Weld Neck Flange

A weld khosi flangenthawi zambiri amasankhidwa pomwe kulumikizana kukuyembekezeka kunyamula zambiri kuposa kungokakamiza. Mu ntchito zenizeni, ogula amasankha izo chifukwakhola lopindika + matako{1}}khosiperekani kusinthasintha kwapang'onopang'ono kuchokera ku flange kupita ku chitoliro, chomwe chimathandizira pamakina owonekerakuthamanga panjinga, kusinthasintha kwa kutentha, kugwedezeka, kulemetsa-paipi yapakhoma, kapena kuwunika mozama.

Kugula, uku sikungosankha kalembedwe ka flange. Nthawi zambiri ndi chisankho chokhudzakudalirika, kulumikizana bwino, kukhazikika kwa weld, komanso kukhazikika kwanthawi yayitali-kwantchito. Weld neck flange yomwe ikugwirizana ndi zolondolamuyezo, kuyang'ana, kunyansidwa, ndandanda, ndi zinthunthawi zambiri imapanga zovuta zochepera-zochepera kuposa flange yosankhidwa ndi kukula kwadzina ndi kalasi.

Pamene ogula amafufuzaweld khosi flange specificationskapenaweld khosi flange muyezo, nthawi zambiri samangoyang'ana kuti awone ngati katunduyo ali m'gulu. Chomwe amafunikira kutsimikizira ndikuti ngati flange ikugwirizana ndikalasi ya mzere wa polojekiti, ndandanda ya chitoliro, mtundu woyang'ana, kalasi yazinthu, ndi kukula kwakezafotokozedwa kale muzojambula kapena PO. Pogula zenizeni, mavuto ambiri samachokera ku "no supply" - amachokera kuzinthu zomwe sizinatsekedwe koyambirira, monga bobo lolakwika la khoma la chitoliro, kuyang'ana kolakwika, kapena zofunikira za chikalata zomwe zimachepetsa kuvomereza ndi kuyika.

Kufotokozera koyenera kogula kuyenera kutanthauzira flange kudzera muzofufuza izi:

Mzere wamphamvu wa RFQ nthawi zambiri umalembedwa motere:

ASME B16.5, weld khosi flange, NPS 4, Kalasi 600, RF, ASTM A105, anabala Sch 80 chitoliro, MTR chofunika, Qty ___

Izi ndizotetezeka kuposa kungolemba "4 inch weld neck flange," chifukwa imawongolera mfundo zomwe nthawi zambiri zimayambitsa mikangano:kuyang'ana, kufananiza, zinthu,ndizolemba zolemba.

A weld khosi flangekawirikawiri amasankhidwa pamene mzere ukuyembekezeredwa kugwirakuthamanga kwambiri, kutentha kwapamwamba, kubwerezakutentha njinga, vibration, kapenacholemera-paipi yapakhomakumene kudalirika kwa mgwirizano kumafunika kwambiri kuposa kupanga zosavuta. M'mapulojekiti enieni, amagwiritsidwa ntchito kwambiri pamizere yotumizira mafuta ndi gasi, mapaipi oyeretsera ndi a petrochemical, ma module akunyanja, ma boiler, zolumikizira-zolumikizira ziwiya, ntchito za nthunzi, ndi njira zina zofunika kwambiri.

M'mautumiki awa, flange simalo olumikizirana. Zimakhudza mwachindunji:

• kutumiza katundu
• weld umphumphu
• nthawi-yaitalikusindikiza kukhazikika

Kuchokera pakuwona kwa wogula, mtengo wa weld neck flange umamveka bwino pamene mtengo wolephera uli wapamwamba. Kuwotchera pa-nthambi yopanikizika kwambiri, kukonzanso mobwerezabwereza chifukwa cha kusalongosoka bwino, kapena kukonza zowotcherera panthawi yokwanira-kutha kuwononga ndalama zambiri kuposa flange yokha.

Ubwino wake waukulu umachokera kutapered hubndibutt{{0}khosi lolowetsedwa, zomwe zimathandiza kupanga kusintha kosavuta pakati pa flange ndi chitoliro. M'mawu othandiza, izi zikutanthauza:

• bwinoadagwirizana
• kusintha pang'ono kwadzidzidzi pagawo la weld
• kukwanira bwino kwautumiki wa cyclicndikugwedera-mizere yovutirapo
• mwayi wowotcherera bwino kuti awunikenso
• odalirika kwambirikufufuza kwa radiographic
• wamphamvuchitoliro-ku-kupitilirabe

Ichi ndichifukwa chake mainjiniya amakonda ma weld neck flanges kuti apange mapaipi ovuta kwambiri pomwe kukhulupirika kwa nthawi yayitali kumafunika kuposa kuthamanga kwanthawi yayitali.

