管殼式換熱器的主要技術參數

1、低溫管殼式換熱器的主要技術參數作者：Qijian 73更新時間：2009-11-23 16:49:04低溫管殼式換熱器的主要技術參數，傳熱面積為60 m2。換熱器殼體規(guī)格為 DN 600mm材質為16MnDR;管子規(guī)格為 19X 2. 5,材質為16Mn（正火）；管板材質為16MnDI。文獻1附錄A中對主要受壓元件的要 求為：殼體、封頭、管板等鋼板及換熱管、接管用管材在正火狀態(tài)下使用，并宜采用冷成形或回火溫度以下的溫成形，須避開鋼材的回火脆性區(qū)。若在回火溫度以上熱成形時，應根據需要進行與母材相同或相類同的熱處理。管殼式換熱器是目前應 用較廣泛的一種換熱器。文獻1附錄A規(guī)定，設計溫度低于或等于-

2、20C鋼制管殼式換熱器為低溫管殼式換 熱器。管板與管子、管板與殼體的連接是管殼式換熱器質量控制的關鍵。如果連接處發(fā)生泄漏，將導致兩種工作介質混合，輕者損失熱量與產品，重者將危及設備與人身安全。本文以唐山化工機械有限公司設計制造 的固定管板低溫管殼式換熱器為例，探討受壓元件連接方式及焊接工藝。固定管板式換熱器技術參數1口我要打印口 IE收藏曲放入公文包庭我要留言 妙查看留言來源：中國換熱器網添加人：guoli添加時間：2006-7-13 13:17:18一、主要技術特性參數公稱直徑150 250400 500600 800 1000 1200設計壓力MPa0.6 1.0 1.6 2.5 4.0設
