Phapang ea Bohlokoa lipakeng tsa DN le ANSI Flanges

Li-flanges ke karolo ea bohlokoa tsamaisong ea liphaephe, se sebedisoang ho kopanya diphaephe, li-valve, lipompo, le lisebelisoa tse ling. Ha u khetha li-flanges, litekanyetso tse peli tse ka sehloohong li tlameha ho nkoa – DN (Dimension Nominal) le ANSI (Setsi sa Maemo a Naha sa Amerika). Le hoja ka bobeli li tloaelehile, ho na le liphapang tsa bohlokoa tseo u lokelang ho li utloisisa ha u khetha pakeng tsa DN vs ANSI flanges. Sengoliloeng sena se tla bapisa dn vs ansi flanges ka botlalo ho u thusa ho etsa khetho e nepahetseng.

Li-flanges li fana ka mokhoa oa ho hokahanya liphaephe le ho fetisa maro kapa likhase ka ho bolt hammoho le likhase pakeng tsa tsona ho tiisa khokahano.. Li sebelisoa lits'ebetsong tse ngata ho tloha indastering ea oli le khase ho ea ho phepelo ea lijo le lino, limela tsa motlakase, le ho feta.

Ho na le litekanyetso tse peli tsa mantlha tsa machaba bakeng sa litekanyo tsa flange le litekanyetso:

Phapang e ka Sehloohong Pakeng tsa DN le ANSI Flanges

Ha u lekola dn vs ansi flanges, tse latelang ke lintlha tse ka sehloohong ho bapisa:

Litekanyo

• Li-flange tsa DN li ipapisitse le boholo ba liphaephe tse nang le li-increments tse tloaelehileng tsa bophara.
• Li-flange tsa ANSI li na le litekanyo tse tloaelehileng tsa inch tse sa amaneng ka kotloloho le boholo ba liphaephe.

Sena se bolela DN 100 flange e tsamaisana le phala ea 100mm, ha ANSI 4 ”flange e na le bore ea hoo e ka bang. 4.5”. Li-flange tsa DN li sebelisa metrics ha ANSI e sebelisa li-unit tsa borena.

Khatello Ratings

• Li-flange tsa DN li sebelisa lintlha tsa PN – khatello e kholo ho BAR ka mocheso o fanoeng.
• Li-flange tsa ANSI li sebelisa lintlha tsa Sehlopha – khatello e phahameng ea psi e thehiloeng matla a lintho tse bonahalang.

Ka mohlala, DN150 PN16 flange = ANSI 6” 150# flange bokgoning ba ho sebetsana le kgatello.

Litaele Tsa ho Tobana

• Li-flange tsa DN li sebelisa lifahleho tsa Foromo ea B1 kapa B2.
• Li-flange tsa ANSI li sebelisa sefahleho se phahamisitsoeng (RF) kapa Sefahleho se Sephara (FF) tse shebaneng.

B1 e tšoana le RF, ha B2 e bapisoa le FF. Sefahleho se tlameha ho lumellana le ho tiisa hantle.

Bolt Circles

• Likoti tsa bolt tsa DN li fumaneha ho latela bophara ba lebitso.
• Li-circles tsa bolt tsa ANSI li ipapisitse le maemo a sehlopha sa flange.

Likoti tsa bolt li ke ke tsa lumellana pakeng tsa mekhoa e 'meli.

Lisebelisoa

• Li-flange tsa DN li sebelisa lisebelisoa tse thehiloeng ho metric – P250GH, 1.4408, etc.
• ANSI e sebelisa limaraka tsa boemphera/US – A105, A182 F316L, etc.

Thepa e tlameha ho lekana le mocheso o hlokahalang le likhatello.

Joalo ka ha u bona, dn vs ansi flanges li na le liphapang tse ngata tse etsang hore li se ke tsa fetoha. Ho kopanya tse peli hangata ho lebisa ho lutla, tshenyo, le litaba tse ling.
