Leave a message
When purchasing 304 stainless steel pipe, one of the most frequently asked questions is: "What is the weight per foot of 304 stainless steel pipe?" Knowing the accurate weight per foot is crucial, whether you are estimating material costs, calculating shipping fees, designing piping systems, or preparing project quotations.
This guide provides the standard formula for calculating the weight per foot of 304 stainless steel pipe, detailed weight charts for common pipe sizes, practical calculation examples, and expert advice on selecting the right ASTM A312 TP304 pipe for specific applications. Whether you are sourcing pipe for chemical processing, food production, construction, or oil and gas projects, this article will help you make informed purchasing decisions.
How To Calculate The Weight Of 304 Stainless Steel Pipe ?
Calculating the weight of a 304 stainless steel pipe is essential for estimating material costs, transportation loads, and structural requirements. The pipe weight is determined by its outside diameter (OD), wall thickness (WT), and the density of stainless steel.
Formula For Metric Units (Kg/M); Weight (kg/m) = (OD − WT) × WT × 0.0248
Example Calculation
For a 304 stainless steel pipe with:
Outside Diameter: 60.3 mm
Wall Thickness: 3.91 mm
Weight per meter:
(60.3 − 3.91) × 3.91 × 0.0248 = 5.47 kg/m
Therefore, the pipe weighs approximately 5.47 kg per meter.
Note: These formulas provide theoretical weights based on standard stainless steel density. Actual weights may vary slightly due to manufacturing tolerances specified in ASTM A312, ASTM A269, or other applicable standards.

What is the difference between sch 10 and sch 40?
The primary difference between Schedule (Sch) 10 and Schedule 40 pipes is wall thickness. Schedule 40 pipes have walls nearly twice as thick as Sch 10 pipes. Consequently, Sch 40 withstands much higher pressures and is heavier, while Sch 10 is more lightweight, less expensive, and easier to install.
What Is the Average Price of 304 Stainless Steel Pipe Per Foot?
For small- to medium-sized (1/2-inch to 6-inch) welded 304 stainless steel pipe, the average price ranges from $2 to $65 per foot, whereas the price for large-diameter or heavy-duty seamless pipe can exceed $100 to $300 per foot.

Does wall thickness affect 304 pipe cost?
Yes, wall thickness directly affects the cost of 304 stainless steel pipe. Pipes with thicker walls consume more raw material, resulting in a higher cost per foot. For instance, switching from Schedule 40 to Schedule 80 pipe can increase material and shipping costs by 30% or more due to the added weight.
Is 304 pipe cheaper than 316?
Yes, 304 stainless steel pipe is less expensive than 316 stainless steel pipe. 304 stainless steel is primarily composed of chromium and nickel and offers excellent durability in most standard, non-corrosive environments; while 316 contains the same base metals, it includes an additional 2% to 3% of molybdenum and a higher nickel content. Generally, the initial cost of 304 stainless steel is about 15% to 30% lower than that of 316.

SS 304 ERW Pipe vs. SS 304 Seamless Pipe: Key Differences
| SS 304 ERW Pipe | SS 304 Seamless Pipe | |
|---|---|---|
| Manufacturing | Cold-formed from flat coil, edges pressed and heated with electric current. | Extruded from a solid steel billet, drawn into a hollow tube. |
| Weld Seam | Yes, contains a visible longitudinal weld along the cross-section. | None; solid uniform construction throughout. |
| Pressure Rating | Lower; weld joint efficiency typically requires a 20-30% reduction in allowable working pressure. | Higher; uniform grain flow provides maximum strength and pressure resistance. |
| Surface Finish | Very smooth and uniform, bead can be polished flat. | Often rougher; requires additional cold rolling or drawing for a smooth finish. |
| Cost | Budget-friendly; typically 20–35% cheaper than seamless. | Costlier due to intensive manufacturing and raw material processes. |
| Ideal Applications | Structural support, architectural, low-to-medium pressure fluid/gas transport. | Oil & gas, refineries, high-temperature/high-pressure systems, critical corrosive environments. |
