Yog vim li cas ib yam khoom ua hauj lwm sib txawv heev
Seamless tooj liab raj yog tsim los ntawm tho thiab kos ib tug cam khwb cia hlau, yog li cov khoom tiav tsis muaj longitudinal weld thiab ib tug uniform, nplua -grained qauv. Nws cov thermal conductivity ntawm kwv yees li 390 W / (m·K), nws cov ductility nyob rau hauv annealed mob thiab ruaj khov oxide patina uas tsim rau ntawm nws nto yog peb yam khoom uas piav qhia vim li cas cov khoom siv tib yam tshwm sim hauv cov kav dej, tub yees, hydraulics thiab cov khoom siv cryogenic.
Lub raj tooj liab kuj yooj yim rau kev koom ua ke. Nws tuaj yeem khoov txias rau lub vojvoog nruj, flared, swaged thiab koom nrog capillary brazing, uas txhais tau hais tias ib lub kauj ntawm lub raj tuaj yeem ntsia tau rau ntawm qhov chaw nrog ob peb fittings. Hauv kev xyaum qhov sib txawv ntawm ib daim ntawv thov thiab lwm qhov tsis yog cov hlau nws tus kheej tab sis cov phab ntsa tuab, qhov kub thiab txias uas tau txiav txim siab.
Daim Ntawv Thov Cov Tube Loj Loj
Cov chaw tsim kho thiab cov khoom siv hnyav.Excavators, cranes, qhob twj tso kua mis thiab drilling rigs cia siab rau lubrication thiab hydraulic circuits. Lub raj tooj liab raug xaiv rau cov tsav tsheb me me thiab cov kab lubrication vim nws tiv thaiv kev co qaug zog, tsis xeb hauv kev pabcuam thiab tuaj yeem rov ua dua -tsim nyob ib puag ncig cov qauv uas twb muaj lawm.
Txheej txheem factories.Condensers, intercoolers, aftercoolers thiab heat exchange batteries in chemical, food and compressed-air plants use copper tube as the heat-transfer element. Copper lub siab thermal conductivity tso cai rau lub pob compact hloov lub luag haujlwm yuav tsum tau ntawm qhov sib txawv ntawm qhov kub thiab txias.
Oxygen thiab cryogenic cog.Cov chav sib cais cua, cov pa oxygen thiab cov kab nitrogen tsawg thiab qis - cov kav dej kub siv tooj liab vim nws ua rau muaj txiaj ntsig zoo ntawm qhov kub thiab txias thiab tsis ua nkig, tsis zoo li ntau cov ntaub ntawv ferrous.
Cua txias thiab tub yees.Condensers, evaporators, capillary kab thiab interconnecting suction thiab kua kab yog tag nrho cov ua los ntawm tooj liab raj, feem ntau yog nyob rau hauv lub annealed temper kom lub raj yuav coiled thiab teb -bent nyob ib ncig ntawm lub tsev.
Instrumentation thiab tswj.Me me - txoj kab uas hla lub raj xa cov teeb liab siab rau cov ntsuas ntsuas, cov khoom xa tawm thiab cov kws tshuaj ntsuam xyuas, qhov chaw huv huv, qhov tseeb ntawm phab ntsa tuab thiab qhov ntev dua yog qhov tseem ceeb.
Kev pabcuam Marine thiab offshore.Copper alloy tube xws li C70600 tooj liab-nickel yog qhov zoo dua qhov twg dej hiav txwv lossis dej txias txias yuav nrawm nrawm rau cov pa roj carbon steel.

Phab ntsa thickness nyob rau hauv lub rooj saum toj no tsis yog kho los ntawm qib ib leeg. Lub tub yees nqus kab ua haujlwm ntawm lub siab nruab nrab xav tau ib phab ntsa nyias dua li cov kab hydraulic ntawm tib txoj kab uas hla, yog li cov lus qhia tshwj xeeb yuav tsum nco ntsoov hais tawm sab nraud txoj kab uas hla, phab ntsa thickness, temper, qib thiab cov khoom txheem ua ke.
Fabrication thiab Installation Points
Txiav nrog ib tug rotary raj cutter thiab deburr lub bore; ib square, burr -dawb kawg yog lub hauv paus ntawm lub suab capillary sib koom.
Annealed raj tuaj yeem khoov txias mus rau ib lub vojvoog ntawm peb mus rau tsib npaug ntawm txoj kab uas hla sab nraud siv lub caij nplooj ntoos hlav sab hauv lossis lub tshuab khoov. Hard temper raj yuav tsum tau khoov kub los yog hloov nrog cov khoom annealed.
tooj liab-rau- tooj liab pob qij txha feem ntau yog brazed nrog tooj liab-phosphorus muab tub lim, uas yuav tsum tsis muaj flux. tooj liab-rau- tooj dag lossis tooj liab-rau- steel pob qij txha yuav tsum muaj nyiaj- cov kabmob muab tub lim nrog flux, thiab cov dej seem yuav tsum tau ntws tawm tom qab ntawd.
