Product Overview

High-Temperature Corrosion-Resistant PTFE Lined Pipes & Fittings are designed for harsh chemical environments. Utilizing high-performance polytetrafluoroethylene (PTFE) lining, these products offer unparalleled chemical stability and resistance to extreme temperatures.

The low friction coefficient of the PTFE lining ensures smooth fluid transport, minimizing pressure drops. They are extensively used in chemical, petrochemical, power, and pharmaceutical industries for handling acidic and alkaline media.

Key Characteristics

Unmatched Corrosion Resistance: Resistant to almost all acids, bases, solvents, and salts.
Thermal Stability: Reliable performance from -50°C up to 200°C.
Durability: High aging and oxidation resistance for long-term service life.
Leak-Proof Design: Superior sealing performance reduces environmental and safety risks.

Technical Excellence

Electric Spark Detection

Internal Pipeline Cleaning

Manufacturing Capabilities

Our production line features advanced domestic testing and production facilities, including high-performance PTFE rolling coating and spraying equipment, dust-free lining workshops, and large-scale isostatic pressing equipment. This allows for the precise fluorinated lining of diverse industrial equipment specifications.

Packing & Delivery

Standard export packaging: Wooden Case Packaging. Gross weight and sizes are customized based on the pipe dimensions and quantity.

Frequently Asked Questions

Q1: Can the products be customized? A: Yes, we offer OEM/ODM services. We can customize specifications, sizes, and lining materials based on your specific engineering requirements.

Q2: How do I select the right corrosion-resistant material? A: Choice depends on your media type, operating temperature, and pressure. We offer PTFE, FEP, PFA, PO, and ETFE (F40). Our technical team can assist in selection.

Q3: What after-sales services do you provide? A: We provide comprehensive support including installation guidance, technical documentation, maintenance advice, and product warranties.

Q4: What are the main applications of PTFE lined pipes? A: They are primary used in chemical processing (acid/alkali transport), pharmaceuticals, power generation (corrosive gas handling), and wastewater treatment.

Q5: What is the standard pressure rating for these pipes? A: Our standard lined pipes are designed for an operating pressure range of 0.5 to 1.6 MPa, suitable for most industrial fluid transport.

Q6: Do you conduct quality testing before delivery? A: Yes, every pipe undergoes rigorous testing, including electric spark detection to ensure the integrity of the fluorinated lining and prevent leakage.
