双翅鳍片管是制造大容量电站锅炉膜式水冷壁需用量很大的一种异型钢管,在国内货源供应上尚有一些困难,国外资本家就乘机屡次提高价格以转嫁能源危机;对30万瓩直流炉必需的小口径内螺纹鳍片管则是刁难封锁,拒不出售。为了自力更生发展我国电力工业,我厂供应科在各车间支持下花了一年半时间自行设计制造了成套鳍片管高频焊设备,并初步配备了拉拔成圈扁钢的附属装置,成功地用光管扁钢焊接了二台30万瓩
Finned finned tube is a kind of special-shaped steel tube with a large amount of membrane wall used for manufacturing large-capacity power station boilers. There are still some difficulties in supply of domestic sources. Foreign capitalists frequently take the opportunity to raise prices to pass the energy crisis. For 300,000瓩 DC furnace required small-caliber internally threaded finned tube is difficult to block, refused to sell. In order to self-reliance on the development of China’s power industry, I plant supply department in the workshop with the support of a year and a half to design and manufacture of complete sets of fin tube high-frequency welding equipment, and initially equipped with drawing flat steel attachment, successfully Flat tube with light pipe welded two 300,000 瓩
