🔹 1. Welded Gas Pipe (Seamed Pipe)
These pipes are produced from steel sheets, and their longitudinal seam is closed by welding.
That’s why they are also called seamed or welded pipes.
They are usually used in lower-pressure applications (such as domestic and building gas piping).
Their price is lower compared to seamless pipes.
Weak point: The welded seam may be weaker against pressure or impact.
🔹 2. Seamless Gas Pipe
These pipes are manufactured through a special process and have no seam or welding line.
They have higher mechanical strength and are suitable for high-pressure applications.
They are mostly used in the oil, gas, and petrochemical industries, as well as in areas where safety is highly critical.
Due to their higher quality and durability, they are more expensive compared to welded pipes.
