Understanding Stainless Steel Flange Thickness

Stainless steel flanges are essential components used to connect pipes and equipment in various industries. They come in different types and thicknesses, each suited for specific applications and pressure conditions. Here is an overview of the basic parameters and types of stainless steel flanges.

Basic Parameters

Operating Temperature Range: Up to 300°C
Impact Strength: 15 MPa
Material: 304.613 Stainless Steel
Pipe Diameter: DN15 to DN500 (mm)
Thickness: 10 to 50 mm
Applicable Fluids: Water, chemicals, steam, and more

Types of Stainless Steel Flanges

Stainless steel flanges are classified based on the connected parts and structural types:

Based on Connected Parts:
- Container Flanges
- Pipe Flanges
Based on Structural Type:
- Integral Flanges:
  - Flat Welding Flanges: These have lower rigidity and are suitable for applications with pressure up to 4 MPa.
  - Butt Welding Flanges (High Neck Flanges): These have higher rigidity, making them ideal for applications with higher pressure and temperature.
- Slip-on Flanges
- Threaded Flanges

Flange Sealing Surfaces

Flat Sealing Surface: Suitable for low-pressure and non-toxic media applications.
Concave and Convex Sealing Surface: Suitable for slightly higher pressure conditions.
