Ububanzi be-Deameter kunye ne-diemeter yangaphakathi nengaphandle yombhobho wentsimbi

Umbhobho wentsimbiLuhlobo lwemibhobho yentsimbi eyenziwe ngokuqengqeleka kwi-Strip Strip kwi-Angle yombhobho kwi-angle ethile yeSpiral (yenza i-angle) emva koko uyibeka. Isetyenziswe ngokubanzi kwiinkqubo ze-pipelit zeoyile, igesi yendalo kunye nokuhanjiswa kwamanzi.

Ububanzi bokwakhiwa bububanzi bubekwe ngumbhobho, ixabiso elichanekileyo lomzekelo we-pipe. Kwimibhobho yentsimbi ye-Spiral, ububanzi bezinto ezilungileyo zihlala zikufutshane, kodwa zingalingani, ngaphakathi okanye zingaphandle.

Ihlala ibonakaliswa yi-DN kunye nenombolo, enjenge-DN200, ebonisa umbhobho wentsimbi ene-200 mm ye-200 mm.

Ubungakanani obuqhelekileyo beedayala (DN):
1. Uluhlu lwedayimitha elincinci (DN100 - DN300):
I-DN100 (i-4 intshi)
I-DN150 (i-6 intshi)
I-DN200 (i-intshi ezi-8)
I-DN250 (i-intshi ezili-10)
I-DN300 (i-12 intshi)

I-2. Uluhlu lweDaweyi-Demeter (DN350 - DN700):
I-DN350 (i-intshi ezili-14)
I-DN400 (i-intshi eziyi-16)
I-DN450 (i-intshi ezili-18)
I-DN500 (i-20 intshi)
I-DN600 (i-intshi ezingama-24)
I-DN700 (i-intshi ezingama-28)

3. Uluhlu lwedayimitha olukhulu (DN750 - DN1200)
I-DN750 (i-intshi ezingama-30)
I-DN800 (i-intshi ezingama-32)
I-DN900 (i-intshi ezingama-36)
I-DN1000 (i-intshi ezingama-40)
I-DN1100 (i-44 intshi)
I-DN1200 (i-intshi ezingama-48)

I-4. Uluhlu oluninzi lwedayamitha (DN1300 nangaphezulu)
I-DN1300 (i-intshi ezingama-52)
I-DN1400 (i-intshi ezingama-56)
I-DN1500 (i-intshi ezingama-60)
I-DN1600 (i-intshi ezingama-64)
I-DN1800 (i-intshi ezingama-72)
I-DN2000 (i-intshi ezingama-80)
I-DN2200 (i-intshi ezingama-88)
I-DN2400 (i-intshi ezingama-96)
I-DN2600 (i-intshi ezili-104)
I-DN2800 (i-intshi ezili-112)
I-DN3000 (i-intshi ezili-120)

Ububanzi bezangaphandle (i-OD): I-OD bububanzi bomphezulu we-spiral spipe spipe pipe. I-OD yombhobho wentsimbi ye-spiral yeyona ubukhulu bokwenyani ngaphandle kombhobho. I-OD inokufumaneka ngomgangatho oqhelekileyo, ihlala kwiimilimitha (mm).
I-Diameter yangaphakathi (ID) Isazisi sobukhulu obuphantsi yombhobho. Isazisi sihlala sibalwa ngokuthambisa kabini ubukhulu obuvela kwi-OD kwiimilimitha (MM) I-ID = i-OD-2 x ubukhulu bomhlaba

Ifildi yesicelo

Imibhobho yentsimbi ye-Spiral ene-Dieometer eyahlukeneyo ye-Diameter inesicelo esahlukileyo kwimimandla eyahlukeneyo:
I-1. Ububanzi obuncinciI-SSAW PIP yentsimbi.
I-2. Ububanzi obuphakathiI-SSAW PIP. I-3. Ububanzi be-Spiral Spiper Pipe (DN100 - DN300): Isetyenziswe ngokuqhelekileyo kwi-Pipeling Bipeling Ripere, i-Prainege Pipeline, iPiipeline yeGesi, njl njl.
3.I-ssamer enkulu ye-ssaw.
4. Ububanzi be-ultraI-SSAW Carbon yentsimbi yombhobho.

Ububanzi bezinto ezilungileyo kunye nolunye uhlangothi lwemibhobho yentsimbi yeSpiral zihlala ziveliswa ngokwemigangatho efanelekileyo kunye neenkcazo:
I-1. Imigangatho yamazwe ngamazwe: API 5L: isebenza kumbhobho we-piholi, icacisa ubungakanani be-pipe yentsimbi yentsimbi, ichaza ubungakanani bezenziweyo kunye nemveliso yokwenziwa kwemveliso yombhobho wentsimbi.
2. UMGAQO-NKQUBO WESIZWE: GB / T 9711: Esebenzayo kwi-pile yeShishini yeoyile kunye neBarrition Shishini, icacisa iimfuno zobugcisa ze-spiral pipe yentsimbi. I-GB / T 3091: isebenza kumbhobho wentsimbi ye-welded yothutho olusezantsi lokuhamba, icacisa ubungakanani kunye neemfuno zobugcisa zombhobho wentsimbi.
