The manufacture of precision steel pipes requires the billet to be fed into the furnace for heating, at a temperature of about 1,200 Baidu. Hydrogen is mainly used as fuel. During the heating process, the control of the furnace temperature is the most important part. The temperature needs to be controlled within a rated range to ensure that the manufactured precision steel pipes can have more stable physical properties. After the heating is completed, it needs to be cooled by spraying water, because the steel pipe will be straightened after cooling, so that the basic prototype of the precision steel pipe can be seen, and the entire manufacturing process is still relatively complicated.
At present, the main production of precision steel pipes in my country is mainly concentrated in Chengdu, Hebei, Shandong and Jiangsu. They are widely used in fields such as pneumatic components, automobiles, petrochemicals, electric power and ships.
