ASTM A312 TP316/316L Dual -Certified Stainless Hlau Yeeb

TP316/316L Dual -Certified Stainless Steel Tubes yog dab tsi?

TP316/316L dual{2}}cov kav hlau tsis muaj ntawv pov thawj ua tau raws li ASTM A312/ASME SA312 cov qauv thiab ib txhij ua tau raws li cov kev cai ntawm qib TP316 thiab TP316L. Cov ntsiab lus ntawm carbon yog ruaj khov nyob rau hauv tsawg dua los yog sib npaug li 0.035% -0.08%, nrog 16.0-18.0% chromium, 10.0-14.0% nickel, thiab 2.00-3.00% molybdenum. Lub zog tensile ncav cuag Ntau dua lossis sib npaug rau 485 MPa (TP316L) / Ntau dua lossis sib npaug rau 515 MPa (TP316), thiab tus nqi PREN yog ntau dua lossis sib npaug rau 32. Cov kav dej no muab cov khoom ntawm ob qib, dhau mus kuaj nruj, thiab tau muab cov ntawv pov thawj pov thawj.

 

Peb muab TP316/316L dual- ntawv pov thawj stainless hlau kav tag nrho raws li ASTM A312 / ASME SA312 tus qauv, muaj nyob rau hauv ob qho tib si seamless thiab ncaj seam welded hom. Specifications npog txheej diameters los ntawm 1/8 nti (3.18 mm) mus rau 48 nti (1219 mm), nrog phab ntsa thickness xws li SCH 5S mus rau SCH 160 thiab XXS series. Cov kev xaiv ntev muaj xws li 4-12 m random lengths, 15-24 ft ib qhov ntev random, lossis customized ntev raws li qhov kev thov. Deg finishes muaj xws li pickling thiab passivation, ci annealing, thiab mechanical polishing. Peb kuj txhawb kev kho kom haum rau cov kev cai tshwj xeeb xws li ultra- phab ntsa nyias (tsawg dua lossis sib npaug li 0.3 hli) thiab cov kab loj loj (Ntau dua lossis sib npaug rau φ610 mm).

Txhua batch tau kuaj xyuas hydrostatic ntawm 1.5 npaug ntawm qhov tsim siab, nrog rau eddy tam sim no thiab ultrasonic tsis- kuaj kev puas tsuaj. Dimensional kam rau ua yog nruj me ntsis tswj nyob rau hauv ± 1% rau txheej kab thiab ± 10% rau phab ntsa thickness. Tag nrho cov khoom tau muab nrog EN 10204 3.1 Daim Ntawv Pov Thawj Mill Test (MTC), nrog rau thib peb-cov ntaub ntawv soj ntsuam los ntawm TÜV thiab SGS. Cov ntawv pov thawj xaiv tau los ntawm kev faib cov koom haum xws li ABS, BV, thiab DNV-GL kuj muaj, txhim kho kev ua tau zoo thiab txo cov nqi xaiv khoom.

316 vs . 316L Stainless Hlau Yeeb Nkab: Cov ntsiab lus carbon

Thawj qhov sib txawv ntawm 316 thiab 316L stainless hlau yeeb nkab yog tias 316L muaj cov ntsiab lus qis dua, nrog qhov siab tshaj plaws ntawm 0.03%, piv rau 316 qhov siab tshaj plaws ntawm 0.08%. Qhov no "Low" carbon formula ('L') txo chromium carbide nag lossis daus thaum vuam, txhim kho corrosion kuj nyob rau hauv welded kav thiab tiv thaiv rhiab heev.
