Qauv

Lub cev tee yog integrally nrum tsis muaj vuam. Nws yog lined nrog cement mortar los tiv thaiv - corrosion thiab coated nrog epoxy nyob rau sab nrauv, ua raws li cov qauv kev thauj dej haus.

Lub ntsej muag sealing ntawm peb kawg flanges yog tiaj tus nrog lub qhov ntsia hlau tsis tu ncua, sib xws nrog cov kav hlau hlau, li qub thiab flanged ncaj kav ntawm tib qhov tshwj xeeb.

Nws nta ruaj khov siab muaj peev xwm, tsim nyog rau ib txwm thiab nruab nrab siab cov kav dej xws li cov dej hauv nroog, cov dej rov qab thiab cov dej ua haujlwm.

Flange kev twb kev txuas

Rigid flange kev twb kev txuas tso cai yooj yim disassembly thiab sib dhos. Tsis tas yuav txiav cov yeeb nkab rau kev kho tom qab lossis hloov yeeb nkab.

Sealed nrog roj hmab flange gaskets kom ua tiav kev ruaj ntseg sealing thiab zoo tiv thaiv kom tsis txhob xau.

Cov pob zeb sib cais tuaj yeem raug ntsia tau los tuav qhov hnyav ntawm cov yeeb nkab fittings, tshem tawm cov kabmob ntawm cov raj xa dej thiab txo qhov kev pheej hmoo ntawm kev sib koom ua ke.

Qhov zoo

Ib qho yooj yim disassembly thiab tu, zoo tagnrho rau cov chaw ua haujlwm nquag

Txais cov qauv flanged kev sib txuas, qhov haum tuaj yeem sib cais tsuas yog los ntawm kev tshem cov bolts yam tsis muaj cov yeeb nkab txiav thaum lub sij hawm tu, hloov kav dej lossis hloov valve. Nws yog qhov tshwj xeeb tshaj yog yooj yim rau kev tswj xyuas cov kav dej ntau zaus xws li chav twj tso kua mis thiab cov khoom siv hauv av hauv av, txiav kev tsim kho thiab kho lub sijhawm xwm txheej ceev.

Kev ua tau zoo sealing zoo, Leak - Dawb nyob rau hauv qis thiab siab siab

Muab nrog ib -daim seamless EPDM roj hmab flange gaskets. Lub flange sealing ntsej muag yog precision machined yam tsis muaj radial khawb. Tighten bolts diagonally nyob rau hauv ob peb kis thaum lub sij hawm installation kom ua tau zoo ib yam thiab nruj sealing, tiv thaiv dej seepage nyob rau hauv siab. Nws ua haujlwm tsis tu ncua rau qis- siab hauv cov kav dej hauv nroog nrog rau qhov nruab nrab thiab siab - cov kav dej muaj zog.

Kev ruaj ntseg thiab ruaj ntseg Load Bearing, txo qhov kev pheej hmoo ntawm kev sib koom ua ke thiab cov dej xau

Lub tee yog integrally cam khwb cia li ib daim nrog siab rigidity thiab mechanical zog. Kev ywj pheej qhob kev txhawb nqa piers tuaj yeem muab nchuav rau ntawm qhov chaw los tuav tus kheej - qhov hnyav ntawm qhov haum, yog li cov khoom thauj yuav tsis raug xa mus rau ob lub yeeb nkab kawg. Qhov no zoo tiv thaiv kev sib koom ua ke thiab cov dej xau los ntawm cov kav dej nruj, haum rau cov kav dej faus rau hauv txoj kev thiab thaj chaw uas muaj kev sib haum xeeb hauv av.

Lub neej ua haujlwm ntev nrog Superior Anti-Corrosion Performance

Qhov haum siv ob -txheej txheej tiv thaiv- kev kho corrosion: cement mortar hauv ob sab phlu thiab epoxy hmoov txheej rau sab nrauv, ua raws li cov qauv huv rau kev xa dej haus. Ua los ntawm siab -tuaj yeem hlau, nws tiv taus cov kua qaub thiab alkali corrosion los ntawm cov av, xa cov kev pab cuam lub neej ntawm ntau tshaj 50 xyoo nyob rau hauv ib txwm faus dej hauv nroog.

Flange Connection txheej txheem

Flange Ntxuav

Sib tsoo lub ntsej muag sealing ntawm ob lub flanges kom huv si tshem tawm xeb, residual qub gasket fragments thiab sediment. Xyuas kom lub sealing nto tsis muaj khawb thiab burrs.

Teem thiab tso Gasket

Precisely dlhos ob lub yeeb nkab flanges, tom qab ntawd tso ib qho roj hmab tag nrho lub hauv nruab nrab ntawm lawv. Lub gasket yuav tsum tsis txhob npog bolts qhov los yog protrude rau hauv cov yeeb nkab bore.

Ntxig Bolts thiab ua ntej-ntxoov

Tag nrho cov bolts yuav tsum tau muab tso rau hauv ib qho sib npaug ntawm sab nraud ntawm flanges sab hauv, nrog cov txiv ntseej ntawm tib sab. Ua ntej-tighten nyob rau hauv ib tug ntoo khaub lig kab pheeb ces kaum symmetrical ib theem xwb coj flanges mus rau hauv kev sib cuag nrog lub gasket.

Multi-stage Diagonal Uniform Tightening

Tighten bolts maj mam nyob rau hauv 3 rounds tom qab kab kab pheeb ces kaum nyob rau hauv tus txheej txheem. Zam ib qho -sab eccentric load uas tuaj yeem tsoo lub gasket thiab ua rau cov dej ntws tawm.

Kev Xeem Siab thiab Txais

Ua ib feem ntawm kev ntsuas hydrostatic ntawm cov kav dej. Nce siab rau 1.5 npaug ntawm kev ua haujlwm siab thiab tuav rau 30 feeb. Lub installation hla kev soj ntsuam yog tias tsis muaj seepage tshwm sim ntawm flanges thiab siab nyob ruaj khov. Nyob rau hauv cov ntaub ntawv ntawm to, tso siab, hloov lub gasket nrog ib tug tshiab thiab reinstall.
