ASTM A312 TP316L Seamless Stainless hlau yeeb nkab
Tso lus
Vim li cas cov kav hlau tsis muaj seamless siv nyob rau hauv cov ntawv thov tseem ceeb tseem ntsib cov teeb meem xau, corrosion, lossis teeb meem teeb meem -txawm tias lawv ua raws li ASTM cov qauv? Qhov tseem ceeb yog nyob rau hauv manufacturing precision, txheej txheem tswj, thiab nto zoo.
ASTM A312 TP316L seamless stainless hlau kav yog tsim los ntawm kev sib xyaw ntawm kub extrusion thiab txias txheej txheem, ua raws li cov tshuaj annealing ntawm 1050-1100 degree. Peb siv 100% PMI (Positive Material Identification), eddy tam sim no thiab ultrasonic kuaj, nrog rau kev ntsuas hydrostatic siab (10-thib ob). Tshuaj muaj pes tsawg leeg sib txawv yog nruj me ntsis tswj nyob rau hauv ± 0.5%, ua tau raws li ASTM A312 cov cai.
Nyob rau hauv cov nqe lus ntawm qhov tseeb qhov tseeb, sab nraud txoj kab uas hla ntawm ASTM A312 TP316L stainless hlau kav yog tswj nyob rau hauv ± 0.02 hli, phab ntsa thickness kam rau ua nyob rau hauv ± 0.05 hli, thiab ncaj tsawg dua los yog sib npaug zos rau 0.5 hli / m. Tom qab ci annealing, qhov nto roughness (Ra) tsawg dua los yog sib npaug rau 0.4 μm; Tom qab electropolishing, Ra<0.2 μm. These values fully comply with stringent GMP/FDA cleanliness requirements, with metal ion release controlled at ≤0.1 ppb.
TP316L seamless kav muaj ib qho ultra- cov ntsiab lus carbon tsawg (tsawg dua lossis sib npaug li 0.03%) thiab 2.0-2.5% molybdenum, muab kev tiv thaiv corrosion rau chlorides uas yog 3 mus rau 5 npaug siab dua 304 stainless hlau. Cov kav dej tuaj yeem tiv taus ntau dua 2000 xuab moos ntawm kev ntsuas ntsev tsuag yam tsis muaj xeb liab, thiab pom qhov corrosion ntawm tsawg dua 0.01 hli / xyoo hauv 5% sulfuric acid ib puag ncig. Nrog lub zog tensile Ntau dua lossis sib npaug ntawm 485 MPa thiab elongation Ntau dua lossis sib npaug li 40%, lawv tswj kev ua haujlwm ruaj khov thoob plaws qhov kub thiab txias ntawm -270℃txog 450 degree.
Welded piping yav tas los siv los ntawm cov nroj tsuag tshuaj tsim crevice corrosion thiab pib xau tom qab tsuas yog rau lub hlis ntawm kev pabcuam. Tom qab hloov mus rau TP316L seamless kav tsim los ntawm GNEE, lub neej kev pab cuam ntawm cov kav dej tau txuas mus rau 36 lub hlis; qhov no tsis yog tsuas yog txo tus nqi txij nkawm los ntawm 70% tab sis kuj tshem tawm tag nrho cov kev tsis txaus siab los ntawm cov khoom siv tsis ua haujlwm.

Dab tsi yog qhov txawv ntawm ASTM A312 TP316L thiab 316L?
TP316L yog ib qib tshwj xeeb los ntawm ASTM rau seamless lossis welded stainless hlau tubing (qhov "TP" sawv cev rau "Tube / Yeeb Nkab"); Nws yog tus cwj pwm los ntawm cov ntsiab lus carbon tsawg (tsawg dua lossis sib npaug li 0.03%) thiab, piv rau qib 316 tus qauv, muaj kev sib txuas zoo dua thiab kev tiv thaiv corrosion. Hauv qhov sib piv, 316L yog qhov dav dav - lub hom phiaj qis - carbon alloy qib, feem ntau siv hauv kev tsim cov phaj, fasteners, thiab cov khoom siv.
