Plate flange VS SO flange
There are many different types of flanges on the market. For example, butt welding flanges, sliding sleeve flanges, butt welding flanges, plate flanges, and blind flanges. Today, we will learn about two types of flanges-plate flanges and sliding sleeve flanges.
What are Plate flanges?
A plate flange is a flat disc welded to the end of a pipe, allowing the flange to be bolted to another pipe. Usually called flat flanges, flat flanges, and flange slips. Two plate flanges can be bolted together, with a gasket between them, usually used for fuel and water pipes.
When constructing pipelines, the length of the pipeline is not always known. It is also possible to weld the plate to the shaft with a slight deviation to the shaft, thereby connecting two pipes that may not be perfectly matched.
The inner mating surface of the plate flange has a serrated finish, which enables the plate to be installed in the gasket material. In any given size, regardless of the material used to make them, the plate flange design is standardized. This ensures that it exactly matches the 6-inch (15 cm) black pipe flange to the 6-inch stainless steel flange. This guarantees a perfect seal between the two connecting pipes.
What are Slip-on flanges?
Slip-On flanges are also called SO flanges, or reducers, long cut elbows and swag are used to slide on the outside of the pipe. The flange has low vibration and shock resistance. Aligning the sliding sleeve flange is simpler than any other flange. Sliding sleeve flanges are suitable for low-pressure applications because the strength under internal pressure is about one-third of that of butt-welded flanges. The slide-in flange has a raised profile.
Sliding flanges or SO flanges are generally lower in cost and therefore become a common choice for customers. Fillet welds are usually welded to the back or outside of sliding sleeve flanges or SO flanges. Because of their lower initial cost, they are more favored by many consumers than other flanges, but due to the additional welding involved, the final installation cost may not be much lower than other flanges.
