    Iipayipi zentsimbi yekhabhoni ezihonjisiweyo ze-ASTM A139 zeBanga A, B, C

    Iipayipi zentsimbi yekhabhoni ezithungelweyo ze-ASTM A139 zeBanga A, B, C Umfanekiso obonisiweyo
    • Iipayipi zentsimbi yekhabhoni ezihonjisiweyo ze-ASTM A139 zeBanga A, B, C
    • Iipayipi zentsimbi yekhabhoni ezihonjisiweyo ze-ASTM A139 zeBanga A, B, C

    Inkcazo emfutshane:

    Le nkcazelo igubungela amanqanaba amahlanu ombhobho wentsimbi ye-helical-seam edityaniswe ngombane-fusion (arc). Lo mbhobho wenzelwe ukuhambisa ulwelo, igesi okanye umphunga.

    Ngemigca eli-13 yemveliso yombhobho wentsimbi ejikelezayo, iCangzhou Spiral Steel pipes group Co., Ltd. inako ukuvelisa imibhobho yentsimbi enomthungo ojikelezayo enobubanzi obungaphandle ukusuka kwi-219mm ukuya kwi-3500mm kunye nobukhulu bodonga obufikelela kwi-25.4mm.

    Uvavanyo lwe-Hydrostatic

    Ubude bombhobho ngamnye buya kuvavanywa ngumvelisi kuxinzelelo lwe-hydrostatic oluya kuvelisa eludongeni lombhobho uxinzelelo olungaphantsi kwama-60% wamandla aphantsi okuvelisa kubushushu begumbi. Uxinzelelo luya kugqitywa yile equation ilandelayo:
    P=2St/D

    Utshintsho Oluvumelekileyo Kubunzima Nobukhulu

    Ubude bombhobho ngamnye buya kulinganiswa ngokwahlukeneyo kwaye ubunzima bawo abuyi kwahluka ngaphezu kwe-10% ngaphezulu okanye i-5.5% phantsi kobunzima bawo obuqikelelwayo, obubalwe kusetyenziswa ubude bawo kunye nobunzima bawo ngobude beyunithi nganye.
    Ububanzi bangaphandle abuyi kwahluka ngaphezu kwe-±1% ukusuka kububanzi obuqhelekileyo bangaphandle.
    Ubukhulu bodonga nangaliphi na ixesha abuyi kuba ngaphezulu kwe-12.5% ​​phantsi kobukhulu bodonga obuchaziweyo.

    Ubude

    Ubude obungacwangciswanga obunye: 16 ukuya kwi-25ft (4.88 ukuya kwi-7.62m)
    Ubude obuphindwe kabini obungacwangciswanga: ngaphezulu kwe-25ft ukuya kwi-35ft (7.62 ukuya kwi-10.67m)
    Ubude obufanayo: umahluko ovumelekileyo ±1in

    Iphela

    Iipayipu mazifakelwe iziphelo ezingenanto, kwaye iziphelo ezisemaphethelweni mazisuswe.
    Xa isiphelo sepayipi esichazwe njengesiphelo se-bevel, i-engile mayibe ngama-30 ukuya kuma-35 degrees
