Flat Face Weld Neck Flange and ASME B16.5 Flat Flange Manufacturer in India
Unlike raised face flange or ring type flange, this device has a flat surface. The absence of a ridge is what gives it a flatter, smoother design. Because it has a flat surface, the gasket of the Flat Face Flange permits full, more uniform contact with the mating surface. Therefore, it is recommended to use a full face gasket for this type of flange.
The flat surface of this flange is also why it can’t be bolted with a flange that has a raised face. The ASME B16.5 Flat Flange is often used in piping systems whose valves or equipment are made from brittle or ductile material like soft iron. Unlike both ring joint and raised flanges, the Flat Face Weld Neck Flange can not be used for high pressure environments. The design ensures its use in low pressure applications such as water pumps or piping systems. Though its use is limited to low pressure, the materials used in the manufacture of any Alloy steel Flat Face Reducing Flange may have properties that prove useful in corrosive environments. Some environments contain salts of chlorine, the deposition of which could decay alloys due to the gradual depositional stress. This is why using a Stainless Steel Flat Face Flange in different grades will yield a better lifespan for the device. This type of flange is common in areas where bends in the piping systems are absent. The device is uniform in thickness all over, and so it works well in piping systems that have a straight orientation. For industries that need tougher, and harder materials, such as the oil and gas refineries, the economical Carbon Steel Flat Face Blind Flange is a suitable choice.
