- ASTM A182 Standard Specification rau Forged los yog Rolled Alloy-Steel Yeeb Nkab Flanges, Forged Fittings, thiab li qub thiab qhov chaw rau kev pab kub kub
Thaum piv rau 316 stainless hlau tsis tu ncua, ASTM A182 F316L flanges muaj kev tiv thaiv corrosion ntau dua thiab muaj peev xwm vuam txij li "L" sawv cev rau cov ntsiab lus carbon tsawg. Cov flanges no yog austenitic stainless hlau. Raws li ASTM A182 F316L flange specifications, cov tshuaj muaj xws li chromium (16–18 feem pua), npib tsib xee (10–15 feem pua), molybdenum (2–3 feem pua), thiab manganese (2 feem pua). Cov Cheebtsam no pab txhawb rau F316L flange lub zog muaj zog thiab muaj peev xwm tiv taus corrosion.

Kev tsim cov txheej txheem rau ASTM A182 F316L flanges suav nrog forging, machining, thiab kho cua sov. Ua ntej kev tsim cov flanges, cov khoom zoo stainless hlau billets lossis cov tuav uas ua raws li ASTM A182 F316L cov qauv tshuaj muaj pes tsawg leeg yuav tsum raug xaiv. Cov pob zeb uas tau xaiv yog ces rhuab thiab forged siv qhib tuag forging los yog kaw tuag forging txheej txheem. Lub flange tau lees tias yog qhov loj, zoo, thiab kev ncaj ncees los ntawm forging, txhim kho nws cov khoom siv zoo. Lub flange yuav tsum dhau los ntawm cov txheej txheem machining xws li tig, milling, drilling, thiab tapping thaum nws tau forged. Rau kev sib txuas zoo flange, nws yog ib qho tseem ceeb los xyuas kom meej qhov ntev, qhov chaw du, thiab kev sib raug zoo ntawm lub qhov ntsia hlau. Txhawm rau txhim kho cov khoom zoo ntawm F316L flanges, cov txheej txheem kev kho cua sov zoo li annealing lossis kev daws teeb meem tom qab quenching thiab tempering yuav raug siv. Tsis tas li ntawd, residual tensions tsim thaum lub sij hawm forging thiab machining yog relieved los ntawm kev kho cua sov. Cov khoom tsim F316L flanges tom qab ntawd raug kuaj xyuas nruj, suav nrog kev tshuaj xyuas qhov muag thiab qhov ntev, tsis muaj kev puas tsuaj (siv cov duab hluav taws xob lossis ultrasonic imaging, piv txwv li), thiab kev sim tshuab (kev cuam tshuam, tensile, thiab hardness test). Qhov no lav qhov flanges 'zoo thiab ua raws li cov qauv xav tau.
