Thupi Lopanga Zitsulo, Vavu Yampira Wamphamvu Yamafuta, Gasi & Chemical

Zimabwera ndi mapeto a flange. Ndicho chifukwa chake mainjiniya ndi oyang'anira zomera nthawi zambiri amasankha mizere yovuta kwambiri - ndiyosavuta kuyiyika pamalopo, yosavuta kusamalira, ndipo cholumikizira cha flange chimakhala ndi chisindikizo chodalirika.

Makhalidwe Ofunika

Forged Steel Body Construction

Thupi lathu lopangidwa ndi valavu yopangidwa ndi flanged mpira limapangidwa kuchokera ku solid steel billet kudzera mu forging, osati kuponya mchenga. Njira yopangira zitsulo imayeretsa mkati mwa njere zachitsulo, kuchotsa zolakwika zodziwika bwino monga porosity, shrinkage cavities ndi inclusions mchenga. Izi zimapereka thupi la vavu kuti likhale lolimba kwambiri, kukana mphamvu komanso kukana kugwedezeka kwamphamvu.

Ma valve otayira amagwira ntchito bwino pamapaipi wamba, omwe ali pachiwopsezo chochepa. Koma pakupanikizika kwambiri, kunyamula katundu wozungulira komanso ntchito yofunika kwambiri pachitetezo, zomangamanga zomanga zimachepetsa kwambiri chiwopsezo cha kuwonongeka kwa thupi komanso kutayikira koopsa. Kupanga kulikonse kwaiwisi kumatha kutsatiridwa ndi manambala a kutentha kwakuthupi, ndipo ziphaso zonse zoyeserera (MTC) zimapezeka mukafunsidwa.

Ndi mafakitale ndi ma TV ati omwe amagwirizana ndi valavu iyi ya mpira?

Valavu yopangidwa ndi flanged iyi imatengedwa kwambiri pamafuta & gasi, kutumiza kwa gasi, kukonza mankhwala, zoyenga, zopangira magetsi, mapaipi othandizira akunyanja, makina ojambulira madzi oponderezedwa kwambiri ndi mafakitale a feteleza.

Zimagwira ntchito modalirika pazamadzimadzi zoyera, mpweya woponderezedwa, gasi wachilengedwe, nayitrogeni, hydrocarbon ndi mitundu yosiyanasiyana yamadzimadzi osawononga. Ndi kusankha koyenera ndi mipando, imathanso kuthana ndi media zowononga pang'ono. Amapangidwira ntchito yodzipatula, yabwino kwa mapaipi omwe amafunikira kuzimitsidwa koyenera panthawi yokonza kapena kuzimitsa mwadzidzidzi.

Flanged Connection Design

Kulumikizana kwa Flanged ndiye chisankho chachikulu pama projekiti olemetsa kwambiri. Nkhope yokhazikika ya flange (RF / RTJ yosankha) imagwirizana ndi ASME B16.5 kapena GB flange miyezo. Pakuyika, ogwira nawo ntchito amatha kulumikiza mabowo a bawuti mosavuta, kuyika ma gaskets ndikumangitsa mabawuti popanda zida zapadera zowotcherera.

Phindu lalikulu limabwera pakukonzanso: mutha kutulutsa valavu ku payipi mwachangu popanda kudula chitoliro. Izi zimachepetsa kwambiri nthawi yopuma mukafunika kuyang'ana zamkati, kusintha mipando kapena kusintha valve yonse. Poyerekeza ndi malekezero a ulusi, zolumikizira za flanged zimathandizira kukakamiza kwakukulu; poyerekeza ndi malekezero welded, chimathandiza repeatable disassembly.

Kodi valavu yampira iyi imatha kuthana ndi kutentha pafupipafupi komanso kusinthasintha kwamphamvu?

Mapaipi akumafakitale nthawi zambiri amawona kusintha kwa kuthamanga kwa ntchito ndi kutentha panthawi yoyambira, kutseka ndi kusintha kwa katundu. Thupi lachitsulo lopangidwa ndi chitsulo limasunga magwiridwe antchito okhazikika pansi pamikhalidwe yozungulira iyi.

