Khoom Description
Cam khwb cia los ntawm QT450-10 ductile hlau, qhov no DN100 × 80 ob flanged taper conforms rau EN545 thiab ISO2531 qauv. Tsim nrog flanges ntawm ob qhov kawg, nws hloov txoj kab uas hla ntawm DN100 mus rau DN80, xa cov dej ntws zoo thiab txo cov dej turbulence thiab poob taub hau.
Ob lub flanges tso cai rau kev sib txuas ncaj qha rau cov kav dej lossis cov li qub, ua kom yooj yim sib dhos, disassembly thiab yooj yim txij nkawm tom qab.

Qhov zoo
Ob-kawg flanges yog tsim nyob rau hauv ib tug casting khiav. Zero welding seams muaj nyob rau ntawm tag nrho ib feem, uas nteg lub hauv paus zoo rau txhim khu kev qha sealing kev ua tau zoo.
QT450-10 cov khoom siv hlau ua kom muaj zog zoo. Nws tuaj yeem sawv hauv av hloov chaw thiab sab nraud vibration loads. Lub caij nyoog ntawm tawg tiam thiab nruab nrab to tau qis heev.
Phab ntsa tuab ua kom zoo ib yam thoob plaws lub cev reducer. Nws tuav lub peev xwm ua kom lub siab ruaj khov, thiab yuav tsis yooj yim deform txawm tias ua haujlwm nyob rau hauv qhov chaw kub kub lossis qhov kub qis.
Kev teeb tsa ntawm DN100 × 80 Ob Chav Flanged Taper
Cais & depressurize pipeline ua ntej ua hauj lwm. Tshawb xyuas reducer, flanges, gasket thiab bolts rau kev puas tsuaj. Ntxuav tag nrho flange sealing ntsej muag.
Loj dua flange DN100 txuas mus rau upstream DN100 yeeb nkab; me flange DN80 txuas mus rau downstream DN80 yeeb nkab. Khaws coaxial sib dhos.
Muab gasket concentrically ntawm flange ntsej muag. Ntxig tag nrho cov ntsia hlau thiab tuav tes- nruj.
Torque bolts nyob rau hauv crisscross / hnub qub sib lawv liag, nyob rau hauv 3 kis: 30% → 60% → 100% ntawm kawg torque tus nqi.
Txhawb cov kav dej kom zoo, tsis txhob cia flange sib koom ua ke nqa cov yeeb nkab thauj khoom.
Ua qhov ntsuas hydrostatic siab. Tshawb xyuas flange cov pob qij txha kom to.
Tsis txhob zawm bolts nyob rau hauv siab. Hloov gasket yog tias muaj dej ntws tawm.
Cov yam ntxwv zoo
Qhov no DN100 × 80 ob flanged taper nta ib qho concentric tapered puab bore, uas xyuas kom meej maj mam thiab du txoj kab uas hla.
Lub cev tapered yog cam khwb cia li ib thooj, khoom qauv nrog zoo rigidity nyob rau hauv pipeline siab.
Uniform phab ntsa thickness tsim kom txo cov kev ntxhov siab thaum lub sij hawm thauj cov dej.
Flange lub ntsej muag yog machined kom zoo los lav nruj sealing nrog gaskets.
Kev tu
Kev soj ntsuam niaj hnub
Txheeb xyuas epoxy / FBE txheej sab nraud rau chipping, tawg thiab xeb. Tshawb xyuas flange cov pob qij txha kom to. Tshawb xyuas galvanized bolts rau corrosion thiab nruj. Saib xyuas kev ua haujlwm siab, tsis txhob tshaj qhov ntsuas PN.
Kev tu ncua sij hawm
Tighten flange bolts diagonally txhua xyoo (qhov system depressurized). Hloov EPDM / NBR gasket txhua 3-5 xyoos. Kho cov txheej uas puas lawm.
Ceeb toom
Tsis txhob zawm lossis disassemble flange nyob rau hauv siab. Gasket tsis tuaj yeem rov siv dua tom qab disassembly. Tsis txhob yuam kev sib dhos thaum lub sijhawm teeb tsa. Tiv thaiv kom tsis txhob sib haum hauv av rau faus installation.
Daim ntawv thov Scenario
Kev xa dej hauv nroog thiab cov kav dej hauv nroog: siv rau kev hloov pauv loj ntawm cov kav dej loj thiab cov kab; kuj rau txoj kab uas hla hloov ntawm cov kav dej phwj hauv nroog.
Cov dej ntws hauv av thiab cov kav dej nag hauv cov zej zog; loj-hloov pob qij txha rau hauv qab daus sump pit pipework.
Cov chaw kho cov dej phwj tuaj thiab cov chaw tso dej: kev hloov pauv kev sib txuas rau cov yeeb yaj kiab zoo nkauj, cov dej nkag thiab qhov hluav taws xob ntawm cov tso tsheb hlau luam biochemical.
Factory circulating dej system thiab cog cov kav dej phwj tuaj; haum rau me me-tso dej conveyance rau me-thiab- nruab nrab chemical sites.
Cov tsev lag luam thiab chaw nres tsheb hauv av: txoj kab uas hla hloov pauv hauv cov dej tiv thaiv hluav taws thiab cov kav dej.
Cov chaw kho dej thiab cov phiaj xwm rov qab-dej, ua haujlwm loj-hloov pob qij txha rau cov txheej txheem kav dej.
Kev daws teeb meem
| txhaum | Ua rau | Kev daws |
|---|---|---|
| Flange lub ntsej muag to | Loose bolts / aged gasket / impurities ntawm flange ntsej muag | Depressurize thiab ntws pipeline, zawm bolts tusyees nyob rau hauv kab pheeb ces kaum; hloov gasket yog tias siv tsis tau |
| Sab nrauv phab ntsa corrosion | Txheej puas, av corrosion | Sib tsoo thiab tshem tawm xeb, thov FBE / epoxy txheej; ntxiv cathodic tiv thaiv rau faus installation |
| Internal txheej peeling | Nruab nrab corrosion, dej rauj, cuam tshuam thaum lub sij hawm installation | Nres ua haujlwm thiab disassemble rau kev tshuaj xyuas; hloov ob lub flanged taper reducer yog tias muaj kev puas tsuaj loj heev |
| Flange tawg | Overpressure, lub hauv paus kev daws teeb meem, yuam kev sib dhos thaum lub sijhawm teeb tsa | Nres kev pabcuam tam sim ntawd, hloov qhov haum thiab kho cov yeeb nkab txhawb nqa |
