Uyini umehluko phakathi kwethreyi lekhebula elinembobo kanye nethreyi yekhebula yohlobo lomkhombe

1,Izinhlelo zokusebenza ezahlukene

Ithreyi lekhebula lomkhombe:ifanele ukubeka izintambo zekhompyutha, izintambo zokuxhumana, i-thermocoupleikhebulas kanye nolunye uhlelo lokulawula olubucayi kakhuluizintambo, njll.

Pithreyi lekhebula elicijile: isetshenziswa kakhulu ku-petroleum, amakhemikhali, embonini ekhanyayo, ithelevishini, ezokuxhumana, njll.

2,Izinzuzo ezahlukene

Cumkhombe okwaziyo: kunomthelela ongcono ekuphazamiseni kokuvikela ikhebula nokuvikela izintambo ezindaweni ezigqwalile.

Ithreyi lekhebula elinomoya: inezinzuzo zesisindo esincane, umthwalo omkhulu, ukuma okuhle, isakhiwo esilula, ukufakwa kalula, njll. Ifanele kokubili ukufakwa kwezintambo zamandla, kodwa futhi nokubeka izintambo zokulawula

3, Izinhlobo ezahlukene ongakhetha kuzo

Uhlobo lwethreyi yekhebula:.

(1) isidingo sokuvikela inethiwekhi yekhebula yokuphazamiseka kukagesi noma sibe nesivikelo kwangaphandle (njengokuthi: ukuphumula koketshezi olubolayo, uthuli oluvuthayo nezinye izindawo) izidingo zomthelela, kufanele kukhethweumkhombeikhebula elivikelwe lokulwa nokugqwala eliyinhlanganiselaamathileyi(enekhava).

(2) indawo eqinile egqwalayo kufanele isetshenziswe (F) isigaba se-epoxy resin anti-corrosionithreyi lekhebula elibuyisela amalangabi.Ingalo yebakaki,isiteshi se-strut, ubakaki kufanele futhi basebenzise into efanayo ukuthuthukisa impilo yesevisi yeithreyi lekhebulakanye nezinsiza, ikhebulaiziteshiku lula ukunqwabelana uthuli nezinye isidingo ukumboza imvelo noma izindawo zangaphandle kufanele wengeze ipuleti cover.

(3) Ngaphezu kwalokhu okungenhla, ngokwendawo nendawo kanye nezidingo zobuchwepheshe ongakhetha kuzoenezimbobouhlobo,umkhombeuhlobo,iladiuhlobo, intambo yengilazi evimbela ukubola kwelangabiamathileyinoma uhlobo lwensimbi olujwayelekileithreyi lekhebula.In the lula buthelela uthuli nezinye isidingo ukumboza imvelo noma izindawo ongaphandle kufanele wanezela cover.

(4) Emzileni womphakathi noma engxenyeni yomgwaqo owela ngaphandle, iphansi lesitebhisi elingaphansi kufanele lifakwe kuphedi noma kusetshenziswe iphalethi esigabeni.Lapho uwela isiteshi somphakathi nge-span enkulu, umthamo wokulayisha webhuloho ungandiswa noma uhlaka lomugqa lungakhethwa ngokuvumelana nezidingo zomsebenzisi.

Ithreyi yekhebula yohlobo olunezimbobo.

(1)ikhebulaukubamba, iziqu neziphanyeko zazo ezizisekelayo ezisetshenziswa endaweni ebolayo, kufanele zenziwe kusetshenziswa izinto eziqinile ezimelana nokugqwala, noma zithathelwe ukwelashwa okuqeda ukugqwala, ukwelashwa kwe-anti-corrosion kufanele kuhlangabezane nezimfunekoubunjiniyelaimvelo kanye nokuqina.

(2)ikhebulaamathileyi ezidingweni zomlilo zesigaba, zingangezwa ohlakeni lwesitebhisi sekhebula, ithreyi elinezinto ezikwazi ukumelana nomlilo noma ezivimbela ilangabi zepuleti, inethiwekhi nezinye izinto zokwakha isakhiwo esivaliwe noma esivaleke kancane, futhi sithathe izinyathelo ezinjengokuthi ukudweba enamathela umlilo phezu kwebhuloho kanye yayoisiphanyeko sokusekela, ukumelana kwayo nomlilo kukonke kufanele kuhlangabezane nezimfuneko zenkambiso noma izindinganiso zikazwelonke ezifanele.

(3) ezidingweni zomlilo wephrojekthi wezindawo eziphakeme, akufanele zisetshenzisweikhebula le-aluminiumithileyis.

(4)iladi lekhebulaithileyi, ububanzi nobude bethreyi kufanele kukhethwe ukuze kuhlangatshezwane nezidingo zenani lokugcwalisa,iladi lekhebulaisilinganiso sokugcwalisa uhlaka kanye nethreyi ngokujwayelekile, izintambo zikagesi zingaba ngu-40% kuya ku-50%, izintambo zokulawula zingaba ngu-50% kuya ku-70%, futhi kufanelekile ukubekela eceleni u-10% kuya ku-25% womkhawulo wokuthuthukiswa kwephrojekthi.
