Stainless steel sealing flange

February 14, 2025

The following is information and recommended suppliers about stainless steel sealing flanges for your reference:

1、 Overview of Stainless Steel Sealed Flanges

Stainless steel sealing flange is a sealing component used for connecting pipes, valves, equipment, etc. It has the characteristics of corrosion resistance, high temperature resistance, and high strength, and is widely used in industries such as petroleum, chemical, food, and pharmaceuticals.

2、 Types of stainless steel sealing flanges

Classified by connection method

Plate Flange: Suitable for low-pressure pipelines, easy to install.

Weld Neck Flange: Suitable for high-pressure and high-temperature pipelines, with good sealing performance.

Threaded flange: Suitable for low-pressure, small-diameter pipelines, no welding required.

loose flange: Suitable for situations that require frequent disassembly.

Classify by sealing surface

Flat Face (FF): Suitable for low-pressure, non critical applications.

Raised Face (RF): The most common form of sealing, suitable for medium and high pressure applications.

Male Female Face (M/F): It has better sealing performance and is suitable for high-pressure applications.

Tongue and Groove Face (T/G): Suitable for situations with high sealing requirements.

Classified by Material

304 stainless steel: universal stainless steel with good corrosion resistance.

316 stainless steel: has stronger corrosion resistance and is suitable for highly corrosive environments.

321 stainless steel: excellent high temperature resistance, suitable for high temperature applications.

3、 Key points for selecting stainless steel sealing flanges

Pressure level

Select flange pressure rating (such as PN10, PN16, Class 150, etc.) based on the design pressure of the pipeline system.

Size specifications

Select flange size based on pipeline diameter (such as DN50, DN100, etc.).

Sealing surface form

Select the appropriate sealing surface form (such as RF, M/F, etc.) according to the sealing requirements.

Material selection

Select appropriate stainless steel materials (such as 304, 316, etc.) based on the characteristics of the medium.
