In daily life, flanges are more common and there are many kinds, so what is the basic theory and application of the welded ring loose flange, the flat welded ring loose flange and the threaded flange in the loose flange
There are two types of loose sleeve flanges
Butt welded ring loose sleeve flange: butt welded ring loose sleeve flange is a movable flange, usually matched on the water supply and drainage parts, flange manufacturers when the expansion joint on each end of the flange, immediately with the project in the pipeline, facilities with bolts.
The function depends on: the purpose of using the butt welded ring loose sleeve flange is usually to save material, and the next two parts of the structure, one end of the pipe part and the pipe connection, one end of the butt welded ring.
The flange is made of low-grade material, and the pipe part is used and the pipe is favorable to the material, which saves the purpose of saving the material. Advantages: cost saving, conducive to engineering construction, when the pipe material is special
Welded ring loose sleeve flange: The flat welded ring loose sleeve flange is a flange that can move, and is immediately connected with the pipeline and facilities in the project with bolts.
The purpose of using the flat welding ring to loosen the flange is usually to save materials, and the two parts of the structure are connected to one end of the pipe and the pipe, one end is made of flanging, and the flange part is set on the edge.
Advantages: It is convenient for welding or processing, or the required strength is large, which is conducive to engineering construction, such as the corresponding flange bolt holes during connection are convenient to find the right or avoid changes in the flange bolt holes of the replacement equipment in the future. When the price is high, save money. When the pipe material is special, the cost of welding the flange of the same material is relatively high.
Scope of application of loose sleeve flange
The application area of the loose sleeve flange is often seen in the condition that the material temperature and pressure are not high and the material corrosion is strong, when the material corrosion is strong, the part of the flange touching the material is a corrosion-resistant high-grade material such as stainless steel material and other materials, and the external use of low materials such as carbon steel material flange ring clamp it to complete the seal
