ASTM A182 F1 Flange

ASME SA182 Grade F1 Forged Flanges and Gr 1 Alloy Steel casting manufacturer in India

What is ASTM a182 grade f1?
The ASTM a182 grade f1 can be defined as the forging material specification for the alloy steel of grade F1. The material is primarily used for manufacturing bare forgings along with forged / machined products for applications occurring at elevated temperatures.

What are the different Faces of astm a182 Gr f1 Flanges?
The astm a182 Gr f1 Flanges comes with different types of faces, like:

Raised Face- this is the most common type of flange face used especially in applications of process plants. The shape of this flange face helps in concentrating more pressure on a smaller gasket area, which in turn, increases the joint’s pressure containment capabilities.
Flat Face- Here, the bolting circle face and the gasket surface are on the same plane.
Ring Type Joint Face- They are typically used in applications taking place at high temperatures (above 427 degrees C), and/or high pressure (class 600 and higher ratings).
Tongue and Groove- They come with two faces, tongue and groove, which should be matched to join. They are mostly found in valve bonnets and pump covers.
Male and Female- These are also two flanges which need to be matched. They are mostly found in heat exchanger shell for channeling and covering the flanges.

What is the difference between SA 182 F1 slip on and ASTM A182 F1 weld neck flange?
The SA 182 F1 slip-on flange is double welded to the pipe , one on the back side and the other on the inside of the flange. Even though the cost of the slip-on flange is less compared to the weld neck flange initially, the double welding along with inspections, add up to the overall cost. The strength of the SA 182 F1 slip-on flange under internal pressure is about two-third and its fatigue life is about one-third, when compared to that of a weld neck flange.
The ASTM A182 F1 weld neck flange can be easily recognized by its tapered hub. They have a specific bore which helps to mate with the concerned pipe or fitting. The connection is established through full penetration, which helps in preveh\nting any kind of turbulence at the joint. It also helps in reducing any type of erosion and all restrictions to the flow of product. The ASTM A182 F1 weld neck flanges are known for their enhanced strength under high pressure, cryogenic or elevated temperatures.

What is ASME SA182 Grade F1 Forged Flanges
When thermal or mechanical energy is applied to the ASME SA182 Grade F1 steel billets, the procedure is known as forging. The ASME SA182 Grade F1 Forged Flanges have a consistent structure and composition. They are very strong and reliable due to the alteration of grain flows in the steel. They come with a tight grain structure, which makes the forged flanges mechanically strong and wear and tear resistant.
