Product material - stainless steel
AISI 304 (08X18H10), AISI 316 (03X17H12M2)
Free flat stainless flange
The free stainless steel flange according to GOST 12820-80 is a round flat part. The products are widely used in industrial production and all spheres of the national economy for connecting pipes, capacitive, pumping equipment, shut-off and control valves into a single system.
Details Features
According to the requirements of the State Standard, the dimensions of the stainless steel flange correspond to the dimensions of the pipes and parts of the equipment with which the connection is carried out. Acid-resistant steel grade 12X18N10T is used for the manufacture of these products.
Working characteristics of the part:
- pressure - from 0.1 MPa to 2.5 MPa;
- temperature - from -60°C to +600°C.
Depending on the application of the flange connection, a sealing surface corresponding to GOST 12815-80 is manufactured during the production process.
Main advantages
- The demand for a free flange is provided by a number of advantages.
- The flange connection is resistant to temperature changes.
- The products are easily mounted and replaced without stopping the operation of the entire pipeline.
- When installing fittings, it is not necessary to completely dismantle and disassemble all pipes.
- Stainless steel flanges are resistant to moisture, chemicals and aggressive environments.
- The parts withstand the high pressure of pipeline systems.
In compliance with the installation technology, flanged products will provide a strong and reliable fastening and increase the service life of the entire connecting system. Stainless steel flanges are widely used in pipelines of private farms, pipeline systems of housing and communal services, food, chemical, oil refining, metallurgical industry.
The company "ALFA-STAR" implements freestainless steel flanges that meet the State Standard. Choosing a suitable option, in accordance with the conditions of the upcoming operation, will not be difficult. The technical characteristics and parameters of the offered products are indicated on the website.
