stainless steel hydraulic pipe

Product Description

The 304 Stainless Steel Hydraulic Tubing has a good content of nickel and chromium with other constituent alloys. This allows the tubes to work well in elevated pressure as well as in stress-induced environments. A High Pressure Hydraulic Tube combines strength with excellent handling enabling the tubes to work well in high pressure applications while ensuring optimum safety in the system. These hydraulic tubes have an excellent service life and are easy to work with. Industrial Hydraulic Tubes are very reliable and can be shaped in different dimensions and shapes to meet project requirements. 


The pipes in this grade are produced in either seamless or welded configurations. A Stainless Steel Seamless Hydraulic Pipe is designed via an extrusion process as hot steel billets are passed through metal to shape them in correct dimensions. The versatile grade of pipes have excellent strength and exhibit 20% higher load-bearing capacity over an SS Welded Hydraulic Pipe. The welded pipe cannot handle extreme pressures, but can be shaped in different dimensions and are considerably cheaper than the seamless grade. The Stainless Steel Welded Hydraulic Pipe is produced as steel is rolled and welded in place with or without filler material. These pipes are durable and offer good service to customers.
