A516 Qib 70, raws li cov pa roj carbon steel rau nruab nrab - thiab qis - qhov kub siab ntawm cov hlab ntsha raws li ASTM / ASME cov qauv, muaj kev pom zoo tsim kev pabcuam kub ntawm -29℃txog 343℃. Kev cuam tshuam -certified Gr. 70N tuaj yeem txuas mus rau -45 degree, nrog luv luv-lub sij hawm siab kub siab tsis tshaj 538℃. Kev pabcuam ntev yog pom zoo kom tsis txhob siab tshaj 343 degree.
Txhawm rau yuav cov hlau phaj, thov mus saib hauv lub vev xaib hauv qab no.

I. Tej yam uas siv tau qhov kub thiab txias
Hauv kev coj ua engineering thiab kev siv code, nws feem ntau lees txais tias:
A516 Qib 70 yog tsim rau kev ua haujlwm kub ntawm kwv yees li -29℃txog 343 degree.
Tshwj xeeb:
- Tsawg- txog - nruab nrab qhov kub thiab txias (ib ncig -20℃):Qhov no sawv cev rau thaj tsam kev pom zoo rau A516 Qib 70 steel.
- Nruab nrab kub ntau (ambient txog 425 degree):Ntev ntev - lub sij hawm engineering validation qhia kev ruaj khov.
II. Cov yam ntxwv ua tau zoo ntawm qhov sib txawv ntawm qhov kub thiab txias
Tsawg kub ntau (tsawg dua lossis sib npaug rau -29 degree)
Rau qis- daim ntawv thov kub, Gr.70N steel uas tau dhau qhov kev ntsuam xyuas yuav tsum tau muab, nrog rau cov ntaub ntawv qhia txog hluav taws xob ntawm -20℃/-45℃muab.
Rau cov xwm txheej cryogenic hauv qab -60 degree, hloov nrog 9% Ni steel lossis A537 Class 1 yog pom zoo.
Nruab Nrab Kub Kub (-29 ° C txog 343 ° C)
Qhov kev pabcuam zoo tshaj plaws rau cov khoom siv, nrog lub zog tawm los Ntau dua lossis sib npaug ntawm 260MPa thiab tensile zog 485-620MPa. Weldability zoo heev thiab qaug zog tsis kam.
Haum rau cov hlab ntsha loj xws li petrochemical cia tso tsheb hlau luam, chav kav dej, boiler nruas, thiab nruab nrab - siab cais.
Siab -Qhov Kub Kub (343℃~ 538 degree)
Lub zog zuj zus degrades saum 343℃nrog nce creep kev pheej hmoo.
538℃yog luv luv -lub sij hawm siab tshaj kub; Kev ua haujlwm ntev ntev ntawm qhov kub thiab txias yog txwv tsis pub.
Rau siab -kub / siab- siab, ua ntej chromium-molybdenum tshav kub- resistant alloys xws li 12Cr1MoV lossis SA-387 Gr.91.
III. Cov txheej txheem kev xaiv kub thiab kev yuav khoom
Qhia qhov ntsuas kub tsim
Gr.70N yuav tsum raug xaiv rau qhov kub thiab txias hauv qab -29 degree, nrog rau kev pom zoo rau cov kev xav tau ntawm lub zog (feem ntau ntau dua lossis sib npaug rau 27J).
High -Kev Ntsuas Kub
Ua kom muaj zog decay suav rau qhov kub siab tshaj 343 degree, los yog hloov ncaj qha nrog cov cua sov-cov qib steel resistant.
Kev lees txais
Thov cov ntaub ntawv pov thawj, cov ntawv ceeb toom cuam tshuam, thiab cov ntaub ntawv kho cua sov kom ntseeg tau tias muaj kev sib raug zoo nrog kev ua haujlwm kub.
Vuam Compatibility
Cov txheej txheem vuam yog cov paub tab nyob rau hauv qhov qis - mus rau - nruab nrab qhov kub thiab txias, tsis tas yuav tsum muaj qhov tshwj xeeb preheating. Tswj qhov kub ntawm qhov sib cuam tshuam thaum mus txog qhov ntsuas kub siab.
IV. Hom Kev Siv Kub Kub Sib Tw
- Atmospheric/Medium-Pressure Storage Tanks: -20℃to 200 degree, standard A516 Gr.70 txaus
- Cryogenic LPG Cia Tank: -40℃rau -10 degree, siv Gr.70N
- Boiler Nruas / Chav Piping: 250℃txog 340 degree, qhov kev xaiv zoo tshaj plaws nyob rau hauv cov qauv kub
- High-Temperature Heat Exchange Equipment: >343 degree, tsis pom zoo; hloov nrog cov cua sov-resistant steel
V. Summary
Tus qauv kev nyab xeeb kub ntau rau A516 Qib 70 steel yog -29℃mus rau 343 degree, txuas ntxiv mus rau -45℃rau qis-kub daim ntawv thov (Gr.70N), nrog rau lub sij hawm luv luv high-temperature txwv ntawm 538℃. Thaum xaiv, ua qhov tseem ceeb tsim qhov kub thiab txias thaum koom nrog cov ntawv pov thawj cuam tshuam thiab kev kho cua sov kom ntseeg tau tias muaj kev nyab xeeb thiab ruaj khov ntawm cov hlab ntsha siab thoob plaws hauv lawv lub neej.
Yuxin Steel muaj ntau hom phaj qib. Yog tias koj tsis paub meej txog kev xaiv cov hlau phaj tsim nyog,thov qhia koj cov kev xav tau. Peb muab cov kev daws teeb meem customized.
