Fluoropolymer lined products

The Lined Pipe System finds use in industries like Chemical, Petrochemical, Pharmaceutical, Food Fertilizers, etc… A majority of these industries make use of highly corrosive and hazardous acids and solvents in their processing applications. Being highly acidic and corrosive in nature, these chemicals tend to corrode and eat away the steel piping used as conveyors, rendering the system useless and unsafe for further use. Corrosion engineers are fast realising the long-term benefits of using high performance fluoropolymers to prevent corrosion of process piping systems.
We do PTFE lined 90° and 45° elbows, tees, reducers, reducing flanges, blind flanges, spacers dip pipes, spargers and thermocouple.

Selection of lining material as per your Temperature Requirement

In the chemical process industries, the temperature & method of the lining materials must be carefully selected. We recommend following virgin plastics resin as per their max temperature ratings :

  • PTFE : 250ºC
  • PTFE : 250ºC
  • PTFE : 250ºC
  • PTFE : 250ºC
  • PTFE : 250ºC
