ASTM A178 yog ib qho kev qhia tshwj xeeb rau hluav taws xob tiv thaiv welded (ERW) carbon steel yeeb nkab siv rau hauv boilers, superheaters, thiab tshav kub exchangers.
GNEE cov khoom sivASTM A178 boiler rajnyob rau hauv diameters xws li 1/2 nti mus rau 5 nti thiab phab ntsa thicknesses xws li ntawm 0 085 nti mus rau 0.500 nti. Lub zog tensile yam tsawg kawg nkaus yog 485 MPa thiab qhov tsawg kawg nkaus yield zog yog 275 MPa. Cov kav dej kuj raug tswj xyuas cov txheej txheem nruj nrog rau kev tshuaj xyuas, ntsuas thiab ntsuas hydrostatic kom ntseeg tau tias lawv ua tau raws li qhov yuav tsum tau ua.
ASTM A178 seamless tubing yog siv nyob rau hauv ntau daim ntawv thov xws li boilers, roj kab, tshav kub exchangers, superheaters, condensers thiab pub dej kav. Ua los ntawm cov pa roj carbon steel, cov kav dej no tuaj yeem tiv taus qhov kub txog li 750 degrees Fahrenheit yam tsis muaj kev tawg lossis tsis muaj zog. Vim lawv cov khoom tiv thaiv corrosion, lawv tsim nyog siv rau hauv thaj chaw raug cov ntsiab lus thiab yuav kav ntev dua lwm cov ntaub ntawv.
