FAQ

Q: What fluoropolymers do you use?
A:
AMETEK manufactures products primarily from FEP and PFA.  However, we will use whatever Fluoropolymer is appropriate for your application.

Q: What is the difference between the fluoropolymers?
A:
  All Fluoropolymer are chemically inert, thereby corrosion resistant and very pure.  The various types FEP, PFA, PVDF, PTFE, etc are designed for particular applications or conditions.  For example, FEP's are known for their toughness, PFA has better temperature properties.  The high purity grades are intended to have lower levels of extractables for applications where ppm and ppb count.

Q: What is the max temperature or pressure for my tubing?
A: The maximum temp and pressure are a function of each other along with the material properties and the tubing dimensions.  Please check the "Burst Pressure Calculator".

Q: What is the max temperature or pressure for my heat exchanger?
A: The maximum temperature and pressure are a function of each other.  Please refer to the data sheet, your completed sizing form or contact AMETEK to determine these conditions.

Q: How do you make Fluoropolymer heat exchangers?
A:
AMETEK makes Fluoropolymer heat exchangers using a proprietary fusion process developed over 30 years.  This fusion process creates a strong, solid tube sheet.

Q: Are fluoropolymers harmful?
A:
The available information says no.  Fluoropolymer resins can be processed at temperatures above 545F without hazard if proper ventilation is used.  If ventilation is not adequate and fumes of heated fluoropolymers resin are inhaled in sufficient quantities, influenza-like symptoms may follow.  The symptoms do not ordinarily occur until several hours after exposure and pass with 36 to 48 hours.  They have no lasting effects, are not cumulative and there are no records of serious injury.  If such symptoms do occur, they usually follow exposure to vapors evolved from the polymer at 545F or above or from smoking tobacco or cigarettes that have been in contact with it.  However, if at all concerned seek professional assistance.

Q: How do we dispose of a Fluoropolymer heat exchanger?
A:
  A clean (uncontaminated) unit may be disposed of in your normal trash service.  Units with residual process materials should be disposed according to local and federal regulation.

Q: How do we dispose of Fluoropolymer tubing?
A: Clean (uncontaminated) tubing may be disposed of in your normal trash service.  Tubing with residual process materials should be disposed according to local and federal regulation.

Q: What is the Honeycomb?
A:
The Honeycomb is the tube sheet on AMETEK heat exchangers.  It is called a Honeycomb because the shape of the constituent tubes.
