Ob Txoj Kev, Ib Yam Khoom Specification
Titanium raj rau condensers thiab kub exchangers yog tsim los ntawm ob txoj kev sib txawv, thiab ob qho tib si raug them rau tib tus qauv. ASTM B338 siv rau seamless thiab welded titanium thiab titanium alloy raj rau condensers thiab tshav kub exchangers, thiab lub domestic sib npaug splits ob txoj kev ntawm GB / T 3624 rau seamless raj thiab GB / T 3625 rau welded raj. Seamless yeeb nkab npog los ntawm ASTM B861 thiab welded yeeb nkab los ntawm ASTM B862.
Cov lus nug tswv yim rau tus neeg yuav khoom tsis yog txoj hauv kev twg yog qhov zoo dua tab sis txoj kev twg muab cov kev xav tau ntawm kev sib txuas ntawm phab ntsa, qhov ntev, lub peev xwm siab, qhov chaw thiab tus nqi rau qhov tshwj xeeb exchanger tsim. Ob txoj kev sib txawv ntawm txhua qhov ntawm cov ntsiab lus ntawd.
Yuav Ua Li Cas Seamless Titanium Tube Ua
Seamless raj pib los ntawm ib tug khoom billet los yog hollow, uas yog pierced thiab extruded ntawm siab kub, ces txias txo mus rau qhov kawg qhov ntev los ntawm pilger dov los yog ntsaws dov, nrog intermediate annealing thiab pickling ntawm txo cov kauj ruam. Qhov kawg dhau teev qhov ntev, qhov chaw tiav thiab cov qauv kev ntxhov siab seem.
Tsis muaj qhov sib koom ua ke ntev, yog li tsis muaj vuam thiab tsis muaj cua sov- cuam tshuam thaj chaw nyob qhov twg ntawm qhov ntev.
Cov cuab yeej thiab kev coj tus cwj pwm tsis zoo yog ib puag ncig ib puag ncig tag nrho, uas yog qhov tseem ceeb ntawm qhov chaw ntawm lub raj xa mus rau hauv cov ntawv raj thiab tag nrho cov phab ntsa yog loaded.
Kev muaj peev xwm siab dua rau cov phab ntsa tuab, vim tias tsis muaj vuam seam uas nws qhov ua tau zoo teev qhov txwv.
Lub sij hawm ua cov khoom siv sij hawm ntev dua thiab cov nqi tsev siab dua, vim tias cov cuab yeej extrusion thiab txias txo cov kauj ruam yog kim thiab cov txheej txheem tsis kam rau kev txiav txim me me.
Seamless raj feem ntau yog qhov tshwj xeeb ntawm kev xaiv rau siab - kev pabcuam siab, rau lub raj uas yuav khoov lossis ua haujlwm hnyav tom qab xa khoom, thiab rau cov ntawv thov uas qhov vuam hauv phab ntsa tsis tuaj yeem lees txais rau tus neeg siv khoom kawg tus qauv engineering.
Yuav Ua Li Cas Welded Titanium Tube Ua
Welded raj yog tsim los ntawm txias- dov titanium sawb lossis coil. Lub sawb yog txiav mus rau qhov dav dav, tsim tsis tu ncua mus rau hauv ntu - lossis rau hauv cov square thiab lub voj voos hollow seem uas yuav tsum tau - thiab cov npoo ntev tau koom nrog cov pa roj tungsten arc vuam nyob rau hauv tag nrho inert- roj tiv thaiv, nrog trailing shields thiab sab hauv purge.
Tom qab ntawd lub vuam yog txias, lub raj yog qhov loj thiab ncaj, qhov saum npoo yog pickled thiab descaled kom tshem tawm cov oxide thiab cov cua sov- cuam tshuam cov xim tsis zoo, thiab lub raj ua rau lub siab tsis zoo thiab tsis yog - kuaj kev puas tsuaj. Welded raj feem ntau muab annealed thiab pickled.
Qhov zoo ntawm txoj kev welded yog phab ntsa uniformity, vim hais tias cov phab ntsa thickness yog cov strip thickness thiab zoo ib yam nyob ib ncig ntawm lub voj voog nyob rau hauv lub sawb kam rau ua; ntev nruam ntev, vim hais tias sawb yog nkag rau hauv coil; muaj peev xwm rau cov phab ntsa nyias nyias, nqes mus rau 0.2 hli thiab hauv qab ntawm me me diameters; tighter sab nraud txoj kab uas hla kam rau ua nyob rau hauv lub teeb gauges; thiab tus nqi qis dua rau ib 'meter', vim tias tsis muaj extrusion lossis txias txo yog xav tau.
Sib piv Ob Txoj Kev
| Kev ntsuas | Seamless raj | Welded raj |
|---|---|---|
| Longitudinal sib koom | Tsis muaj | Ib, inert{0}}gas welded |
| Phab ntsa uniformity | Zoo, nrog qee qhov eccentricity | Zoo heev, teem los ntawm strip thickness |
| Siab muaj peev xwm | Siab dua rau vaj huam sib luag | Txaus rau feem ntau cov cua sov-exchanger lub luag haujlwm |
| Nyias phab ntsa muaj peev xwm | Txwv los ntawm kev txo qis txias | nqes mus txog 0.2 hli thiab hauv qab |

Square thiab rectangular titanium hollow seem yog tsim los ntawm txias sib sau thiab vuam es tsis txhob seamless. Phab ntsa thickness yog cov sawb tuab, thiab lub kaum sab xis sab nraud feem ntau yog nruab nrab ntawm ob thiab peb zaug ntawm phab ntsa tuab, nrog rau lwm cov radii ua los ntawm kev kho cov txheej txheem yob.
