ASTM B111 UNS C68700 Seamless Aluminium Brass Tube
ASTM B111 yog tus qauv specification rau seamless tooj liab thiab tooj liab alloy condenser raj thiab ferrule Tshuag. UNS C68700 yog ib qho tshwj xeeb tooj liab alloy hu ua txhuas tooj dag. ASTM B111 UNS C68700 seamless tubing yog tsim los siv cov txheej txheem hu ua extrusion, nyob rau hauv uas cov khoom siv ntawm tooj liab alloy yog rhuab thiab yuam los ntawm kev tuag los ua ib lub raj tsis muaj seams lossis welds. Cov raj no muaj kev tiv thaiv corrosion zoo heev thiab thermal conductivity, ua rau lawv zoo tagnrho rau kev siv dej hiav txwv, marine heat exchangers, thiab fais fab nroj tsuag. Cov raj no muaj nyob rau hauv ntau qhov ntau thiab tsawg thiab phab ntsa tuab thiab tuaj yeem ua tau yooj yim zoo li, khoov, thiab fabricated kom tau raws li cov kev cai tshwj xeeb.
ASTM B111 UNS C68700 seamless tubings muaj nyob rau hauv tus txheej txheem cov kab uas hla thiab phab ntsa thicknesses. Tubing feem ntau yog 0.25 "mus rau 2" nyob rau hauv txoj kab uas hla, nrog ib phab ntsa thickness xws li 0.035" mus rau 0.065". ASTM B111 qhia txog ntau yam kev sim thiab tshuaj xyuas cov txheej txheem rau seamless tubing kom lav tias nws ua tiav cov txheej txheem cuam tshuam. Kev sim hydrostatic, kev ntsuas tam sim no, thiab kev soj ntsuam qhov ntev yog cov piv txwv ntawm kev sim ntau. Cov kev ntsuam xyuas no tau ua tiav los lav tias lub raj tsis muaj qhov tsis xws luag thiab muaj qhov tsim nyog txhua yam thiab tshuaj zoo.
