Yuav kom ua tau raws li cov kev xav tau thiab kev daws teeb meem ntawm cov neeg siv sib txawv, ntau hom kev sib txuas/kev sib txuas tau tsim tawm hauv kev tsim cov yeeb nkab uas muaj lub tshuab nqus tsev rwb thaiv tsev/hnav.
Ua ntej tham txog kev sib txuas / kev sib txuas, muaj ob qho xwm txheej yuav tsum tau sib txawv,
1. Qhov kawg ntawm lub tshuab nqus tsev rwb thaiv tsev txuas nrog lwm yam khoom siv, xws li lub tank cia khoom thiab cov khoom siv,
A. Kev Sib Txuas Weld
B. Kev Sib Txuas Flange
C. V-band Clamp Coupling
D. Kev Sib Txuas Bayonet
E. Kev Sib Txuas Xov
2. Vim tias lub tshuab nqus tsev rwb thaiv tsev kav dej ntev, nws tsis tuaj yeem tsim thiab thauj mus los tag nrho. Yog li ntawd, kuj tseem muaj cov kev sib txuas ntawm cov kav dej rwb thaiv tsev.
A. Kev Sib Txuas Welded (Sau Perlite rau hauv Lub Tes Tsho Insulated)
B. Kev Sib Txuas Welded (Lub Tshuab Nqus Tsev Twj Tso Kua Mis)
C. Lub Tshuab Nqus Tsev Bayonet Coupling nrog Flanges
D. Lub Tshuab Nqus Tsev Bayonet Coupling nrog V-band Clamps
Cov ntsiab lus hauv qab no yog hais txog cov couplings hauv qhov xwm txheej thib ob.
Hom Kev Sib Txuas Welded
Hom kev sib txuas ntawm cov kav dej nqus tsev yog kev sib txuas vuam. Tom qab paub meej qhov chaw vuam nrog NDT, ntsia lub tsho rwb thaiv tsev thiab sau lub tsho nrog pearlite rau kev kho rwb thaiv tsev. (Lub tsho ntawm no kuj tuaj yeem nqus tsev, lossis ob qho tib si nqus tsev thiab sau nrog perlite. Qhov tsos ntawm lub tsho yuav txawv me ntsis. Feem ntau pom zoo kom sau lub tsho nrog perlite.)
Muaj ntau yam khoom siv rau kev sib txuas ntawm cov yeeb nkab nqus tsev uas muaj cov khoom rwb thaiv tsev. Ib qho yog tsim rau MAWP hauv qab 16bar, ib qho yog txij li 16bar txog 40bar, ib qho yog txij li 40bar txog 64bar, thiab qhov kawg yog rau cov kua hydrogen thiab helium kev pabcuam (-270 ℃).
Hom Kev Sib Txuas Bayonet Nqus Tsev Nrog Flanges
Ntxig lub Yeeb Nkab Txuas Ntxiv Txiv Neej rau hauv lub Yeeb Nkab Txuas Ntxiv Poj Niam thiab khi nws nrog lub flange.
Muaj peb yam khoom series rau hom kev sib txuas bayonet nqus tsev (nrog flange) ntawm Cov Yeeb Nkab Nqus Tsev Insulated. Ib qho yog haum rau MAWP qis dua 8bar, ib qho yog rau MAWP qis dua 16bar, thiab qhov kawg yog qis dua 25bar.
Hom Kev Sib Txuas Nqus Tsev Bayonet Nrog V-band Clamps
Ntxig lub Tshuab Nqus Tsev Txiv Neej Txuas Ntxiv rau hauv lub Tshuab Nqus Tsev Poj Niam Txuas Ntxiv thiab khi nws nrog lub v-band clamp. Qhov no yog ib hom kev teeb tsa sai, siv tau rau VI Piping nrog lub siab qis thiab lub raj me me.
Tam sim no, hom kev sib txuas no tsuas yog siv tau thaum MAWP tsawg dua 8bar thiab lub raj sab hauv txoj kab uas hla tsis loj dua DN25 (1 ').
