3.Practical examples with formulas
4.Tips to reduce procurement expenses
SS 316L Heat Exchanger Tube Specifications
Before calculating weight, you need these key tube parameters:
| Parameter | Description |
|---|---|
| OD (Outer Diameter) | Tube outer diameter in mm |
| WT (Wall Thickness) | Tube wall thickness in mm |
| L (Length) | Tube length in meters |
| Material Density | 316L stainless steel: 8.0 g/cm³ |
Example:A tube with OD 25.4 mm, WT 2.11 mm, and Length 6 m is typical in shell-and-tube heat exchangers.
2. Formula to Calculate SS 316L Tube Weight
The standard formula for cylindrical tube weight:
Where:
And:
Step-by-Step:
1.Calculate Inner Diameter (ID):
2.Calculate Cross-sectional Area:
3.Calculate Volume:
4.Multiply by Density (8 g/cm³) and convert to kg:
3. Example Calculation
Tube Specs:
OD = 25.4 mm
WT = 2.11 mm
Length = 6 m
Step 1: Calculate ID
Step 2: Cross-sectional Area
Step 3: Volume
Step 4: Weight
