Stainless Steel Seamless Pipes / Tubes

Stainless Steel seamless pipes are ideal for all structural applications where greater strength and superior corrosion resistance is required.

The properties of stainless steel are corrosion resistance, high ductility, attractive appearance and low maintenance.

Stainless steel contains chromium which provides the properties of corrosion resistance at high temperatures. Stainless steel can withstand corrosive or chemical environments due to its smooth surface. Stainless steel products are safe for long-term use with excellent resistance of corrosion fatigue.

Stainless Steel seamless pipes are ideal for all structural applications where greater strength and superior corrosion resistance is required. Having a durable mill finish and an interior welded seam, Stainless Pipe is widely used for all types of fabrication projects that are exposed to the elements – chemical, acidic, fresh water, and salt water environments. Some sizes are available with a 180 grit brushed polish.

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…
