Taw qhia rau ASTM A106
ASTM A106 1yog thawj American Standard specification rauseamless carbon steel yeeb nkabtsim tshwj xeeb rau kev ua haujlwm siab - kub. Cov qauv no yog qhov tseem ceeb hauv kev lag luam uas cov kav dej yuav tsum xa cov kua dej ntawm qhov kub thiab txias tsis muaj kev cuam tshuam kev nyab xeeb lossis kev ncaj ncees. Kev nkag siab txog cov kev cai tshwj xeeb thiab kev muaj peev xwm ntawm ASTM A106 yog qhov tseem ceeb rau cov kws tshaj lij thiab cov kws tshaj lij kev muag khoom hauv cov haujlwm xws li kev tsim hluav taws xob thiab roj av refining.
Standard Scope & Cov yam ntxwv tseem ceeb
ASTM A106 (feem ntau hu ua ASME SA106) npog seamless carbon steel yeeb nkab rau siab -kev siv kub, feem ntau nyob rau hauv thaj tsam ntawm -29℃mus rau 815℃(-20℃F txog 1500℃F). Nws cov yam ntxwv txhais muaj xws li:
Seamless Kev tsim kho nkaus xwb: Ua kom lub zog zoo dua qub thiab muaj kev sib haum xeeb nyob rau hauv thermal stress thiab siab, tsis muaj longitudinal weld seam uas yuav yog qhov ua tsis tau zoo.
High -Tsub Ua Haujlwm: Cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv kho tshuab tau ua kom zoo rau kev ua haujlwm tau zoo nyob rau hauv qhov chaw kub siab.
Peb Qib Siab: Muab kev hloov pauv nrog Qib A, B, thiab C kom phim cov qauv tsim tshwj xeeb siab thiab qhov kub thiab txias.
Chemical Composition, thiab Mechanical Properties
ASTM A106 muab peb qib uas muaj zog ntau dua, nrog rauQib Byog qhov siv ntau tshaj plaws kev lag luam workhorse.
Mechanical Properties
| Qib | Tensile zog, min. | Yield zog, min. |
|---|---|---|
| A | 330 MPa (48,000 psi) | 205 MPa (30,000 psi) |
| B | 415 MPa (60,000 psi) | 240 MPa (35,000 psi) |
| C | 485 MPa (70,000 psi) | 275 MPa (40,000 psi) |
Chemical Composition (ntau tshaj % lossis ntau yam)
| Element | Qib A | Qib B | Qib C |
|---|---|---|---|
| Cov pa roj carbon (C) | 0.25 | 0.30 | 0.35 |
| Manganese (Mn) | 0.27 - 0.93 | 0.29 - 1.06 | 0.29 - 1.06 |
| Phosphorus (P) | 0.035 | 0.035 | 0.035 |
| Sulfur (S) | 0.035 | 0.035 | 0.035 |
Cov txheej txheem tsim khoom thiab cov khoom lag luam
Kev tsim khoom ntawm ASTM A106 yeeb nkab yog cov txheej txheem tswj kom ntseeg tau tias muaj kev ntseeg siab:
- Kub-Tiav Seamless: Cov txheej txheem tseem ceeb, qhov twg cov khoom siv hluav taws xob tau pierced thiab dov rau qhov loj ntawm qhov kub thiab txias, zoo tagnrho rau cov qauv loj thiab cov phab ntsa thicknesses.
- Txias -Drawn Seamless: Rau cov ntawv thov uas yuav tsum tau ua kom tiav saum npoo, nruj dua qhov ntev, thiab cov khoom siv kho kom zoo, cov kav dej tau ua tiav ntxiv los ntawm kev ua haujlwm txias - kos duab.
Cov kav dej no muaj nyob rau hauv tag nrho cov sij hawm (xws li Sch 40, 80, 160, XXS) thiab tuaj yeem muab tau rau hauv cov cua sov- kho mob (annealed lossis normalized) rau cov kev xav tau tshwj xeeb.
Cov ntawv thov siv
ASTM A106 yog cov khoom ntawm kev xaiv rau qhov tseem ceeb siab -kev pabcuam kub:
Fais fab Boilers thiab Thermal Power Plants: Rau cov kav dej, cov kav dej, thiab lwm yam siab -kub circuits.
Petrochemical Refineries: Hloov cov txheej txheem dej, hydrocarbons, thiab catalysts ntawm qhov kub siab.
Siab -Nias Chav thiab Condensate Kab: Hauv cov txheej txheem kev lag luam.
Pipelines rau Roj & Gas Transmission: Especially in sections requiring high strength and temperature resistance.
PebLEFIN STEELtshwj xeeb hauv kev tsim cov siab -kev ncaj ncees ASTM A106 seamless steel kav. Peb ua raws li cov txheej txheem tswj xyuas kom zoo, suav nrog kev sim hydrostatic, tsis yog - kev kuaj xyuas kev puas tsuaj, thiab tag nrho traceability. Peb muab tag nrho peb qib (A, B, C) thoob plaws qhov ua tiav qhov loj me, kom ntseeg tau tias peb tuaj yeem muab cov yeeb nkab zoo tagnrho rau koj qhov kev thov siab tshaj plaws - kub thiab siab - cov ntawv thov siab.
