Lub voj voog flangingnon-metallic expansion sib koom ua kethiab daim tawv nqaij tsis yog xim hlau yog ib hom ntawm cov tawv nqaij uas tsis yog xim hlau. Piv nrog rau qhov zoo tib yam hemming expansion sib koom ua ke ntawm daim tawv nqaij, thaum lub sij hawm tsim khoom, lub rhiav yuav tsum tau ua ib puag ncig los yog square fab kom yooj yim installation raws li cov duab kos. Cov txheej txheem ntau lawm yog qhov nyuaj dua. Cov tawv nqaij tsis yog xim hlau yog ib hom tshiab ntawm cov khoom siv hluav taws xob thermal rwb thaiv tsev uas tsim los ntawm cov iav fiber ntau thiab silica gel coated iav fiber ntau ntaub thiab lwm yam khoom siv hluav taws kub thiab kub resistant. Piv nrog cov ntaub ntawv hlau, kev ua tau zoo ntawm cov ntaub ntawv tsis yog hlau xws li kub tsis kam, acid thiab alkali tsis kam thiab tshuaj lom neeg ruaj khov tau dhau deb tshaj ntawm cov ntaub ntawv hlau. Qhov tsis zoo ntawm cov tawv nqaij uas tsis yog xim hlau hloov tau yog tias lawv tsis tuaj yeem siv rau hauv qhov chaw muaj kev kub ntxhov. Feem ntau hais lus, nyob rau hauv ib puag ncig tshaj 0.5mpa, nws yog ib qho tsim nyog yuav tsum xav txog kev siv cov hlau txuas ntxiv lossis cov roj hmab uas tsis yog hlau txuas ntxiv.
Yuav ua li cas npaum li cas cov non-metallic expansion pob qij txha?
1. Lub flange bolts yuav tsum tau nruj me ntsis thiab uniformly, thiab lub nruj ntawm lub bolts yuav tsum tau raws li qhov yuav tsum tau. Hauv cov xwm txheej hnyav, lub caij nplooj ntoos hlav tsis muaj zog tuaj yeem ntxiv ntxiv rau lub tshuab ntxhua khaub ncaws kom tiv thaiv cov txiv ntoo los ntawm loosening.
2. Cov roj hmab asbestos zoo sib xws yuav tsum tau siv ua ntej raws li kev ua haujlwm kub ntawm qhov sib koom ua ke thiab qhov sib txuam tiaj tiaj vuam flange.
3. Thaum lub sij hawm sim khiav, qhov txwv cov ntsia hlau ntawm kev sib koom ua ke yuav tsum tau kho kom zoo los pab txhawb qhov txuas ntxiv lossis compression ntawm cov khoom.
4. Thaum cov yeeb nkab welded txuas, txwv cov ntsia hlau yuav tsum tau xoob kom zoo los tiv thaiv cov phaj txwv ntawm kev sib koom ua ke los ntawm kev khoov lossis cov khoom deformed.
5. Thaum lub sijhawm ua haujlwm vuam, nws yog siv los ua lub hau npog rau saum npoo ntawm cov roj hmab (ntaub) los tiv thaiv vuam slag los ntawm kev puas tsuaj rau cov khoom.
