Outstanding Chemical Resistance

With a minimum 3 mm thick PTFE lining produced from virgin material, this concentric reducer ensures exceptional resistance to a vast range of acids, alkalis, and solvents. This feature makes it ideal for environments that demand reliable transfer of corrosive or hazardous chemicals, thereby increasing system lifespan and safety.

Precision Engineering & Stringent Standards

Every PTFE Lined Concentric Reducer is manufactured in ISO 9001:2015 certified facilities in India, with precise tolerances of 1 mm and adherence to international standards like ASTM F1545, ASME B16.5, and ANSI B16.5 for flanged connections. Each unit undergoes thorough hydro, leak, and spark tests to guarantee maximum lining integrity and performance.

Versatile Application & Durability

Suited for piping systems in chemical, pharmaceutical, and water treatment sectors, this reducer covers diameters from DN25 to DN300 and lengths from 150 mm to 400 mm. The robust body and high-grade PTFE lining ensure both mechanical strength and long-term durability even under full vacuum or high pressure situations.

FAQs of PTFE Lined Concentric Reducer:

Q: How is the PTFE lining applied to the concentric reducer?

A: The PTFE lining on each reducer is installed using advanced paste extrusion and isostatic moulding processes. This ensures a uniform, defect-free lining with a minimum thickness of 3 mm, offering excellent durability and corrosion resistance.

Q: What industries commonly use PTFE Lined Concentric Reducers?

A: These reducers are widely used in chemical processing, pharmaceutical manufacturing, and water treatment plants where the safe transfer of corrosive or hazardous chemicals is required.

Q: When is it necessary to use a PTFE lined reducer instead of a standard metal one?

A: A PTFE lined reducer is essential when dealing with aggressive chemicals that could corrode standard metal fittings, ensuring reliable service life and preventing leaks or system failures.

Q: Where is this product manufactured and what quality standards does it comply with?

A: Manufactured in India by ISO 9001:2015 certified facilities, each reducer is carefully tested in accordance with ASTM F1545 and ASME/ANSI B16.5 standards for quality and performance assurance.

Q: What is the process for testing lining integrity and pressure rating?

A: Each reducer undergoes 100% spark testing to verify lining integrity and is hydrotested at 1.5 times the design pressure, ensuring it is fit for rated vacuum and pressure conditions.

Q: What are the user benefits of selecting this PTFE lined reducer?

A: Users benefit from outstanding resistance to chemical attack, reliable performance in vacuum and high-pressure environments, long service life, and reduced maintenance compared to non-lined alternatives.
