A333 gră LTCS cov yeeb nkab yeeb nkab
ASTM A333 Gr.6 yog haiv neeg Asmeskas rau kev sim thiab cov ntaub ntawv (ASTM) tus qauv rau Cryogenic daim ntawv thov rau Cryogenic Daim Ntawv Thov (ASTM A333 / A333m). ASTM A333 GR.6 yog tus qauv rau seamless yeeb nkab rau cry - kev sib pauv, thiab lwm yam nkoj siab xav txog nkoj.
Nws cov khoom tseem ceeb muaj xws li:
Tsawg - kub todlemness: kev ua kom zoo dua thiab kev kho cua sov kom tsis txhob tawg txias, lav kom muaj kev nyab xeeb nyob rau ib puag ncig huab.
Nickel - ywj pheej tsim: ua ntej {}}}}}}}}}} {{}} altelo cov yam ntxwv.
A333 gr 6 kub - rolled steel kav
A333 GR6 Seamless Cov Yeeb Nkab Tshwj Xeeb
Cov Khoom Qhia Khoom:
Txheej txheej Incat 21.3mm ~ 762mm, Phab Ntsa Thickness 2.0 hli ~ 140mm
Yuav tsum tau kho cua sov yuav tsum muaj rau 333 gr 6 raj:
1. Li no ib txwm ua tiav 815 degree.
2. Li qub tshaj 815 degree, ces tempering.
3. Kub txoj kev sib haum ntawm 845-945 degree, ces cua txias txias saum 845℃(siv tsuas yog mus rau kev ua yeeb yam hlab).
4. Tempering tom qab kev ua.
5. Quenching saum toj no 815 degree, ces tempering.
Tshuaj lom neeg siv tshuaj thiab alloy tsim
- Cov khoom sib xyaw ua ke (Pawg ib xees)
| lub ntsiab | C | Mn | Si | P | S |
|---|---|---|---|---|---|
| zoo siab | Tsawg dua los yog sib npaug rau 0.30% | 0.29~1.06% | Tsawg dua los yog sib npaug rau 0.40% | Tsawg dua los yog sib npaug rau 0.025% | Tsawg dua los yog sib npaug rau 0.025% |
Cov pa roj carbon tsawg thiab tsis tshua muaj kev tswj hwm ntawm cov pa roj carbon, phosphorus thiab cov lus faj sulfur los txo qhov kev pheej hmoo ntawm qis qis- kub
- Alloy Qhov Cuab (kho tshiab rau 2016)
Cov ntsiab lus tshiab xws li Cr, Ni, Mo, CU, thiab lwm yam los yog sib npaug los ntawm cov khoom siv ntsuas qis thiab kub thiab txias.
Cov Cuab Yeej Siv Cov Tshuab thiab Cov yam ntxwv Tseem Ceeb
| Lus | tensile lub zog (ntau dua los yog sib npaug) | paib lub zog (ntau dua los yog sib npaug) | elongation (ntau dua los yog sib npaug) | Tsawg - kub kev poob siab kev ua haujlwm (-45 degree) |
|---|---|---|---|---|
| numic | 415 MPa | 240 MPa | 30% | Ntau dua los yog sib npaug rau 20 j (transverse qauv) |
Cov Ntawv Thov:
- Lub zog kev lag luam: Lng Liquefied Ntuj Roj Pipelines, Inter -}} txias} Cov khoom txias cia khoom thiab cov khoom xa tawm.
- Cov Khoom Siv Tshuaj: Ethylene crackers thiab polypropylene reactors, tshwj xeeb hauv cryogenic ncig piping.
- Huab av: Arctic / Antarctic roj thiab roj av, ntxiv rau hauv ultra - Cov khoom siv ntsuas hluav taws kub tsawg.
Ceev faj rau kev siv A333 Gr6 Hlau Yeeb:
- Qhov kub txwv: Nws yog qhov tseem ceeb kom txwv ntev -}} siv tau ntawm tus tsim ntawm A333 gr6 steel hlau siab dua -45℃kom tsis txhob muaj kev tsis txaus siab ntawm cov khoom siv.
- Cov txheej txheem vuam vuam: Cov khoom siv hluav taws xob qis heev yog qhov yuav tsum tau ua kom tiv thaiv kev tawg txias hauv chaw weld.
- Corrosion tiv thaiv: Ntxiv cov txheej sab nraud lossis kev tiv thaiv Cathodic yog yuav tsum tau thaum nthuav tawm cov chaw ntub dej lossis kev xeb lossis thaj chaw ua xeb.
