Classification and use of stainless steel flanges

Stainless steel flanges can be divided into the following categories according to their structure and use:

Flat flange: Flat flange is the most commonly used one, it has a simple structure, suitable for general pipe connection. Flat flanges are commonly used for piping systems in low pressure or non-critical environments.

Thread flange: thread flange is a kind of flange connected by thread, it has good sealing performance, suitable for high pressure and high temperature environment. The common standards for thread flange rings are BSPT, NPT, etc.

Butt welded flange ring: butt welded flange ring is a kind of flange ring connected by welding, it is usually used in high pressure, high temperature pipeline system, can provide better sealing performance and strength. Common standards for butt welded flange rings are ASME B16.5, DIN 2633, etc.

Blind flange ring: A blind flange ring is a closed flange ring used to seal an outlet in the piping system to prevent media from leaking or entering. Blind flange rings can be selected according to the need for flat blind, flange blind and other different forms.

Stretch flange: Stretch flange is a special type of flange, which has the function of adjusting the length or Angle, suitable for connecting two very close or offset piping systems.

Stainless steel flange According to different design requirements and use scenarios, the selection of the appropriate flange type can ensure the safe operation and sealing performance of the pipeline system. According to the pressure, temperature and medium of the pipeline system, the corresponding standard flange is selected, and the appropriate welding or threaded connection is carried out to meet the specific engineering requirements.
