Machine parts, pipes, expansion joints etc. based on polyfluorethylene have all the advantages of the PTFE base
material. These products have an excellent resistance against:
• Acids
• Caustic soda
• Chlorides
• Sulfates
• Oxidants

190°C and +260°C.

INSTALLATION
PTFE lined tube parts are made of seamless PTFE linings which are fitted into (stainless) steel parts.
PTFE expansion joints have a PTFE bellow with turnable backing flanges. Both have a PTFE sealing area at the flange.
For safe and reliable operating the following instructions should be followed:
Receipt:
Keep the products in the original packing as long as possible. Unprotected storage outside is not allowed.
Distance bolts:
The expansion joints are equipped with distance bolts to avoid over stretching during installation and in operation.
These bolts should be adjusted to the maximum allowable length after the expansion joint is installed. The distance
bolts are not designed to take up the pressure reaction forces! (pressure x effective cross section) The pressure
reaction force should be controlled by suitable fix points.
Flange protection covers:
The PTFE sealing faces are covered by protection covers. These covers may only be removed prior to the installation.
I.e. after inspection the covers should be refitted.
Gaskets:
For installation of PTFE on PTFE there are no gaskets required. In case the connecting pipe material is different we
advise the use of a 5 mm thick PTFE gasket.
Welding:
Welding or burning near the PTFE is not allowed. (The PTFE can be damaged and toxic gasses can develop)
Pipe supports:
The pipe must be provided with sufficient supports and fix points.
Bolt torques:
For PN 10 flanges the following maximum torques should be applied. At room temperature these torques can be
increased by 50% The threads must be clean and well lubricated.

40 35 80 48 150 90 300 115 500 160
To avoid damage to the sealing the parts should only be dismantled below 40°C
Painting:
If the PTFE lined pipes are to be painted the ventilation holes may not be plugged by paint or insulation as this might
cause the lining to collapse. The vent holes also serve as early warning leakage indicators.

STANDARD RANGE
The PTFE / PFA lined piping consist out of several standard parts that are connected by flanges. Smaller pieces and
pieces with a complicated shape are executed with a PFA (injection molded) inlay. The larger diameters are executed
with a PTFE (paste extruded) inlay.
The standard dimensions are DN15 to DN 500 for DIN EN pipes and ½” to 20” for ANSI pipes.
Upon request we can supply larger dimensions or special shaped pipe parts.
PTFE LINED PIPE SPOOL
