Cov ntaub ntawv qhia txog ASTM A312 steel kav
Cov ntaub ntawv qhia txog ASTM A312 steel kav
ASTM A312 yog tus qauv tseem ceeb rau austenitic stainless hlau raj (seamless, welded, txias- ua haujlwm) siv nyob rau hauv siab - kub / corrosive ib puag ncig. Nws npog cov ntaub ntawv qib xws li TP304 / L thiab TP316 / L, thiab tsim nyog rau kev lag luam xws li petrochemical, zaub mov, thiab tshuaj. Cov txheej txheem no qhia txog cov txheej txheem tsim khoom, kev sim cov txheej txheem (tensile, flattening), qhov ntev (NPS 1/8 "mus rau 30" +), thiab yuav tsum tau cov ntaub ntawv kom huv si thiab tsis muaj oxide nplai kom ntseeg tau. Nws lav lub zog, ductility, thiab corrosion kuj, yog li muab kev txhim khu kev qha txawm nyob rau hauv hnyav hnyav.
ASTM A312 yeeb nkab yog dab tsi?
ASTM A312 yeeb nkab yog dav dav - lub hom phiaj stainless hlau yeeb nkab dav siv hauv ntau yam lag luam. Nws txoj kab uas hla ntawm 1/8 nti mus rau 30 ntiv tes, thiab nws cov phab ntsa tuab ntawm SCH 10S txog SCH 80S. Cov khoom siv feem ntau yog TP304/304L thiab TP316/316L.
Sab nraud txoj kab uas hla: 10.3mm-609.6mm
Phab ntsa Thickness: 0.2mm-60mm
Ntev: 5-12m lossis customized raws li kev thov
Daim ntawv thov: Tsawg- kua siab, dej, roj, roj kav, boiler engineering piping, thiab lwm yam.
Cov txheej txheem ntxiv: Plain lossis threaded kev twb kev txuas (nrog lub qhov (socket) lossis bevel, nrog lub hau yas), kev sim hydrostatic, eddy tam sim no kuaj, infrared thermal tsom xam
Kev kho deg: ci ntsa iab, pickling, sandblasting lossis passivation
Delivery Condition: Kub dov, txias kos
