I-Butt-Weld Neck Flanges

Ama-flange entamo ye-butt-weld aklanyelwe ukushisela ngqo ekupheleni kwepayipi noma umkhumbi. Zifaka intamo ende, ecijile esiza ukusabalalisa ingcindezi endaweni enkulu, okuzenza zilungele izinhlelo zokusebenza ezinomfutho ophezulu kanye nezinga lokushisa eliphezulu. Ukushintsha okushelelayo phakathi kwe-flange nepayipi kunciphisa ukuxokozela nokwehla kwengcindezi, okuqinisekisa ukuhlangana okuqinile, okungavuzi. Lawa ma-flange ngokuvamile enziwa ngezinto ezihlala isikhathi eside njenge-carbon steel, insimbi engagqwali, ne-alloy steel, enikeza ukumelana okuhle kakhulu nokugqwala nokuguga.

Ama-flange entamo ye-Butt-weld avame ukusetshenziswa ezimbonini ezifana nowoyela negesi, ukucubungula amakhemikhali, ukukhiqizwa kwamandla, nokwelashwa kwamanzi, lapho ukuxhumeka okuvikelekile, okusebenzayo kuyadingeka. I-flange ivamise ukushiselwa epayipini kusetshenziswa indlela ye-butt-weld, ehlinzeka ngoxhumano olungenamthungo, oluqinile olugcina ubuqotho besistimu yamapayipi. Kutholakala ngezilinganiso ezihlukene zokucindezela nosayizi, ama-flange entamo ye-butt-weld avumelana namazinga omkhakha afana ne-ASME B16.5, okuqinisekisa ukuhambisana nokuthembeka kuzo zonke izinhlelo zokusebenza ezihlukene.

I-Butt-Weld Neck Flanges Isicelo

Ama-flange entamo ye-butt-weld asetshenziswa kakhulu ezinhlelweni zamapayipi anengcindezi ephezulu kanye namazinga okushisa aphezulu, lapho amandla, ukuqina, nokusebenza kokuvikela ukuvuza kubalulekile. Lawa ma-flange asetshenziswa ngokuyinhloko ezimbonini ezifana nowoyela negesi, i-petrochemical, ukukhiqiza amandla, nokucubungula amakhemikhali, lapho asetshenziselwa ukuxhuma amapayipi, ama-valve, nemikhumbi yokucindezela ngokuphepha. Intamo ende, ecijile ye-flange isiza ukusabalalisa ingcindezi ngokulinganayo, iyenze ilungele izinhlelo zokusebenza ezibucayi ezidinga ukuxhumana okuhlala isikhathi eside, okuphezulu kobuqotho.

Emapayipini kawoyela negesi, ama-flange entamo ye-butt-weld asetshenziselwa ukuqinisekisa amalunga athembekile futhi aqinile angakwazi ukumelana nokucindezela okuphezulu nezimo ezinzima. Zibuye zisetshenziswe ngokujwayelekile emigqeni yesitimu, izishintshisi zokushisa, nama-reactors, lapho ukumelana nokucindezela nokuguquguquka kwezinga lokushisa kubalulekile. Ukwengeza, lawa ma-flange ancanyelwayo ezinhlelweni zokusebenza lapho ubuqotho besistimu nokugeleza okushelelayo kubalulekile, njengoba idizayini inciphisa isiyaluyalu nokwehla kwengcindezi.

Ama-butt-weld neck flange ajwayele ukushiselwa emapayipini kusetshenziswa inqubo yokushisela izinqe, ehlinzeka ngoxhumano olungenamthungo olungenayo imifantu, okunciphisa ubungozi bokuvuza noma ukugqwala ngokuhamba kwesikhathi.

Uyini umehluko phakathi kwama-weld neck flanges nama-slip-on flanges?

Umehluko oyinhloko phakathi weld neck flanges and ama-slip-on flanges ilele ekwakhiweni kwazo kanye nendlela ezixhunywe ngayo kwipayipi.

A weld intamo flange inentamo ende, ecijile eshiselwe epayipini. Lo mklamo uvumela ukuthi ukucindezeleka kusatshalaliswe kancane kancane kusuka kupayipi kuya ku-flange, okwenza kube kulungele izicelo zokucindezela okuphezulu nokushisa okuphezulu. I-weld eqhubekayo phakathi kwepayipi ne-flange inikeza uxhumano oluqinile, olungavuzi. Ama-Weld neck flanges avame ukusetshenziswa ezinhlelweni ezibucayi, njengakuwoyela negesi, ukucubungula amakhemikhali, kanye nezinhlelo zokuphehla amandla.

Ngakolunye uhlangothi, a i-slip-on flange yakhelwe ukuthi "ishelele" ekupheleni kwepayipi, bese ishiselwa kokubili ngaphakathi nangaphandle ukuze ivikeleke. Lolu hlobo lwe-flange lulula futhi luyashesha ukulufaka uma luqhathaniswa ne-weld neck flange futhi luvame ukusetshenziswa kumasistimu okucindezela okuphansi lapho uxhumano lungadingi ukumelana nengcindezi enkulu. Ama-slip-on flanges abiza kakhulu futhi avame ukutholakala emanzini, emoyeni, nasezinhlelweni zesitimu esinomfutho ophansi.

Kafushane, ama-weld neck flanges ahlala isikhathi eside futhi afaneleka kakhulu ezinhlelweni zokucindezela okuphezulu, kuyilapho ama-slip-on flange ebiza kakhulu futhi kulula ukuyifaka ezinhlelweni zokucindezela okuphansi.

Iyini i-buttweld flange?

A i-butt-weld flange iwuhlobo lwe-flange eklanyelwe ukushiselwa ngqo epayipini noma emkhunjini, okwenza uxhumano oluqinile, oluhlala njalo. I-flange inomphetho oyi-beveled ovumela ukuthi ipayipi lifakwe futhi lishiselwe nxazonke, okwenza ilunga elingenamthungo. Le nqubo yokushisela, eyaziwa ngokuthi i-butt welding, iqinisekisa uphawu olungavuzi futhi ilungele ukucindezela okuphezulu, izinga lokushisa eliphezulu, kanye nezicelo ezibucayi.

Ama-butt-weld flange avame ukusetshenziswa ezimbonini ezifana nowoyela negesi, i-petrochemical, ukukhiqiza amandla, kanye nokucubungula kwamakhemikhali, lapho ubuqotho besistimu bubalulekile. Ukuklanywa kwe-flange kuqeda isidingo sokuxhunywa kwe-bolt, kuhlinzeka ngokuhlanganyela okuhlanzekile, okuthembekile. Ukwakheka kwe-flange kusiza ukusabalalisa ingcindezi ngokulinganayo, okuzuzisa kakhulu amasistimu achayeke kungcindezi ephezulu noma amandla aguqukayo.

Atholakala ngosayizi abahlukahlukene, izilinganiso zokucindezela, nezinto zokwakha (okuhlanganisa i-carbon steel, insimbi engagqwali, nensimbi ye-alloy), ama-butt-weld flange alungele amasistimu adinga ukuqina, ukumelana nokugqwala, nokunakekelwa okuncane. Ikhono le-flange lokugcina indawo yangaphakathi ebushelelezi liqinisekisa ukugeleza okuncishisiwe, okuyenza ifanelekele izinhlelo zokuthutha uketshezi negesi.
