Stainless steel (SS) pipes are widely used across industrial, commercial, and residential applications due to their exceptional corrosion resistance, durability, heat tolerance, and hygiene standards.
| Grade | Key Characteristics | Best Used For |
| SS 304 / 304L | Standard austenitic grade; excellent general corrosion resistance. "L" variant has lower carbon for better weldability. | Water supply, food & dairy processing, architectural handrails, light industry. |
| SS 316 / 316L | Contains 23% molybdenum for enhanced protection against chlorides and salts. | Marine environments, chemical processing, pharmaceuticals, coastal installations. |
| SS 310 / 310S | High chromium and nickel content; superior resistance to oxidation at elevated temperatures. | Furnaces, heat exchangers, high-temperature exhaust and burner parts. |
| SS 321 / 347 | Titanium (321) or Niobium (347) stabilized to prevent intergranular corrosion during heating. | Aircraft exhaust, refinery piping, high-temp chemical processing. |
| Duplex (e.g., 2205) | Mixed austenitic-ferritic structure; double the yield strength of 304/316 and high pitting resistance. | Offshore oil & gas platforms, desalination plants, heavy chemical tankers. |
Seamless Pipes: Extruded from solid round steel billets with no weld seam. Ideal for high-pressure, high-temperature, or critical environments.
Welded Pipes (ERW / EFW / SAW): Formed from flat steel sheets or coils and welded longitudinally. Cost-effective and widely used for moderate-pressure and structural systems.
Nominal Pipe Size (NPS / NB): Defines the standard nominal size (e.g., $1/2"$, $1"$, $2"$, $4"$).
Pipe Schedule (Wall Thickness): Designated by schedule numbers (e.g., SCH 5S, SCH 10S, SCH 40S, SCH 80S).
The suffix "S" denotes stainless steel dimensions under ASME/ANSI B36.19.
Higher schedule numbers indicate thicker walls, enabling higher pressure tolerance.
Key Standards:
ASTM A312 / ASME SA312: Standard specification for seamless, welded, and heavily cold worked austenitic stainless steel pipes.
ASTM A269 / A213: Tubes for general service, boilers, and heat exchangers.
ASTM A554: Stainless steel tubing for mechanical and decorative applications.
