Exceptional Chemical and Thermal Resistance

Designed for environments dealing with highly corrosive fluids, our lined jacketed pipes combine a polished or painted steel exterior with a chemically inert PTFE/PFA/FEP lining. This construction is highly resistant to most solvents, acids, and bases, making it perfectly suited for a range of industrial fluid transport needs. The self-extinguishing properties of the liner (UL 94 V-0) add an extra layer of safety in critical applications.

Custom Engineered for Your Process

We manufacture pipes to specific requirements regarding diameter, length, connection type, and lining thickness. Whether you need pipes for horizontal or vertical installation, we offer tailored solutions to fit your infrastructure. Each pipe undergoes strict dimensional tolerance checks (1 mm) and is hydrotested to ensure absolute leakproof integrity.

Easy Maintenance and Long Service Life

The smooth, chemically-resistant liner simplifies cleaning and reduces potential process contamination. Corrosion-resistant linings and jackets minimize downtime, maintenance costs, and the risk of leaksall critical for maintaining safety and operational efficiency in chemical, pharmaceutical, and petrochemical industries.

FAQs of Lined Jacketed Pipe:

Q: How is the lined jacketed pipe manufactured to ensure corrosion resistance and durability?

A: The manufacturing process combines extrusion or isostatic lining techniques for PTFE, PFA, or FEP liners with a fabricated carbon steel or stainless steel jacket. This dual-layer design, tested through hydrostatic pressure (10-15 bar), provides exceptional corrosion resistance and long-term durability, even when handling aggressive chemicals.

Q: What are the typical applications for lined jacketed pipes with PTFE/PFA/FEP lining?

A: These pipes are primarily used to transport corrosive fluids that also require precise temperature management in chemical, pharmaceutical, and petrochemical industries. Applications include handling acids, solvents, and other reactive chemicals in processes that involve heating or cooling through the steam jacket.

Q: When should I choose a lined jacketed pipe over a standard steel or plastic pipe?

A: Select a lined jacketed pipe when your process fluids are highly corrosive and temperature control is essential. The inner liner offers chemical inertness, while the jacket supports thermal regulation. This configuration is ideal for processes requiring leakproof assurance, low maintenance, and safety compliance.

Q: Where can lined jacketed pipes be installed, and what installation orientations are supported?

A: These pipes are engineered for flexible integration in both horizontal and vertical orientations. This adaptability makes them suitable for a wide range of plant layouts and piping schemes in industrial facilities worldwide.

Q: What customization options are available for lined jacketed pipes?

A: Customization covers diameter (DN25DN400), pipe length (up to 6 meters), lining and jacket thickness, connection type (such as flanged), outer color, and material grades (like A106 Gr.B, SS304, SS316, etc.). Special configurations for connection standards (ANSI, DIN) and thermal requirements are available on request.

Q: How easy is it to maintain and clean the PTFE-lined jacketed pipes?

A: Thanks to the non-stick, chemically-resistant inner surface, cleaning is straightforward and quick, significantly reducing maintenance frequency and minimizing process downtime. The durable liner prevents product buildup and contamination, which is essential in regulated industries.

Q: What are the benefits of using a steam-jacketed, PTFE-lined pipe regarding safety and reliability?

A: The combination of a fire-resistant, self-extinguishing PTFE liner and a robust steel jacket ensures safe operation in challenging environments. The leakproof design and high chemical resistance offer reliability, environmental protection, and extended service life, making them a preferred choice for critical process lines.
