There are two types of stainless steel tubes: welded tubes and seamless tubes. Stainless steel is used to create seamless tubes, which are often stronger and more long-lasting than welded tubes. On the other hand, welded tubes are created by joining two or more stainless steel parts through welding.
Stainless steel tubes are excellent for a variety of applications since they are offered in a wide range of diameters, shapes, and wall thicknesses. They can also be produced using different stainless steel grades, each having specific qualities, including 304, 316, and 321, among others.
