High Yield CS A694 Gr F65 Blind Flange and A694 F42 Weld Neck Flange manufacturer in India

What is ASTM A694 Flanges?
The ASTM A694 is a specification that describes carbon and alloy steel materials, used for making flanges primarily used for high pressure liquid transmission. The ASTM A694 Flanges are available in different grades, and they vary slightly in their mechanical properties depending on their chemical composition. Those grades are covered based on the minimum yield requirements. The material also adheres to the tensile property and testing requirements.
The ASTM A694 Flanges can be described as a method that helps in connecting valves, pumps, pipes and other equipment to form a complete piping system. With the help of these flanges, maintenance, cleaning, and inspection work across the pipeline becomes very easy. The flanges also help in quick modification of the piping system. The ASTM A694 Flanges can be installed either by welding or screwing them to the pipe. There are also flanged joints for this specification which helps to join to flanges by bolting the gasket present in between, this ensures that the flange is properly sealed to the piping connection. The ASTM A694 Flanges offer medium corrosion resistance but it has advantages in oxidizing media like nitric acid solution due to the presence of low molybdenum content in its alloy. They are also available in different faces that offer a wide range of functions according to their structure.

ASTM A694 GR. F52 Weld Neck Flange Vs ASTM A694 F60 Blind Flanges
The ASTM A694 GR. F52 Weld Neck Flange is suitable for high pressure applications. Due to their structure, they offer reduced friction and less interference. It can easily be aligned . Also, with a weld neck flange testing the pipes and joints become very easy. The ASTM A694 GR. F52 Weld Neck Flange offers durable connections, and with double welding (in both inside and outside), they offer a leakage proof connection. It is also very easy to install this weld neck flange, which is a major advantage.
The ASTM A694 F60 Blind Flanges looks like a plate that has some bolts holes in the surrounding area. There is no hole present in the middle of the flange, which differentiates it from the weld neck flange, and thus the blind flange helps in stopping the connection of a piping system. They basically help in sealing the ends of a pipe or the nozzle of a vessel. They have a great mechanical design that helps reduce the wear and pressure between the surfaces of the flange.

A694 GR.F42 Flange Vs ASTM A694 F70 Flanges
The chemical composition of A694 GR.F42 Flange and ASTM A694 F70 Flanges are different and hence their mechanical properties also vary. The F70 grade has enhanced mechanical properties such as high tensile strength, better heat resistance, enhanced corrosion resistance, and improved durability. They also possess better weldability and formability compared to the F42 grade.

What is ASTM A694 GR.F65 Flanges?
The ASTM A694 GR.F65 Flanges are very popular due to their high yield capabilities. They also possess excellent low temperature toughness and are known for their high weldability The mechanical properties of the ASTM A694 GR.F65 material would include:

  • 0.2% Yield Strength – 50 Mpa
  • Tensile Strength - 530 Mpa
  • Elongation - 20% min
  • Reduction of Area - 35% min

The ASTM A694 GR.F65 Flanges are available in various dimensions according to the international standards. They are also available in different pressure classes that range between 150 and 2500, and pressure number PN6 through PN64.
The ASTM A694 GR.F65 Flanges are available in different faces such as flat face, raised face and ring type joint flange. They are fit for different applications according to their structure. Due to the properties present in the ASTM A694 GR.F65 Flanges, they are widely used across several applications across industries like oil and gas, power generation, petroleum, boiler, condenser, and many more.
