Galvanized steel kav, raws li cov kav dej welded, yog coated nrog ib txheej zinc ntawm lawv qhov chaw los tiv thaiv xeb thiab xeb. Txhua lub yeeb nkab yog 6 meters ntev. Muaj ob hom galvanized kav: kub-dip galvanized thiab electro-galvanized (tseem hu ua txias-dip galvanized).
Weight Coefficients ntawm Galvanized Steel Pipes
Nominal Phab Ntsa Thickness (mm): 2.0, 2.5, 2.8, 3.2, 3.5, 3.8, 4.0, 4.5
Coefficient Parameters (c): 1.064, 1.051, 1.045, 1.040, 1.036, 1.034, 1.032, 1.028
Lus Cim: Cov khoom siv hluav taws xob ntawm cov hlau yog cov cim tseem ceeb uas ua kom nws qhov kev pabcuam zaum kawg (cov khoom siv tshuab), uas tau txiav txim siab los ntawm cov hlau cov tshuaj muaj pes tsawg leeg thiab kev kho cua sov. Nyob rau hauv cov qauv steel yeeb nkab, raws li cov kev xav tau sib txawv, tensile zog (lub zog tensile, yield zog los yog yield point, elongation), nrog rau hardness, toughness indicators, thiab high / low-temperature ua tau zoo raws li thov los ntawm cov neeg siv, yog teev.
Steel Qib: Q215A; Q215B; qw 235a;. q235 ib
Kev ntsuas qhov ntsuas siab (Mpa): 3Mpa rau D10.2-168.3mm; 5Mpa rau D177 8-323.9mm
Ntau cov kauj ruam ntawm Galvanized Steel Pipes
Cov txheej txheem ntws yog raws li nram no: cov yeeb nkab dub → alkaline ntxuav → dej ntxuav → kua qaub ntxuav → yaug nrog dej huv → dipping hauv tus neeg sawv cev → ziab → kub-dip galvanizing → tshuab sab nraud → tshuab sab hauv → cua txias → dej txias → passivation → yaug nrog dej → tshuaj xyuas → hnyav → warehousing.
