    Production of T22 Spiral Coil Tube for Steam Generator of HTGR

    • 摘要: 優(yōu)化了高溫氣冷堆蒸發(fā)器用T22螺旋盤管的制造工藝。先通過二次冷軋+一次冷拔變形，正火+回火熱處理工藝，制造出換熱管成品直管，再采用專用多頭螺旋盤管成型機(jī)及空間彎管機(jī)對(duì)T22直管進(jìn)行盤管及彎制，經(jīng)外表面噴丸、真空消應(yīng)力熱處理、表面氧化處理、表面浸油處理等一系列工序精整加工，制造出的高溫氣冷堆蒸發(fā)器用盤管，經(jīng)檢驗(yàn)各項(xiàng)產(chǎn)品性能指標(biāo)能夠滿足相關(guān)標(biāo)準(zhǔn)及用戶要求。

       

      Abstract: The manufacturing process of the T22 spiral coil for the steam generator of the high temperature gas cooled reactor(HTGR)is optimized with the methods described as below.First the finished straight tube for making the heat exchanger tube is manufactured with the process of secondary cold-rolling+primary cold-drawing deformation and the heat treatment process of normalization+tempering, and then the said straight tube is coiled and bent by the multi-head spiral coil forming machine and the space pipe-bending machine, and afterwards subjected to a number of finishing processes namely, outer surface shot blast, vacuum stress-relief heat treatment, surface oxidation treatment and surface immersion treatment, etc.The coil tube for the steam generator of the HTGR made with the methods as above mentioned is verified via relevant inspections and tests, and shows that it has its all property indexes up to applicable specifications and the customer requirements.
