Ci ntsa iab annealed tooj liab tubing yog ze li ntawm cov ntshiab tooj liab tubing tsim raws li cov cai ntawm ASTM B 68 (Standard Specification for Bright Annealed Seamless Copper Tubing). Nws tuaj yeem tsim los ntawm ib qho ntawm cov alloys hauv qab no: C10200, C10300, C10800, C12000 lossis C12200, tshwj tsis yog tias tau teev tseg hauv thawj daim ntawv cog lus lossis kev yuav khoom. ASTM B68 yeeb nkab yog tsim rau siv nyob rau hauv tub yees, roj, roj av, los yog cov kav dej uas lub puab nto ntawm cov yeeb nkab yog qhov tseem ceeb tsis muaj cov nplais los yog av thiab tshwj xeeb yog ASTM B68.
Cov txheej txheem annealing ntawm cov yeeb nkab no ua tau raws li O50 (lub teeb annealing) lossis O60 (mos annealing), txawm tias ncaj los yog coiled.
Seamless tooj liab yeeb nkab tsis muaj cov ntsiab lus vuam thiab muaj lub zog siab. Vim tias seamless tooj liab kav tsis muaj cov ntsiab lus vuam thaum lub sijhawm tsim khoom, lawv muaj lub zog siab thiab kev ntseeg siab. Cov kav dej zoo tib yam muaj cov ntsiab lus vuam ntau dua thiab muaj zog me ntsis.Seamless tooj liab kav yog corrosion-resistant thiab high-temperature resistant. Vim lub seamless tooj liab yeeb nkab muaj ib tug tiaj tus nto thiab tsis muaj vuam cov ntsiab lus, nws muaj zoo corrosion kuj thiab kub kuj. Cov kav dej zoo tib yam tooj liab muaj cov ntsiab lus vuam thiab muaj kev cuam tshuam rau corrosion thiab kub kub.
