Butt welded ring loose flange
- Commodity name: Butt welded ring loose flange
- Product Description
-
Welding ring loose flange is a movable flange plate commonly used on water supply and drainage fittings. At the factory, there is a flange on each end of the expansion joint, which is directly connected to the pipeline or equipment in the project with bolts. Its design purpose is to save materials, and the structure is divided into two parts: one end of the pipe is connected to the pipeline, and the other end is made into a welding ring; The flange plate is made of low-grade materials, while the pipe part is made of the same material as the pipeline, thus achieving the goal of saving materials.
Advantages and disadvantages
Advantages:
● Save materials: When the pipe material is special and expensive, using butt welded ring loose flange can significantly reduce material costs.
● Wide applicability: Especially suitable for materials such as plastic pipes, fiberglass pipes, etc. that are not easy to weld or process.
● Easy to construct: Easy to connect and replace equipment, especially when it is inconvenient to align the flange bolt holes or to prevent changes in the flange bolt holes when replacing equipment in the future.Disadvantages:
● Low pressure bearing: The pressure bearing capacity of the welded ring loose flange is relatively low.
● Low strength at the welding ring: Especially when the thickness is below 3mm, the strength at the welding ring is low.
Application scenarios
Welding ring loose flange is commonly used in pipeline connections of special materials such as water supply and drainage systems, plastic pipes, fiberglass pipes, etc. Due to its design features, it can effectively reduce material costs and construction difficulties while ensuring connection strength.
