China thermal insulation steel pipe factory
Umbhobho wokufakelwa kwe-thermal usetyenziswa kakhulu kuthungelwano lwemibhobho yolwelo kunye negesi, umbhobho wekhemikhali wokufakelwa kwe-thermal ubunjineli, i-petroleum, ishishini lemichiza, uthungelwano lokufudumeza eliphakathi, umbhobho wokungenisa umoya womoya ophakathi, ubunjineli bakamasipala, njl njl.
Ubume bokufakelwa kwe-thermal yentsimbi enebhatyi yentsimbi edityanisiweyo yombhobho wentsimbi yokufudumeza inokwahlulwa ngokweendidi ezimbini ngokweendlela ezahlukeneyo zokutyibilika:
1.Uhlobo lwangaphakathi lokutyibilika: Isakhiwo sokufakelwa kwe-thermal senziwe ngombhobho wensimbi osebenzayo, i-aluminium silicate, umaleko wokunciphisa ukutsalwa, i-microporous calcium silicate, i-thermal insulation layer, intsimbi engenasici, intsimbi yentsimbi, i-aluminium foil reflection layer, i-polyurethane thermal insulation layer, umbhobho wentsimbi yangaphandle kunye umaleko wokuchasa umhlwa wangaphandle. Umbhobho wensimbi wokugcinwa kobushushu obungaphakathi bohlobo lwangaphakathi luqulunqwe ngumbhobho wokuhambisa umbhobho, i-silicate edibeneyo okanye i-silicate ye-calcium microporous, i-polyurethane eqinile yeplastiki ye-foam, ipayipi yensimbi yangaphandle kunye ne-shell ye-FRP ye-anticorrosive layer . Itekhnoloji yonyango lokufakelwa kwe-thermal yokufakelwa kwemibhobho eyahlukeneyo ikhulile kwaye umgangatho uthembekile.
2. Uhlobo lokutyibilika lwangaphandle: ulwakhiwo lokufakelwa kwe-thermal lwenziwe ngombhobho wentsimbi osebenzayo, umaleko weglasi woboya obushushu, umaleko we-aluminium foil reflection, intsimbi engenasici, ibhanti lentsimbi eqinileyo, inkxaso yesikhokelo sokutyibilika, umaleko wokugquma umoya, umbhobho wentsimbi okhuselayo wangaphandle kunye nolwaleko oluchasene nomhlwa. .
1. Umbhobho wentsimbi yangaphakathi
2. Zinc etyebileyo primer
3. Isibiyeli sesikhokelo sokutyibilika
4. Uboya beglasi obuxhathisa ubushushu obuphezulu
5. Isibonisi sefoyile yeAluminiyam
6. Umaleko wokugquma umoya
7. Umbhobho wentsimbi yebhatyi
8. Umbhobho wentsimbi yangaphandle yokugquma ukugquma
Umbhobho wentsimbi odityanisiweyo wentsimbi ngomnye wemibhobho engaphantsi komhlaba engcwatywe ngokuthe ngqo. Iyakwazi ukungcwatywa phantsi komhlaba ngaphandle kwesakhiwo sekhonkrithi, oko kukuthi, ukwandiswa kwe-thermal yombhobho wensimbi osebenzayo kuqhutyelwa kumbhobho wangaphandle, okunciphisa iindleko zezinto eziphathekayo, ukunciphisa umhla wokwakha, ukuqinisekisa ukhuseleko lombhobho wokufudumeza, kwaye unako. ikhuseleke ngakumbi kwaye isetyenziswe ngokubanzi kwiindawo ezahlukeneyo zobushushu, Ilungele ngakumbi iiprojekthi zemibhobho yomphunga wobushushu obuphezulu. Ubushushu benkonzo bunokufikelela kwi-150 ℃ - 450 ℃. Iziphelo zombhobho zitywinwa ngokubanzi ngefilimu ye-polyethylene okanye iteyiphu epholileyo enemigangatho emithathu ye-PE ukukhusela ukufuma okanye amanzi ukuba angangeni phambi kofakelo okanye ngexesha lokwakha. I-multi-layer staggered dinding of thermal insulation materials inciphisa ngokufanelekileyo ilahleko yobushushu. Kwangaxeshanye, amanyathelo olawulo athathwa kumphezulu wemikhono yangaphandle ukuthintela ukuveliswa kwebhulorho ebandayo, ukuze kuqinisekiswe ulawulo lobushushu bomkhono ongaphandle wokwaleka umhlwa. Umaleko we-aluminiyam yefoyile ebonisa i-multilayer isongelwe ngemathiriyeli yokugquma i-thermal, ethi icuthe ngokufanelekileyo ilahleko yobushushu kwaye yenze umbhobho womphunga ube noqoqosho ngakumbi kwaye ube nengqiqo. Inkqubo yokuhambisa amanzi ivalwe ngokupheleleyo, kunye nesakhiwo esiguquguqukayo, isakhiwo esifanelekileyo, ukhuseleko kunye nokuthembeka. Umbhobho wokukhupha umswakama kwi-casing yensimbi awukwazi nje ukukhupha igesi enomswakama ngexesha, kodwa usebenze njengombhobho wesignali ye-alarm yokusebenza kwansuku zonke. Imbuyekezo ye-thermal yombhobho ithatha i-compensator ye-bellows ephezulu, efakwe kwi-casing kwaye yenziwe kwifom engcwatywe ngokuthe ngqo. Akukho mfuneko yokuseta uqwalaselo kakuhle. Umsebenzi wokwakha ulungele kwaye ixesha lokwakha lifutshane. Ilungele ukuhambisa umphunga okanye enye imidiya engaphantsi kwe-2.5MPa kunye ne-350 ℃. Imveliso isebenzisa umbhobho wensimbi njengoluhlu lwangaphandle olukhuselayo, olunenzuzo yamandla aphezulu, akulula ukulimaza, ukwakhiwa okulula kunye nokugcinwa kunye nobomi benkonzo ende.
