Technical Requirements rau Capillary Titanium Tubes
Apr 09, 2024
Capillary titanium raj yog me me - txoj kab uas hla, nyias- phab ntsa titanium raj siv nyob rau hauv cov khoom sib pauv cua sov, condensers, evaporators, thiab cov twj paj nruag, thiab raws li tus qauv tubing nyob rau hauv qhov chaw ntawm kev lag luam nuclear. Lawv lub teeb yuag, lub zog siab, thiab kev tiv thaiv corrosion tsuas yog siv tau yog tias lub raj ua tau raws li qhov xav tau ntawm cov tshuaj nruj thiab qhov ntev, vim tias cov xau los yog cov phab ntsa variations nyob rau hauv ib tug capillary bundle cuam tshuam tag nrho cov exchanger. Kab lus no piav qhia txog cov txheej txheem kev cai uas tswj hwm cov kev qhia tshwj xeeb thiab kev lees paub ntawm capillary titanium raj.
Chemical Composition Requirements
Cov tshuaj muaj pes tsawg leeg ntawm titanium tubing yuav tsum ua raws li GB / T 3620.1, uas txhais tau tias muaj pes tsawg leeg txwv rau titanium thiab titanium alloy qib. Qhov twg tus neeg yuav khoom ua rov qab- tshuaj xyuas, qhov kev tso cai sib txawv ntawm cov khoom sib txawv yuav tsum ua raws li GB/T 3620.2. Rau cov haujlwm thoob ntiaj teb, cov kev cai sib npaug yog tsim los ntawm ASTM B338, ASTM B861, lossis EN cov qauv, thiab cov txheej txheem tswj hwm yuav tsum tau teev nyob rau hauv daim ntawv xaj yuav khoom. Rau kev lag luam ntshiab capillary raj, cov tswj cov ntsiab lus yog oxygen, uas teev lub zog thiab ductility, thiab hydrogen, uas yuav tsum tau khaws cia tsawg kom tsis txhob hydride embrittlement.
Dimensional Tolerances
Sab nraud txoj kab uas hla
Qhov kev tso cai sib txawv ntawm sab nraud txoj kab uas hla yuav tsum ua raws li cov lus pom zoo ntawm kev tswj hwm tus qauv, feem ntau ntxiv rau - lossis - rho tawm ib feem me me ntawm ib millimeter rau qhov ntau thiab tsawg capillary. Rau nyias- phab ntsa raj, ovality yog tswj los ntawm qhov sib piv ntawm phab ntsa thickness rau txoj kab uas hla, thiab straightness yog teev nyias, feem ntau 1 hli ib 'meter' los yog zoo dua rau ntsuas - qib raj.
Phab ntsa Thickness
Qhov tso cai sib txawv ntawm phab ntsa thickness yuav tsum tsis txhob ntau tshaj los yog rho tawm 12.5% ntawm nominal phab ntsa thickness rau seamless raj. Qhov kev kam rau siab no tsis siv rau ntawm qhov vuam seam ntawm welded raj, qhov twg cov phab ntsa raug soj ntsuam los ntawm flattening, flaring, thiab tsis yog -kev ntsuam xyuas kev puas tsuaj es tsis txhob yooj yim caliper ntsuas.
Ntev
Tube ntev yuav tsum ua raws li qhov kev xa khoom ntev. Rau kev txiav-ntev (taw-length) muab khoom, qhov sib txawv ntawm qhov tso cai yog feem ntau ntxiv rau 10 hli; rau ntau yam -length mov, ib qho nyiaj pub rau txiav poob txog li 5 hli ib ntus yuav tsum suav nrog hauv kev suav. Random ntev thiab coil mov ua raws li qhov pom zoo nyob rau hauv qhov kev txiav txim.
Tus Neeg Sawv Cev Capillary Loj thiab Cov Sijhawm
Capillary titanium raj feem ntau nkag rau sab nraud diameters los ntawm 3 hli mus rau 25 hli nrog phab ntsa thicknesses ntawm 0.3 hli mus rau 2 hli. Rau cov cuab yeej loj thiab cov kab sib hloov, cov txheej txheem cov kav dej siv tau, piv txwv li 1/8 nti (10.29 mm OD) nrog 0.89 mm phab ntsa hauv Teem caij 5, thiab 1/4 nti (13.72 mm OD) nrog 1.24 mm phab ntsa hauv Teem caij 10S. Cov neeg yuav khoom yuav tsum tau qhia lub sijhawm lossis qhov tseeb OD thiab phab ntsa, vim tias lub sijhawm teem sijhawm - tsuas yog xaj tawm phab ntsa tuab qhib hauv lub sijhawm txhais.
| NPS | OD (mm) | Phab ntsa, SCH 5 (mm) | Phab ntsa, SCH 10S (mm) |
|---|---|---|---|
| 1/8 | 10.29 | 0.89 | 1.24 |
| 1/4 | 13.72 | 1.24 | 1.65 |
| 3/8 | 17.15 | 1.24 | 1.65 |
| 1/2 | 21.34 | 1.65 | 2.11 |
| 3/4 | 26.67 | 1.65 | 2.11 |
| 1 | 33.40 | 1.65 | 2.77 |
Kev tshuaj xyuas thiab txais
Capillary tube yuav tsum tau muab nrog rau daim ntawv pov thawj zeb xeem muab tus lej ntsuas kub, tshuaj ntsuam xyuas tshuaj, thiab cov txiaj ntsig tensile, raws li EN 10204 Hom 3.1 lossis tus qauv pom zoo. Tsis yog- kev tshuaj xyuas kev puas tsuaj, suav nrog eddy tam sim no lossis kuaj ultrasonic rau qhov ntau thiab tsawg capillary thiab kuaj hydrostatic lossis pneumatic rau kev pabcuam siab, yuav tsum ua raws li tus qauv tswj hwm. Qhov teeb meem ntawm qhov chaw: lub bore sab hauv yuav tsum tau huv si, tsis muaj kab nrib pleb, laps, thiab embedded oxide, thiab pickled los yog annealed raws li tau teev tseg, vim hais tias ib tug tsis zoo bore yog ib txoj kev xau uas tsis tuaj yeem kuaj xyuas tom qab kev teeb tsa.
Daim ntawv thov
Rau cov khoom siv hluav taws xob sib txuas, paub meej tias lub raj - mus rau -tubesheet sib koom ua ke tsim thiab kev huv huv ua ntej xaj
Rau cov kab ntsuas hluav taws xob, qhia cov qib, kev ntsuas kub, thiab ntxiv NDT pom zoo nrog tus neeg yuav khoom
Rau coiled capillary mov, xyuas qhov tsawg kawg nkaus khoov vojvoog thiab qhov tsis muaj kinks nyob rau hauv tus me nyuam tus mob
Rau welded raj, xyuas kom meej tias cov vuam seam ua tau raws li qhov kev sib tw flattening thiab flaring ntawm tus qauv.
