We are offering Fluoropolymer Line Products that finds extensive usage in various industries such as chemical, petrochemical, pharmaceutical and food fertilizers. 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. We do PTFE lined 90° and 45° elbows, tees, reducers, reducing flanges, blind flanges, spacers dip pipes, spargers and thermocouple. These linings are widely used, where purity is critical, environmental pollution is to be avoided and pipe replacement is difficult. Our clients can select lining material as per the temperature requirements. In addition, we offer fully lined valve range in PFA/FEP/PVDF or PP, in order to provide complete solutions to CPI and related industries for their corrosion problems.
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: 250 ºC
- PVDF: 120 ºC
- FEP: 150 ºC
- PFA: 250 ºC
- ECTFE: 140 ºC
