Description
PTFE-lined composite pipe takes-common carbon steel pipe as substrate,lined with thermoplastic PTFE(Englishabbreviation is Teflon or [PTFE,F4])plastic with good chemical stability,and is made by specified technology.It hasboth mechanical properties of steelpipe,and corrosion resistance of highPTFE plastics.Slow scaling,noteasy togrow microorganisms.It's an ideal pipefor conveying media of strongacid,strong alkali,industrial salt andstrong corrosive gas,etc.Product Characteristics
Performance:-100ºC-+250ºC
Pressure
positive pressure :2.5Mpa,negative
pressure at normal temperature:70Kpa
Corrosion resistance
PTFE-lined composite pipe can resistalmost all chemical media(includingconcentrated nitric acid and aqua regia)in addition to molten metal lithium,potassium,sodium,chlorine trifluo-ride,OF3 under high temperature,liquidfluorine withhigh flow.It can work at thetemperature of 230ºC-250ºC for a longtime.PVDF or other composite steelpipes all have a good resistance tomany organic solvents like halogen,halogenated hydrocarbon,strong oxi-dant,boiling acid and alkali.But they are not resistant to fuming sulfuric acid,hotconcentrated sulfuric acid and nitricacid,over 90C ketone,ester,amineand sulfonation agent with high tem-perature.
Product Superiority
High Temperature Resistance-operatingtemperature is 250C
Low Temperature Fesistance--good me-chanical toughness.Even if the tempera-ture drops to -196C,it can also keep theelongation at 5%.
Corrosion Resistance--For the majority ofchemicals and solvents,it shows inertia.Resistance to strong acid,strong alkali,water and all kinds of organic solvents.
Weather Resistance--best aging life ofplastic;general service life is at least 10years.
High Lubricating Property--the lowestfriction coefficient in solid materials.
Inadhesion--the minimum surface ten-sion in solid materials,and does notadhere to any material
Nonhazardous--nobiological toxicity
