What is the purpose of cold-drawn square steel pipe?
1: Origin of cold-drawn square steel pipe
Cold-drawn square steel pipe is a new type of steel pipe product, which is produced due to the needs of industry. In the past, most of the production methods of steel pipes were hot-rolled or cold-rolled, but both of them had some defects. The hot rolling process requires high temperature and high pressure conditions, and is easy to cause oxidation on the steel pipe surface. The cold rolling process requires a long production cycle. Therefore, the industry began to look for a new steel pipe production process, and finally developed the cold-drawn square steel pipe process.
2: Principle of cold-drawn square steel pipe
The principle of cold-drawn square steel pipe is the process of drawing steel into the required shape at high temperature. Steel becomes soft at high temperature and can be well stretched and shaped. The cold-drawn square steel pipe is stretched into the required shape by rotating.
3: Advantages of cold-drawn square steel pipe
The cold-drawn square steel pipe has the advantages of uniform material, high forming accuracy, good surface finish and high strength. These advantages make cold-drawn square steel pipes widely used in many fields such as oil, natural gas, chemical industry, electricity, paper making, food, water treatment, machinery, etc.
4: Application scope of cold-drawn square steel pipe
The cold-drawn square steel pipe has a wide range of applications, which can be used in construction, chemical, machinery, food, and power industries. Cold-drawn square steel pipe is a manufacturing process, which can produce pipes of different shapes. The advantage of cold-drawn square steel pipe is that it can produce high-strength and high-temperature resistant pipes, which are usually used for high-pressure pipes or wear-resistant pipes.