Ukuze kuncitshiswe ukutshatyalaliswa kobushushu bombhobho emhlabeni, umaleko odityanisiweyo wokugquma we-thermal wongezwa ngaphandle kombhobho ophakathi kunye nobubanzi obuncinci bokuhambisa ubushushu be-oyile ekrwada okanye umbhobho wokufudumeza. Izinto ezisetyenziswa ngokuqhelekileyo zokugquma i-thermal yi-polyurethane foam eqinile, kwaye ubushushu buphakathi kwe-18 kunye ne-120 degrees. Esi sixhobo sithambileyo kwisicatshulwa. Ukuze kuphuculwe amandla alo, umaleko we-high-density polyethylene layer isetyenziswa ngaphandle kwe-thermal insulation layer ukwenza isakhiwo sezinto ezidibeneyo zokukhusela amanzi angaphantsi komhlaba ukuba angene kwi-thermal insulation layer. Iseti epheleleyo yezixhobo zokupholisa amagwebu ze-polyurethane ezinoxinzelelo oluphezulu zisetyenziselwa ukudubula ukususwa komhlwa kumphezulu ongaphandle wombhobho wentsimbi kunye nonyango lwe-corona kumphezulu ongaphakathi wombhobho ongaphandle wokukhusela, ukuze kuphuculwe ukusebenza kwebhondi yombhobho wokugquma oshushu. I-insulating layer material yi-polyurethane foam eqinile kunye noxinano lwe-60kg / m3 ukuya kwi-80kg / m3. Umsantsa phakathi kombhobho wensimbi kunye ne-casing uzaliswe ngokupheleleyo kwaye unamandla athile okudibanisa, ukwenzela ukuba yonke into eqinileyo inokubunjwa phakathi kweengxenye ezintathu zombhobho wensimbi, umbhobho wangaphandle we-sleeve kunye ne-insulation layer. I-Polyurethane foam ineempawu ezintle zomatshini kunye neempawu zokugquma i-thermal. Phantsi kweemeko eziqhelekileyo, inokumelana namaqondo obushushu angama-120 ngokukaCelsius. Iyakwazi ukumelana nobushushu be-180 degrees ngokuguqula okanye ukudibanisa nezinye izinto zokugquma.
Umbhobho wentsimbi owenziweyo we-polyurethane ofakwe ngaphambili wahlulwe waba ngamacandelo amathathu ukusuka ngaphakathi ukuya ngaphandle:
Umgangatho Wokuqala: ukusebenza umgangatho umbhobho wentsimbi
Ngokuhambelana noyilo kunye neemfuno zabathengi, umbhobho wentsimbi ongenamthungo, umbhobho wentsimbi ojikelezayo kunye nombhobho wentsimbi womthungo othe ngqo ukhethwa ngokubanzi. Emva kokuba umphezulu wombhobho wensimbi uphathwe ngokuqhushumba okuphambili, ibakala lokususa umhlwa lombhobho wensimbi linokufikelela kwi-SA2 kwi-GB / t8923-1988 esemgangathweni, kwaye uburhabaxa bomhlaba bunokufikelela kwi-r = 12.5 microns kwi-gb6060.5-88 standard.
Umaleko wesibini: umaleko wokugquma i-polyurethane
Iplastiki enogwebu eqinileyo ye-polyurethane igalelwa kumgodi owenziwe phakathi kombhobho wentsimbi kunye neshethi yangaphandle ngumatshini woxinzelelo oluphezulu, owaziwa ngokuba yi "tube in tube foaming".
Umaleko wesithathu: ingxinano ephezulu polyethylene umaleko okhuselayo
Yenziwe ngaphambili kwimibhobho yeplastiki yepolyethylene emnyama okanye emthubi enobunzima obuthile bodonga. I-polyethylene ayinavumba, ayinayo ityhefu kwaye ivakala ngathi yi-wax. Inokumelana nobushushu obuphantsi. Ubuncinci bobushushu benkonzo bunokufikelela - 70 ~ - 100 ℃. Inozinzo olulungileyo lweekhemikhali, luyakwazi ukuxhathisa ukukhukuliseka kwee-asidi ezininzi kunye neziseko (ezingenakuchasana ne-acids eneempawu ze-oxidizing), ayinakunyibilika kwi-solvents ngokubanzi kwiqondo lokushisa, kwaye iyancipha amanzi. Nangona kunjalo, ngenxa yokuba imolekyuli ehambelanayo, inokunyibilika kancinci kwezinye izinyibilikisi zendalo ngaphandle kokudumba, Ukufakwa kombane okugqwesileyo. Umsebenzi wayo kukukhusela i-polyurethane insulation layer kwizinto ezinzima zomatshini, kwaye enye i-anti-corrosion kunye ne-waterproof. Uxinaniso oluphezulu lwe-polyethylene i-polyurethane ye-foam yokufakelwa umbhobho wensimbi iya kuhambelana nemigangatho ye-SY / t114-2000 kunye ne-SY / t115-2001.
