Product Introduction
RF slip on plate flange is a common flange connection form.
RF face refers to Raised Face, which means there are protrusions at both ends of the flange to enhance the connection strength between the flange and pipelines, valves, etc.
Plate type flat welding flange is a flange formed by processing the pipes or equipment that need to be connected at both ends into a flat surface and then welding it.
Size
Sizes range from 1/2 inch to 80 inch, i.e. DN15 to DN2000
Pressure level range
Generally, it can withstand pressure levels ranging from 150LB to 2500LB.
RF plate welding flange is a common pipeline connection accessory, commonly used in high-pressure pipeline systems. It usually consists of two circular metal plates, fastened together by bolts, with a rubber or metal gasket sandwiched between them.
Application
1. Petrochemical industry: oil, natural gas, chemicals, etc
2. Industrial fields such as paper making, water treatment, and food processing
3. Construction, heating, ventilation, air conditioning and other fields
The RF face flat welding flange has reliable sealing performance and high pressure test ability, and is widely used in high-pressure pipeline systems and other environments that require reliable sealing.
Selection criteria
1. Size standards: There are many size standards for RF plate flange, and the appropriate size needs to be selected based on the actual situation. In general, the corresponding flange size is selected based on the diameter of the pipeline or equipment.
2. Material standards: There are also many types of materials for RF panel type flat welding flanges, including carbon steel, stainless steel, alloy steel, etc. When selecting, it is necessary to choose the appropriate material based on the usage environment and the properties of the medium.
3. Flange connection standards: The connection methods for RF flat flanges can be threaded connection, butt welding connection, etc., and suitable connection methods need to be selected according to actual needs.
4. Pressure bearing standard: The pressure bearing capacity of RF flat plate flange must comply with relevant national and industry standards, and cannot be lower than the required pressure bearing requirements.
5. Installation standards: The installation of RF panel type flat welding flanges needs to follow relevant installation standards and specifications to ensure installation quality and sealing performance.
