Stainless steel collar flanges PN 64, manufactured according to GOST 12821-80 standard of stainless steel AISI 321 (12Х18Н10Т), are designed for connecting pipelines, pipeline valves and equipment in high-pressure systems. Collar flanges have a special protrusion (collar) that ensures even distribution of the load on the connection.
Manufacturing material: Flanges are made of stainless steel AISI 321 (12Х18Н10Т). This material has high corrosion resistance due to the content of chromium (about 18%) and nickel (about 10%).
Application of collar flanges made of AISI 321 (12Х18Н10Т) stainless steel:
- Used in the energy sector for steam pipelines and heat exchangers.
- Used in the chemical industry for transporting aggressive substances.
- Used in the oil and gas industry for working with oil, gas, and their derivatives.
- Suitable for the pharmaceutical industry due to the high corrosion resistance and hygiene of the material.
Advantages:
- High connection reliability due to the neck design.
- Resistance to deformation under high loads and pressures.
- Durability even under the influence of aggressive chemicals or extreme temperatures.
