Superior Corrosion Resistance for Challenging Environments

Combining a strong carbon steel core with 35 mm FEP or PFA seamless lining, these bends offer outstanding protection against a wide spectrum of acids, alkalis, and solvents. This makes them highly suitable for transferring extremely aggressive and high-purity fluids in critical process applications.

Engineered for Precision and Reliability

Each bend is hot formed for seamless lining, professionally hydrotested up to rated pressures, and visually inspected 100% to guarantee product integrity. The drilled flanged connections meet ASA, BS, and IS standards, offering flexible integration and secure fitting in diverse pipeline systems.

Versatile Customization and Consistent Performance

Available in a range of diameters (DN25DN300), angles (45/90/custom), colors, and lining thicknesses, our FEP-PFA Lined Bends can be tailored precisely to your needs. They deliver long-term durability and minimal maintenance in chemical, pharmaceutical, and food industry environments.

FAQs of FEP-PFA Lined Bend:

Q: How is the FEP-PFA lined bend constructed to ensure corrosion resistance?

A: The bends carbon steel body is seamlessly lined with a 35 mm layer of FEP or PFA using a hot-formed manufacturing process. This method guarantees a continuous, pinhole-free lining that prevents corrosive media from contacting the metal, ensuring superior resistance to acids, alkalis, and solvents.

Q: What industries commonly use these lined bends and why?

A: These bends are widely adopted in the chemical, pharmaceutical, and food sectors due to their ability to safely handle highly aggressive or ultra-pure media. Their robust design and exceptional corrosion resistance make them ideal for processes where media purity and containment are crucial.

Q: When should I specify a custom bend angle or diameter?

A: Custom angles and diameters are recommended when standard options (such as 45 or 90 angles, or DN25DN300 size) do not match your piping layout or process requirements. Customization ensures seamless integration with your existing system and optimal flow performance.

Q: Where are these bends manufactured and to which quality standards?

A: Our FEP-PFA lined bends are manufactured in India, adhering to rigorous ASTM, DIN, and ASME B16.5 standards. Each product undergoes full visual and hydrostatic inspection to confirm compliance and quality.

Q: What testing and inspection processes are performed on these bends?

A: Every bend is visually inspected 100% and hydrotested up to the rated pressure to ensure there are no leaks or material defects. This rigorous quality assurance ensures reliable performance in demanding applications.

Q: How do I benefit from using FEP/PFA lined bends in my pipeline system?

A: Using FEP/PFA lined bends offers enhanced lifespan, minimal maintenance, and reduced risk of leaks or contamination. Their resistance to chemical attack significantly lowers downtime and maintenance costs compared to unlined or traditional metal piping.

Q: What is the typical process for ordering and installing these lined bends?

A: You can specify dimensions, angle, lining thickness, flange standards, and color as per your requirement. Installation is straightforward via flanged connections, making integration into new or existing pipelines efficient and secure.
