The flanges which are being discussed contain several properties, out of which the heat hardening one is distinct. The weldability of these alloys makes it easier to be welded into different sizes and dimensions for a particular use. Stress corrosion is a severe issue when operating under rigorous conditions and alloy steel blind flanges are resistant to this form of corrosion. The capacity of the flanges to endure extreme pressure has been utilized in several applications which are subjected to rigorous conditions. The corrosion resistance it exhibits against acids and liquid solvents is also an impressive property of the blind flanges.
With excellent traits displayed by the flanges in extreme conditions, it finds itself a lot of applications, some being; Off-Shore Oil Drilling, Gas Processing, Chemical Industries, Sea Water Equipments, Power Plants, Food Industries, Condensers, etc.
The quality of the flanges has a strong chance of getting degraded during the manufacturing process or during delivering and handling the flanges. To avoid this, we take every necessary precaution, but it still manages to affect a few ones. Therefore, to ensure
