatho efanelekileyo.
Iipropati ze-S355JOH zoomatshini
Ubuncinci bamandla esivuno ubuncinci be-355 MPa;
Amaxabiso anamandla e-tensile 510 MPa ukuya kwi-680 MPa;
Ubuncinane bobude bayo budla ngokufuneka ukuba bube ngaphezu kwepesenti ezingama-20;
Kufuneka kuqatshelwe ukuba ulwandiso lunokuchaphazeleka kubungakanani besampulu, imilo, kunye neemeko zovavanyo, ngoko ke kwizicelo ezithile zobunjineli, kunokuba yimfuneko ukubhekisa kwimigangatho eneenkcukacha okanye ujonge kumthengisi wezinto eziphathekayo ukuze ufumane idatha echanekileyo.
S355JOH Imilinganiselo kunye nokunyamezela
Ukunyamezelwa kweDayimitha yaNgaphandle (D)
Kwi-diameters yangaphandle ayikho ngaphezu kwe-168.3mm, ukunyamezela ± 1% okanye ± 0.5mm, nayiphi na into enkulu.
Kwi-diameter yangaphandle engaphezu kwe-168.3mm, ukunyamezela yi-±1%.
Ukutyeba kweendonga (T) Ukunyamezela
Ukunyamezela ubungakanani bodonga ngokusekwe kubungakanani obuthile kunye nebakala lokutyeba kodonga (njengoko kubonisiwe kwitheyibhile), ngokuqhelekileyo kwi-± 10% okanye kunjalo, kulawulo oluchanekileyo lwezicelo zokutyeba eludongeni, kunokufuna umyalelo okhethekileyo.
Ukunyamezela Ubude
Ukunyamezela ubude obuqhelekileyo (L) yi -0/+50mm.
Ngobude obumiselweyo, ukunyamezela ngokuqhelekileyo ku-± 50mm.
ubude obuthile okanye ubude obuchanekileyo bunokuba neemfuneko eziqinileyo zokunyamezela, ezifuna ukuqinisekiswa ngokubonisana nomenzi ngexesha lokuodola.
Unyamezelo olongezelelweyo lweCandelo lesikwere kunye noxande
Amacandelo e-square kunye ne-rectangular anekona yangaphandle yokunyamezela i-radius ye-2T, apho i-T yindonga yodonga.
Ukunyamezela kweDiyagonal Difference
Oko kukuthi, ixabiso eliphezulu lomahluko phakathi kobude bee-diagonal ezimbini zesikwere kunye namacandelo angama-rectangular, ngokuqhelekileyo asikho ngaphezu kwe-0.8% yobude obupheleleyo.
Ukunyamezelwa kweEngile yasekunene kunye neDegree yokuJija
Ukunyamezela ngokuthe tye (okt, ukuma kwecandelo) kunye ne-twist (okt, ukuthamba kwecandelo) kukwacaciswe ngokweenkcukacha kumgangatho wokuqinisekisa ukuchaneka kwesakhiwo kunye nenkangeleko iyonke.
Kungenxa yokuzinikela kwethu ekugqweseni kuzo zonke iinkcukacha zemveliso, kudityaniswe nolwazi lwethu olunzulu kunye namava kushishino esikwaziyo ukufikelela kwisikhundla esiphambili kwimveliso yemveliso.S355JOHumbhobho wentsimbi.
Siyaqonda ukuba yonke iprojekthi ineemfuno ezingqongqo ekusebenzeni kwemathiriyeli, ke ngoko, asiboneleli ngeemveliso kuphela kodwa sibonelela ngezisombululo ezibanzi kubathengi bethu.Ukuba unazo naziphi na iimfuno zeemveliso okanye iinkonzo zethu okanye unayo nayiphi na eminye imibuzo, nceda uzive ukhululekile ukuqhagamshelana nathi.Iqela lethu liqulathe iingcali ezinamava ezilungele ukukunika iinkcukacha zemveliso, izisombululo ezilungiselelweyo, kunye nenkxaso yobuchwephesha yobuchwephesha.