Timagwirizanitsa phukusi losindikizira ndi envulopu yanu yogwira ntchito. PTFE, RPTFE ndi zitsulo-to-metal hard seal options zilipo. Mipando yofewa imapereka zero-kudontha kuwira kothina kotseka kwa ntchito yoyera; mipando yachitsulo imagwirizana ndi kutentha kwakukulu kapena zofunikira zotetezera moto. Mapangidwe onyamula tsinde amawongolera mpweya wothawa, kukwaniritsa zofunikira za chilengedwe pa ntchito ya hydrocarbon.

Zosankha Zazida Zathupi & Kuchepetsa Kwamkati

Timakhala ndi mbiri yotakata kuti ifanane ndi dzimbiri lanu lapakati komanso kutentha komwe mukufuna:

- Chitsulo cha kaboni: A105 / A105N, yabwino kwa gasi wosawononga kwambiri komanso mafuta

- Chitsulo chosapanga dzimbiri cha Austenitic: F304, F316L, chamadzimadzi ambiri owononga

- Duplex & super duplex: F51, F53, F57, NS2609, NS2607 yamadzi am'nyanja, brine ndi ma acidic media okhala ndi H₂S

Tikhozanso makonda mpira, tsinde ndi mipando mipando. Ingogawanani zapakati, mtengo wa pH ndi kuchuluka kwa kutentha komwe mukugwirira ntchito, ndipo gulu lathu la uinjiniya lidzakulangizani zosakaniza zotsika mtengo kwambiri.

Kukula, Gulu la Pressure & Mapangidwe Osankha

Kukula kumaphimba DN15 ~ DN300 ndi kubereka kokulirapo pakufuna. Kupanikizika kumaphatikizapo PN16, PN40, PN63, PN100, PN160, komanso ASME Class 150, 300, 600, 900, 1500.

Nkhope za Flange zimapezeka mu Raised Face (RF) ndi Ring Type Joint (RTJ). Mapangidwe otetezedwa ndi moto komanso odana ndi static atha kuperekedwa popempha.

Mutha kusankha bore wathunthu kapena wocheperako. Full bore mabala otaya kutaya ndi kulola nkhumba. Kubowola kocheperako kumakhala kocheperako komanso kosavuta ngati nkhumba sikufunika.

Zosankha za Opaleshoni

Timapereka masitaelo angapo a actuation kuti agwirizane ndi zosowa za tsamba lanu:

- Chogwirizira cha Lever: chotsika mtengo komanso chosavuta, choyenera kugwiritsa ntchito pamanja pomwe valavu ndiyosavuta kufikako

- Ogwiritsa ntchito magiya: kwa ma valve akulu oboola kapena okwera kwambiri, kumapangitsa kutsegula ndi kutseka kosavuta

- Pneumatic actuator: tsegulani mwachangu ndikutseka. Imaphatikizana ndi ma valve a solenoid ndikusintha ma switch kuti aziwongolera zokha

- Choyatsira magetsi: choyenera kugwira ntchito patali, kuyendetsa bwino, kapena malo opanda mpweya woponderezedwa

Tikhozanso kuwonjezera gudumu lamanja ku ma valve oyendetsa. Izi zimakulolani kuti mugwiritse ntchito valavu pamanja ngati mphamvu kapena mpweya walephera.

Ndi miyezo yotani yoyendera ndi zolemba zomwe mungapeze kwa ife?

Vavu iliyonse yopangidwa mwachinyengo imayesedwa movomerezedwa ndi chipolopolo cha hydrostatic ndikuyezetsa kutayikira kwa mipando isanalongedwe. Timatsatira API 6D, ASME B16.5 ndi miyezo yokhudzana ndi mafakitale. Kuyendera kwa mboni za gulu lachitatu kumathandizidwa ngati kufunidwa ndi zomwe polojekiti yanu ikufuna.

Titha kukupatsirani zikalata zonse zomwe mungafune: ziphaso zoyezetsa zakuthupi, malipoti oyesa, zojambula zamitundu ndi zolemba zogwirira ntchito. Valavu iliyonse imasindikizidwa momveka bwino ndi nambala yake ya kutentha, kalasi yazinthu, kukula kwake ndi kupanikizika, kuti muthe kufufuza mbiri yake yazinthu ndi kupanga popanda vuto.
