Yuav Ua Li Cas Xaiv Txoj Cai Kub Kub Exchanger Tube?
Tso lus
Hauv kev tsim cov chaw tsim khoom, xaiv cov khoom siv hluav taws xob uas tsim nyog yog ib qho kev txiav txim siab tseem ceeb tshaj plaws. Txawm tias qhov yuam kev me me hauv kev xaiv tuaj yeem ua rau muaj kev puas tsuaj loj heev, uas ua rau lub sijhawm poob qis thiab ua rau ntau lab daus las hauv kev tsim khoom poob.
Ntawm GNEE, kos raws li peb cov kev paub dhau los ntau xyoo dhau los hauv kev xa tawm ntawm cov hlau tsis muaj steel hlau kub exchanger raj, peb tau tsim plaub yam tseem ceeb rau kev xaiv tube: qib khoom, txheej txheem tsim khoom, qhov ntev precision, thiab cov qauv tshuaj xyuas.
1. Kauj Ruam 1: Sib piv cov khoom qib rau ib puag ncig
Thawj kauj ruam yog txheeb xyuas qhov corrosive xwm thiab kub ntawm koj cov kua. Xaiv 316L thaum 304L txaus siv nyiaj pov tseg; xaiv 304L thaum Duplex yuav tsum ua rau ua tsis tiav ntxov.

2. Kauj Ruam 2: A213 Seamless Vs. A249 Welded
Xaiv Seamless (ASTM A213):Yog tias koj qhov kev khiav hauj lwm siab tshaj100 Barlos yog koj tab tom cuam tshuam nrog qhov tseem ceeb superheated chav. Seamless raj muaj 100% kev ntseeg siab uas tsis muaj cov ntsiab lus tsis muaj zog.
Xaiv Welded (ASTM A249):Rau cov qauv condensers thiab qis - mus rau - nruab nrab siab exchangers. Welded raj muajzoo dua phab ntsa thickness uniformity, uas ua kom ntseeg tau tias muaj cua sov hloov mus thoob plaws tag nrho lub raj ntim.

3. Kauj Ruam 3: Txhim kho qhov ntev rau kev hloov cua sov
Dimensions tsis yog hais txog haum; lawv dictate covKub Hloov Coefficient.
| Parameter | Standard Range | Daim ntawv yuav khoom |
| Sab nraud Diameter (OD) | 6.35mm-114.3 hli | OD me me ua rau thaj tsam ntawm qhov chaw tab sis nce siab poob. |
| Phab ntsa Thickness (WT) | 0.5-12.7 hli | Thinner phab ntsa txhim kho cov cua sov hloov tab sis txo lub neej corrosion. |
| Tube Length | 6m – 24m | Cov hlab ntsha ntev txo cov pob qij txha tab sis xav tau kev thauj khoom tshwj xeeb. |
| Daim ntawv | Ncaj los yog U-Bent | U-bent hlab tso cai rau thermal expansion yam tsis muaj kev ntxhov siab. |
4. Kauj Ruam 4: Kev soj ntsuam zoo
Tus kws tshaj lij yuav tsum muab cov ntaub ntawv, tsis yog cov lus cog tseg xwb. Xyuas kom koj PO (Purchase Order) yuav tsum muaj cov hauv qab no:
Kev txheeb xyuas cov khoom zoo (PMI): Kom paub meej tias cov alloy yog raws nraim qhov koj them rau (xws li Mo> 2.0% rau 316L).
Eddy Current Testing (ECT): Yuav tsum tau kuaj xyuas sub- deg tsis xws luag nyob rau hauv lub raj phab ntsa.
Kev Ntsuas Hydrostatic: Feem ntau 1.5x lub siab tsim los xyuas kom zero-kev ua tau zoo.
Mill Test Certificate (MTC): Yuav tsum ua raws li EN 10204 3.1 kom paub meej tag nrho.
5. Daim ntawv txheeb xyuas khoom
Ua ntej muab qhov kev txiav txim, thov nug tus neeg muag khoom peb cov lus nug nram qab no:
"Puas yog cov tubing feature 'nruab nrab phab ntsa thickness' los yog 'yam tsawg phab ntsa thickness'?" (Qhov tsawg kawg ntawm phab ntsa thickness muab kev nyab xeeb dua).
"Puas yog sab hauv qhov roughness (Ra) tswj?" (Lub smoother nto txo qhov scaling thiab fouling).
"Txoj kev ntim khoom rau kev thauj mus los ntev - yog dab tsi?" (316/310S tubing yuav tsum tau ntim rau hauv cov ntoo crates ntxiv).