Thaum lub sij hawm brazing ntawm tub yees los yog oxygen pipework lub bore yuav tsum tau purged nrog qhuav nitrogen kom tsis txhob muaj oxide nplai, uas tom qab ntawd yuav thaiv capillaries los yog paug qhov nruab nrab.
Txhawb txoj kab ntawm cov ntu ntu uas tiv thaiv sagging thiab ua kom lub raj tsis sib xws ntawm cov hlau sib txawv uas qhov sib xyaw ua ke thiab kev ua galvanic tuaj yeem tshwm sim.
Kev soj ntsuam thiab tswj cov ntsiab lus zoo
Vim tias cov raj tooj liab feem ntau muab zais rau hauv phab ntsa, qab nthab lossis tshuab thav duab, qhov zoo yuav tsum tau ua pov thawj ua ntej kev teeb tsa. Paub meej txog qib thiab npau taws los ntawm daim ntawv pov thawj cov khoom siv, txheeb xyuas cov kab sab nraud thiab phab ntsa tuab nrog micrometer ntawm ob qhov kawg thiab nruab nrab -ntev, tshuaj xyuas lub bore rau residual drawing lubricant, thiab thov ib tug eddy-tam sim no xeem daim ntawv qhia rau seamless raj qhov twg tus qauv los yog daim ntawv thov hu rau nws. Rau siab- nqa circuits, hydrostatic los yog pneumatic sim ntawm lub raj zeb thiab dua tom qab kev teeb tsa yog txoj kev lees paub los ua pov thawj xau- nruj.
FAQ
Q: Cov qib tooj liab twg yog qhov zoo tshaj plaws rau kev ua haujlwm cua txias?
Phosphorus-deoxidised tooj liab xws li TP2 yog qhov kev xaiv ib txwm muaj. Kev tswj cov phosphorus ntxiv ua rau lub raj muaj kev nyab xeeb rau braze yam tsis muaj kev pheej hmoo ntawm hydrogen embrittlement, thiab lub siab kub nyhiab tso cai rau coils tsim thiab teb -bent.
Q: Puas tuaj yeem ua rau lub siab kub nyhiab tooj liab tuaj yeem khoov rau ntawm qhov chaw?
Hard temper tube muaj lub zog siab tab sis tsis tshua muaj ductility, yog li txias khoov mus rau lub vojvoog nruj yuav tawg nws. Siv annealed raj rau khoov, los yog anneal qhov khoov cheeb tsam ua ntej sib sau.
Q: Vim li cas lub raj tooj liab siv hauv cov nroj tsuag oxygen es tsis txhob siv hlau?
Copper khaws nws cov ductility ntawm qhov kub thiab txias thiab tsis ua rau txoj kev tawg, yog li nws zoo haum rau cov pa oxygen thiab nitrogen cov kev pab cuam qhov twg cov kav dej txias txias qis dua xoom.
Q: Puas yog lub raj tooj liab puas xav tau txheej txheej sab hauv rau kev pabcuam dej?
Tsis yog. Lub raj dej uas muaj peev xwm muab tau nrog lub qhov dej huv thiab tso siab rau cov yeeb yaj kiab tiv thaiv ntuj uas tsim rau ntawm tooj liab. Cov txheej txheem tsuas yog siv rau kev txheeb xyuas sab nraud lossis qhov chaw faus lub raj.
Q: Dab tsi yog qhov txawv ntawm lub raj thiab cov yeeb nkab hauv cov ntsiab lus no?
Lub raj yog teev los ntawm sab nraud txoj kab uas hla thiab phab ntsa tuab thiab yog siv qhov tseeb qhov ntev, xws li cov khoom siv hluav taws xob thiab cov cuab yeej ntsuas. Ib cov yeeb nkab yog teev los ntawm nominal bore thiab yog siv tsuas yog rau kev xa khoom.
Q: Yuav ua li cas lub raj tooj liab yuav tsum khaws cia ua ntej kev teeb tsa?
Khaws cov coils thiab ncaj ntev nyob rau hauv lub hau, tawm hauv av thiab deb ntawm ammonia, sulfur-cov huab cua thiab cov pa acidic. Kaw qhov kawg kom cov plua plav thiab noo noo tsis nkag mus rau hauv lub qhov dej.
