ASTM A556 Gr B2 Steel Feedwater rhaub Tubes
ASTM A556, ASME SA 556 yog cov txheej txheem dav dav rau seamless txias drawn carbon steel feedwater rhaub tubing. Nws yog siv los ua cov phab ntsa dej-txias ntawm lub hwj chim chaw nres tsheb boilers, uas tuaj yeem tshem tawm cov yeeb yaj kiab ntawm cov yeeb yaj kiab sab hauv ntawm phab ntsa ntawm cov yeeb nkab steel thiab txhim kho cov thermal efficiency ntawm lub cub tawg.
Qhov kev qhia tshwj xeeb no siv rau qhov txias-daws seamless carbon steel yeeb nkab ntawm qhov tsawg kawg nkaus phab ntsa tuab siv rau hauv tubular feedwater rhaub, suav nrog khoov rau hauv U-shaped kav raws li tau teev tseg. Qhov ntau thiab tsawg ntawm cov yeeb nkab npog yuav tsum yog 5/8 txog 1 2/4 nyob rau hauv. [15.9 mus rau 31.8 mm] sab nraud txoj kab uas hla, suav nrog, nrog rau qhov tsawg kawg nkaus phab ntsa thickness sib npaug los yog ntau dua 0.045 nyob rau hauv. [1.1 mm].
