在国家工业化电气化的日益增长中,锅炉制造将随电站的需要而蓬勃发展。管子弯曲在锅炉制造中估极重要地位,一台锅炉就有上千根的弯曲管子,因此对管子的弯曲制造,就显得尤为重要。它对造船、石油、化学工业的发展,亦同样密切相关,电站的水力系统或蒸汽、石油的管路系统等都广泛地采用弯管来达到和满足发生蒸汽和输送的要求。弯曲管子的方法,目前采用者仅有两种:(1)加热弯曲:当弯曲半径小于或等于管子直径的1.5倍,或因管子数量较少时,如采用冷弯专用工艺装备的成本高,则采用加热弯曲。
In the country’s growing electrification of industrialization, boiler manufacturing will be booming with the needs of power plants. Pipe bending is very important in the manufacture of the boiler. There are thousands of bent pipes in a boiler, so it is especially important for the bending of pipes. It is also closely related to the development of the shipbuilding, petroleum and chemical industries. The hydraulic system or steam station of the power station and the piping system of petroleum are all widely used to meet and meet the requirements of steam and transportation. At present, there are only two kinds of methods for bending pipes: (1) heating and bending: when the bending radius is less than or equal to 1.5 times of the pipe diameter or because of the small number of pipes, if the cost of adopting the special cold rolling process equipment is high, Then use the heating curve.
