Dab tsi yog Mos Copper Pipe (Annealed Copper Tube)?
Mos tooj liab yeeb nkab, kuj hu uaannealed tooj liab tube, yog cov yeeb nkab tooj liab uas tau ua kom sov thiab maj mam txias kom nce ductility. Qhov notxheej txheem annealingtshem tawm cov kev ntxhov siab sab hauv los ntawm cov tooj liab, ua rau cov yeeb nkabyoog raws thiab yooj yim khoov yam tsis muaj cracking.
Tsis zoo li cov yeeb nkab tawv tooj liab (dab ntxwg nyoog), cov yeeb nkab tooj liab yog nkag rau hauvcoils, tso cai raunruam piping khiav nrog ob peb pob qij txha. Qhov no yuav txo tau cov ntsiab lus xau thiab txo cov nqi zog ua haujlwm.
Cov kauj ruam tseem ceeb ntawm kev tsim cov yeeb nkab tooj liab:
Extrusion ntawm tooj liab billet rau hauv ib lub raj
Annealing (kub rau 400-650 degree, ces tswj txias)
Ntxuav thiab ziab
Coiling
Kev ntsuas siab thiab kev soj ntsuam zoo
