Flanges can be of different types depending on the type of material used to make them. Here we will discuss two types, which are metal flanges and stainless steel flanges.

Metal Flanges

• An A234 Wpb flange is a circular disk that is welded to the end of a tube and allows it to be screwed to another tube. Generally used in water and fuel pipes, the two flanges will be screwed with a joint between them. The Flange will have screw holes around the entire perimeter and will be used to create splices, T-joints, and joints.


• When building a pipeline, the length of the pipes that will be used is not always known. By manufacturing the pipes separately from the A420 WPL6 flanges, welders can cut the pipes to size and weld a flange to join the pipes according to the length needed. The flanges can also be welded to the tubes with a slight inclination to allow two tubes that are not precisely aligned to join.


• The design of the flanges is uniform in a given size, regardless of the materials used to create them. This allows a black 15 cm pipe flange to match a stainless steel A350 LF2 flange perfectly. The flanges have a serrated finish on inside of the coupling surface, which allows the Flange to sit on the joint material. This assurance a perfect close up amid the two pipes.

Stainless Steel Flanges

• Metal flanges are ordinary in numerous applications, but under certain situations, some types of metal flanges are superior to others. A flange joint can use different materials due to the properties they possess. Among the different types of flanges, stainless steel flanges are a relatively popular choice because of their properties. Some examples of flanges, such as carbon steel, are susceptible to corrosion, commonly called rust. Stainless Steel Blind Flange is very opposed to corrosion and, as a result, can last longer than a carbon steel flange.


• Although the stainless steel flange is only one of the available types of metal flanges, it is usually the most popular. The size of flanges, as well as types of metal used in its construction, vary according to their application. Stainless steel flanges are easily incorporated into almost any flange system.


• The main reason for choosing stainless steel ASME B16.9 flange over other types of metal flanges is corrosion resistance and strength. Some metals are softer than others. Aluminum is softer than stainless steel. Under a great deal of stress, the aluminum flange may deteriorate, while the stainless steel flange will not. That kind of reliability makes the stainless steel flange a common choice in industrial applications.


• Although stainless steel flanges can cost more than other types of metal flanges, the reliability it offers is worth the investment. This B16.5 Flange must be available in a variety of sizes for a wide variety of applications. Because institutions regulate most metal flanges, it should be easy to replace one type of Flange with a stainless steel one, if necessary.
