Stainless Steel Pipe Size

Stainless steel pipe is used for structural and piping applications that require the properties that stainless steel delivers – high strength, toughness and excellent corrosion resistance. The pipe is available in sizes 1/2" through 36" in outside diameter and schedules 05S through 80S and larger for wall thickness. It is available as welded and seamless. Stainless pipe has a dull gray, mill finish.

Seamless stainless pipe is used for applications that require internal pressure within the pipe such as process equipment, water treatment and marine applications. Welded pipe is used for structural applications that are exposed to corrosive environments such as marine and external applications. These include handrails, poles and support piping.

Why stainless pipe?

Corrosion Protection

Coating or cathodic protection is not required for stainless steel in most locations. A thin chromium-rich self-healing oxide film provides corrosion protection for stainless steel and no corrosion allowance is required. Erosion Resistance Stainless steels are much more resistant to erosion-corrosion caused by high flow rates and particulate matter than steel. They can handle high velocity and turbulence (pumps) without suffering wall thickness erosion.

Low Coefficient of Friction

Stainless steel retains low hydraulic friction properties as compared to aging cement lined or corroded steel pipes, which results in lower water pressure losses and pumping cost savings.

Ease of Fabrication

Stainless steels have excellent ductility and can be formed and welded into lightweight shapes, which assists in the handling and installation of pipelines. Stainless steel pipe is highly interchangeable and easily connected with other water piping systems and materials using couplings and fittings.

Long Pipe Lengths

Stainless steel pipe can be ordered in 20-foot and 40-foot lengths and even 60-foot lengths for pipe diameters up to 16-inches. Ductile iron is only available up to 20 feet in length. The number of joints, and therefore cost, is reduced for long stainless steel pipe strings.
