1. Dab tsi yog Cov Kev Siv Feem Ntau ntawm C22000?
Cov cheeb tsam tseem ceeb ntawm kev thov:
Cov kav dej uas muaj peev xwm, fittings, thiab valve stems (tiv thaiv corrosion los ntawm dej tshiab, chlorine, thiab ntxhia deposits; ua raws li cov qauv kev nyab xeeb zaub mov zoo li NSF / ANSI 61).
Cov kav dej muaj rau cov uas tsis yog -oxidizing acids, roj, thiab cov roj (cov ntsiab lus zinc tsawg txo qhov kev pheej hmoo ntawm dezincification, ua kom ntev - lub neej kev pab cuam).
Screws, txiv ntseej, bolts, thiab ntxhua khaub ncaws rau marine, architectural, thiab industrial siv (corrosion-resistant thiab ductile, haum rau sab nraum zoov lossis qhov chaw ntub dej).
Cov khoom siv kav dej (faucet Cheebtsam, cov yeeb nkab txuas) vim nws qhov sib haum nrog dej thiab tsis kam ua kom tarnish.
Kho kom zoo nkauj luas, qhov rooj tuav, railings, thiab kos npe (nrog ib tug sov reddish-gold hue uas patinates rau ib tug nplua nuj bronze xim nyob rau hauv lub sij hawm, ua kom zoo nkauj tus nqi).
Architectural cladding, ru tsev, thiab ornamental metalwork (malleable rau intricate shaping thiab check tiv thaiv atmospheric corrosion).
Lub nkoj fittings, cov khoom siv hauv lub nkoj, thiab cov khoom siv hauv hiav txwv (tiv thaiv cov dej qab ntsev zoo dua li cov qauv tooj dag, ua rau nws zoo tagnrho rau kev siv ntug hiav txwv lossis dej hiav txwv).
Underwater fasteners thiab piping (tsawg degradation ntawm seawater thiab biofouling).
Thaum tshav kub kub exchanger raj thiab condenser Cheebtsam (zoo thermal conductivity thiab corrosion kuj nyob rau hauv nruab nrab-kub ib puag ncig).
Cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob (cov khoom siv hluav taws xob nruab nrab ua ke nrog kev tiv thaiv corrosion, haum rau cov ntawv siv hluav taws xob tsawg tsawg).
2. Cov Qauv Txheej Txheem rau C22000 yog dab tsi?
1. American Standards (Lub Ntiaj Teb Kev Lag Luam Dominant)
ASTM B111/B111M: Standard Specification rau tooj liab thiab tooj liab -Alloy Seamless Tubes. Npog C22000 cov raj siv hauv cov kav dej, cov kav dej, thiab cov khoom siv hluav taws xob.
ASTM B152 / B152M: Txuj Specification rau Copper Sheet, Sawb, Phaj, thiab Rolled Bar. Siv rau C22000 cov khoom lag luam tiaj tus (cov ntawv txheeb, cov strips) rau kev tsim vaj tsev, kho kom zoo nkauj, thiab kev lag luam.
ASTM B280 / B280M: Txuj Specification rau Seamless Copper Dej Tube. Qhia meej C22000 cov raj rau dej haus, cua sov, thiab cua txias tshuab (ua raws li cov cai thoob ntiaj teb cov kav dej).
ASTM B32/B32M: Txuj Specification rau Solder Hlau. Xws li C22000 ua cov khoom siv rau siab -corrosion- tsis kam solder alloys.
2. International Standard (Lub Ntiaj Teb Kev Sib Haum Xeeb)
TS EN ISO 13373-1: Copper and Copper Alloys – Seamless Tubes for Heat Exchangers, Condensers, and Evaporators – Part 1: Dimensions and Tolerances. Aligns nrog ASTM cov qauv rau C22000 thermal daim ntawv thov raj.
ISO 13374 Kev Tswj Xyuas Kev Lag Luam: Copper and Copper Alloys – Seamless Tubes for Water and Gas Supply . Npog C22000 cov kav dej kav dej, ua kom muaj kev sib raug zoo thoob ntiaj teb kev lag luam.
3. Regional Standards (Key Export Markets)
Cov European Union (EN):
TS EN 1057: Copper thiab Copper Alloys - Seamless Tubes rau Kev Siv Dej thiab Roj Sib npaug rau ASTM B280 rau C22000.
TS EN 12735-1 Copper thiab Copper Alloys - Seamless Tubes rau cua txias thiab tub yees - Ntu 1: Qhov ntev thiab kam rau ua
Japanese Industrial Standard (JIS):
JIS H3300: Copper thiab Copper Alloy Tubes. C22000 sib raug rau JIS C2200 (liab tooj dag raj) rau kev siv kav dej thiab kev siv vaj tsev.
Suav Standard (GB):
GB/T 1527: Copper thiab Copper Alloy Seamless Tubes. C22000 yog sib npaug rau GB HSn62-1 (ib qho tooj liab-zinc-tin alloy) rau kev xa tawm mus rau Suav lag luam.
German txuj (DIN):
DIN 17660: Copper thiab Copper Alloys - Semi -Cov khoom tiav. C22000 ua raws li DIN CuZn20 (20% zinc ntsiab lus) rau kev lag luam thiab kev siv vaj tse.
