11. Weight Calculation


Formula:

Weight (kg)=Side (mm)2×Length (m)×7.931000\text{Weight (kg)} = \frac{\text{Side (mm)}^2 \times \text{Length (m)} \times 7.93}{1000}

Example: 20 × 20 mm square bar, 6 m long

20×20×6×7.93÷1000=19.03 kg20 \times 20 \times 6 \times 7.93 \div 1000 = 19.03\ \text{kg}

Approximate weight = 19.03 kg


12. Tolerances


Typical dimensional tolerances depend on the manufacturing process and applicable standard (such as ASTM A276 or EN 10058). Cold-drawn and bright bars generally have tighter tolerances than hot-rolled bars.

SS ROUND PIPE

Stainless steel (SS) round pipes are cylindrical, hollow structural components heavily utilized across engineering, architecture, and manufacturing for fluid transport and structural frameworks.

Essential Material Grades
  • SS 304 / 304L: The most prominent commercial grade. Offers high general corrosion resistance and simple formability for architecture or food processing.
  • SS 316 / 316L: Superior grade containing molybdenum. Resists chloride pitting, making it ideal for marine settings and chemical processing plants. 
  • SS 202: A cost-effective, low-nickel variant. Generally used for indoor furniture, handrails, and non-corrosive decorative applications.
Key Classifications & Technical Parameters
  • Production Type: Available as Seamless (extruded without a weld line, suitable for high pressure) or Welded / ERW (rolled from steel strips and longitudinally welded).
  • Size Metric Options: Specified via Outer Diameter (OD) from 5.8 mm to 508 mm, or Nominal Bore (NB) sizes spanning 1/8 inch up to 32 inches.
  • Wall Thickness: Ranges globally from thin gauge (0.3 mm) up to heavy-walled options (50 mm). Thickness classes adhere strictly to standard Schedules such as Sch 10S, Sch 40S, or Sch 80S. 
  • Standard Length: Distributed commercially in default 6-meter (20 feet) sections.
  • Surface Treatment Options: Offered in Mill Finish, Industrial Pickled, Satin Matte, or high-gloss Mirror Polish finishes.
  • Typical Applications
    • Oil, gas, chemical, and water distribution lines.
    • Heat exchangers, industrial boilers, and condenser units.
    • Architectural balustrades, staircase handrails, and durable modern furniture.
