Kev kub siab yeeb nkab installation

Cov kev xav tau rau kev teeb tsa lub raj xa dej siab zoo ib yam li cov kev teeb tsa nruab nrab thiab qis qis, tab sis cov kev xav tau siab dua thiab cov kev cai nruj dua. Yog li ntawd, ntxiv rau kom ua tau raws li qhov yuav tsum tau ua rau nruab nrab- thiab qis-siab pipeline installation, yuav tsum tau ua raws li cov cai hauv qab no. Txij li cov phab ntsa ntawm cov kav dej muaj zog yog thicker, xuab zeb filling feem ntau tsis tas yuav tsum tau thaum khoov.
Cov khoom siv hluav taws xob siab, cov yeeb nkab fittings, fasteners thiab li qub siv rau kev teeb tsa yuav tsum raug tshuaj xyuas thiab tsim nyog, thiab nrog rau cov ntaub ntawv pov thawj kev sib raug zoo. Tom qab thauj mus rau qhov chaw, lawv yuav tsum tau muab khaws cia kom zoo, ua kom pom tseeb thiab muab tso kom zoo. Ua ntej kev teeb tsa, qhov chaw sab hauv thiab sab nrauv yuav tsum tau muab ntxuav kom huv, thiab cov kab sab hauv yuav tsum tau kuaj xyuas cov khoom txawv teb chaws thiab seb lawv puas tsis muaj kev cuam tshuam. Xyuas seb qhov roughness ntawm lub qhov ncauj sealing nto thiab lub sealing gasket ua tau raws li qhov yuav tsum tau ua. Yuav tsum tsis muaj khawb (tshwj xeeb tshaj yog radial scratches) los yog me ntsis ntawm lub sealing nto uas cuam tshuam rau kev sealing kev ua tau zoo. Tsuas yog cov kav dej uas yuav tsum tau degreased, cov yeeb nkab lub qhov ncauj sealing nto thiab sealing gasket yuav tsum tau coated nrog roj cav, butter lossis vaseline dawb rau kev tiv thaiv.
Cov threaded ib feem ntawm cov yeeb nkab siab kawg uas tau dhau qhov kev tshuaj xyuas, tshwj tsis yog cov kav dej uas yuav tsum tau degreased, yuav tsum tau coated nrog molybdenum disulfide roj los yog graphite cav roj sib tov rau kev tiv thaiv.
Thaum txhim kho lub raj xa dej, nws yuav tsum tau kho nrog cov yeeb nkab raug cai. Ntawm cov yeeb nkab khib hauv kev sib cuag nrog cov kav dej siab thiab cov yeeb nkab fittings, lub tes tsho tiv thaiv yuav tsum tau muab ntsia raws li cov qauv tsim. Thaum txhim kho lub siab-siab flange, lub chamfer ntawm cov yeeb nkab kawg xov yuav tsum raug nthuav tawm. Thaum txhim kho lub gasket, tsis txhob siv hlau los dai nws. Roj rau lub qhov ncauj qhov ncauj thiab gasket ua ntej, thiab cov hlau mos siab siab gasket yuav tsum raug muab tso rau hauv lub rooj sib khi.
Lub flange bolts yuav tsum tau nruj nreem symmetrically thiab tusyees, thiab yuav tsum tsis txhob ntau dhau. Tom qab cov bolts tau nruj, ob lub flanges yuav tsum nyob twj ywm tib yam thiab concentric. Cov xov nthuav tawm sab nraum lub txiv ntoo yuav tsum yog 2 ~ 3 buckles, yam tsawg kawg tsis pub tsawg dua 2 buckles, thiab qhov ntev ntawm txhua lub bolts yuav tsum yog tib yam.
Thaum lub sij hawm lub installation txheej txheem, muaj zog rub, muaj zog thawb, muaj zog twisting los yog hloov lub thickness ntawm lub gasket yuav tsum tsis txhob siv los them rau kev tsim khoom los yog installation yuam kev. Yog tias qhov kev teeb tsa lub raj xa dej tsis tuaj yeem ua tiav thiab ua tiav tas li, qhib lub qhov ncauj qhov ncauj yuav tsum raug kaw rau lub sijhawm. Qhov chaw ntawm qhov ntsuas ntsuas qhov ntsuas ntawm lub raj xa dej yuav tsum tau nruab rau tib lub sijhawm raws li cov kav dej.
Thaum cov yeeb nkab steel hlau raug kho rau qhov curvature hauv zos, nws cov cua sov yuav tsum tau tswj xyuas hauv qab qhov kub tseem ceeb ntawm cov hlau.
Tom qab lub raj xa dej tau teeb tsa, cov ntawv cim steel ntawm lub raj xa dej yuav tsum tau kuaj xyuas tag nrho. Yog tias nws pom tias cov ntawv hlau tsis muaj nyob rau qhov twg, nws yuav tsum tau ntxiv rau lub sijhawm raws li lub hauv paus tseem ceeb.
