BS 4504 Stainless Steel Welding Neck Flanges: High-Quality Connections for Diverse Applications

1. Product Description: BS 4504 Stainless Steel Welding Neck Flanges are precision-engineered components used to connect pipes or tubes in various industrial applications. These flanges feature a welding neck, which is designed to be welded to the pipe or vessel for a secure and leak-free connection. Made from stainless steel, they offer excellent corrosion resistance, strength, and durability, suitable for a range of pressures and temperatures.

2. Product Parameters:

Parameter Description
Type Welding Neck Flange
Sizes Customizable based on nominal pipe size (NPS)
Specifications As per client requirements or standard dimensions
Standard BS 4504
Material Stainless Steel (e.g., 304, 316)
Surface Treatment As-manufactured, passivated, or with a protective coating

3. Mechanical Properties:

Property Typical Requirements
Tensile Strength Varies with stainless steel grade, typically above 515 MPa
Yield Strength Typically above 205 MPa
Elongation ≥15% for most stainless steel grades
Hardness Varies depending on heat treatment and grade

4. Pressure Ratings:

Pressure Class Description
PN2.5 2.5 bar (36 psi)
PN6 6 bar (87 psi)
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 304 Stainless Steel Typical Range (%) for 316 Stainless Steel
Carbon ≤0.08 ≤0.08
Chromium 18.0-20.0 16.0-18.0
Nickel 8.0-10.5 10.0-14.0
Molybdenum - 2.0-3.0

6. Product Uses:

  • Chemical Processing: Ideal for chemical and petrochemical plants where corrosive fluids are handled.
  • Food and Beverage Industry: Suitable for hygienic applications in food processing and beverage production.
  • Pharmaceutical Industry: Employed in environments where cleanliness and purity are critical.
  • Power Generation: Utilized in power plants for steam and cooling systems.
  • Marine and Offshore: Used in marine applications due to their corrosion resistance in saline environments.

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.
