Txhim khu kev ruaj ntseg Armor rau nruab nrab & qis -Tsuas Kub Siab Vessels
A516 Gr.70 (tseem hu ua ASME SA516 Gr.70) yog cov pa roj carbon steel phaj tshwj xeeb tsim los rau cov hlab ntsha siab ua haujlwm hauv nruab nrab thiab qis- qhov kub thiab txias. Nws yog dav siv nyob rau hauv:
- Petrochemical reactors thiab cia tank
- LNG cia thiab khoom siv thauj mus los
- Gas tuav thiab kub exchangers
- Muaj boilers
Vim li cas cov engineers ntseeg A516 Gr.70?Vim tias nws muab peb qhov kev lav phib xaub tseem ceeb rau koj qhov project nkoj siab:
| Cov khoom tseem ceeb | Nws txhais li cas rau koj qhov project |
| Siab tensile zog (485-620 MPa) | Txaus kev nyab xeeb margin nyob rau hauv lub siab tsim. Txawm tias thaum lub sij hawm luv luv - lub sij hawm siab spikes, cov ntaub ntawv muab ib tug buffer tiv thaiv kev puas tsuaj rupture. |
| Zoo heev low -kub toughness (27J @ -30 degree) | Txo qhov kev pheej hmoo ntawm pob txha tawg thaum cov cuab yeej ua haujlwm hauv thaj chaw txias (Northern Europe, Canada, Russia) lossis ua haujlwm qis -kub xov xwm (LNG, kua ammonia). |
| Weldability zoo (CE Tsawg dua lossis sib npaug rau 0.43, raug 0.3) | Tsawg preheating yuav tsum tau, tsawg weld tawg, txo nqi rework. Koj lub rooj cob qhia tau txais cov txheej txheem tsim kom yooj yim dua. |
Los ntawm LNG module tej yaam num nyob rau sab hnub tuaj Asia mus rau petrochemical cog kev nthuav dav nyob rau hauv Middle East, peb tau pab cov neeg siv khoom xaiv cov khoom siv, kev tshuaj xyuas ntawv pov thawj, kev hloov pauv thaum muaj xwm txheej ceev, thiab kev txiav me me.
Koj tau txais dab tsi thaum koj xaj los ntawm peb:
Clear traceability los ntawm steel zeb rau shipping chaw nres nkoj
Mill daim ntawv pov thawj (EN 10204 Hom 3.1 lossis 3.2 nrog rau thib peb -tus neeg tim khawv)
Pab neeg ua haujlwm uas nkag siab txog ASME code cov cai

Strength (lub zog tensile & yield zog)
Lub zog tensile zoo ib yam li "qhov siab tshaj plaws load-bearing peev" ntawm steel phaj. Nws ua kom ntseeg tau tias koj lub nkoj siab muaj kev nyab xeeb txaus nyob rau hauv lub siab tsim. Txawm hais tias nws ntsib qhov kev npaj txhij txog luv luv - lub sij hawm siab siab, muaj qhov chaw tsis zoo los tiv thaiv kev puas tsuaj loj.
Lub zog tawm los yog ntau zoo ib yam li "kev ua haujlwm zoo li qub". Qhov sib npaug ntawm lub zog tsim ntawm A516GR70 ua rau nws muaj peev xwm thauj khoom txaus- cov kabmob muaj peev xwm thaum ua kom haum rau kev khoov txias thiab daim ntawv dov. Qhov no tuaj yeem txo qhov kev ua haujlwm nyuaj thiab cov khoom pov tseg thaum lub sijhawm tsim cov thooj voos kheej kheej thiab lub taub hau, ua rau kev ua haujlwm hauv kev ua haujlwm ua haujlwm zoo dua.
Tsawg-kub toughness
Rau cov khoom siv nyob rau hauv cov cheeb tsam txias (xws li Northern Europe, Canada, Russia) los yog nyob rau hauv qis - kub xov xwm (xws li LNG, kua ammonia), lub toughness ntawm cov khoom yog qhov tseem ceeb tshaj plaws. Qhov zoo tshaj plaws qis-kub qhov cuam tshuam tus nqi ntawm A516GR70 zoo li txhaj tshuaj "tiv thaiv-cov tshuaj tiv thaiv khov" rau hauv koj cov khoom siv.
Nws tuaj yeem txo qhov kev pheej hmoo ntawm kev tawg sai sai ntawm cov khoom siv vim muaj kev ntxhov siab thaum ua haujlwm ntawm qhov kub thiab txias, uas yog qhov tseem ceeb qhia txog kev nyab xeeb. Xaiv cov ntaub ntawv uas tsim nyog toughness yog ib qho tseem ceeb tshaj plaws hauv paus rau koj kom dhau qhov kev tshuaj xyuas nruj nruj thiab tau txais daim ntawv tso cai ua haujlwm.
Weldability (Carbon Equivalent Control)
Kev ua tau zoo welding zoo txhais tau tias:
Tsis tshua muaj kev tawg yooj yim: txo qis qhov tshwm sim ntawm cov kab nrib pleb los yog kub tawg tshwm sim hauv tshav kub - cuam tshuam thaj tsam ntawm cov vuam seam, yog li txo cov nqi ntawm cov nqi rov ua dua thiab tshuaj xyuas.
Ntau tus phooj ywg rau cov txheej txheem vuam: Nws tso cai rau ntau qhov kev sib txuas ntawm vuam, thiab cov txheej txheem ua ntej ua ntej vuam yuav qis dua, yog li ua kom yooj yim cov txheej txheem thiab ua kom lub voj voog tsim.
Weld quality is more stable: It is easier to obtain welds that are dense, have good strength and toughness compatibility, ensuring the overall integrity and long-term reliability of the equipment.
