Umbhobho 不锈钢管（工业管）(Imibhobho yentsimbi engatyiwayo – Umzi mveliso) Ngokuqhelekileyo isetyenziselwa imibhobho yoshishino, njengokuthuthwa kwamanzi, ukutshintshiselana kobushushu, iibhoyila. Igxininisa ubukhulu bendonga, ukulinganiswa koxinzelelo, kunye neenkcukacha eziqhelekileyo (umzekelo, i-SCH10, i-SCH40).
 

2. Iiyantlukwano eziphambili isiShwankathelo

Udidi Iqinile Umgongxo Ugqaliselo lweSicelo oluPhambili Iimpawu zokuvelisa
Umjikelo/Udondolo ✅ Ewe ❌ Hayi Umatshini, ukubumba, izibophelelo Ukuqengqeleka okushushu, ukubumba, umzobo obandayo, ukugaya
Icwecwe/ipleyiti ❌ Hayi ❌ Hayi Isakhiwo, umhlobiso, iinqanawa zoxinzelelo Icwecwe elipholileyo / lishushu eliqengqelekayo (ipleyiti)
Umbhobho ❌ Hayi ✅ Ewe Ukuhlobisa, isakhiwo, ifenitshala I-Welded / itsalwa ngokubanda / ayinamthungo
Umbhobho ❌ Hayi ✅ Ewe Ukuthuthwa kolwelo, imigca yoxinzelelo oluphezulu Umthungo / i-welded, iireyithingi ezisemgangathweni
 

3. IiNgcebiso zeNkumbulo eKhawulezayo:

  • Umjikelo= Ibha engqukuva yenjongo ngokubanzi, ukulungiselela ukusetyenzwa rhabaxa

  • Intonga= Ibha encinci, ichaneke ngakumbi

  • Iphepha= Imveliso ecaba ebhityileyo (≤6mm)

  • Ipleyiti= Imveliso etyebileyo ecaba (≥6mm)

  • Umbhobho= Ukusetyenziswa kobuhle/kwisakhiwo

  • Umbhobho= Kuthutho lwamanzi (kulinganiswe ngoxinzelelo / umgangatho)

 

I. I-ASTM (uMbutho waseMelika woVavanyo kunye neZixhobo)

Rod / Round Bar

  • Umgangatho weReferensi: I-ASTM A276 (Ucaciso oluQhelekileyo lweeBha zentsimbi eStainless kunye neeMilo-I-Hot-Rolled and Cold-Drawn)

  • Ingcaciso: Imivalo eqinileyo enamacandelo ahlukeneyo anqamlezayo (ejikelezayo, isikwere, i-hexagonal, njl.njl.) esetyenziselwa ulwakhiwo jikelele kunye nosetyenziso lwe-machining.

  • Phawula: Kwisigama se-ASTM, “ibha engqukuva” kunye “nentonga” zihlala zisetyenziswa ngokutshintshanayo. Nangona kunjalo, "intonga" ibhekisa kwidayamitha encinci, iibha ezitsalwa ngokubanda ezinobume obuchanekileyo obuphezulu.
