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.
