Ityhubhu yesikwere egalelwe ngesinyithi kunye netyhubhu yoxande

Inkcazo emfutshane:

Ipayipi engxande egayiweyo ligama lepayipi yesikwere kunye nepayipi engxande, oko kukuthi, iipayipi zentsimbi ezinobude obulinganayo emacaleni. Yenziwa ngomcu wentsimbi oqengqelekayo emva konyango lwenkqubo. Ngokubanzi, intsimbi engumcu iyasuswa, ithambe, ikrwelwe, kwaye idityaniswe ukuze yenze ityhubhu engqukuva, emva koko ityhubhu engqukuva iqengqelelwa kwityhubhu yesikwere ize inqunyulwe kubude obufunekayo. Ngokwesiqhelo iziqwenga ezingama-50 ngepakethi nganye. Ikwaziwa njengentsimbi engenanto enesikwere kunye nengxande eyenziwe ngomxube obandayo, efinyezwa njengetyhubhu yesikwere kunye netyhubhu engxande, iikhowudi ziyi-F kunye ne-J ngokulandelelana.

Iinkcukacha zeMveliso

Iithegi zeMveliso

1. Ukuphambuka okuvumelekileyo kobukhulu bodonga lwetyhubhu exande egqunyiweyo akumele kudlule i-plus okanye i-minus 10% yobukhulu bodonga obuqhelekileyo xa ubukhulu bodonga bungaphantsi kwe-10mm, kwaye xa ubukhulu bodonga bungaphezulu kwe-10mm, buyi-plus okanye i-minus 8% yobukhulu bodonga. Ngaphandle kobukhulu bodonga kwindawo yomthungo.

2. Ubude obuqhelekileyo bokuhambisa ityhubhu engxande ekhazimlisiweyo yi-4000mm-12000mm, uninzi lwayo yi-6000mm kunye ne-12000mm. Iipayipi ezingxande zivumelekile ukuhambisa iimveliso ezimfutshane nezingenazingqiniba ezingaphantsi kwe-2000mm, kwaye zinokuthunyelwa ngendlela yeepayipi zokudibanisa, kodwa umthengi kufuneka anqumle ipayipi yokudibanisa xa eyisebenzisa. Ubunzima beemveliso ezimfutshane nezingenazingqiniba azifanele zidlule i-5% yomthamo wokuhambisa uwonke, kwaye kwiityhubhu ezingxande ezisikwere ezinobunzima obungaphezulu kwe-20kg/m, azifanele zidlule i-10% yomthamo wokuhambisa uwonke.

3. Ukugoba kwetyhubhu exande ekhazimlisiweyo akumele kube ngaphezu kwe-2mm ngemitha nganye, kwaye ukugoba okupheleleyo akumele kube ngaphezu kwe-0.2% yobude bonke.

Intshayelelo yoHlelo

1. Inkqubo yokuvelisa udidi lwetyhubhu engunxande
Iityhubhu eziziingxande zahlulwe ngokwenkqubo yemveliso: iityhubhu zesikwere ezingenanto ezigoqwe ngobushushu, iityhubhu zesikwere ezingenanto ezitsalwe ngobandayo, iityhubhu zesikwere ezingenanto ezikhutshiweyo, kunye neetyhubhu zesikwere ezidibeneyo. Phakathi kwazo, umbhobho wesikwere odibeneyo wahlulwe waba: (a) Ngokwepayipi yesikwere yokuwelda yenkqubo-arc, umbhobho wesikwere wokuwelda ochaseneyo (ophindaphindayo kakhulu, ophindaphindayo), umbhobho wesikwere wokuwelda ngegesi, umbhobho wesikwere wokuwelda we-furnace (b) ngokwepayipi yesikwere yokuwelda ye-Seam ethe tye, umbhobho wesikwere wokuwelda we-spiral

2. Ukuhlelwa kwezinto zetyhubhu engunxande
Iipayipi zesikwere zahlulwe ngokwezixhobo zazo: iipayipi zesikwere zentsimbi yekhabhoni ecacileyo kunye neepayipi zesikwere ezine-alloy ephantsi. Intsimbi yekhabhoni eqhelekileyo yahlulwe yaba: Q195, Q215, Q235, SS400, 20# intsimbi, 45# intsimbi, njl.njl.; intsimbi ene-alloy ephantsi yahlulwe yaba yi-Q345, 16Mn, Q390, ST52-3, njl.njl.

3. Udidi oluqhelekileyo lwemveliso yeetyhubhu eziziingxande
Iipayipi zesikwere zahlulwe ngokwemigangatho yemveliso: iipayipi zesikwere ezisemgangathweni zesizwe, iipayipi zesikwere ezisemgangathweni zaseJapan, iipayipi zesikwere zasebukhosini, iipayipi zesikwere ezisemgangathweni zaseMelika, iipayipi zesikwere ezisemgangathweni zaseYurophu, kunye neepayipi zesikwere ezingezizo ezisemgangathweni.

4. Ulwahlulo lweemilo zecandelo letyhubhu engunxande
Iipayipi zesikwere zahlulwe ngokweemilo zazo ezinqamlezileyo: (1) iipayipi zesikwere ezilula ezinqamlezileyo-iipayipi zesikwere zesikwere, iipayipi zesikwere ezingxande (2) iipayipi zesikwere ezintsonkothileyo ezinqamlezileyo-iipayipi zesikwere ezimile okwentyatyambo, iipayipi zesikwere ezivulekileyo, iipayipi zesikwere ezirhangqiweyo, iipayipi zesikwere ezimile okwekhethekileyo

5. Ukuhlelwa konyango lomphezulu wetyhubhu engunxande
Iipayipi zesikwere zahlulwe ngokwamacandelo okunyanga umphezulu: iipayipi zesikwere ezifakwe i-hot-dip galvanized, iipayipi zesikwere ezifakwe i-electro-galvanized, iipayipi zesikwere ezifakwe ioyile, iipayipi zesikwere ezifakwe i-pickled

6. Sebenzisa udidi lwetyhubhu engunxande
