Fluoropolymer / PTFE / FEP / PFA Lining on Pipe Fittings , Bends , Tees & Valves
PTFE Lined Pipe & Fittings
Our Fluoropolymer-lined speciality fittings are constructed from high-temperature corrosion resistant
Fluoropolymer, including: PTFE, PFA, ETFE and PVDF
PRODUCT RANGE
Lined Pipe Spools
- 5mm - 150mm nominal bore up to 6000mm length
- 200mm - 300mm up to 3000mm length
- 350mm - 600mm up to 2000mm length
- Supplied with one fixed and one rotating flange to accommodate any bolt hole misalignment.
- Close fitting PTFE liners to increase surface life and performance.
- Spools will be supplied to the length specified by the customer
- If site fabrication is essential, pipes with loose liners together with portable flaring equipment can be supplied.
Lined Fittings
- 5mm - 150mm nominal bore up to 6000mm length
- Alternatively they can be fabricated from carbon steel pipe, flanges and Boilerplate.
- One or more rotating flanges on carbon steel fittings if required.
- Fittings are lined with moulded PFA linings or PTFE.
- All fittings are interchangeable within the ANSI #150 or 300 or DIN 2848 specifications
- Special fittings can be designed and manufactured if required.
The Fluorocarbon system is designed to handle, with safety, most highly corrosive and hazardous fluids over a wide temperature range. The system combines the strength of traditional metal pipework with the inertness of selected plastics materials to severe environmental conditions.

Antistatic Liners
- HD - Heavy Duty: A thicker liner suitable for pressure and vacuum service throughout the temperature range. Also recommended for searching gaseous media.
- Heavy Duty Antistatic liners are available in PTFE/PFA to meet the requirements of process industries handling flammable materials.
- The electrical conductivity of the liner material is increased so that the volume resistivity is not greater than 106 ohm-cm.
- Antistatic liners are black.
