2006年5月,开封空分集团有限公司成功研制压力达7.41MPa的高压板式主换热器,这是该公司板式换热器生产历史上的一个突破。长期以来,内压缩流程空分设备配套的高压板式,绝大多数依靠进口,不仅价格高,生产周期也长,为成套空分的制造带来困难。今年开封空分为国丰钢厂、鄂城钢厂生 In May 2006, Kaifeng Air Separation Group Co., Ltd. successfully developed a pressure of 7.41MPa pressure plate-type main heat exchanger, which is the company plate heat exchanger production history of a breakthrough. For a long time, the internal pressure compression process air separation plant supporting high-pressure plate, the vast majority rely on imports, not only the high price, the production cycle is also long, it is difficult for the manufacture of complete sets of air separation. Kaifeng this year, the country is divided into empty steel mills, Echeng steel mill students
