Ububanzi okuzisholo kanye nobubanzi bangaphakathi nangaphandle kwepayipi lensimbi elivunguzayo

Ipayipi lensimbi elivunguzayoiwuhlobo lwepayipi lensimbi elenziwe ngokugoqa umucu wensimbi ube yisimo sepayipi endaweni ethile ezungezayo (i-engeli yokwakha) bese uyalishisela. Isetshenziswa kakhulu ezinhlelweni zamapayipi uwoyela, igesi yemvelo kanye nokudluliswa kwamanzi.

I-diameter yegama ububanzi obujwayelekile bepayipi, inani elincane losayizi wepayipi. Ngepayipi lensimbi elivunguzayo, ububanzi obujwayelekile buvame ukusondele, kodwa abulingani, nobubanzi bangempela bangaphakathi noma bangaphandle.

Ivamise ukuvezwa yi-DN kanye nenombolo, efana ne-DN200, ekhombisa ipayipi lensimbi elinobubanzi obungu-200 mm.

Ububanzi obujwayelekile be-nominal (DN):
1. Ibanga lobubanzi obuncane (DN100 - DN300):
I-DN100 (4 amayintshi)
DN150 (6 amayintshi)
I-DN200 (8 amayintshi)
I-DN250 (10 amayintshi)
I-DN300 (12 amayintshi)

2. Ibanga lobubanzi obumaphakathi (DN350 - DN700):
I-DN350 (14 amayintshi)
I-DN400 (16 amayintshi)
I-DN450 (18 amayintshi)
I-DN500 (20 amayintshi)
I-DN600 (24 amayintshi)
I-DN700 (28 amayintshi)

3. Ububanzi Olukhulu Lobubanzi (DN750 - DN1200)
I-DN750 (30 amayintshi)
I-DN800 (32 amayintshi)
I-DN900 (36 amayintshi)
I-DN1000 (40 amayintshi)
I-DN1100 (44 amayintshi)
I-DN1200 (48 amayintshi)

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

Ububanzi bangaphandle (OD): I-OD ububanzi bendawo yangaphandle yepayipi lensimbi elivunguzayo. I-OD yepayipi lensimbi elivunguzayo ubukhulu bangempela bangaphandle kwepayipi. I-OD ingatholwa ngesilinganiso sangempela, ngokuvamile ngamamilimitha (mm).
Ububanzi Bangaphakathi (ID): I-ID ububanzi bendawo engaphakathi yepayipi lensimbi elisontekile. I-ID ingusayizi wangempela wengaphakathi lepayipi. I-ID ivamise ukubalwa ngokukhipha ukujiya kabili kodonga ku-OD ngamamilimitha (mm) ID = OD-2 x Ukuqina Kodonga

Inkambu yohlelo lokusebenza

Amapayipi ensimbi okuvunguza anamadayamitha ahlukene okuzisholo anemisebenzi ehlukene emikhakheni ehlukahlukene:
1. ububanzi obuncaneIpayipi lensimbi ye-Ssaw(DN100 - DN300): evame ukusetshenziswa kunjiniyela kamasipala amapayipi amanzi, amapayipi amanzi, amapayipi igesi, njll.
2. ububanzi obuphakathiI-Ssaw Pipe(DN350 - DN700): isetshenziswa kabanzi kuwoyela, ipayipi legesi yemvelo kanye nepayipi lamanzi lezimboni. 3. ipayipi elikhulu lensimbi elivunguzayo (DN100 - DN300): elivame ukusetshenziswa epayipini lokuphakelwa kwamanzi lobunjiniyela bakamasipala, ipayipi lokudonsa amanzi, ipayipi legesi, njll.
3.Ipayipi elikhulu le-Diameter Ssaw(DN750 - DN1200): isetshenziswa kumaphrojekthi okuhambisa amanzi amabanga amade, amapayipi kawoyela, amaphrojekthi amakhulu ezimboni, njengokuhamba okuphakathi.
4. Ububanzi obukhulu kakhuluIpayipi lensimbi ye-Ssaw Carbon(I-DN1300 nangaphezulu): isetshenziselwa ikakhulukazi amaphrojekthi amabanga amade wamanzi ahamba ibanga elide, kawoyela negesi, amapayipi ahamba ngaphansi kolwandle kanye neminye imiklamo yengqalasizinda emikhulu.

Ububanzi obujwayelekile kanye nokunye okucacisiwe kwepayipi lensimbi elivunguzayo kuvame ukukhiqizwa ngokuhambisana namazinga afanele kanye nokucaciswa:
1. izindinganiso zamazwe ngamazwe: I-API 5L: esebenza epayipini lensimbi lokuthutha, icacisa usayizi nezidingo zempahla yepayipi lensimbi elivunguzayo i-ASTM A252: esebenza epayipini lensimbi yesakhiwo, icacisa usayizi kanye nezidingo zokukhiqiza zepayipi lensimbi elivunguzayo.
2. Izinga likazwelonke: I-GB/T 9711: esebenza epayipini lensimbi lokuthuthwa kwemboni kawoyela negesi, icacisa izidingo zobuchwepheshe zepayipi lensimbi elivunguzayo. I-gb/t 3091: esebenza epayipini lensimbi elishiselwe ukuthutha uketshezi olunomfutho ophansi, icacisa ubukhulu nezidingo zobuchwepheshe zepayipi lensimbi elivunguzayo.
