Stainless Steel Pipe Weight Chart: Complete Guide to Stainless Steel Pipe Weight Calculation
A Stainless Steel Pipe Weight Chart lists the theoretical weight (in kg per meter) of stainless steel pipes based on outside diameter, wall thickness and pipe schedule. To calculate pipe weight manually, use the formula: Weight (kg/m) = (OD − Thickness) × Thickness × 0.02491. This helps engineers, fabricators and buyers estimate material requirements, transportation costs and structural loads before ordering.
Stainless Steel Pipe Weight plays a critical role in project estimation, transportation planning, fabrication, structural design and procurement. Engineers, contractors and purchasing teams often rely on an accurate SS Pipe Weight Chart to determine weight per meter, total project load and material requirements before placing an order.
Whether you need an SS Pipe Weight Chart in KG per Meter, a 304 Stainless Steel Pipe Weight Chart, a 316 Stainless Steel Pipe Weight Chart, or guidance on stainless steel pipe weight calculation, this guide covers everything you need to know. You'll learn how to read a weight chart, use the standard SS pipe weight formula and calculate stainless steel pipe weight accurately for industrial applications.

Stainless Steel Pipe Weight Formula
The standard formula for calculating the theoretical weight of stainless steel pipes is:
Where:
- OD = Outside Diameter (mm)
- Thickness = Wall Thickness (mm)
- 0.02491 = Stainless Steel Density Factor
This formula is widely used for both stainless steel seamless pipes and welded stainless steel pipes.
Pipe Weight Calculation Example
Given:
- OD = 60.3 mm
- Wall Thickness = 3.91 mm
Calculation:
Weight ≈ 5.49 kg/m
This result closely matches standard Schedule 40 stainless steel pipe weight tables.

Stainless Steel Seamless Pipe Weight Chart
The Stainless Steel Seamless Pipe Weight Chart provides theoretical weight values for seamless pipes manufactured according to ASTM A312 and ASME B36.19M standards. Pipe weight is calculated using the outside diameter, wall thickness, and schedule rather than the manufacturing process. For identical dimensions, seamless pipes follow the same weight calculations shown in the chart above.
Industries Using Seamless Pipes
- Oil & Gas
- Refineries
- Power Plants
- Petrochemical Facilities
Stainless Steel Welded Pipe Weight Chart
The Stainless Steel Welded Pipe Weight Chart is used to estimate the weight per meter of welded stainless steel pipes. Theoretical weight depends on pipe dimensions and schedule, not on whether the pipe is welded or seamless. Therefore, welded pipes with the same OD and wall thickness generally have the same calculated weight as seamless pipes.
Common Applications
- Structural Projects
- Water Distribution Systems
- Decorative Applications
- Industrial Fabrication
Seamless vs Welded Pipe Weight Chart
Both seamless and welded stainless steel pipes use the same weight calculation formula, so the SS Seamless Pipe Weight Chart and SS Welded Pipe Weight Chart provide identical theoretical weight values when the outside diameter, wall thickness, and pipe schedule are the same. The difference between seamless and welded pipes lies in their manufacturing process and application, not in their calculated weight.
Stainless steel seamless pipes are manufactured without welded joints and are preferred for high-pressure, high-temperature, and critical service applications such as oil & gas, refineries, power plants, and petrochemical facilities.
Stainless steel welded pipes are produced by forming and welding stainless steel strip or plate. They are cost-effective and widely used in structural projects, water distribution systems, industrial fabrication, decorative applications, and general process piping.

Talk to Our ExpertsFrequently Asked Questions
You can calculate stainless steel pipe weight using the formula: Weight (kg/m) = (OD − Thickness) × Thickness × 0.02491. Where OD is the outside diameter in millimeters and thickness is the pipe wall thickness in millimeters.
The weight of an SS 304 pipe per meter depends on its outside diameter, wall thickness, and schedule. For example, a 2" Schedule 40S SS 304 pipe weighs approximately 5.44 kg/m.
No. SS 304 and SS 316 have very similar densities, so the weight difference is negligible when the pipe dimensions and schedules are the same.
Schedule 40 stainless steel pipe weight varies according to pipe size and wall thickness. For example, a 2" Schedule 40S stainless steel pipe weighs approximately 5.44 kg per meter.
A stainless steel pipe weight chart helps engineers, contractors, and procurement teams estimate material quantities, transportation costs, structural loads, and project budgets accurately.
Theoretical pipe weights are reliable for estimation and planning purposes. Actual weights may vary slightly due to manufacturing tolerances, dimensional variations, and material specifications.
Stainless steel pipes are widely used in oil & gas, chemical processing, pharmaceuticals, food processing, marine applications, water treatment plants, power generation, and petrochemical industries.
Most leading stainless steel pipe manufacturers, suppliers, and stockists in India provide SS Pipe Weight Charts and dimensional data for ASTM A312 TP304, TP304L, TP316, and TP316L stainless steel pipes.
Not significantly. Since SS 304 and SS 316 have nearly identical densities, the 304 Stainless Steel Pipe Weight Chart and 316 Stainless Steel Pipe Weight Chart show almost the same weight values for identical dimensions and schedules.
The primary factors affecting stainless steel pipe weight are outside diameter (OD), wall thickness, pipe schedule, and pipe length. As wall thickness and diameter increase, the pipe weight also increases.
