ASTM B163 Condenser thiab Heat-Exchanger Tubes kam rau ua
Thaum nws los txog rau xaiv txoj cai tubing rau condensers thiab tshav kub exchangers, ASTM B163 feem ntau yog mus rau tus qauv. Nws teev cov specifications rau seamless npib tsib xee thiab npib tsib xee alloy condenser thiab tshav kub exchanger raj, kom ntseeg tau kev ua tau zoo thiab ntev nyob rau hauv xav tau kev lag luam daim ntaub ntawv.
Cov qib siab rauASME SB163 tubesNws txawv nyob ntawm seb lawv loj thiab phab ntsa thickness. Piv txwv li, cov raj uas muaj txoj kab uas hla tsawg dua {{0}}.5 ntiv tes muaj qhov ua siab ntev ntawm +/-0.005 ntiv tes rau sab nraud. Rau txoj kab uas hla ntawm 0.5 thiab 1.5 ntiv tes, qhov kam rau siab nce mus rau +/-0.010 ntiv tes. Ib yam li ntawd, qhov kam rau ntawm phab ntsa thickness ranges ntawm +/-10% rau +/-15%.
Cov kev kam rau siab no yuav zoo li me me, tab sis lawv ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm lub condenser lossis cov khoom siv hluav taws xob. Txawm tias me ntsis sib txawv tuaj yeem cuam tshuam cov dej ntws, cuam tshuam rau cov cua sov hloov pauv, lossis cuam tshuam lub raj lub peev xwm sealing. Tias yog vim li cas nws yog ib qho tseem ceeb rau cov raj uas ua tau raws li lossis tshaj ASTM B163 cov kev cai kam rau ua.
