2.Product introduction

PTFE lined pipe is highly corrosion resistant. It's used to convey the most corrosive and toxic chemicals in
manufacturing plants, for the chemical, pharmaceutical and associated processing industries.
ptfe lined  cross are generally manufactured to ASME B16.5 class 150 dimensions. We can also offer fittings to DIN dimensions. Fixed flanges are used as a standard. Fixed and Loose flange connections are also availableon request.Instrument Tees to be used for temperature, pressure indicators And/or for samplings. The bodies are welded steel.

3.THE ADVANTAGES OF USING LINED PIPE SYSTEMS:

->The life of pipeline systems increases due to absence of corrosion
->PTFE lining safeguards and enhances better working conditions as leakage does not occur and subsequent
harmful gases and vapors do not evaporate in the atmosphere.
->The cost incurred in maintenance, repairing and time lost can be minimized.
->A wide variety of chemicals can be used through a PTFE lined system, making it more flexible and economical.
->Abrasion and wear resistant while maintaining nonstick and high purity characteristics.

4.Technic information
