PTFE Lined Pipe and Fittings

Use PTFE lined piping in any application where superior chemical resistance is required. Compared to other plastic pipe lining, PTFE has been proven to reduce permeation rates by up to 60%. It is also far more resistant to corrosion and high temperatures, and it features a full vacuum rating up to 450°F.

As a result, PTFE lined pipe and fittings are ideal for severe service applications, including pulp and paper processing, and power generation. Compared to exotic alloy materials or glass lining, PTFE is an economical choice that gets the job done right.

PTFE Lined Pipe

PTFE lined pipe provides unmatched chemical resistance at temperatures to 260ºC. Because its carbon chains are completely fluoronated, PTFE is chemically inert to the following broad range of commercial chemicals:

• All acids including hydrofluoric, hydrochloric, sulphuric and aqua regia
• Chlorides - organic and inorganic
• Sulphates - organic and inorganic
• Bleach solutions
• Solvents
• Phenols
• Caustics
• Peroxides

Combined with the chemical inertness of PTFE are its usual non stick properties. Thus a PTFE lined pipe system eliminates and/or minimises build up of deposits on the pipe walls, which otherwise would reduce flow and possibly affect processing operations.
