Ububanzi obujwayelekile kanye nobubanzi bangaphakathi nangaphandle bepayipi lensimbi elijikelezayo

Ipayipi lensimbi elijikelezayouhlobo lwepayipi lensimbi elenziwe ngokugoqa umucu wensimbi ube yisimo sepayipi nge-engeli ethile ejikelezayo (i-engeli yokwakha) bese uyishisela. Isetshenziswa kabanzi ezinhlelweni zamapayipi okudlulisa uwoyela, igesi yemvelo kanye namanzi.

Ububanzi obujwayelekile buyi-diameter ejwayelekile yepayipi, inani elijwayelekile lobukhulu bepayipi. Kupayipi lensimbi elijikelezayo, ububanzi obujwayelekile buvame ukusondela, kodwa abulingani, nobubanzi bangempela bangaphakathi noma bangaphandle.

Ngokuvamile ivezwa yi-DN kanye nenombolo, njenge-DN200, ekhombisa ipayipi lensimbi elinobubanzi obungu-200 mm.

Ububanzi obujwayelekile bobubanzi obujwayelekile (i-DN):
1. Ububanzi obuncane (DN100 - DN300):
DN100 (amasentimitha angu-4)

2. Ububanzi obuphakathi nendawo (DN350 - DN700):
I-DN350 (amasentimitha angu-14)
I-DN400 (amasentimitha angu-16)
I-DN450 (amasentimitha angu-18)
I-DN500 (amasentimitha angu-20)
I-DN600 (amasentimitha angu-24)
I-DN700 (amasentimitha angu-28)

3. Ububanzi obukhulu (DN750 - DN1200)
DN750 (amasentimitha angu-30)
I-DN800 (amasentimitha angu-32)
I-DN900 (amasentimitha angu-36)
DN1000 (amasentimitha angu-40)
I-DN1100 (amasentimitha angu-44)
I-DN1200 (amasentimitha angu-48)

4. Ububanzi obukhulu kakhulu (DN1300 nangaphezulu)
I-DN1300 (amasentimitha angu-52)
I-DN1400 (amasentimitha angu-56)
DN1500 (amasentimitha angu-60)
I-DN1600 (amasentimitha angu-64)
I-DN1800 (amasentimitha angu-72)
I-DN2000 (amasentimitha angu-80)
I-DN2200 (amasentimitha angu-88)
I-DN2400 (amasentimitha angu-96)
I-DN2600 (amasentimitha angu-104)
I-DN2800 (amasentimitha angu-112)
I-DN3000 (amasentimitha angu-120)

Ububanzi bangaphandle (OD): I-OD ububanzi bomphezulu wangaphandle wepayipi lensimbi elijikelezayo. I-OD yepayipi lensimbi elijikelezayo ubukhulu bangempela bangaphandle kwepayipi. I-OD ingatholakala ngokulinganisa kwangempela, ngokuvamile ngamamilimitha (mm).
Ububanzi Bangaphakathi (ID): I-ID ububanzi bobuso bangaphakathi bepayipi lensimbi elijikelezayo. I-ID ubukhulu bangempela bangaphakathi lepayipi. I-ID ivame ukubalwa ngokukhipha kabili ubukhulu bodonga ku-OD ngamamilimitha (mm) I-ID = OD-2 x Ubukhulu Bodonga

Inkambu yohlelo lokusebenza

Amapayipi ensimbi ajikelezayo anobubanzi obuhlukile anezinhlelo zokusebenza ezahlukene emikhakheni ehlukahlukene:
1. ububanzi obuncaneIpayipi Lensimbi LaseSsaw(DN100 - DN300): isetshenziswa kakhulu kwezobunjiniyela bomasipala kumapayipi okuhambisa amanzi, amapayipi okukhipha amanzi, amapayipi egesi, njll.
2. ububanzi obuphakathiIpayipi le-Ssaw(DN350 - DN700): isetshenziswa kabanzi kumapayipi kawoyela, igesi yemvelo kanye nepayipi lamanzi lezimboni. 3. ipayipi lensimbi elijikelezayo elinobubanzi obukhulu (DN100 - DN300): livame ukusetshenziswa kumapayipi okuhambisa amanzi obunjiniyela bomasipala, amapayipi okukhipha amanzi, amapayipi egesi, njll.
3.Ipayipi le-Ssaw elinobubanzi obukhulu(DN750 - DN1200): isetshenziswa kumaphrojekthi okudlulisa amanzi amabanga amade, amapayipi kawoyela, amaphrojekthi amakhulu ezimboni, njengokuthutha okuphakathi nendawo.
4. ububanzi obukhulu kakhuluIpayipi Lensimbi Yekhabhoni Le-Ssaw(DN1300 nangaphezulu): isetshenziswa kakhulu kumaphrojekthi amanzi, uwoyela negesi ahamba ibanga elide, amapayipi angaphansi kwamanzi kanye neminye imisebenzi yengqalasizinda emikhulu.

Ububanzi obujwayelekile kanye nezinye izici zepayipi lensimbi elijikelezayo zivame ukukhiqizwa ngokuhambisana nezindinganiso kanye nezincazelo ezifanele:
1. amazinga omhlaba wonke: I-API 5L: isebenza epayipini lensimbi lokuthuthwa kwamapayipi, icacisa usayizi nezidingo zezinto ezibonakalayo zepayipi lensimbi elijikelezayo i-ASTM A252: isebenza epayipini lensimbi lesakhiwo, icacisa usayizi nezidingo zokukhiqiza zepayipi lensimbi elijikelezayo.
2. indinganiso kazwelonke: GB/T 9711: isebenza epayipini lensimbi lokuthuthwa kwemboni kawoyela negesi, icacisa izidingo zobuchwepheshe zepayipi lensimbi elijikelezayo. gb/t 3091: isebenza epayipini lensimbi elihlanganisiwe lokuthuthwa koketshezi olunomfutho ophansi, icacisa ubukhulu kanye nezidingo zobuchwepheshe zepayipi lensimbi elijikelezayo.
