Stainless steel welded pipe is a type of pipe made from stainless steel that has been welded together using various welding techniques. It is commonly used in industries such as oil and gas, chemical, and petrochemical, as well as in construction and infrastructure projects.

Seamless pipes are high-quality pipes made from a solid cylindrical steel billet, which is heated and formed into a pipe through a piercing process. They have no welded seams, ensuring a uniform composition throughout the entire pipe and making them ideal for high-pressure and high-temperature environments. Seamless pipes are widely used in various applications such as the oil and gas industry, chemical processing, and medical equipment due to their excellent strength and corrosion resistance. Additionally, their smooth interior surface minimizes friction, making them suitable for applications requiring the efficient flow of liquids or gases.

As the name suggests, seamless steel pipes have no seams (creases) or welded joints. Welded steel pipes are made of flat steel plates with welds on the pipe body. Welded steel pipes are always available in large quantities due to their lower production costs and availability of raw materials.
