Seamless Stainless Steel Pipe

Stainless steel pipe is primarily used in piping systems for the transport of fluids or gases. Stainless steel pipe resists oxidation, making it a low-maintenance solution that is suitable for high temperature and chemical applications. Because it is easily cleaned and sanitized, stainless steel pipe is also desired for applications involving food, beverages and pharmaceutical applications.

The term “pipe” and “tube” are often used to describe the same product, but it is important to know the difference. Though they share the same cylindrical shape, steel pipes are measured by the interior diameter (ID), whereas steel tubes are measured by the outside diameter (OD) and wall thickness. Another difference is that pipes are used to transport fluids and gases, while tubes are used to build parts or structural components.

Tube and fittings for:

Fluid application in Sanitary, Beverage, Food, Dairy, Pharmaceutical product production and storage.

Heat applications such as heat exchangers, condenser tube

Mechanical applications such as automotive, structural, and decorative

Pipe and fittings for:

Fluid application in Petrochemical, Desalination, Mineral processing, Power generation, Oil and Gas recovery plants.

Industrial, structural and decorative applications

The above are some of the industry and applications where stainless steel tubular products are generally is use. Overall they have a use in environments where strength, corrosion, hygiene or aesthetics is a factor in design and application.
