Alloy 20 Lap Joint flanges are a special type of pipe fitting used to join two piping sections without welding. They consist of a hub-like body, which is circular in shape and has two rim projections extending outward from the center. These projections are typically made from either carbon steel or stainless steel and give the material strength and durability. The main advantage of ANSI B16.47 lap joint flanges over traditional slip-on flanges is that they can be easily installed or removed with relative ease, as no welding is required. Additionally, these fittings provide higher levels of corrosion resistance than most other types due to their metallurgical properties.
