Steel pipes are a common type of tubing, which can be categorized into different types such as seamless pipes and welded pipes. What is the difference between seamless pipes and welded pipes? Next, the editor will briefly introduce them to you.

What is the difference between Seamless Tube and Welded Tube?

1. Different processes

Seamless tubes are made by piercing billets or solid pipe blanks and then processed through hot rolling or cold rolling. Welded tubes are formed by bending and welding steel plates or strips.

2. Different Appearance

Seamless steel pipes have no seams on their surface. Welded pipes typically have weld seams.

3. Varying Wall Thickness

Seamless steel tubes have lower precision and relatively thicker walls. Welded steel tubes offer higher precision and are typically thinner-walled.

4. Different raw materials

Seamless steel tubes are made from billets or solid pipe blanks. Welded tubes are produced from steel plates or strips.

5. Varying Performance

In terms of corrosion resistance, pressure-bearing capacity, and high-temperature resistance, seamless steel pipes outperform welded pipes.

6. Price Variations

Seamless steel pipes are more expensive than welded pipes due to the more complex production process and higher costs involved in making seamless steel pipes.

7. Different Functions

Seamless steel pipes are generally used as transport pipelines for fluids in environments requiring high pressure and high temperature resistance. Welded pipes are typically used for low-pressure fluid transport.
