Ukusetshenziswa kwepayipi lokufakwa kwe-thermal okuqondile ngokuqondile

I-Polyurethane ebhekiswe ngokuqondile ipayipi lokufakwa kwe-thermal ilungele ubunjiniyela bokufakwa kwe-thermal kwemidiya ehlukahlukene ebangeni le- -50 I-degree .℃.℃.℃. I-degree . I-degree . I-degree . I-degree ., i-Cold Pipeline Pipeline, amandla angcwatshwe ngentengo, Ipayipi le-Cable, ipayipi lokufakwa kwesitefu kanye nezinye izimboni zokufakwa kwe-thermal kanye nobunjiniyela bokuvikela obandayo .
Izinzuzo ze-polyurethane zingqepha ngokuqondile ishubhu lokufakwa kwe-thermal
1. Yehlisa izindleko zephrojekthi . Ngokuya ekubalweni kweminyango efanelekile, ipayipi elishisayo eliphindwe kabili, ngaphansi kwezimo zephrojekthi, ukusetshenziswa kwe-frp njengesendlalelo esivikelayo .
2. ukulahleka okushisa okuphansi kanye nokulondolozwa kwamandla . Ukusebenza kwalo okushisayo yilezi:
I-MHoC iphansi kakhulu kunamanye ama-Piperations wePhalamende asetshenziswa kakhulu esikhathini esedlule, futhi umphumela wokufakelwa yizikhathi ezi-4 ~ 9 eziphakeme {22. Isizathu sokuvalwa kwama-polyurethane Foam siseduze I-92% . Ukuvuselelwa okuphansi okushisayo kanye nokutholwa kwamanzi okuphansi, okuhambisana nongqimba wokufakelwa okuningana nokusebenza kwamanzi okuvikelayo, Ukulahleka kokushisa okuyisisekelo kwe-Pipeline " 10%.
3. ukumelana nokukhulisa ukubhuka, kanye nempilo yesevisi ende . ngoba i-polyurethane hard foam invation inyuswe eduze kwesikhumba sepayipi lensimbi namanzi, kungadlala umphumela omuhle wokulwa nokugqwala ngasikhathi sinye, namanzi ukumuncwa kuncane kakhulu Ngaphezu kweminyaka engama-50, okungu-3 ~ 4 amahlandla aphezulu kune-tren yendabuko ebekezelayo nokubeka ngaphezulu kwe- .
4. indawo engaphansi komhlaba, ukwakhiwa okusheshayo, futhi kuyathandeka ekuvikelweni kwemvelo Ukucutshungulwa kwamapayipi we-insulation kanye ne-in-site trench parallel, okuhlangene kwesiza, kunganciphisa isikhathi sokwakha ngaphezulu kwama-50% .
