Lined Pipe Components
Lined pipe components are pipeline parts with an inner protective layer made of corrosion-resistant materials such as PTFE, PFA or other plastics. These components are used in the chemical industry, pharmaceuticals and other sectors where aggressive media are transported. The lining protects the metallic base material from chemical attack and ensures the purity of the flowing media.
Lined pipe components are not uncoated standard pipes, not solid plastic pipes and not externally coated pipeline parts applied after manufacturing.

Lined Pipe Components: Frequently Asked Questions
What are lined pipe components used for?
Lined pipe components are primarily used in the chemical industry and pharmaceuticals where aggressive media must be transported. The internal protective layer shields the metallic base material from chemical attack while ensuring the purity of the flowing media. They are employed wherever both mechanical stability and highest chemical resistance are required.
Which materials are used for the lining?
Lined pipe components primarily use PTFE (polytetrafluoroethylene), PFA (perfluoroalkoxy), and other corrosion-resistant plastics. These materials are characterized by excellent chemical resistance to aggressive acids, alkalis, and solvents. The choice of lining material depends on specific requirements such as temperature, pressure, and media type.
What advantages do lined pipe components offer compared to full plastic solutions?
Lined pipe components combine the mechanical strength of metal pipes with the chemical resistance of plastic linings. They can withstand higher pressures and mechanical loads than pure plastic pipes while remaining resistant to aggressive media. This combination makes lined pipe components the ideal solution for demanding industrial applications.
In which industries are lined pipe components used?
Lined pipe components are mainly used in the chemical industry, petrochemicals, and pharmaceutical industry. Other application areas include the food industry, semiconductor manufacturing, and surface treatment, where high purity requirements and contact with aggressive media necessitate the use of such components. Wherever product purity and corrosion protection are critical, lined pipe components are preferred.
How does corrosion protection work in lined pipe components?
In lined pipe components, the internal plastic layer forms a continuous barrier between the transported medium and the metallic base material. This lining prevents direct contact of aggressive chemicals with the metal, thus protecting against chemical attack, corrosion, and material erosion. At the same time, the smooth surface of the lining ensures the purity of the flowing media and minimizes deposits.
