Pipeline flanges - reliable industrial connections 

What is a flange?

(Flange)is a detachable element of a piping system used to connect pipes, valves, pumps and industrial equipment using bolts and gaskets. Flange connections are widely used inoil and gas, chemical, energy, shipbuilding, water treatment and engineering industries.

The main advantages of flanges compared to welded joints:

• ease of installation and dismantling;
• ease of maintenance;
• high tightness;
• Possibility of use under various conditions of pressure and temperature.

Main types of flanges

Depending on the design and application, the following types of flanges are used:

• Weld Neck, WN
  Designed for high pressure and temperature, widely used in the oil and gas industry.
• Flat weld flange (Slip On, SO)
  Economical solution for low and medium pressure pipelines.
• Blind Flange (BL)
  Used to shut off pipelines and conduct tests.
• Socket Weld Flange (SW)
  Suitable for small diameter and high pressure pipes.
• Threaded Flange
  Does not require welding, used in hazardous areas.
• Lap Joint Flange
  Convenient for frequent dismantling and alignment of pipes.

Flange materials

The choice of material determines the durability and safety of the pipeline system:

• Carbon steel(A105, Q235, A350 LF2)
  For use in standard industrial environments.
• Stainless steel(AISI 304 / 304L / 316 / 316L)
  It has high corrosion resistance and is suitable for the chemical and food industries.
• Alloy steel(A182 F11/F22/F51)
  Used at high temperatures and pressures.
• Low temperature steel
  Designed for use in low temperature conditions and LNG projects.

Flange Manufacturing Standards

We produce flanges in accordance with international standards:

• GOST (GOST)— Russia and CIS countries
• DIN/EN— Europe
• ANSI / ASME— USA
