Hydrostatic Kev Ntsuam Xyuas
Cov yeeb nkab yuav tsum tau txais kev kuaj hydrostatic yam tsis muaj kev lom los ntawm Weld Seam lossis Yeeb Nkab Lub Cev
Cov tub ntxhais kawm tsis tas yuav muaj kev sim hydrostatically, muab cov feem ntawm cov yeeb nkab siv hauv kev khij cov pob qij txha ua ntej ua ntej kev koom ua haujlwm.
Tracaulity:
Rau PSL 1 Yeeb Nkab, cov chaw tsim tshuaj paus yuav tsum tsim thiab ua raws cov txheej txheem sau tseg rau kev saib xyuas:
Cov kev kuaj kub kub kom txog thaum txhua qhov kev xeem chmical tau ua thiab ua raws nrog cov kev xav tau tshwj xeeb yog qhia
Cov kev xeem-chav kuaj xyuas kom txog thaum txhua qhov kev ntsuas uas cuam tshuam nrog thiab ua haujlwm nrog cov kev cai tshwj xeeb yog qhia
Rau psl 2 yeeb nkab, tsim cov chaw tsim tshuaj yuav tsim thiab ua raws cov txheej txheem sau tseg rau kev tswj hwm cov cua sov thiab cov xeem ntawv rau tus kheej rau cov yeeb nkab. Cov txheej txheem no yuav tsum muaj txoj kev tsim nyog rau tracing ib qho ntev ntawm cov yeeb nkab mus rau chav kuaj kom yog thiab cov tshuaj ntsuam xyuas kom raug.
