Advantages of Large Diameter Flanges
Large diameter flanges have the following advantages:
Large-diameter flanges that are properly installed are corrosion-resistant and have a wide range of media applications.
Because of their ease of installation, they are suitable for any climate. Because of their huge sealing surface areas, they are simple to install, even underwater.
The use of elastomeric sealing gaskets extends the life of these flanges to at least 50 years.
When correctly made, they provide long-term protection against corrosion, abrasion, and impact to ensure continuous reliable operation.
The Welding Process for Flanges with Large Diameters
Large-diameter flanges by Large Diameter Flanges Supplier are typically used to strengthen and connect tank equipment and large-scale furnaces. This type of equipment is often built in small batches or as a single piece, rather than as a commodity production run. For plate flanges, the traditional method is to cut the circular plate to the size of the entire steel plate. The inner-circle on the circular plate must then be cut off. The process method is easy, but it requires operating space and large black size, therefore it is beneficial to include a large diameter flange, which will result in low economic benefit and material usage. For large-diameter slip-on with hubs and weld necks, forgings are necessary.
The flange must be drilled to accommodate bolt holes for a rubber sealing ring and another flange inserted in the middle. End-user applications typically require a larger flatness tolerance of the flange to ensure the sealing effect, and the overall thickness of the flange plays a supporting function. As a result, the dimensional tolerance and roundness of the flange’s outer and inner holes are not as high as in smaller flanges.
