1. Khoom siv
C11000 electrolytic tawv-pitch tooj liab: Cu Ntau dua lossis sib npaug 99.90% (Ag suav ua Cu), oxygen 0.02-0.05% (tawv- suab), conductivity txog 100% IACS, thermal conductivity ~ 391 W/m·K. Lub workhorse tooj liab rau HVAC vim tus nqi, conductivity thiab formability. Nco tseg: ETP muaj cov pa oxygen - rau brazing hauv hydrogen{11}}cov huab cua nplua nuj (los yog qhov chaw muaj kev txhawj xeeb) siv cov qib tsis muaj oxygen C10200/C10800.
2. Temper thiab daim ntawv
Annealed (O61): mos, rau khoov, flaring thiab installation - tus qauv rau teb tubing;
H02 (ib nrab-nyuaj) thiab H58: rau cov qauv ncaj nraim khiav thiab headers;
Cov ntaub ntawv: ncaj lengths, pancake coils, txheej -paj coils (LWC) rau tshuab noj.
3. ASTM B280 Requirements (A/C & Refrigeration Field Service)
Kev huv huv: sab hauv bore tsis muaj nplai, roj thiab dej noo - txheeb xyuas los ntawm kev kuaj kev huv (kev txwv qhov seem ib tus qauv);
Lub cev qhuav dej thiab capped / plugged xaus rau kaw coils;
Eddy-kev sim tam sim no ntawm txhua lub kauj; kev ntsuas siab ib tus qauv;
Qhov ntau thiab tsawg: 1/4 "mus rau 4-1/8" OD (6.35-105 mm), phab ntsa 0.5-2.5 hli, coil ntev txog 50-100 m.
4. Kev koom tes
Brazing nrog tooj liab-phosphorus muab tub lim (BCuP-2/5, xws li sil-fos hom) - tus kheej-fluxing ntawm tooj liab- mus rau- tooj liab pob qij txha; siv flux rau tooj liab- mus rau tooj dag pob qij txha. Tsis txhob overheating (brazing ntau 650-810 degree); ntxuav nrog nitrogen thaum lub sij hawm brazing ntawm huv tshuab los tiv thaiv oxidation sab hauv.
5. Cov ntawv thov
Cov chaw nyob thiab kev lag luam A/C kab teeb, tub yees circuits, condensers thiab evaporator coils, cua sov-pump tubing, thiab dav HVAC piping - qhov twg ETP tooj liab conductivity, formability thiab nqi yog cov txiav txim.
6. Kev txiav txim
Qhia meej: tus qauv (B280/B75 lossis EN 12735), qib C11000, temper, loj, daim ntawv (coil / ncaj), chav huv huv, thiab EN 10204 3.1 daim ntawv pov thawj nrog cov ntaub ntawv conductivity.
vim li cas xaiv peb
vim li cas thiaj xaiv peb cov khoom
Peb yog cov chaw tsim khoom lag luam thiab xa tawm tshwj xeeb hauv kev ua tiav ntau yam ntawm - cov khoom siv tooj liab zoo, suav nrog cov raj tooj liab, tooj liab daim hlau / ntawv, tooj liab tuav, tooj liab rods, tooj liab xov hlau, thiab tooj liab strips. Peb cov chaw tsim khoom siab heev tau nruab nrog lub xeev - ntawm - - cov kab kos duab txuas ntxiv, extrusion presses, txias dov mills, thiab cov tshuab kos duab kom paub meej thiab sib xws. Kev tswj xyuas kom zoo yog ib qho tseem ceeb rau peb cov txheej txheem, ua los ntawm spectrometers rau cov ntaub ntawv pov thawj, tensile testers, eddy tam sim no testers, thiab hydrostatic siab testers, lav tias tag nrho peb cov khoom ua tau raws li cov qauv thoob ntiaj teb rau kev ua tau zoo thiab kav ntev.