Kusankha kwazinthu kuyenera kutsata momwe ntchito ikuyendera, osati katundu kapena mtengo wokha. Kwa ma weld khosi ma flanges, zinthuzo zimafunika kuti zigwirizane ndi kalasi ya chitoliro, kutentha kwapangidwe, chilengedwe cha dzimbiri, ndi kuwunika kwa polojekiti / zolemba. Flange ikhoza kukhala yolondola, koma ngati zinthuzo sizikugwirizana ndi gulu la mzere, ndi chinthu chokanidwabe.

Mwambiri,Chithunzi cha ASTM A105amagwiritsidwa ntchito muyezo mpweya zitsulo mapaipi pansi zinthu wamba utumiki.Chithunzi cha ASTM A350 LF2imakonda kukhala-zotentha zotsika pomwe zimafunikira mphamvu. Pakutentha kwapamwamba-paipi ya alloy, ogula nthawi zambiri amatchulaF11, F22, kapena F91kuti mukhale ogwirizana ndi zida za chitoliro ndi momwe zimagwirira ntchito. Mu service yowononga,F304 / F316ndi wamba zosapanga dzimbiri options, pameneduplex / super duplexmagiredi ndi abwino kwambiri pamene zonse ziwiri za kukana kwa kloridi ndi mphamvu zapamwamba zimafunikira. PaOctal Pipe, mtundu uwu wa zinthu zofananira ndi imodzi mwa mfundo zowongolera mu mawu a flange ndikuwunikanso dongosolo, chifukwa kalasi yazinthu imakhudza mwachindunji kuvomera, kuyanjana kwa kuwotcherera, komanso kudalirika komaliza kwautumiki.

Chitsanzo chosavuta: pa mzere wa nthunzi, kusankha kwa flange sikungofanana kukula ndi kalasi - zinthuzi zimayeneranso kukhala zokhazikika pakutentha, kotero magiredi aloyi ngatiF11kapenaF22angafunike m'malo mwa carbon steel. Pamzere wotsika-wotentha, pogwiritsa ntchitoA105m'malo mwaLF2zitha kukhala pachiwopsezo cholimba ngakhale onsewo ali ndi magiredi opangira zitsulo za carbon. Pankhani yogula zinthu, zinthu zolakwika nthawi zambiri zimabweretsa mavuto akulu kuposa mtundu wolakwika wa flange, chifukwa zimakhudza kuvomereza, kuyanjana ndi kuwotcherera, komanso kuvomereza komaliza kwa polojekiti.

Mwachidule, ogula nthawi zambiri amasamukiraweld neck flange vs slip-pakusankha pamene dongosolo limakhala lovuta kwambiri ndipo chiopsezo cha kutayikira, kutopa, kapena kukonza mobwerezabwereza kumakhala kovuta kunyalanyaza.

Theweld khosi flange chizindikirondizofunika pazojambula, ma BOM, ndi ma RFQ chifukwa zolakwika zambiri za mawu zimayamba ndi mawu osamveka bwino kapena osakwanira.

Mfundo yonse yopangira khosi la weld ndikupanga kusintha kosalala kuchokera ku flange hub kupita ku khoma la chitoliro. Ngati chowotchereracho chili chocheperako, chokulirapo, kapena chikungofanana ndi ndandanda yolakwika, wowotcherera amakankhidwira ntchito yokonza m'munda monga.kugaya mkati, kusanja bwino,-kusintha kochepa, kapena kubweza mbiri ya weld. Izi sizimangokwanira pang'onopang'ono-m'mwamba - zimathanso kukhudza kusasinthika kwa weld, kuvomereza kwa radiographic, komanso njira yomaliza yolumikizirana.

Pa dongosolo lalikulu la weld neck flange, ogula nthawi zambiri amasamala kwambirizoyezeka zovomerezekakusiyana ndi mawu wamba monga "kulondola kwambiri."

Kuwunika kothandiza nthawi zambiri kumaphatikizapo:

• flange muyezo ndi kutsimikizira kalasi
• kuyang'ana mtundu cheke (RF / RTJ / FF)
• bore ndi hub miyeso
• bwalo la bawuti ndi kulondola kwa dzenje la bawuti
• serration kumaliza kapena RTJ groove kutsimikizira
• chizindikiro chotsimikizira
• kutentha nambala traceability kuti MTR
• PMI / UT / MT / PT pomwe pakufunika

Wowotcherera khosi flange yemwe amawoneka bwino atha kupangitsa kuchedwa kwatsamba ngatizokopa, zoyang'ana, kapena zolembamusagwirizane ndi zofunikira za polojekiti.
