carbon steel kav rau cua sov exchangers thiab condensers.
ASME SA-179/SA-179M yog ib hom American seamless steel yeeb nkab txheem rau seamless txias-draw low-carbon steel kav rau tshav kub exchangers thiab condensers. Cov yeeb nkab steel no muaj qhov tsawg kawg nkaus phab ntsa tuab thiab tsim nyog rau tubular cua sov exchangers, condensers, thiab cov khoom siv hluav taws xob zoo sib xws. Cov txheej txheem no siv rau cov kav hlau uas muaj qhov ntev ntawm 1/8 ntiv tes thiab 3 ntiv tes (3.2 txog 76.2mm).
SA179 sib raug rau Tuam Tshoj tus No. 10 seamless steel yeeb nkab. SA179 thiab A179 yog tiag tiag No. 10 seamless steel kav. Nyob rau hauv Suav teb, No. 10 seamless steel kav feem ntau yog siv rau tshav kub exchangers ntawm cov khoom siv hluav taws xob sib pauv uas tsis raug hluav taws xob ncaj qha, thiab muaj cov xwm txheej zoo sib xws li SA179.
ASME SA179 seamless kav yuav raug tsim los ntawm cov txheej txheem zoo ib yam thiab yuav txias-dhau. Carbon, manganese, phosphorus thiab sulfur ntsiab yog ntxiv rau cov hlau. Cov hlau tseem yuav raug kuaj xyuas qhov nyuaj, ntsuas qhov ncaj, ntsuas qhov ntsuas, ntsuas tav thiab ntsuas hydrostatic kom paub meej lub cev ntawm ASME SA179 superheater kav.
