    Amapayipi ensimbi yekhabhoni ane-helical-seam ASTM A139 Grade A, B, C

    Amapayipi ensimbi yekhabhoni ane-helical-seam ASTM A139 Grade A, B, C Isithombe Esivelele
    • Amapayipi ensimbi yekhabhoni ane-helical-seam ASTM A139 Grade A, B, C
    • Amapayipi ensimbi yekhabhoni ane-helical-seam ASTM A139 Grade A, B, C

    Incazelo emfushane:

    Le ncazelo ihlanganisa amazinga amahlanu epayipi lensimbi elihlanganisiwe elenziwe ngogesi elihlanganisiwe (i-arc). Leli payipi lenzelwe ukudlulisa uketshezi, igesi noma umhwamuko.

    Ngemigqa yokukhiqiza engu-13 yamapayipi ensimbi ajikelezayo, i-Cangzhou Spiral Steel pipes group Co., Ltd. iyakwazi ukukhiqiza amapayipi ensimbi ane-helical-seam anobubanzi obungaphandle obusukela ku-219mm kuya ku-3500mm kanye nobukhulu bodonga obufika ku-25.4mm.

    Ukuhlolwa Kwamanzi

    Ubude bepayipi ngalinye kufanele buhlolwe ngumenzi ngengcindezi ye-hydrostatic ezokhiqiza odongeni lwepayipi ukucindezeleka okungaphansi kuka-60% wamandla amancane okukhiqiza ashiwo ekushiseni kwegumbi. Ukucindezela kuzonqunywa yi-equation elandelayo:
    P=2St/D

    Izinguquko Ezivumelekile Ezisindweni Nasezilinganisweni

    Ubude bepayipi ngalinye kufanele bulinganiswe ngokwehlukana futhi isisindo salo akumele sihluke ngaphezu kuka-10% noma u-5.5% ngaphansi kwesisindo salo esicatshangelwayo, esibalwa kusetshenziswa ubude balo kanye nesisindo salo ngobude beyunithi ngayinye.
    Ububanzi bangaphandle akumele buhluke ngaphezu kuka-±1% kobubanzi obujwayelekile bangaphandle obubekiwe.
    Ubukhulu bodonga nganoma yisiphi isikhathi akumele bube ngaphezu kuka-12.5% ​​ngaphansi kobukhulu bodonga obubekiwe.

    Ubude

    Ubude obungahleliwe obubodwa: 16 kuya ku-25ft (4.88 kuya ku-7.62m)
    Ubude obuphindwe kabili obungahleliwe: ngaphezu kwamafidi angu-25 kuya ku-35 (7.62 kuya ku-10.67m)
    Ubude obufanayo: ukuhlukahluka okuvunyelwe ±1in

    Ukuphela

    Izinqwaba zamapayipi kumele zifakwe iziphetho ezingenalutho, bese kuthi izimbobo ezisemaphethelweni zisuswe.
    Uma ukuphela kwepayipi okuchazwe ukuthi kube yiziphetho ze-bevel, i-engeli kufanele ibe ngama-degree angu-30 kuya kwangu-35.
