Product Description
Schedule 40 SS 304 Stainless Steel Seamless Pipe
Stainless steel pipes offer excellent corrosion resistance and durability, making them ideal for various industrial applications requiring reliable pressure containment.
Pressure Calculation Methodology
The pressure capacity of stainless steel pipes is determined using the following calculation formula:
P = 2 × Wall Thickness × (Tensile Strength × 40%) / Outside Diameter
Material Specifications
- 304, 304L, 321 Stainless Steel: Tensile Strength = 520 MPa
- 316, 316L, TP316, TP316L Stainless Steel: Tensile Strength = 485 MPa
Pressure Rating Examples
Example 1: 304 Stainless Steel Pipe 159×3mm
P = 2 × 3 × (520 × 0.4) / 159 = 7.84 MPa
Example 2: 316 Stainless Steel Pipe 159×3mm
P = 2 × 3 × (485 × 0.4) / 159 = 7.32 MPa
