Stainless Steel Pipe Specifications

We stock stainless steel pipe in numerous grades, sizes, and wall thicknesses to meet the exact demands of your application, all available in custom-cut lengths and ready to quote.

Stainless Steel Pipe for Demanding Industrial Applications

Grade selection is the foundation of a successful stainless steel piping system. For general industrial fabrication and food-contact applications, 304 and 304L stainless pipe offer an effective combination of corrosion resistance and weldability at a competitive price. 

When your application involves chlorides, saltwater exposure, or chemical processing environments, 316 and 316L stainless pipe provide the elevated molybdenum content needed to resist pitting and crevice corrosion that would compromise a lesser material. For extreme heat, oxidizing conditions, or specialized process chemistry, we stock higher-alloy grades that maintain structural integrity where standard grades fall short.

Matching Wall Schedule to Pressure and Service Requirements

Wall thickness is equally critical to system performance. Lighter schedules, such as 5 and 10S, are common in low-pressure instrumentation and sanitary systems, while Schedule 40 and 80 stainless pipe handle the pressure demands typical in chemical processing and industrial fluid transport. For high-pressure or high-temperature service, heavier schedules up to XXH give engineers the safety margin their specifications require. We cut to your exact lengths, so you receive material ready to move directly into fabrication, with no excess stock or field trimming.

Certified Stainless Steel Piping with Complete Assembly Support

Our stainless steel pipes conform to ASTM A-312, A-358, and ASME SA-312, giving procurement teams and project engineers the documentation they need for compliance-driven projects. We also carry stainless steel pipe fittings and flanges in matching grades, making it straightforward to source complete piping assemblies from a single supplier. We finish our polished stainless steel pipe in-house for applications where surface quality affects hygiene, looks, or flow characteristics.

Frequently Asked Questions

What is the difference between stainless steel pipe and stainless steel tubing?

Pipe and tubing are both hollow stainless products, but they are specified differently. Pipe sizing is based on nominal pipe size (NPS), a standardized system in which the stated size approximates but does not equal the actual outer diameter. Tubing is specified by its actual outer diameter and wall thickness. Pipe is typically used in fluid and gas transport systems governed by pressure codes such as ASME B31.3, while tubing is more common in instrumentation, heat exchangers, and structural applications. The distinction matters for fitting compatibility, code compliance, and procurement accuracy.

Does stainless steel pipe require special handling or storage to prevent contamination?

 

Yes. Stainless steel pipe can develop surface contamination, commonly known as "rouge" or free iron contamination, if it comes into contact with carbon steel equipment, tools, or storage surfaces. This iron transfer can initiate rust on the stainless surface, which is particularly problematic for food, pharmaceutical, and high-purity applications. Best practice is to store stainless pipe separately from carbon steel, use dedicated stainless-compatible lifting and handling equipment, and cap pipe ends during storage to prevent moisture and debris ingress.

Can stainless steel pipe be used in cryogenic applications?

 

Certain grades of stainless pipe perform well in cryogenic service, which is generally defined as temperatures below -150°F (-101°C). Austenitic grades such as 304, 316, and 347 retain their toughness and ductility at very low temperatures, unlike carbon steels that become brittle. This makes them a common choice for liquid nitrogen, liquid oxygen, and LNG systems. Specific design requirements, including impact testing per ASME standards, may apply depending on the temperature range and pressure involved, so confirming grade suitability with your engineer before specifying is important.
