Product Description
Here is a quick technical overview of stainless steel round pipes, broken down by grades, manufacturing types, and wall thickness standards.
Key Material Grades
| Grade | Composition Highlights | Key Characteristics | Common Applications |
| SS 201 | High Mn, lower Ni (~1%) | Low cost, moderate strength, lower corrosion resistance | Indoor furniture, handrails, decorative trim |
| SS 304 | 18% Cr, 8% Ni | Standard austenitic grade, excellent formability & general corrosion resistance | Food processing, chemical piping, water supply |
| SS 316 | 16% Cr, 10% Ni, 2-3% Mo | Added molybdenum prevents pitting corrosion from chlorides & acids | Marine fittings, pharmaceutical, offshore plants |
| SS 310 | 25% Cr, 20% Ni | High heat resistance (up to 1150C), resists oxidation | Heat exchangers, furnace parts, boiler tubes |
Manufacturing Types
-
Seamless (SMLS): Extruded from a solid steel billet without any weld seams. Handles significantly higher internal pressure rating, ideal for boilers, high-pressure hydraulics, and critical oil & gas applications.
-
Welded (ERW / EFW): Formed from rolled stainless steel strip/plate and longitudinal seam welded. More cost-effective, tighter wall thickness tolerances, and suitable for structural, architectural, and moderate-pressure fluid transport.
Standard Dimensions & Wall Thickness
Pipes are specified using Nominal Pipe Size (NPS) and Schedule (Sch) per ASME B36.19M:
Wall Thickness Schedules:
-
Sch 5S / 10S: Light wall used primarily for sanitary tubing, HVAC, and low-pressure drainage.
-
Sch 40S: Standard wall general industrial fluid piping and structural applications.
-
Sch 80S: Extra heavy wall high-pressure environments, high vibration, or corrosive allowance.
Premium Material & SpecificationsCrafted from high-quality stainless steel grades 304, 304L, 316, and 316L, our round pipes feature a density of 7.98 g/cm3, ensuring durability and resistance under demanding environments. With a hardness of HRB 90, they maintain structure under pressure and temperature extremes ranging from -196C to 600C.
Versatile Manufacturing & FinishingChoose from cold drawn or hot rolled manufacturing processes to suit distinct application needs. End finishes including plain, beveled, and threaded options are available, as well as connections-welded, seamless, flanged, or screwed-adhering to various industrial standards and requirements.
Applications Across IndustriesThese pipes serve a wide range of sectors such as construction, water supply, food processing, oil & gas, and chemical industries. Their excellent corrosion resistance, polished finish, and ability to withstand up to 150 bar pressure make them reliable for transporting fluids or gases safely and efficiently.
FAQ's of Stainless Steel Round Pipe:
