Analysis of the advantages and disadvantages of hot-rolled seamless tube

Hot-rolled seamless tube/tubing is an important metal material with many advantages, but it also has disadvantages. This article will analyze its advantages, disadvantages and application fields from several perspectives.

Advantage analysis:

1. Coating
The coating of hot-rolled seamless tube has high adhesion, strong corrosion resistance, is not easily damaged, and can protect the metal surface from oxidation and corrosion.

2. Intensity
Because of the special properties of the manufacturing process, hot-rolled seamless steel pipes have relatively high strength. Applications in certain areas have significant advantages.

3. Cost

Compared with other types of pipes, the cost of hot-rolled seamless tubes is relatively low because it can reduce many manual operations in the manufacturing process, resulting in higher production efficiency and therefore cheaper prices.

Disadvantage analysis:

1. Surface finish
Compared with cold-drawn seamless steel tubes and cold-drawn welded steel pipes, the surface finish of hot-rolled seamless steel pipes is not high, with small indentations and oxidation.

2. Size deviation
During the production process, the dimensional deviation of hot-rolled seamless tubes may be larger, so it is not suitable for those fields that require high dimensional accuracy.

Application areas of hot-rolled seamless tubes and how to choose:
Hot-rolled seamless tubes are widely used in oil and gas transportation, industrial equipment, building decoration and other fields. When choosing steel pipes, you should choose according to its use environment and characteristics: in areas where higher strength is required, hot-rolled seamless tubes are a good choice. If a higher surface finish is required, you can choose cold-drawn seamless tubes or cold-drawn welded pipes.

Conclusion:

Through the analysis of the advantages and disadvantages of hot-rolled seamless tubes and the discussion of application fields, we can see that the steel pipe is not perfect, but it has significant advantages in certain fields. It is very important to choose the appropriate type of steel pipe.
