Stainless steel tube is typically measured by its outer diameter and can be used in a variety of applications including a number of structural applications.
Stainless Steel Tube is a hollow steel bar, a large number of pipes used for conveying fluids, such as oil, gas, water, gas, steam, heat exchanger, mechinical machine. In addition, engaging in bending, torsional strength of the same, lighter, and they are also widely used in the manufacture of mechanical parts and engineering structures. Also used in producing all kinds of conventional weapons, the barrel, artillery shells and so on. Range of Application
Considering the importance of outside and inside surface of stainless steel tubes for fluid power industry, Our mills are providing tubes that are free from scale, rust, seams, laps.

the main requirement for stainless steels is that they should be corrosion resistant for a specified application or environment. The selection of a particular “type” and “grade” of stainless steel must initially meet the corrosion resistance requirements. Additional mechanical or physical properties may also need to be considered to achieve the overall service performance requirements.
