Kev tawg-pov thawj thiab corrosion-resistant hluav taws xob cua sov cables yog thawj qhov kev xaiv hauv qhov chaw ntub dej

Cov khoom siv hluav taws xob cua sov thiab rwb thaiv tsev yog dav siv hauv thaj chaw ntawm cov yeeb nkab rwb thaiv tsev hauv cov chaw zoo tib yam, thaj chaw tawg thiab tawg, thiab cov cheeb tsam uas muaj kev xeb. Pipeline rwb thaiv tsev nyob rau hauv ib puag ncig humid kuj tsim nyog rau kev siv hluav taws xob cua sov daim kab xev ntsuas rwb thaiv tsev. Piv txwv li, kev rwb thaiv tsev thiab cua sov ntawm cov kav dej tiv thaiv hluav taws sab nraum zoov, cov kav dej tawm sab nraum zoov, thiab lwm yam. Piv nrog cov raj xa hluav taws xob hauv cov chaw zoo tib yam, kev siv hluav taws xob cua sov rau cov kav dej rwb thaiv tsev hauv qhov chaw ntub dej yuav tsum tau xav txog cov teeb meem xws li cov dej tsis zoo thiab rwb thaiv tsev. Nws raug pom zoo tias cov khoom siv hluav taws xob hluav taws xob hluav taws xob rwb thaiv tsev nrog cov khoom siv hluav taws xob siab yuav tsum raug xaiv los ua thawj qhov kev xaiv rau hluav taws xob cua sov hauv cov chaw ntub dej.

Siv cov khoom siv hluav taws xob ua kom sov rau nws tus kheej ua piv txwv, xaiv cov khoom tiv thaiv tawg lossis tawg-pov thawj thiab tiv thaiv corrosion hluav taws xob cua sov. Lub plhaub sab nraud ntawm qhov hluav taws xob tiv thaiv hluav taws xob tawg yog ua los ntawm cov khoom siv polyolefin, uas muaj kev nyab xeeb kev ua tau zoo, rwb thaiv tsev tsis muaj dej, thiab muaj zog txhua yam. Tsis tas li ntawd, sab nrauv ntawm qhov tawg-pov thawj thiab tiv thaiv corrosion nws tus kheej-txheej kub hluav taws xob cua sov cable yog ua los ntawm fluoroplastic, uas muaj kev tiv thaiv corrosion zoo thiab siv tau zoo. Nws kuj yog tsim rau siv nyob rau hauv cov av noo rau cov yeeb nkab rwb thaiv tsev. Kev tawg-pov thawj tiv thaiv tus kheej tswj qhov kub thiab txias hluav taws xob cua sov tuaj yeem tiv thaiv lub hauv paus tseem ceeb los ntawm lub ntiaj teb sab nraud thiab tiv thaiv kev ya raws thiab nag yaig.

Tsis tas li ntawd, pwm yog ib qho yooj yim kom loj hlob nyob rau hauv tej qhov chaw ntub dej, uas yuav corrode lub txheej sheath ntawm hluav taws xob cua sov cable. Nyob rau lub sijhawm no, xaiv lub tshuab hluav taws xob cua sov nrog lub fluoroplastic sheath, uas yog corrosion-resistant thiab muaj lub neej ntev kev pab cuam, kev ua tau zoo, thiab tsim nyog rau cov chaw ntub dej. Kev ceev faj rau kev txhim kho hluav taws xob cua sov hauv thaj chaw ntub dej:

1. Cov khoom siv hluav taws xob hluav taws xob hluav taws xob yuav tsum tau nruab nrog cov cuab yeej tiv thaiv hluav taws xob raws li qhov yooj yim, thiab seb nws puas yog cov khoom tawg-pov thawj yuav tsum raug xaiv. Vim hais tias nyob rau hauv ib qho chaw ntub dej, yog tias ib qho kev ntsuas dej tsis tau ua tiav zoo, qhov xau yuav tshwm sim heev. Yog li zam kev phom sij. Peb yuav tsum tau siv cov cuab yeej siv kev nyab xeeb hauv kev siv lub zog hluav taws xob.

2. Siv lub thawv sib txuas nrog kev tiv thaiv dej tsis zoo rau kev sib txuas ntawm. Tshem tawm cov ntaub nplaum uas tsis yog-waterproof insulating daim kab xev los yog cov txheej txheem tsis ruaj khov los ua kom tawg; Thaum siv lub thawv sib txuas, lub thawv sib txuas yuav tsum tsis txhob raug hu mus rau pem hauv ntej kom tsis txhob muaj nag lossis daus. Thaum txhim kho lub thawv sib txuas, siv cov sealant (tseem hu ua 703 silicone) los kho nws. Qhov no 703 sealant muaj dej tsis zoo thiab tiv thaiv kev laus.

3. Nyob rau hauv qhov chaw ntub dej sab nraum zoov, cov rwb thaiv tsev sab nraud yuav tsum ua kom cov dej tsis muaj dej kom tsis txhob muaj cua sov mus ntev ntawm cov hlua hluav taws xob cua sov hauv qhov kub thiab txias, uas yuav cuam tshuam rau lub neej kev pab cuam ntawm cov khoom siv hluav taws xob.

4. Tom qab lub tshuab hluav taws xob cua sov tau teeb tsa, yuav tsum tau muab daim ntawv ceeb toom rau cov yeeb nkab uas lub tshuab hluav taws xob siv hluav taws xob tau teeb tsa.
