Paipi yotsekera wosanjikizaimatchedwanso thermal pipeline insulation layer, yomwe imatanthawuza mawonekedwe osanjikiza ozungulira payipi yomwe imatha kugwira ntchito yoteteza kutentha ndi kutchinjiriza kutentha.Chigawo chotchinjiriza mapaipi nthawi zambiri chimakhala ndi zigawo zitatu: zosanjikiza zotchingira, zosanjikiza zoteteza, komanso zosanjikiza madzi.Imawonetsetsa kufalikira kwamadzi ndi gasi mupaipi, imachepetsa kutayika kwa mphamvu, imatalikitsa moyo wapaipi, ndikupulumutsa phindu pazachuma.Izi ndi ubwino wakusungunula mapaipi.
Popanga mphira ndi kusungunula pulasitiki, ogwira ntchito ku Tekmax Company amayezera kaye kukula kwa mapaipi otsekedwa, akasinja, etc. Dziwani mphira wofunikira ndi mapulasitiki ndi zinthu zina, konzani, kenako tsatirani njira zochitira chitsulo. kumanga kutchinjiriza mapepala ndi kukulunga chitsulo pepala Pamwamba pa mipope ndi akasinja amene ayenera insulated, ntchito mawaya zitsulo kulumikiza izo kuteteza zitsulo khungu kugwa.Chigawo chomangacho chiyeneranso kukulunga mosamala mbali zokwezeka monga mapaipi ndi zida kuti zitsimikizire kuti kutentha kumayembekezeredwa.
1 The kutchinjiriza mapaipi ndi zipangizo ayenera kutsukidwa ngalande ndi chubu zitsime, ndipo kutchinjiriza angathe kuchitidwa kokha ngati palibe kuwononga kuphwanya wosanjikiza mu ndondomeko yotsatira.
2 Nthawi zambiri, kutchinjiriza kwa mapaipi kuyenera kukhala koyenera pakuyezetsa kuthamanga kwa madzi, ndipo anti-corrosion imatha kumangidwa, ndipo njirayi siyingasinthidwe.
3 Zipangizo zotchingira mphira ndi pulasitiki siziyenera kugwa mvula kapena kusungidwa pamalo achinyezi polowa pamalopo.
4 Zinyalala zomwe zatsala pambuyo poteteza kutentha ziyenera kutsukidwa ndi gulu lomwe limayang'anira ntchito yomanga.
5 Kwa kutchinjiriza kwa mapaipi owonekera, ngati ntchito zachitukuko zapopera, payenera kukhala njira zopewera kuipitsidwa kwa wosanjikiza wamafuta.
6 Ngati pali mikhalidwe yapadera yomwe ikufunika kuchotsa wosanjikiza wotsekereza pochiza mapaipi kapena mitundu ina ya ntchito kuwononga wosanjikiza wotsekereza pakumanga, iyenera kukonzedwa munthawi yake molingana ndi zofunikira zoyambirira.
Lero, mkonzi akufotokozerani njira zingapo zopangira chitoliro cha mafakitale.
1. Kusungunula thovu la polyurethane
Mu Shaanxi Pipeline Thermal Insulation Project, mwachindunji kukwiriridwa kutchinjiriza matenthedwe ndi payipi odana dzimbiri, amatchedwa chitoliro-mu-chitoliro, amatanthauza chitoliro gulu kuti yokutidwa ndi odana ndi dzimbiri wosanjikiza wosanjikiza matenthedwe kutchinjiriza wosanjikiza ndi psinjika wosanjikiza pa khoma lakunja la chitoliro chachitsulo.Makamaka oyenera kumadera okhala ndi milingo yamadzi apansi panthaka.Poyerekeza ndi mapaipi achikhalidwe oyika ngalande, ili ndi zabwino zingapo monga ntchito yabwino yotchinjiriza, anti-corrosion, ntchito yabwino yotchinjiriza, moyo wautali wautumiki, zomangamanga ndi kukhazikitsa kosavuta, kutsika pang'ono, komanso mtengo wotsika waukadaulo.Zakhala zikugwiritsidwa ntchito kwambiri pakutentha kwapakati, mayendedwe amafuta, makampani opanga mankhwala, firiji ndi ntchito zoperekera madzi m'magawo a alpine.
2. Phenolic thovu kusungunula
Phenolic thovu insulation ndi mtundu wa pulasitiki thovu wopezedwa ndi thovu phenolic utomoni.Pali mitundu iwiri ya ma resin omwe amagwiritsidwa ntchito popanga thovu la phenolic: utomoni wa thermoplastic ndi thermosetting resin.Chifukwa chakuchita bwino kwa utomoni wa thermosetting, thovu la phenolic limatha kupangidwa mosalekeza, ndipo ntchito yake ndi yabwinoko, chifukwa chake zida za thovu la phenolic nthawi zambiri zimagwiritsa ntchito utomoni wa thermosetting.
3. Zapamwamba mphira ndi pulasitiki kutchinjiriza
The mphira wapamwamba ndi pulasitiki zabwino matenthedwe kutchinjiriza kwenikweni, ndi makulidwe kutchinjiriza ntchito chitoliro chomwecho mu Shaanxi payipi ndi woonda, ndipo kuchuluka ndi kochepa;nthawi yomweyo, ndi integrally anapanga matenthedwe kutchinjiriza zakuthupi, ndondomeko ndi yosavuta, ndi kupita patsogolo mofulumira;kuwonjezera apo, mphira wapamwamba kwambiri ndi pulasitiki ndi wobiriwira, wokonda zachilengedwe, komanso waukhondo.Zida zopangira zoziziritsa kukhosi zimakhala ndi zinyalala zochepa pakumanga ndipo sizivulaza thanzi.Kutchinjiriza kwapamwamba kwa mphira ndi pulasitiki kumagwiritsidwa ntchito kwambiri popaka mapaipi a refrigerant ndi mapaipi a condensate mu makina oziziritsira mpweya.
4. Polystyrene thovu kusungunula
Kutchinjiriza thovu la polystyrene kuli ndi mawonekedwe otsekeka, kuyamwa kwamadzi otsika, kukana kutentha pang'ono, komanso kukana bwino kusungunuka.Choncho, amagwiritsidwa ntchito kwambiri pazida za firiji ndi zipangizo zosungirako zozizira, monga mafiriji, maulendo a mpweya wozizira, kusungirako kuzizira, etc. Komanso, chifukwa thovu la polystyrene ndilopanda poizoni, losawonongeka, laling'ono m'madzi, kuwala m'thupi. , kuteteza kutentha, kupanga nkhungu, ndi asidi ndi alkali kukana dzimbiri, angagwiritsidwe ntchito posungira kutentha kwa mapaipi pazifukwa zosiyanasiyana.
