1. Dab tsi yog Cov Ntawv Thov Feem Ntau ntawm C12200?
Cov cheeb tsam tseem ceeb ntawm kev thov:
Fais fab kis tau tus mob: High-voltage cables, busbars, thiab transformer windings (xa superior tam sim no - nqa peev xwm nrog tsawg zog poob).
Cov khoom siv hluav taws xob: Cov khoom sib txuas, cov khoom siv hluav taws xob, cov ntawv luam tawm Circuit Board (PCB) substrates, thiab semiconductor lead thav duab (ua kom ntseeg tau tias cov teeb liab sib kis tau zoo thiab thermal dissipation).
Kev tsim roj teeb: Busbars thiab terminals rau lithium- ion roj teeb (xws li, tsheb fais fab, lub zog cia tshuab) vim muaj cov pa oxygen tsawg (tiv thaiv oxidation sab hauv thiab txuas lub roj teeb lub neej).
Thaum tshav kub kub exchangers, radiators, thiab HVAC coils (tshwj xeeb thermal conductivity ua kom muaj cua sov hloov).
Cov tshuab cua txias rau kev lag luam tshuab, tshuab aerospace, thiab cov khoom siv kho mob (tiv thaiv corrosion hauv cov khoom ua kom txias thiab tswj cov qauv kev ntseeg siab ntawm qhov kub siab).
Cov kav dej uas siv tau, fittings, thiab li qub (tsis yog - lom, corrosion- tiv taus dej tshiab, thiab ua raws li cov qauv kev nyab xeeb khoom noj xws li NSF/ANSI 61).
High-cov kav dej purity gas (piv txwv li, hauv kev tsim cov khoom siv hluav taws xob lossis cov chaw kuaj sim) vim tsis muaj qhov tsis huv (tsis txhob kis cov txheej txheem rhiab).
Cov vov tsev, cladding, thiab cov vaj huam sib luag zoo nkauj (malleable, zoo nkauj zoo nkauj golden-xim liab, thiab tsim cov patina tiv thaiv lub sijhawm).
Kev cai hlau ua haujlwm (sculptures, handrails, thiab signage) vim zoo heev ductility rau intricate shaping.
Vuam electrodes thiab brazing alloys (kom muaj zog, corrosion-cov pob qij txha tiv taus hauv cov hlau fabrication).
Cov tshuab hluav taws xob hauv hiav txwv (tiv thaiv cov dej ntsev thaum kaw kom zoo, zoo tagnrho rau kev xaim nkoj nkoj).
2. Cov Qauv Txheej Txheem rau C12200 yog dab tsi?
1. American Standards (Koom nyob rau hauv North America & Ntiaj teb no Trade)
ASTM B111/B111M: Standard Specification rau tooj liab thiab tooj liab -Alloy Seamless Tubes. Npog C12200 cov raj siv hauv cov hlab ntsha siab, cov khoom siv hluav taws xob, thiab cov kav dej.
ASTM B152 / B152M: Txuj Specification rau Copper Sheet, Sawb, Phaj, thiab Rolled Bar. Siv rau C12200 cov khoom lag luam tiaj tus (cov ntawv txheeb, cov hlua khi) rau kev siv hluav taws xob, thermal, thiab kev siv vaj tse.
ASTM B280 / B280M: Txuj Specification rau Seamless Copper Dej Tube. Qhia meej C12200 raj rau cov dej haus, cua sov, thiab cua txias tshuab (ua raws li cov kav dej thoob ntiaj teb).
ASTM B32/B32M: Txuj Specification rau Solder Hlau. Xws li C12200 ua cov khoom siv rau siab -purity 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 C12200 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 C12200 cov kav dej kav dej, kom ntseeg tau tias muaj kev sib raug zoo nrog European thiab Esxias kev lag luam.
3. Regional Standards (Key Export Markets)
Cov European Union (EN):
TS EN 12735-1 Copper thiab Copper Alloys - Seamless Tubes rau cua txias thiab tub yees - Ntu 1: Qhov ntev thiab kam rau ua
TS EN 1057: Copper thiab Copper Alloys - Seamless Tubes rau Kev Siv Dej thiab Roj Sib npaug rau ASTM B280 rau C12200.
Japanese Industrial Standard (JIS):
JIS H3300: Copper thiab Copper Alloy Tubes. C12200 sib raug rau JIS C1220 (oxygen-dawb tooj liab raj) rau kev siv hluav taws xob thiab kav dej.
Suav Standard (GB):
GB/T 1527: Copper thiab Copper Alloy Seamless Tubes. C12200 yog sib npaug rau GB T2 (oxygen-dawb tooj liab) rau kev xa tawm mus rau Suav lag luam.
