Sizes Customizable based on nominal pipe size (NPS)
Specifications As per client requirements or standard dimensions
Standard BS 4504
Material Carbon Steel, Stainless Steel (e.g., 304, 316), or other alloys
Surface Treatment As-forged, galvanized, painted, or coated with anti-corrosive material

3. Mechanical Properties:

Property Typical Requirements
Tensile Strength Typically above 400 MPa, depending on material grade
Yield Strength Typically above 240 MPa
Elongation ≥20% for most material grades
Hardness Varies depending on heat treatment and material grade

4. Pressure Ratings:

Pressure Class Description
PN10 10 bar (145 psi)
PN16 16 bar (232 psi)
PN25 25 bar (362 psi)
PN40 40 bar (580 psi)

5. Chemical Composition:

Element Typical Range (%) for Carbon Steel Typical Range (%) for Stainless Steel 304 Typical Range (%) for Stainless Steel 316
Carbon 0.15 - 0.30 ≤0.08 ≤0.08
Manganese 0.50 - 1.60 ≤2.00 ≤2.00
Phosphorus ≤0.045 ≤0.045 ≤0.045
Sulfur ≤0.045 ≤0.030 ≤0.020
Silicon ≤0.30 ≤1.00 ≤1.00
Chromium - 18.0 - 20.0 16.0 - 18.0
Nickel - 8.0 - 10.5 10.0 - 14.0

6. Product Uses:

  • Pressure Vessels: Used to close off the ends of pressure vessels.
  • Piping Systems: Ideal for creating a closed or "blind" end in a pipeline.
  • Industrial Plants: Employed in various industrial plants for maintenance and testing purposes.
  • Machinery and Equipment: Utilized in machinery that requires flanged connections.

7. Product Grade Standards:

  • BS 4504: The flanges are manufactured in compliance with the British Standard 4504, which specifies the requirements for steel flanges for pressure purposes.

Conclusion: BS 4504 Standard Blind Flanges are versatile and robust, offering a reliable solution for pressure applications where a sealed or closed end is required. Their adherence to BS 4504 ensures that these flanges are manufactured to high standards of quality and safety, making them suitable for a wide range of industrial uses.
