Taw qhia
Kab lus no sib piv cov txhuas thiab tooj liab raj rau cov kev pabcuam cua txias, suav nrog kev hloov cua sov thiab kev txwv siab. Lub raj tooj liab yog tsim nyob rau hauv ntau qib, tempers thiab qhov ntau thiab tsawg uas tau xaiv los ntawm cov kev pabcuam: kev faib dej, cua txias thiab tub yees, kev sib pauv cua sov, cov kab roj thiab cov roj siv kho mob. Kab lus no piav qhia seb hom raj tooj liab tau txhais li cas thiab xaiv qhov kev qhia tshwj xeeb.
Copper Tube Hom los ntawm Daim Ntawv Thov
Cov tsev neeg feem ntau yog cov raj dej, ACR raj thiab cov raj hluav taws xob dav dav. Cov raj dej yog them los ntawm ASTM B88 hauv hom K, L thiab M nrog cov phab ntsa sib txawv, ACR raj los ntawm ASTM B280 hauv kev kub ntxhov nrog cov huab cua qhuav, thiab cov raj dav dav los ntawm ASTM B75. Hauv Tebchaws Europe tus qauv sib xws yog EN 1057, thiab hauv Suav teb GB / T 18033 npog cov raj dej thiab GB / T 1527 rub raj.
Hom K, L thiab M piav qhia
Hom ntawv qhia txog phab ntsa thickness ntawm ib lub cheeb sab nraud. Hom K muaj cov phab ntsa tuab tshaj plaws thiab qhov ntsuas siab tshaj plaws, Hom L yog dav dav - lub hom phiaj cov kav dej phab ntsa, thiab Hom M yog cov phab ntsa uas pheej yig dua rau cov tshuab siab tsawg -. Tib txoj kab uas hla sab nraud yog siv rau tag nrho peb cov khoom siv sib hloov, thiab kev xaiv phab ntsa yog tsav los ntawm kev ua haujlwm siab ntawm qhov system.
| Hom | Phab ntsa | Kev siv yam | Txuj |
|---|---|---|---|
| K | Thickest | Kev kub siab, underground | ASTM B88 |
| L | Nruab nrab | General kav dej | ASTM B88 |
| M | Nyias | Tsawg-siab tshuab | ASTM B88 |
| ACR | Kos | Cov kab tub yees | ASTM B 280 Cov Lus Qhia |
Tempers thiab Forms
Tube yog nkag rau hauv kev kos tempers rau ACR kev pab cuam, uas muab lub zog los tuav cov duab thiab tiv thaiv kev co, thiab nyob rau hauv annealed coils rau cov kav dej, uas khoov tau yooj yim thiab tuaj yeem raug nab los ntawm framing. Ncaj ntev, coils thiab pancake coils muaj, thiab sab hauv grooved raj yog siv los txhim kho cov cua sov hloov hauv cov evaporators thiab condensers.
Kev koom tes thiab Standards
Copper raj yog koom nrog brazing, soldering, flaring thiab mechanical press fittings. Qib raj yuav tsum sib haum nrog txoj kev sib koom ua ke, thiab phosphorus -deoxidized qib xws li C12000 thiab C12200 yog qhov nyiam rau cov tshuab brazed vim lawv tiv thaiv cov hydrogen embrittlement.
Xaiv Daim Ntawv Teev Npe
Txiav txim siab ua hauj lwm siab thiab kub, xaiv hom thiab temper, paub meej tias qib thiab tus qauv, thiab xyuas qhov chaw thiab sab hauv huv si ua ntej installation.
