What are stainless steel flanges?

As the name suggests, stainless steel flanges are flanges made of an alloy called stainless steel.

Here is why stainless steel flanges are worth your investment:

  1. Corrosion resistance : 

Corrosion is a major problem for clients using flanges due to chemicals and environmental factors. Therefore, it is ideal to choose stainless steel flanges that can withstand these conditions. Stainless steel is a great choice as it is highly resistant to corrosion.

  1. Durability:

Stainless steel is one of the most durable alloys and can withstand harsh environmental conditions.

  1. Tolerance to extreme temperatures:

Flanges made of stainless steel can withstand high temperatures. Some grades can withstand scaling and can maintain their strength even at very high temperatures, while others show excellent durability at extremely low temperatures.

  1. Aesthetics:

Stainless steel flanges are available in a variety of surface finishes which gives them an aesthetic look. It is easy to clean and maintain, resulting in high quality, attractive appearance.

Stainless steel flanges are available in a wide variety of grades of stainless steel. Each grade differs in chemical composition and has different properties. There are various grades of stainless steel flanges available to suit the client’s requirements. One must put its intended applications into consideration when choosing the grade of stainless steel flange to use. For example liquids, gases, etc.)

What are the applications of stainless steel flanges?

There are several types of stainless steel flanges available in the market, each having different uses:

  • Weld Neck Flanges: these are ideal for severe service conditions such as high pressure.
  • Threaded Flanges: ideal for low pressure and temperature requirements.
  • Slip-on Flanges: suitable for tasks involving low pressure.
  • Lap Joint Flanges: ideal for systems that undergo regular inspection and maintenance.
  • Socket Weld Flanges: these are durable and are ideal for small diameter and high-pressure piping
  • Ring-Type Joint Flanges: suitable for high temperature and high-pressure requirements.
  • Orifice Flanges: these are used for accessing the line that helps to meter liquids or gases.
  • Blind Pipe Flanges: used to seal the ends of pipes or pressure vessel openings.
  • Reducing flange: used to connect one pipe to the other.
