Umbhobho ogqunyiweyo yinkqubo yokubhobhoza kunye ne-thermal insulation. Umsebenzi wayo ophambili kukunciphisa ukulahleka kobushushu ngexesha lokuthutha kweendaba (njengamanzi ashushu, i-steam, kunye neoli eshushu) ngaphakathi kombhobho ngelixa ukhusela umbhobho kwiimpembelelo zendalo. Isetyenziswa ngokubanzi ekwakheni ukufudumeza, ukufudumeza kwesithili, iikhemikhali zepetroli, ubunjineli bakamasipala, kunye nezinye iindawo.
1. Ulwakhiwo olungundoqo
Umbhobho ogqunyiweyo udla ngokuba lulwakhiwo oluhlanganisiweyo olunamacandelo amathathu:
• Umbhobho wentsimbi oSebenzayo: Umbindi ongaphakathi, onoxanduva lokuthutha amajelo eendaba. Iimathiriyeli ngokuqhelekileyo ziquka intsimbi engenamthungo, intsimbi, okanye imibhobho yeplastiki, kwaye kufuneka ikwazi ukumelana noxinzelelo kunye nokungadleki.
• I-Insulation Layer: Umaleko obalulekileyo ophakathi, onoxanduva lokugquma kwe-thermal. Izinto eziqhelekileyo ziquka i-polyurethane foam, uboya belitye, uboya beglasi, kunye ne-polyethylene. Igwebu lePolyurethane okwangoku lolona khetho luphambili ngenxa yokuhanjiswa kwe-thermal ephantsi kunye nokusebenza okugqwesileyo kokugquma.
• I-Outer Sheath: Umaleko ongaphandle okhuselayo ukhusela umaleko wokugquma kumanzi, ukuguga, kunye nomonakalo owenziwe ngumatshini. Izinto eziqhelekileyo ziquka i-polyethylene ephezulu (HDPE), i-fiberglass, okanye i-anti-corrosion coating.
II. Iintlobo eziphambili kunye neempawu
Ngokusekwe kwimathiriyeli yokugquma kunye nemeko yesicelo, iintlobo eziqhelekileyo kunye neempawu zimi ngolu hlobo lulandelayo:
• I-Polyurethane Insulated Pipe: I-Thermal conductivity ≤ 0.024 W / (m·K), ukusebenza kakuhle kwe-insulation ephezulu, ukumelana nokushisa okuphantsi, kunye nokuguga. Ifanele amanzi ashushu kunye nemibhobho yomphunga kunye namaqondo obushushu aphakathi kwe -50°C kunye ne-120°C, lolona khetho lukhethwayo lokufudumeza okuphakathi kunye neenkqubo zokufudumeza umgangatho.
• I-Rockwool Insulated Pipe: Ukumelana nobushushu obuphezulu (ukuya kwi-600 ° C) kunye nomgangatho ophezulu womlilo (i-Class A engenakutsha), kodwa ngokugqithiswa kwamanzi amaninzi, kufuna ukubunjwa komswakama. Isetyenziswa ikakhulu kwimibhobho yobushushu obuphezulu kwishishini (njengemibhobho yebhoyila yomphunga).
• Umbhobho ogqunyiweyo woboya beglasi: UKhaphukhaphu, nonesigqubuthelo sesandi esigqwesileyo, kunye noluhlu oluxhathisayo lobushushu obuyi-120°C ukuya kuma-400°C, ulungele imibhobho yobushushu obuphantsi (njengemibhobho enesikhenkcezisi somoya) kunye nokugquma imibhobho kwizakhiwo zokuhlala.
III. Iingenelo ezingundoqo
1. Ukugcinwa kwamandla kunye nokuNcitshiswa kokuSetyenziswa: Ukunciphisa ukulahleka kobushushu phakathi, ukunciphisa ukusetyenziswa kwamandla ekufudumeni, ukuveliswa kwemveliso, kunye nezinye iimeko. Ukusetyenziswa kwexesha elide kunokunciphisa kakhulu iindleko zokusebenza.
2. Ukukhuselwa koMbhobho: Isingxobo sangaphandle sikhusela kumanzi, ukudleka komhlaba, kunye neempembelelo zoomatshini, ukwandisa ubomi benkonzo yombhobho kunye nokunciphisa ukugcinwa rhoqo.
3. Ukusebenza koMbhobho oZinzileyo: Ukugcina ubushushu obuphakathi obuzinzileyo ukukhusela ukuguquguquka kwamaqondo obushushu ekuchaphazeleni ukusebenza (umzekelo, ukugcina ubushushu obungaphakathi kwimibhobho yokufudumeza nokuqinisekisa uzinzo lwenkqubo yemibhobho yeshishini).
4. Ufakelo oluLungileyo: Eminye imibhobho efakwe i-insulated ifakwe ngaphambili, ifuna kuphela uqhagamshelo lwendawo kunye nofakelo, ukunciphisa ixesha lokwakha kunye nokunciphisa ubunzima.
IV. Usetyenziso olusebenzayo
• Umasipala: Uthungelwano lokufudumeza kwindawo esezidolophini kunye nemibhobho yamanzi etephu (ukuthintela umkhenkce ebusika).
• Ulwakhiwo: Imibhobho yokufudumeza emgangathweni kwizakhiwo zokuhlala kunye nezorhwebo, kunye nemibhobho yokufudumeza nephakathi yokupholisa yomoya ophakathi.
• Imizi-mveliso: Imibhobho yeoli eshushu kwimizi-mveliso yepetroleum neyekhemikhali, imibhobho yomphunga kwimizi-mveliso yombane, kunye nemibhobho ephakathi ecryogenic kulungiselelo lwesixokelelwano esibandayo.
