Superior Chemical Resistance

PTFE lined dip pipes are constructed to withstand highly corrosive media. The inner PTFE lining offers exceptional chemical inertness, protecting the underlying steel and ensuring long service life, particularly in environments that challenge conventional materials.

Precision Engineering for Safety

Every PTFE lined dip pipe is manufactured with tolerances of 1 mm, ensuring precise fit and reliable, leak-free connections. Flanged ends with PTFE gaskets further boost sealing efficiency, minimizing the risk of contamination or leakage during transfer of hazardous materials.

Customizable for Diverse Applications

These dip pipes are available in various diameters (25 mm to 300 mm) and lengths (1m to 6m or as required), catering to the specific requirements of chemical, pharmaceutical, and petrochemical industries. The construction and grade selection provide flexibility and confidence in handling acids, solvents, and corrosive fluids.

FAQs of PTFE Lined Dip Pipe:

Q: How are PTFE lined dip pipes typically used in industrial processes?

A: PTFE lined dip pipes are primarily used for transferring corrosive chemicals, acids, and aggressive media from tanks or vessels in chemical, pharmaceutical, and petrochemical industries. Their robust design and PTFE lining ensure safe and contamination-free fluid handling.

Q: What are the benefits of using a PTFE lining in these dip pipes?

A: The PTFE lining offers excellent chemical resistance, high tensile strength (21 MPa), and a smooth, non-stick surface, protecting the steel structure from corrosion and extending the lifespan of the pipe, even when handling highly reactive or acidic substances.

Q: Where can PTFE lined dip pipes be installed?

A: These dip pipes are suitable for installation in process tanks, reactors, or storage vessels within facilities such as chemical plants, pharmaceutical manufacturing units, and petrochemical complexes, wherever safe transfer of corrosive substances is required.

Q: What is the standard process for manufacturing PTFE lined dip pipes?

A: Manufacturing involves selecting high-grade carbon steel or stainless steel pipes, applying a precision PTFE lining, and fitting fixed flanged connections. The pipes are machined to ASTM/ASME B16.5 or DIN standards, with strict quality checks for lining integrity, length, and dimensional tolerances.

Q: When should a PTFE lined dip pipe be chosen over other piping options?

A: PTFE lined dip pipes should be selected when conveying highly corrosive or acidic fluids that could degrade other materials. Their chemical inertness, high yield strength, and reliable sealing make them ideal for harsh process environments.

Q: How does the flanged connection contribute to the pipes performance?

A: Flanged connections, combined with a PTFE gasket at the joint, provide a secure, leak-proof seal. This setup allows for easy installation, timely maintenance, and ensures process safety during the transfer of hazardous or volatile chemicals.
