Umehluko Obalulekile Phakathi kwe-DN ne-ANSI Flanges

Ama-Flange ayingxenye ebalulekile ezinhlelweni zamapayipi, esetshenziswa ukuhlanganisa amapayipi, ama-valve, amaphampu, nezinye izinto zokusebenza. Lapho ukhetha ama-flanges, kufanele kubhekwe izindinganiso ezimbili eziyinhloko – DN (I-Dimension Nominal) kanye ne-ANSI (I-American National Standards Institute). Nakuba kokubili kuvamile, kunomehluko obalulekile okufanele uwuqonde lapho ukhetha phakathi kwama-flange e-DN vs ANSI. Lesi sihloko sizoqhathanisa i-dn vs ansi flanges ngokuningiliziwe ukukusiza wenze ukukhetha okufanele.

Isingeniso

Ama-flange ahlinzeka ngendlela yokuxhuma amapayipi kanye nokudlulisa uketshezi noma amagesi ngokubopha kanye nama-gaskets phakathi kwawo ukuze kuvalwe uxhumano.. Zisetshenziswa ezinhlelweni eziningi ezivela embonini kawoyela negesi kuya ekucutshungulweni kokudla nesiphuzo, izitshalo zamandla, futhi nokuningi.

Kunezindinganiso ezimbili eziyinhloko zamazwe ngamazwe zobukhulu be-flange nezilinganiso:

• DN – I-Dimensional Nominal (I-European/ISO standard)
• I-ANSI – I-American National Standards Institute (Izinga laseMelika)

Nakuba bobabili belandela isimiso sokuklama esifanayo, kukhona ukuhlukahluka kobukhulu, izilinganiso zokucindezela, ezibhekene, namaphethini omshudo awenza angashintshani. Ukuqonda i-dn vs ansi flanges kuzoqinisekisa ukuthi ukhetha ama-flange alungile wesistimu yakho yamapayipi.

Umehluko Obalulekile Phakathi kwe-DN ne-ANSI Flanges

Lapho kuhlolwa i-dn vs ansi flanges, okulandelayo yizici eziyinhloko okufanele uziqhathanise:

Ubukhulu

• Ama-DN flange asekelwe kumasayizi amapayipi okuzisholo anokwenyuswa kobubanzi obuvamile.
• Amaflange e-ANSI anobukhulu obuyintshi obujwayelekile obungahlobene ngokuqondile nosayizi wepayipi.

Lokhu kusho ukuthi i-DN 100 i-flange iqondana nepayipi elingu-100mm, kuyilapho i-ANSI 4” flange ine-bore of approx. 4.5”. Ama-DN flange asebenzisa amamethrikhi kuyilapho i-ANSI isebenzisa amayunithi ombuso.

Izilinganiso Zokucindezela

• Ama-DN flange asebenzisa isilinganiso se-PN – ukucindezela okukhulu ku-BAR ngezinga lokushisa elinikeziwe.
• Ama-ANSI flange asebenzisa Isilinganiso Sekilasi – ingcindezi ephezulu ye-psi esekelwe kumandla wezinto ezibonakalayo.

Ngokwesibonelo, i-DN150 PN16 flange = ANSI 6” 150# i-flange emandleni okuphatha ingcindezi.

Izitayela Ezibhekene

• Ama-DN flange asebenzisa ama-faces eFomu B1 noma i-B2.
• Ama-ANSI ama-flange asebenzisa ubuso obuphakamisiwe (I-RF) noma Ubuso Obucaba (FF) ezibhekene.

I-B1 ifana ne-RF, kuyilapho i-B2 iqhathaniswa ne-FF. Ubuso kufanele bufane ukuze kuvalwe uphawu ngendlela efanele.

Imibuthano ye-Bolt

• Izimbobo ze-bolt ze-DN zitholakala ngokusekelwe kububanzi obuzisholo.
• Imibuthano yebhawudi ye-ANSI isuselwe esilinganisweni sesigaba se-flange.

Izimbobo ze-bolt ngeke ziqondanise phakathi kwezitayela ezimbili.

Izinto zokwakha

• Ama-DN flange asebenzisa izinto ezisekelwe kumethrikhi – P250GH, 1.4408, njll.
• I-ANSI isebenzisa amamaki e-imperial/US – A105, I-A182 F316L, njll.

Okubalulekile kufanele kulingane nokusingatha amazinga okushisa adingekayo nezingcindezi.

Njengoba ubona, dn vs ansi flanges anomehluko omncane impela owenza angashintsheki. Ukuxuba kokubili kuvame ukuholela ekuvuzeni, umonakalo, nezinye izindaba.
