ASTM B161 qhia cov kev cai rau seamless npib tsib xee thiab npib tsib xee alloy condenser thiab cua kub exchanger raj. Cov raj no feem ntau siv rau ntau yam kev lag luam uas muaj kev tiv thaiv corrosion thiab kev ua haujlwm kub yog qhov tseem ceeb. Tus txheej txheem npog seamless raj ua los ntawm npib tsib xee thiab npib tsib xee alloys, kom ntseeg tau tias lawv ua tau raws li qhov tsim nyog tshuaj muaj pes tsawg leeg, txhua yam khoom, qhov ntev, thiab lwm yam kev qhia tshwj xeeb rau lawv qhov kev npaj siv.