Kev xaiv cov cai thiab cov ntaub ntawv zoo
Peb cov lus nug feem ntau daws qhov kev xaiv. Puas yog lub raj yuav nthuav dav, dov lossis khoov ntawm qhov chaw, qhov twg qhov vuam - phab ntsa dawb tshem tawm tag nrho cov kev pheej hmoo? Puas yog phab ntsa nyias dua li ntawm 0.5 hli, qhov twg welded raj yog cov lus teb? Thiab puas yog qhov ntsuas ntsuas ntawm qhov ntsuas kub ntawm qhov ze ntawm lub raj muaj peev xwm, qhov twg seamless yog txoj kev nyab xeeb dua?
Rau welded raj, lub weld yog qhov tshwj xeeb uas tswj kev lees paub, yog li txoj kev tshuaj xyuas yuav tsum hais ncaj qha: eddy tam sim no kuaj rau ASTM E426 thoob plaws qhov ntev thiab tag nrho ib ncig, kev kuaj ultrasonic ntawm seam qhov twg yuav tsum tau kuaj volumetric, flattening kev ntsuam xyuas los qhia weld ductility, thiab hydrostatic los yog pneumatic siab kuaj. Dimensional checks yuav tsum npog sab nraud txoj kab uas hla, phab ntsa thickness, ovality, ntev, ncaj thiab xaus squareness, vim hais tias tawm - ntawm - round tube yuav tsis muab khi rau hauv ib lub raj ntawv, thiab ib tug burred los yog puas weld hlaws yog ib tug tshwm sim ntawm ua tsis ua hauj lwm ntxov ua hauj lwm.
Rau ob txoj kev, daim ntawv pov thawj zeb yuav tsum tau muab rau EN 10204 3.1 nrog tus lej xov tooj cua sov, thiab tus neeg hais qhia yuav tsum hais tus qauv, qib, sab nraud txoj kab uas hla, phab ntsa thickness, ntev, tus me nyuam qhov xwm txheej, kev xeem yuav tsum tau ua thiab ua tiav ntawm theem kev txiav txim. Titanium raj yog yuav rau ib qho kev qhia tshwj xeeb, tsis yog rau cov lus piav qhia dav dav, thiab qhov sib txawv ntawm seamless thiab welded raj yuav tsum tau sau rau hauv qhov kev txiav txim vim tias ob qho tib si tsis sib hloov ntawm qhov chaw ntawm kev teeb tsa.
Cov lus nug nquag
Q: Puas yog welded titanium raj muaj zog li seamless?
A: Rau qhov sib npaug ntawm phab ntsa tuab lub raj seamless feem ntau muaj qhov ntsuas siab dua, vim tias cov vuam teeb tsa qhov kev txwv nyob rau hauv welded raj. Rau cov cua sov li qub-txoj haujlwm sib pauv hauv kev txwv tsim, welded raj ua tau zoo txaus.
Q: Txoj kev twg muab cov phab ntsa zoo dua qub?
A: Welded tube, vim hais tias cov phab ntsa yog lub strip thickness thiab yog ib yam nyob ib ncig ntawm lub voj voog nyob rau hauv lub sawb kam rau ua. Seamless raj tuaj yeem qhia ntsuas phab ntsa eccentricity los ntawm kev txo qis.
Q: Qhov twg yog pheej yig dua?
A: Welded raj, feem ntau ua tau. Nws zam extrusion thiab txias txo, siv sawb nyob rau hauv coil, thiab yog tsim nyob rau hauv cov kab nruam, yog li cov nqi tsev ib 'meter' yog qis dua tshwj xeeb tshaj yog nyob rau hauv nyias phab ntsa.
Q: welded raj puas tuaj yeem muab tau rau hauv square lossis rectangular seem?
A: Yog. Square thiab rectangular hollow seem yog tsim los ntawm sawb thiab welded, nrog rau sab nraum lub kaum sab xis vojvoog feem ntau yog ob mus rau peb zaug ntawm phab ntsa thickness thiab lwm yam radii ua rau kev txiav txim.
Q: Yuav tsum kuaj dab tsi rau welded raj?
A: Eddy kev ntsuam xyuas tam sim no rau ASTM E426 dhau qhov ntev, kev kuaj xyuas ultrasonic ntawm cov seam qhov twg teev, flattening kev ntsuam xyuas rau weld ductility, thiab hydrostatic los yog pneumatic siab kuaj, ntxiv rau qhov ntsuas qhov ntev.
Q: Tus txheej txheem twg npog ob leeg seamless thiab welded raj?
A: ASTM B338 npog seamless thiab welded titanium thiab titanium alloy raj rau condensers thiab tshav kub exchangers. GB / T 3624 npog seamless raj thiab GB / T 3625 npog welded raj, nrog ASTM B861 thiab ASTM B862 siv rau cov yeeb nkab.
