PTFE (Polytetrafluoroethylene) lined pipes are used extensively in various industrial sectors due to their remarkable chemical resistance and high-temperature handling capabilities. Below, we explore their benefits and applications:

Chemical Resistance

PTFE is almost universally chemical-resistant, making PTFE lined pipes ideal for transporting aggressive and corrosive substances, such as acids, bases, solvents, and other harsh chemicals.

High Temperature Tolerance

With the ability to withstand temperatures up to approximately 260°C (500°F), PTFE lined pipes are suitable for processes that involve significant heat.

Low Friction

PTFE has one of the lowest friction coefficients of any solid material, contributing to reduced pressure losses and enhanced flow efficiency.

Non-stick Properties

The non-stick nature of PTFE ensures that materials do not build up inside the pipe, guaranteeing smooth flow and minimizing the need for frequent cleaning.

Electrical Insulation

PTFE is an excellent electrical insulator, which can be advantageous in applications where minimizing electrical conductivity is critical.

Applications in Various Industries

Chemical Processing

Used for transporting highly corrosive chemicals like sulfuric acid, hydrochloric acid, and caustic soda.

Pharmaceuticals

PTFE lined pipes handle solvents and active pharmaceutical ingredients without the risk of contamination.

Food and Beverage

They convey food-grade products and cleaning chemicals safely, thanks to PTFE's non-reactive and non-contaminating properties.

Water Treatment

These pipes are used for transporting chemicals in water purification processes.

Oil and Gas

Handling aggressive chemicals used in refining processes is made safer with PTFE lined pipes.

Semiconductor Manufacturing

PTFE lined pipes are crucial for transporting ultra-pure chemicals required in semiconductor production.

Durability and Longevity

Thanks to their resistance to wear and corrosion, PTFE lined pipes are durable and have a long service life, which helps in reducing maintenance costs and downtime.

Safety

PTFE lined pipes enhance safety in industrial processes due to their exceptional resistance to aggressive chemicals and thermal stresses.
