NTU 3 hom, cov lus qhia tshwj xeeb, cov yam ntxwv thiab siv cov kav hlau steel

1. Raws li cov taub sab nraud ntawm cov yeeb nkab steel
Capillary: 10 hli lossis tsawg dua
Tube me me me me: 10.3 ('(') - 102 (3 '/ ") hli
Nruab Nrab Dia Hlau Tube: 114 (4 ") - 508 (20") lossis 660 (20 ") hli
Txoj kab uas txoj kab uas hla loj: 508 (lossis 660) hli lossis ntau dua
2. Raws li qhov sib piv ntawm cov hlab yeeb thiab phab ntsa tuab
Feem ntau, lawv tuaj yeem sib txawv los ntawm cov tshuaj tsw qab no:
Qeb: Txoj kab uas hla / Ntsa Thickness, Phab Ntsa Thickness / Inch
-} tuab phab ntsa yeeb nkab yeeb nkab<5.5 >0.18
Tuab - walled kav 5.5-0.0 0.18-0.12
Txheem raj 9.1-20 0.12-0.05
Nyias -} wallted leeg 20.1-50 0.05-0.02
Extra-thin wall tube >50 <0.02
