Lap Joint Flanges
The hubs are typically taller than a slip on style and can be modified per your requirements. Slip ons in higher pressure classes are often made with the height of a lap joint for a better connection. If the hub height is not a concern and a lap joint is not readily available, customers will sometimes opt for a slip on made to a lap joint style with a machined hub.
Often times, a stub end will be made of a special material grade (nickel alloy), with the lap joint consisting of basic carbon or commodity stainless, in order to reduce the overall cost of the connection. Naturally, we recommend that both items are of the same grade for the purposes of uniformity, but your application will determine what’s best and/or necessary.
Lap Joint Flanges and Rolled Angle Rings
Various industries, including piping and structural applications, use industrial flanges. Lap Joint Flanges and Rolled Angle Rings are two components that play crucial roles in numerous operations.
The primary difference between lap joint flanges and rolled angle rings is that rolled angle rings are only available in a butt-weld configuration. On the other hand, Lap joint flanges come in both butt-weld and slip-on variations. In contrast to the backing flange on a rolled angle ring, the backing flange on a lap joint flange is free to rotate.
Lap Joint Flanges
1) Lap joint flanges are a two-piece design with a backing flange and a rolled angle ring.
2) It is available in butt-weld and slip-on configurations.
3) Different materials are used for the backing flange and the rolled angle ring.
4) The backing flange allows for easier alignment because it is free to rotate.
Rolled Angle Rings
1) Rolled angle rings is a two-piece design with a rolled angle ring and a backing flange
2) It is available in butt-weld configuration.
3) Just like Lap joint flanges, different materials are used for the rolled angle ring and the backing flange
4) The backing flange is not free-to-rotate in roll angle rings compared to lap joint flanges.
Which Type of Fitting is Right for you?
Choosing the right flanges for your industrial application is crucial. It entirely depends on the requirement of the intended application.
Lap joint flanges are suitable for piping systems, allowing easy disassembly, while rolled angle rings are suitable for structural applications to create curved or rounded shapes within various structures.
Examine your project requirements and prepare a list. If you need a fitting that can be effortlessly assembled, disassembled, or made from different materials, then a lap joint flange is an ideal choice.
Are you looking for something more rigid and challenging to disassemble? A rolled-angle ring is the best choice for you.
Texas Flange stocks a wide variety of flanges in all sizes and specifications.
