Fluorine ptfe lined steel pipes and fittings ASME

Fluorine ptfe lined steel pipes and fittings ASME 

With experience with paste-extruded since 1996.

PTFE and more than 1000 reference customers, we supply acomprehensive range of fluorine lined piping systems,

mainly for the transport of corrosive media.

The following pages provide information on available products,dimensions and design options, as well as the materials usedand permitted operating conditions.

This brochure deals exclusively with pipes & fittings up to adiameter of DN 600. Larger dimensions up to DN 3000 forcolumns and vessels are covered by a separate brochure.whichis available on request.

We offer our lined piping products in two different linerthickness classes.

**Standard:

Corrosion resistant and permeation reducing lining foraggressive media processed at moderate pressures andtemperatures. This product series meets the standards ofthe chemical industry for paste extruded PTFE linings.

**Heavy duty:

Suitable for long term operation with highly permeable mediaprocessed at high pressures and temperatures.

From our many years experience, we recommend the use ofstandardized pipe lengths. These reduce inventory costs andallow greater flexibility in assembly.

Our product range includes pipes of the following dimensions:Nominal diameters: from 1 to 24 inch.

Lengths:

arger diameters available upon requestfrom 100 mm up to 6100 mm (20 ft.)  depending on the nominal diameter.

PTFE is a paste-extruded PTFE material featuring exceptional thermal, chemical, mechanical, and electrical properties.

Outstanding Properties:

· Virtually universal chemical resistance and insolubility

· Low-temperature resistance down to -79°C

· High operating temperatures up to 260°C/500°F

· High flexural fatigue resistance; virtually no material fatigue

· Resistant to aging caused by heat or UV radiation

· Excellent electrical insulation properties

· Very high purity (free from migrating additives or monomers; non-toxic)

· Non-stick surface, low coefficient of friction/wear, self-cleaning

· Excellent dimensional stability—non-absorbent, no swelling

· Non-flammable

Field of use.  

Pressure load:

1to 6 inch - up to 40 bar [PN 40 )
