What is GOST flange?
The GOST flange follows the Russian GOST standard. The dimensions of the GOST flange varies with specifications and other standards. They are basically small to medium scale diameter flanges which are used in various applications. The stainless steel GOST flange can range between DIN 15 and DIN 1600. There are different types of GOST flanges used in different applications according to their structures. They are used in various industries like offshore oil industry, natural gas, oil fields, and water systems. They are available in the size range of ½” to 48”.

How to Select GOST flange
In order to select high-performance GOST flange, the buyers must consider its:

  • Quality of raw material- They should be of the best quality or the flanges will not be able to perform or get deformed in severe conditions.
  • Pressure rating- It is essential to check the pressure rating to understand if the given flange will be able to withstand the given nominal pressure.
  • Dimensional accuracy- This would help in proper sealing.
  • Design of the flanges- This would also help in the fitting and serve various purposes according to the structure.

Features of Ghost blind flange
The Features of Ghost blind flange are the same as that of a standard blind flanges. It helps in terminating the pipe run, and seals the connection at the end of the pipe. They are like steel plates without any central hub. They have bolted perimeters, which offers a tight seal. They are mostly placed in between the flanges, for stopping the flow. They are very useful if maintenance or repair works are needed inside the pipe.
