ASTM A234 carbon steel hla teeyog plaub- chaw nres nkoj yeeb nkab haum ua los ntawmcarbon hlau, tsim los txuas plaub ntu yeeb nkab thiab tsimbranching nyob rau hauv piping systems. Feem ntau,ob qhov chaw nres nkoj tau ua raws li txoj kab ncaj nraim (kab loj), thaum lublwm ob qhov chaw nres nkoj yog perpendicular rau kab loj (kab kab).
Txheem Specification
ASTM A234 / A234M specification npog wrought carbon steel thiab alloy steel fittings ntawm seamless thiab welded tsim. Cov fittings no yog siv rau hauv cov kav dej siab thiab hauv kev tsim cov hlab ntsha siab rau kev pabcuam ntawm qhov nruab nrab thiab siab kub. Cov khoom siv rau fittings yuav tsum muaj cov hlau tua, forgings, tuav, daim hlau, seamless los yog fusion-welded tubular cov khoom nrog muab tub lim ntxiv. Forging los yog shaping kev khiav hauj lwm yuav ua tau los ntawm hammering, nias, tho, extruding, chim siab, dov, dabtsi yog khoov, fusion vuam, machining, los yog ua ke ntawm ob los yog ntau tshaj ntawm cov kev khiav hauj lwm. Kev tsim cov txheej txheem yuav tsum tau siv kom nws yuav tsis tsim kev puas tsuaj tsis zoo hauv cov fittings. Fittings, tom qab tsim ntawm qhov kub siab, yuav tsum tau txias rau qhov kub hauv qab qhov tseem ceeb nyob rau hauv cov xwm txheej tsim nyog los tiv thaiv kev raug mob los ntawm kev ua kom txias heev, tab sis tsis muaj qhov xwm txheej ceev tshaj qhov cua txias hauv huab cua. Cov fittings yuav tsum raug kuaj nruj, kuaj hardness, thiab ntsuas hydrostatic.
