The low friction coefficient of PTFE assures that obstructions in spools (especially when carrying viscous liquids or slurries with a high solid percentage) are rare and in case they occur they can easily be dealt with.
Maximum working temperatures reach +230ºC.
Due to their reasonable cost PTFE linings are an interesting option to consider when thinking of using special material such as Hastelloy.
With a minimum thickness of 2mm minimum porosity is assured obtaining parts with a long work life. PTFE Linings can reach up to 7.5mm thickness for large dimension pipes or according to working conditions. Upon request we can supply all spools and accessories for vacuum working conditions.
Most standard sizes range from DN25 to DN300. Mounted flanges are usually ASME or ANSI B 16.5, but other standards can be applied as well.
