Izintambo zokushisisa zikagesi ezingaqhumi futhi zimelana nokugqwala ziyinketho yokuqala ezindaweni ezinomswakama

Imikhiqizo yokushisisa ugesi kanye ne-insulation isetshenziswa kakhulu emkhakheni wokufakwa kwamapayipi ezindaweni ezijwayelekile, izindawo ezivutha umlilo neziqhumayo, nezindawo ezithandwa ukugqwala. Ukufakwa kwamapayipi ezindaweni ezinomswakama nakho kulungele ukusetshenziswa kwezinyathelo zokufakelwa kwe-tape yokushisa kagesi. Isibonelo, ukushisisa nokushisisa kwamapayipi okuvikela umlilo ongaphandle, amapayipi amanzi kampompi ongaphandle, njll. Uma kuqhathaniswa nokufakwa kwamapayipi ezindaweni ezijwayelekile, ukusetshenziswa kokushisisa kukagesi ukuze kufakwe amapayipi ezindaweni ezinomswakama kudinga ukucatshangelwa kwezindaba ezinjengokuvimbela amanzi kanye nokufakwa kwamanzi. Kunconywa ukuthi imikhiqizo yokufakelwa kwe-tape yokushisa kagesi enezakhiwo eziphezulu zemishini kufanele ikhethwe njengenketho yokuqala yokushisa kagesi ezindaweni ezinomswakama.

Uma uthatha isibonelo somkhiqizo wokushisisa ugesi ozibekela wona umkhawulo njengesibonelo, khetha isivikelo esingaqhumi noma esingaqhumi kanye nokushisisa kukagesi okunqanda ukugqwala. Umgodla wangaphandle wokushisisa kukagesi ovikela ukuqhuma wenziwe ngezinto ze-pololefin, ezinokusebenza okuphezulu kokuphepha, ukufakwa okungangeni kwamanzi, namandla aphezulu emishini. Ngaphezu kwalokho, i-sheath yangaphandle yekhebula lokushisa kagesi elizincisha ukuqhuma kanye ne-anti-corrosion self-limiting senziwa nge-fluoroplastic, enokusebenza okuhle kwe-anti-corrosion kanye nomphumela omuhle wokusebenzisa. Ibuye ifanele ukusetshenziswa ezindaweni ezinomswakama wokufakwa kwamapayipi. Ukushisa okuzilawulayo kokuzivikela okuvikela ukuqhuma kungavikela ngempumelelo ibhande langaphakathi elingaphakathi ezweni elingaphandle futhi kuvimbele ukuguguleka komswakama nokuguguleka kwemvula.

Ngaphezu kwalokho, isikhunta kulula ukukhula kwezinye izindawo ezinomswakama, okuzogqwalisa umgodla wangaphandle wekhebuli yokushisisa kagesi. Ngalesi sikhathi, khetha intambo yokushisa kagesi ene-fluoroplastic sheath, ekwazi ukumelana nokugqwala futhi enempilo ende yesevisi, ukusebenza kahle, futhi ifanele izindawo ezinomswakama. Izinyathelo zokuqapha zokufaka ukushisisa kukagesi ezindaweni ezinomswakama:

1. Ukunikezwa kwamandla kokushisisa kukagesi kufanele kufakwe idivayisi yokuvikela ukuvuza njengento eyisisekelo, kanye nokuthi ingabe iyidivayisi evikela ukuqhuma kufanele kukhethwe. Ngoba endaweni enomswakama, uma izinyathelo zokuvikela amanzi zingenziwa kahle, ukuvuza kungenzeka kakhulu. Ngakho gwema ingozi. Kudingeka sithathe amathuluzi okuphepha ekusetshenzisweni kokuphakelwa kukagesi.

2. Sebenzisa ibhokisi lokuhlangana elinokusebenza kokuvikela okungangeni manzi ukuze kuxhunywe phakathi. Khipha itheyiphu yokuvikela engangeni manzi noma izindlela zezintambo ezingazinzile ukuze kubangele ukuchithwa; uma usebenzisa ibhokisi lokuhlangana, ibhokisi lokuhlangana akufanele libizwe phezulu ukuze kugwenywe ukungena kwemvula. Uma ufaka ibhokisi lokuhlangana, sebenzisa i-sealant (eyaziwa nangokuthi i-703 silicone) ukuyilungisa. Le 703 sealant inemiphumela engangeni manzi futhi elwa nokuguga.

3. Ezindaweni ezinomswakama ongaphandle, ukwahlukanisa kwangaphandle kufanele kukhuphule izinyathelo zokungangeni manzi ukuze kugwenywe ukushisisa isikhathi eside kwamabhande kagesi okushisisa ezimweni eziphansi zokushisa, okuzothinta impilo yesevisi yemikhiqizo yokushisisa ugesi.

4. Ngemva kokufakwa kwesistimu yokushisisa kagesi, ilebula eyisixwayiso kufanele ifakwe epayipini lapho kufakwa khona ibhande lokushisisa likagesi.
