Kev ceev faj thaum txhim kho grooved yeeb nkab fittings

1. Thaum txiav txim qhov grooved, xaiv lub nplhaib sealing tsim nyog. Cov xov xwm sib txawv hauv cov raj xa dej yuav tsum tau ntim cov nplhaib ntawm cov khoom sib txawv. Tam sim no, muaj yim hom kev sib khi ntawm cov khoom sib txawv ntawm lub khw kom haum rau cov xov xwm sib txawv.

2. Cov yeeb nkab zawj (tseem hu ua rolling groove) yog cov txheej txheem tseem ceeb ntawm cov yeeb nkab txuas, thiab tseem yog qhov txuas tseem ceeb uas txiav txim siab qhov kev sib txuas zoo ntawm qhov grooved. Qhov dav thiab qhov tob ntawm qhov trench yuav tsum ua tau raws li qhov yuav tsum tau ua. Thaum grooving, qhov kawg ntawm lub nozzle yuav tsum tiaj tus thiab tsis muaj burrs, thiab qhov chaw nres nkoj yuav tsum tau perpendicular mus rau lub axis ntawm cov yeeb nkab, yog li ntawd lub dov zawj yuav tsum tau perpendicular mus rau lub central axis ntawm cov yeeb nkab, thiab qhov ntev ntawm cov yeeb nkab. zawj rau cov yeeb nkab kawg yuav tsum sib npaug. Yog hais tias lub ovality ntawm cov yeeb nkab thiab cov phab ntsa thickness ntawm cov welded galvanized yeeb nkab yog unevenly, nws yuav tsum tau kho kom ntau li ntau tau thaum dov lub zawj, txwv tsis pub lub zawj yuav muaj ib tug sib sib zog nqus qhov tob, thiab lawv nruj nreem tsis tau guaranteed.

3. Rau kev sib txuas ntawm cov kav dej seamless steel, cov khoom uas tau raug galvanized los ntawm cov chaw tsim khoom niaj hnub yuav tsum tau xaiv. Yog tias txoj kev yuav khoom seamless steel kav thiab tom qab ntawd tawm mus rau galvanizing yog siv, galvanizing zoo tsis tuaj yeem lav vim oxidation thiab corrosion tshwm sim los ntawm kev cia ntev ntawm cov kav hlau. Lub adhesion ntawm galvanized txheej yog tsis zoo, thiab galvanized txheej yog yooj yim rau tawg los yog txawm poob tawm thaum dov lub zawj, yog li cuam tshuam rau lub sealing thiab kev pab cuam lub neej. Txhawm rau kom ua tiav kev sib khi zoo tom qab lub raj xa dej tau teeb tsa, ntxiv rau kev yuav khoom grooved nrog kev ua tau zoo thiab ua kom ntseeg tau tias lub nplhaib sealing tsis puas, txheej ntawm nruab nrab lubricant yuav tsum tau siv rau lub flange thiab sab nraud ntawm lub nplhaib sealing thaum lub sij hawm installation. los xyuas kom meej lub nplhaib sealing. Daim di ncauj thiab cov yeeb nkab foob haum nruj dua.

4. Kev siv cov pob qij txha nruj thiab cov pob qij txha hloov tau yooj yim hauv qhov grooved yuav tsum tsim nyog. Rigid pob qij txha yog tsim rau cov yeeb nkab kawg uas yuav tsum tau nruj kev sib txuas nyob rau hauv cov kav dej uas tsis tshua muaj siab, xws li sprinkler risers, ntev-ntev ncaj kav, li qub, khoom siv, thiab lwm yam zoo rigidity. Cov pob qij txha yooj yooj yim haum rau kev sib txuas ntawm cov kav dej nruab nrab thiab tsis tshua muaj siab. Tom qab kev teeb tsa, cov kav dej tau tso cai kom muaj qhov tsim nyog shrinkage thiab deflection, thiab me ntsis kev hloov pauv ntawm cov kav dej yog them nyiaj. Nws yog qhov tsim nyog rau kev teeb tsa cov kav dej hauv qhov chaw tsis sib xws; nws tseem tuaj yeem nqus suab nrov, kev co, thiab av qeeg kev nyuaj siab. Nws feem ntau yog siv rau hauv cov kav dej thiab qhov hluav taws xob ntawm cov twj tso kua dej hauv cov tshuab tiv thaiv hluav taws.

5. Yog hais tias qhov kev ncua deb ntawm cov hluav taws kub sib ntaus sib tua kab rov tav yeeb nkab yog ntev, thaum lub hanger yog siv, thiaj li yuav suppress cov yeeb nkab channeling, nws yog pom zoo kom siv ib tug saj zawg zog sib koom ua ke nyob rau hauv nruab nrab ib feem kom paub meej tias lub axial channeling tsis loj. , thiaj li tsis cuam tshuam rau kev khoov ntawm cov kab rov tav ceg txuas nrog nws.

6. Thaum txhim kho cov kav dej tua hluav taws hauv qhov chaw uas muaj qhov sib txawv ntawm qhov kub thiab txias, thaum cov kav dej siv cov hlua khi ruaj khov thiab tiv thaiv kev co, cov pob qij txha hloov tau thiab cov pob qij txha tuaj yeem siv ua ke, kom cov axial quab yuam tsim los ntawm kev hloov siab los yog kub sib txawv. yuav tsis cuam tshuam rau ceg kab rov tav. khoov.
