Txhawm rau kom tau raws li cov neeg siv cov kev xav tau thiab cov kev daws teeb meem, ntau yam kev txuas / kev sib txuas yog tsim nyob rau hauv kev tsim cov yeeb nkab tsim Insulated / jacketed yeeb nkab.
Ua ntej sib tham txog kev sib txuas / kev sib txuas, muaj ob qho xwm txheej yuav tsum tau txawv,
1. Qhov kawg ntawm lub tshuab nqus tsev insulated piping system txuas nrog rau lwm cov khoom siv, xws li lub khw muag khoom thiab khoom siv,
A. WELD Coupling
B. Flange Coupling
C. V-Qhab Clamping
D. bayonet txuas ntxiv
E. Threaded Coupling
2. Raws li lub tshuab nqus tsev insulated piping system muaj ntev ntev, nws tsis tuaj yeem tsim thiab thauj ntau yam. Yog li ntawd, tseem muaj cov hlua khi ntawm cov kav dej khov kho insulated.
A. Welded Coupling (sau perlite mus rau hauv lub tes tsho insulated)
B. Welded Coupling (Lub Tshuab nqus tsev-tawm ntawm lub tes tsho insulated)
C. Nqus bayonet txuas nrog flanges
D. Nqus bomet bayonet txuas nrog v-band clamps
Cov ntsiab lus hauv qab no yog hais txog cov sib txuas hauv qhov xwm txheej thib ob.
Welded Txuas Hom
Cov hom txuas txuas ntawm sab nraud ntawm lub tshuab nqus tsev insulated kav yog welded kev sib txuas. Tom qab paub tseeb tias Weld taw tes nrog NDT, nruab lub tes tsho rwb thaiv tsev thiab sau lub tes tsho nrog kev thaiv kev kho mob. (Lub tsho ntawm no kuj tseem tuaj yeem nqus tau, lossis ob qho tib si sib xyaw ua ke. Cov tsos ntawm lub tes tsho puv nrog Perlite.)
Muaj ntau cov khoom series rau Welded Kev sib txuas hom tshuab nqus tsev insulated. Ib qho yog qhov haum rau MAWP hauv qab 16bar, ib qho yog txij li 40bar, ib tus yog 64bar, thiab tus kawg yog rau cov kev pab hydrogen thiab Helium Service (-270 ℃).
Nqus Plasting Txuas Hom nrog Flanges
Ntxig cov txiv neej nqus plua plav mus rau hauv cov poj niam nqus dej txuas ntxiv thiab muaj kev nyab xeeb nws nrog Flange.
Muaj peb yam khoom rau lub tshuab nqus tsev bayononet txuas hom (nrog flange) ntawm lub tshuab nqus tsev insulated. Ib qho yog tsim nyog rau lub mawp hauv qab no 8bar, ib qho yog rau lub mawp hauv qab 16bar, thiab tus kawg yog qis dua 25bar.
Nqus Plasting Txuas Hom nrog V-Qhab Clamps
Ntxig cov txiv neej nqus plua plav mus rau hauv cov poj niam sib txuas thiab muaj kev nyab xeeb nws nrog V-band clamp. Qhov no yog hom kev teeb tsa ceev, muaj feem xyuam rau VI piping nrog cov siab siab thiab lub taub me me.
Nyob rau tam sim no, hom kev sib txuas no tsuas yog siv thaum lub mawp yog tsawg dua 8bar thiab sab hauv tej ntxig tsis loj dua DN25 (1 ').
