You can also call Crane Resistoflex. According to their website, they are the largest supplier of PTFE-lined CS and SS piping in the world. They have plants in USA, Germany, and Singapore. Their website is as
Fpr plastic lined SS, size range is 1" nom. pipe size to 24" nom. pipe size. All material is flanged with Class 150 or 300. DIN, JIS, and other types of flanges are also available. For more questions, please contact me at mferg@resistoflex.com.
Remember when you are designing and specifying PTFE systems, you will be getting shop fabricated FLANGED spool pieces. This means the following:
- More flanged joints in the system ( and potential for leaks) This is a big consideration for toxic and/or expensive liquids.
- Virtually no "field adjustment" of pipe lengths.... this means your equipment must be on-target in the layout scheme and no last minute field layout changes. Insist on dimensioned spool piece drawings for all piping components.
A PTFE lined piping system must be designed, dimensioned and installed with great care so that there are no field surprises at final fitup time. (Its not like every other carbon steel system....)
