A single piece of metal used to create a tubular structure, seamless steel tube offers the benefits of excellent sealing, high strength, and resistance to corrosion. Hence, seamless steel tubes find extensive application in various domains, including but not limited to petroleum, chemical industry, electric power, construction, and machinery manufacturing. The production procedure, equipment choices, and other relevant topics pertaining to seamless steel tubes will be covered in this article.
The production process of seamless steel tube mainly includes the following steps:
Heat treatment:Heat treatment is the process of raising the temperature of raw metal materials to a high point in order to modify their internal structure and increase their hardness and strength.
Rolling: To create a tubular structure, the heated metal raw material is plastically deformed in a rolling mill.
Straightening: To guarantee that the rolled steel pipe is round and straight, it is straightened.
Surface treatment: To increase the surface quality and corrosion resistance of steel pipes, various procedures such as cleaning, polishing, and anti-corrosion treatment are carried out.
The selection of equipment for seamless steel tube production has an important impact on its quality and output.
The following are some main equipment and their selection basis and principles:
1. Centrifugal casting: This process creates steel pipes of superior quality. The primary factors influencing the choice are the production volume, the kind and composition of the metal raw materials, the product’s diameter and length, etc.
2. Heat treatment furnace: An essential piece of equipment for the heat treatment stage is the heat treatment furnace. The primary determinants of its choice are the kind of material, rate of heating, and retention duration.
3. Rolling mill: The essential piece of machinery for the rolling stage is the rolling mill. The product’s diameter, length, material, accuracy requirements, etc. are the primary factors in its selection. Considerations for selection should include the equipment’s production capacity, dependability, and maintenance costs.
