SUS316L Stainless Steel Pipe: Standards, and Weight Chart

SUS316L stainless steel pipe is often the material of choice for applications requiring high corrosion resistance and excellent weldability. SUS316L is a low-carbon version of 316 stainless steel, making it particularly suitable for welding applications as it minimizes the risk of carbide precipitation during welding.

This article outlines relevant standards, including ASTM, JIS, and DIN, and provides a weight table for SUS316L pipes by size and specification to help you ensure compliance with global quality and regulatory requirements.

 

What are the standards for SS316 pipe?

SS316 pipes follow the ASTM A312 (seamless/welded) and ASME SA312 standards for stainless steel pipe, with 316L (low carbon) being a common variant. They comply with dimensional standards like ASME B36.19M (stainless steel pipe schedules) and are used for high corrosion resistance, featuring ~16-18% chromium, 10-14% nickel, and 2-3% molybdenum.

 

International Standards and Technical Requirements

SUS316L pipes must conform to major global standards, each with specific tolerances and performance expectations:

Standard	Region	Key Requirements
JIS G3459	Japan	OD ≤60.5mm: ±0.1mm; WT tolerance: ±10%
ASTM A312	USA/Global	NPS 1/8" to 24"; OD ±1% (large: ±1.6mm); WT ±12.5%
EN 10216-5	EU	Pressure pipe; OD ±1%; WT ±10%; NDT required
GB/T 14976	China	OD ±1%; WT ±10%; for chemical and power use
ISO 1127	Global	OD φ6-φ610mm; WT 0.5-50mm; custom shapes (e.g., oval)

 

 

How to Calculate the Weight of SS 316 Seamless Pipe?

The weight of a seamless pipe can be calculated using the following formula:

 

Weight (kg/m) = (π × (OD² - ID²) × density) / 4

Where:

π = 3.1416

OD = Outer Diameter (mm)

ID = Inner Diameter (mm)

Density of SS 316 = 8.03 g/cm³ (or 8030 kg/m³)

For example, if you have a pipe with an outer diameter of 50 mm and an inner diameter of 40 mm, the weight calculation will be as follows:

Weight (kg/m) = (π × (50² - 40²) × 8030) / 4
Weight (kg/m) = (3.1416 × (2500 - 1600) × 8030) / 4
Weight (kg/m) = 7.85 kg/m

This formula helps you calculate the weight of any SS 316 seamless pipe based on its size and wall thickness.

Below is a weight chart for commonly used SS 316 seamless pipes in various sizes. The weights are approximate and based on standard wall thickness.

Pipe Size (Inches)	Outer Diameter (mm)	Wall Thickness (mm)	Weight per Meter (kg)
1/2"	21.3	2	1.23
3/4"	26.7	2.3	1.55
1"	33.4	2.6	2.03
1 1/4"	42.2	2.8	2.57
1 1/2"	48.3	3.2	3.14
2"	60.3	3.6	4.34
2 1/2"	73.0	4	5.53
3"	88.9	4.5	7.14
4"	114.3	5	9.04
6"	168.3	6	13.64
8"	219.1	7.1	18.84
10"	273.0	7.6	25.02
12"	323.9	8	32.15

Note: The weights mentioned above are approximate and can vary slightly depending on specific pipe tolerances and the manufacturing process.

 

SUS316L Stainless Steel Pipe Applications

Industry	Recommended Spec	Standard	Key Requirements
Chemical Piping	φ219×8mm (SCH40)	ASTM A312	Sulfuric acid (≤5%), chloride resistance
Seawater Desal.	φ108×4mm (SCH80)	ISO 1127	Cl⁻ resistance, cathodic protection
