Admiralty Brass Tubes - Kev Paub

Admiralty tooj dag yog tooj liab -zinc alloy nrog me me ntxiv ntawm tin thiab arsenic - cov arsenic raug ntxiv txhob txwm tshaj tawm los tiv thaiv dezincification corrosion. Nws lub npe classic yog C44300 (ASTM / UNS), nrog rau cov npe European CuZn28Sn1 (EN 12451). Admiralty brass tube yog qhov ntev - sawv ntsug qhov tshwj xeeb rau chav condenser tubing thiab cua sov- kev pabcuam pauv hauv kev lag luam marine, fais fab thiab txheej txheem, thiab nplooj ntawv no teev cov ntaub ntawv, cov qauv thiab qhov ntau thiab tsawg uas koj yuav tsum tau qhia kom raug.

Ntsiab Cai

Admiralty tooj dag C44300=Cu 70–73%, Sn 0.9–1.2%, As 0.02–0.06%, sib npaug zinc; arsenic inhibits dezincification.
Cov qauv kev tswj hwm: ASTM B111 / ASME SB-111 (C44300), BS 2871 Tshooj 3 CZ111, EN 12451 CuZn28Sn1As, JIS H3300 C4430.
Nws muaj qhov ua tau zoo tshaj plaws ntawm cov khoom siv tooj dag rau cov tshuaj sulfur thiab cov dej tsis huv, ntawm tus nqi qis dua cupronickel.
Cov ntawv thov ib txwm: cov raj xa dej, lub tshuab tso dej tso cua sov, cov khoom siv hluav taws xob refinery, cov dej hiav txwv thiab cov dej tsis huv - kev pabcuam dej.

Admiralty Brass yog dab tsi?

Admiralty tooj dag yog 70/30- hom tooj dag (kwv yees li 70% tooj liab, 30% zinc) hloov nrog li 1% tin thiab tswj arsenic ntxiv ntawm 0.02-0.06%. Lub tin txhim kho corrosion kuj nyob rau hauv sulphur-cov kabmob thiab cov dej tsis zoo; arsenic suppresses dezincification, xaiv leaching ntawm zinc uas tsis muaj zog tooj dag zoo tib yam hauv dej hiav txwv thiab kev pabcuam brackish. Qhov kev sib xyaw ua ke no ua rau cov neeg qhuas qhuas cov tooj dag muaj zog ntau dua li 70/30 tooj dag nyob rau hauv ib puag ncig hnyav thaum tseem pheej yig dua li cupronickel alloys.

Kev tswj hwm tus qauv thiab sib npaug

Admiralty tooj dag raj yog tsim seamless rau cov qauv hauv qab no:

Mechanical thiab Physical Properties

Yam khoom tensile rau annealed (O) thiab lub teeb -tws tempers ntawm C44300 raj:

Tensile zog: 310 MPa yam tsawg kawg nkaus (ASTM B111, annealed mob).
Elongation: 45% yam tsawg kawg nkaus hauv 50 mm rau annealed raj.
Hardness (Rockwell F, annealed): kwv yees li 75 HRF siab tshaj plaws.
Zoo ductility thiab formability, tso cai dov - nyob rau hauv thiab flaring nyob rau hauv condenser raj ntawv.

Kev sib xyaw ua ke ntawm cov thermal conductivity zoo, ductility thiab corrosion kuj yog vim li cas admiralty tooj dag tau tseem yog cov khoom siv condenser rau ntau tshaj ib puas xyoo.

Corrosion Resistance thiab Application Environments

Admiralty tooj dag yog xaiv qhov twg cov dej txias yog txhoj puab heev tab sis tsis heev saline:

Chav tsev condensers thiab nto condensers (lub zog tsim thiab marine propulsion).
Feedwater heaters thiab roj coolers.
Thaum tshav kub kub exchangers nyob rau hauv refineries, petrochemical thiab txheej txheem cov nroj tsuag.
Kev pab cuam nrog dej hiav txwv, dej brackish, dej qias neeg dej thiab sulphur-compound- dej bearing.

Qhov twg dej txias yog saline heev los yog chlorinated, cupronickel (xws li C70600 / C71500) yog qhov kev hloov kho dua tshiab; admiralty tooj dag tseem yog qhov kev lag luam thawj zaug rau qhov chaw nruab nrab.

Tempers: annealed (O), temper -annealed (TA) thiab raws li -manufactured (M) rau ASTM B111.

FAQ

Dab tsi yog qhov txawv ntawm admiralty tooj dag thiab txhuas tooj dag?

Admiralty tooj dag (C44300) ntxiv ~ 1% tin + arsenic; aluminium brass (C68700) ntxiv ~ 2% txhuas + arsenic. Aluminium tooj dag muaj zog dua thiab zoo dua yaig kuj nyob rau hauv siab -ceev seawater, thaum admiralty tooj dag yog nyiam rau nruab nrab, sulphur - bearing dej.

Vim li cas arsenic ntxiv rau admiralty tooj dag?

Arsenic (0.02–0.06%) yog txhob txwm dezincification inhibitor. Yog tsis muaj nws, zinc leaches xaiv los ntawm cov hlau alloy hauv dej hiav txwv thiab dej brackish, tawm hauv cov txheej txheem tooj liab tsis muaj zog.

Tus qauv twg yog siv rau cov raj condenser thoob ntiaj teb?

ASTM B111 (nrog rau ASME SB-111 code version) yog qhov tseem ceeb thoob ntiaj teb kev qhia tshwj xeeb rau seamless condenser thiab tshav kub exchanger raj, suav nrog C44300 admiralty tooj dag.

Puas yog admiralty tooj dag raj siv tau rau cov kav dej kav dej?

Admiralty tooj dag yog engineered rau cua sov- kev pab cuam pauv, tsis potable - dej faib. Rau cov kav dej, siv tus qauv tooj liab raj rau ASTM B88 lossis tooj dag fittings raws li cov dej hauv zos - cov cai tswj dej.
