Txhawm rau ua kom tau raws li cov neeg siv khoom xav tau thiab cov kev daws teeb meem sib txawv, ntau hom kev sib txuas / kev sib txuas yog tsim los ntawm kev tsim lub tshuab nqus tsev insulated / jacketed yeeb nkab.
Ua ntej sib tham txog kev sib txuas / kev sib txuas, muaj ob qhov xwm txheej yuav tsum tau paub qhov txawv,
1. Qhov kawg ntawm lub tshuab nqus tsev insulated piping system txuas nrog rau lwm yam khoom siv, xws li lub tank cia thiab khoom siv,
A. Weld Coupling
B. Flange Coupling
C. V-band Clamp Coupling
D. Bayonet Coupling
E. Threaded Coupling
2. Raws li lub tshuab nqus tsev insulated piping system muaj qhov ntev, nws tsis tuaj yeem tsim thiab thauj tag nrho. Yog li ntawd, kuj tseem muaj cov couplings ntawm lub tshuab nqus tsev insulated kav.
A. Welded Coupling (Filling Perlite rau hauv lub tes tsho Insulated)
B. Welded Coupling (Nqus twj tso kua mis-tawm lub tes tsho Insulated)
C. Vacuum Bayonet Coupling nrog Flanges
D. Vacuum Bayonet Coupling nrog V-band Clamps
Cov ntsiab lus hauv qab no yog hais txog cov couplings hauv qhov xwm txheej thib ob.
Welded Kev Txuas Hom
Hom kev sib txuas ntawm qhov chaw ntawm Lub Tshuab Nqus Tsev Insulated Pipes yog welded kev twb kev txuas. Tom qab lees paub qhov vuam taw tes nrog NDT, nruab lub tsho rwb thaiv tsev thiab sau lub tes tsho nrog pearlite rau kev kho rwb thaiv tsev. (Lub tes tsho ntawm no kuj tuaj yeem nqus tau, lossis ob qho tib si nqus thiab ntim nrog perlite. Cov tsos ntawm lub tes tsho yuav txawv me ntsis. Feem ntau pom zoo lub tes tsho uas muaj perlite.)
Muaj ntau ntau yam khoom siv rau welded kev twb kev txuas hom Vacuum Insulated Pipe. Ib qho yog tsim rau MAWP qis dua 16bar, ib qho yog los ntawm 16bar mus rau 40bar, ib qho yog los ntawm 40bar mus rau 64bar, thiab qhov kawg yog rau cov kua hydrogen thiab helium kev pab (-270 ℃).
Vacuum Bayonet Kev Txuas Hom Nrog Flanges
Ntxig lub Nqus Txiv Neej Extension Pipe rau hauv Lub Nqus Poj Niam Extension Pipe thiab ruaj ntseg nrog flange.
Muaj peb yam khoom series rau lub tshuab nqus tsev bayonet kev twb kev txuas hom (nrog flange) ntawm lub tshuab nqus tsev Insulated yeeb nkab. Ib qho yog tsim rau MAWP hauv qab 8bar, ib qho yog rau MAWP hauv qab 16bar, thiab qhov kawg yog qis dua 25bar.
Vacuum Bayonet Kev Txuas Hom Nrog V-band Clamps
Ntxig lub Nqus Txiv Neej Extension Pipe rau hauv Lub Nqus Poj Niam Extension Pipe thiab ruaj ntseg nrog v-band clamp. Qhov no yog ib hom kev txhim kho sai, muaj feem xyuam rau VI Piping nrog qis siab thiab me me txoj kab uas hla.
Tam sim no, hom kev sib txuas no tsuas yog siv tau thaum MAWP tsawg dua 8bar thiab cov kab yeeb nkab sab hauv tsis loj dua DN25 (1').
