Engineered for Versatility and Reliability

Our plate flanges undergo advanced CNC machining and heat treatments such as normalizing, tempering, and annealing to ensure optimal performance across various operating conditions. With customizable dimensions and finishes, these flanges are suitable for projects demanding both high strength and corrosion resistance, making them ideal for industrial installations in India and abroad.


Comprehensive Testing and Quality Assurance

Every flange is subjected to rigorous 100% dimensional, hydrostatic, and visual inspections. We ensure our products meet and exceed industry standards (ANSI, DIN, JIS, BS, IS, EN, GOST). The result: peace of mind for customers seeking reliable pipeline components for critical infrastructure.

FAQs of Plate Flanges:


Q: How are plate flanges with flat face (FF) and raised face (RF) types manufactured?

A: Plate flanges are produced by CNC machining, drilling, and cutting processes to achieve precise dimensions and smooth surfaces. Flat face (FF) and raised face (RF) types are available, with custom bolt hole standards and finishes machined to meet specific application requirements.

Q: What material grades and thickness options are offered for these plate flanges?

A: We supply plate flanges in carbon steel, stainless steel, and alloy steel (ASTM A105, A182 F304/F316, IS 2062, EN1092-1), with thicknesses ranging from 5 mm to 60 mm. Customized grades and sizes are available upon request to fit unique project specifications.

Q: When is heat treatment such as normalizing or tempering applied to plate flanges?

A: Heat treatment processes, including normalizing, tempering, and annealing, are performed as required by the selected material grade and operating conditions to enhance flange strength, durability, and resistance to temperature variations (-29C to 600C).

Q: Where can these plate flanges be used, and in what industries are they commonly applied?

A: Our plate flanges are suitable for industries such as pipeline infrastructure, petrochemicals, water treatment, gas and oil, and general industrial projects. Their corrosion resistance and robust construction make them ideal for harsh and demanding environments.

Q: What testing and inspection procedures are conducted on the plate flanges before shipping?

A: Each plate flange undergoes 100% dimensional, hydrostatic, and visual inspection to ensure conformity to customer specifications and industry standards. This guarantees product reliability and performance.

Q: How are the flanges packaged and marked for delivery?

A: Flanges are packed in wooden cases, pallets, or customized packaging to ensure safe transport. Standard or custom markings are applied as per project requirements for easy identification on-site.

Q: What benefits and features do these plate flanges offer for installation and long-term use?

A: Our flanges provide high strength, durability, easy installation, and excellent corrosion resistance. With a purity greater than 99% metal content and rust-proof finishes, they ensure reliable, lasting service in diverse operational environments.
