A269 Bright Annealed Tube

 

A269 ci raj yog welded austenitic stainless hlau raj feem ntau siv hauv cov khoom siv dav dav. Lub A269 ci ntsa iab annealed raj undergoes txias dov thiab precision kos duab, ua tiav qhov tseeb ntawm ib ncig ntawm 0.05mm. Lub puab nto muaj ib tug roughness ntawm kwv yees li Ra0.4 micrometers thiab undergoes tshav kub kev kho mob, kaj tov annealing (annealing) nyob rau hauv ib tug txo qhov cua tiv thaiv.

Cov yam ntxwv cuam tshuam qhov ci ntsa iab ntawm Annealing ntawm Stainless Hlau Tubes

1. Txawm hais tias qhov kub ntawm annealing mus txog qib uas tau teev tseg yog qhov cuam tshuam rau qhov ci ntsa iab ntawm stainless hlau annealing. Kev kho cua sov stainless hlau feem ntau suav nrog kev daws teeb meem, nrog rau qhov kub ntawm 1040 txog 1120 degree (raws li Japanese qauv). Kev soj ntsuam los ntawm ib qho kev soj ntsuam qhov nyob rau hauv lub qhov cub annealing yuav tsum qhia lub stainless hlau raj nyob rau hauv ib tug lub xeev ntawm incandescence, tsis muaj cov tsos mob ntawm softening los yog sagging.

2. Cov cua tshuab annealing yog lwm qhov tseem ceeb. Feem ntau, cov ntshiab hydrogen yog siv los ua qhov chaw annealing, nrog rau qib purity ntawm nyiam tshaj 99.99%. Yog tias lwm qhov ntawm cov huab cua muaj cov pa roj tsis zoo, cov qib purity tuaj yeem qis dua me ntsis, tab sis nws yuav tsum tsis txhob muaj cov pa ntau dhau los yog noo noo.

3. Lub sealing ntawm lub cub tawg yog qhov tseem ceeb rau kev ua tiav cov nyhuv ci ntsa iab. Ci ntsa iab cua sov yuav tsum tau muab kaw tag nrho tawm ntawm huab cua sab nraud, tsuas yog ib qho chaw nres nkoj qhib rau kev tawm ntawm cov pa roj hydrogen. Ib txoj hauv kev tshawb xyuas cov dej xau yog siv cov dej xab npum rau ntau cov pob qij txha ntawm lub qhov cub kom pom seb puas muaj cua nkag. Cov cheeb tsam feem ntau tuaj yeem xau yog qhov chaw nkag thiab qhov hluav taws xob cov kav dej ntawm lub qhov cub annealing; cov nplhaib sealing nyob rau hauv cov cheeb tsam no tshwj xeeb yog raug rau hnav thiab yuav tsum tau kuaj xyuas thiab hloov tsis tu ncua.

4. Kev kub siab ntawm cov roj tiv thaiv: txhawm rau tiv thaiv micro-leaks, yuav tsum muaj qee qhov zoo siab ntawm cov roj tiv thaiv hauv qhov cub. Yog tias siv hydrogen los ua cov roj tiv thaiv, qhov siab ntawm qhov tsawg kawg yog 20 kBar feem ntau xav tau.

5. Moisture nyob rau hauv lub cub tawg: Ua ntej, nws yog ib qho tseem ceeb los xyuas seb lub cub tawg ntawm lub cev yog qhuav. Thaum pib txhim kho lub cub tawg, cov khoom siv hauv lub tshuab hluav taws xob yuav tsum tau qhuav kom huv si. Qhov thib ob, xyuas seb puas muaj cov dej seem ntau dhau ntawm cov hlau tsis muaj hlau tso rau hauv qhov cub. Tshwj xeeb, yog tias muaj qhov hauv cov kav dej, xyuas kom tsis txhob muaj dej nkag rau hauv lawv; txwv tsis pub, nws yuav cuam tshuam cov cua hauv qhov cub.
