Threaded Flange

Overview

Threaded Flanges are designed for piping systems where welding is not possible or not preferred. Pipes are connected by internal threads, allowing for easy installation and disassembly.

They are especially suitable for small-diameter, low-pressure pipelines and for applications where frequent maintenance or replacement is required.

Manufactured in accordance with international standards, our Threaded Flanges are widely used in oil & gas, chemical, water treatment, and industrial piping systems worldwide.

Product Features

  • Non-Welded Connection: Internal threads allow direct connection to threaded pipes without welding.

  • Easy Installation & Maintenance: Ideal for systems requiring frequent assembly and disassembly.

  • Cost-Effective Solution: Reduced installation cost compared to welded flanges.

  • Material Options: Available in Carbon Steel, Stainless Steel, Alloy Steel.

  • Size Range: DN15 – DN300 (1/2" – 12").

  • Pressure Ratings: ASME Class 150 – 600; PN 6 – PN 40.

  • Manufacturing Method: Forged and machined for precise threading and smooth surface finish.

  • Custom Fabrication: Available according to drawings or project specifications.

Standards Compliance

Our Threaded Flanges are manufactured according to major international standards:

  • ASME B16.5 – American flange standard

  • EN 1092-1 – European standard

  • DIN / JIS – Optional for European & Japanese projects

  • GOST 12820 / GOST 12821 – Russian standard

  • Custom Standards – Available upon request

Ensures safe and reliable operation in low-pressure piping systems.

Materials & Grades

  • Carbon Steel: ASTM A105, ASTM A350 LF2

  • Stainless Steel: ASTM A182 F304 / F316

  • Alloy Steel: ASTM A182 F11 / F22

Materials are selected to provide good mechanical strength and corrosion resistance.

Applications

Threaded Flanges are widely used in:

  • Low-pressure piping systems
