Dab tsi yog 16MnDR Tsawg-Tub Kub Hlau Yeeb Nkab?
16 MnDRyog qib qis- alloy steel txhais los ntawm Suav tus qauvGB/T 3531rau qis-kub siab cov hlab ntsha. Nws yog tsim los rau cov khoom siv thiab cov kav dej uas ua haujlwm ntawm sub- xoom kub, suav nrog LPG cia, kev ua ethylene thiab cov nroj tsuag sib cais cua. Tsis zoo li cov qauv hlau zoo tib yam, 16MnDR tswj cov kev cuam tshuam ruaj khov rau-40 degree, tiv thaiv cov pob txha tawg uas feem ntau hem cov pa roj carbon steel hauv kev pabcuam cryogenic.
Chemical Composition thiab Metallurgical Design
Lub npe "16MnDR" qhia txog cov ntsiab lus nominal carbon ntawm 0.16% thiab manganese ntau ntawm 1.20% txog 1.60%. Manganese ntxiv dag zog rau cov ferrite-pearlite matrix thiab txo cov ductile- mus rau -nkig hloov kub yam tsis muaj tus nqi siab ntawm nickel-raws li alloys. Cov kab ntxiv ntawm nickel qee zaum tau teev tseg los txhim kho sub{10}}zero toughness ntxiv. Cov hlau yog tag nrho deoxidized, los yog tua, nrog txhuas kom ua tau zoo thiab homogeneous grain qauv, uas yog lub hauv paus tseem ceeb tom qab nws zoo heev zog nqus nyob rau hauv tej yam loading.
Mechanical Properties ntawm 16MnDR
| Khoom | 16MnDR Requirement |
|---|---|
| Yield zog (min., t Tsawg dua lossis sib npaug li 16 hli) | 345 MPa rau |
| Tensile zog | 490-620 MPa |
| Impact test kub | -40 degree |
| Yam tsawg kawg nkaus lub zog (avg., longitudinal) | 34 J |
Fabrication, Vuam thiab Kev kho cua sov
Cov khoom tsim los ntawm 16MnDR yuav tsum yognormalizedlos kho cov pearlite-ferrite qauv thiab tshem tawm cov coarse nplej tsim thaum kub dov. Vuam yuav tsum tau tsawg- hydrogen consumables thiab nruj me ntsis tswj preheat kub kom tsis txhob txias tawg nyob rau hauv lub tshav kub- cheeb tsam cuam tshuam. Rau cov ntu hnyav, tom qab-weld kho cua sov yog cov qauv kev coj ua kom rov qab muaj zog thiab txo qis kev ntxhov siab ua ntej lub nkoj nkag mus rau kev pabcuam cryogenic.
Tej kev siv
LPG thiab propane cia tanks thiab spheres
Ethylene cog cov seem txias thiab cov cua kub sib txawv
Cua cais cov thawv txias thiab cov kav dej cryogenic
Ammonia thiab methanol synthesis khoom
Tsawg- cov hlab ntsha kub siab rau kev ua tshuaj lom neeg
Kev Tswj Xyuas Zoo thiab Kev Tshawb Fawb
Rau cov kev pabcuam tseem ceeb ntawm cov hlab ntsha, 16MnDR daim hlau thiab cov kav dej yog raug rau 100% kev kuaj ultrasonic kom pom cov laminations sab hauv lossis kev suav nrog. Charpy V-kev ntsuas qhov cuam tshuam ntawm -40 degree, kev ntsuam xyuas tensile thiab hardness kev soj ntsuam yog ua los xyuas kom meej raws li GB/T 3531 cov cai ua ntej xa khoom.
Cov lus nug nquag
Puas yog 16MnDR sib npaug rau ASTM A333 Qib 6?
Ob cov ntaub ntawv muaj tshuaj zoo sib xws, tab sis 16MnDR yog tus qauv ntawm lub nkoj siab (GB / T 3531), thaum ASTM A333 Qib 6 yog qhov qis -kub piping txuj. Txhua tus yuav tsum tau teev tseg raws li tus qauv tsim qauv.
Qhov kev pabcuam siab tshaj plaws yog dab tsi?
16MnDR raug ntsuas rau kev pabcuam txuas ntxiv mus txog 350 degree, txawm hais tias nws cov nqi engineering nyob hauv sub-zero range down to -40℃.
16MnDR puas tuaj yeem siv rau LNG thauj?
Tsis yog LNG kev pabcuam yuav tsum -162 degree, uas xav tau 9% nickel steel lossis austenitic stainless hlau; 16MnDR tsis haum ntawm qhov kub ntawd.
"DR" txhais li cas hauv 16MnDR?
DR sawv cev rau "DiWen RongQi", lub ntsiab lus Suav rau qis -kub siab lub nkoj, qhia txog qib kev pabcuam.
Puas yog 16MnDR yuav tsum tau kuaj ultrasonic?
Yog lawm. Rau lub luag haujlwm tseem ceeb ntawm cov hlab ntsha, 100% kev tshuaj xyuas ultrasonic yuav tsum tau lav kev ywj pheej los ntawm kev tsis xws luag.
Yam khoom siv vuam siv tau pom zoo?
Tsawg-hydrogen electrodes los yog cov xov hlau uas muaj kev tswj tau diffusible hydrogen, ua ke nrog preheat ntawm kwv yees li 100-150℃rau cov seem tuab.
