7 Differences between seamless pipe and seam(welded) pipe

1.Manufacturing process: Seamless pipes are made by piercing a solid billet to form a hollow tube without any welding or joining process. Welded pipes, on the other hand, are made by rolling a strip or plate of steel through a series of rollers to form a cylindrical shape, which is then welded along the seam using various welding techniques.

2.Strength and reliability: Seamless pipes are considered stronger and more reliable than welded pipes due to their uniform structure and absence of welds or joints that could weaken the pipe's integrity.
3.Cost: Seamless pipes are generally more expensive than welded pipes due to the higher production cost involved in their manufacturing process.
4.Availability: Welded pipes are widely available in different sizes and lengths, while seamless pipes are limited in availability due to the more complex manufacturing process.
5.Applications: Seamless pipes are preferred for high-pressure and high-temperature applications, while welded pipes are suitable for low-pressure and low-temperature applications.
6.Appearance: Seamless pipes have a smooth, consistent appearance due to the absence of welds or joints, while welded pipes have a visible seam or weld.

7.Maintenance: Seamless pipes require less maintenance than welded pipes since they are less susceptible to corrosion and leaks at the joints. However, both types of pipes require periodic inspection and maintenance to ensure their structural integrity and safety.
