Product use of lined tetrafluoride pipes

Linining tetrafluoride pipe is a steel tetrafluoroethylene composite pipe, which can withstand strong acid and alkali.
Pipeline introduction:
After years of practical use of PTFE lining, the factors directly affecting its service life and performance stability are temperature, pressure, medium, materials and advanced manufacturing process are the quality assurance of PTFE lining products. Steel lined tetrafluorinated straight pipe is commonly known as loose lining pipe.
characteristic:
One: the use of temperature is high in the condition of strong corrosion media, can meet the use of temperature range-60 degrees ~200 degrees, in this temperature range can meet all chemical media
Two: vacuum resistance can be used under vacuum condition, in chemical production, often due to cooling, longitudinal discharge, pump valve is not synchronous operation and other circumstances of local vacuum state
Three: high pressure resistance in the temperature use range, can withstand up to 3 MPA use pressure
Four: antipermeability selection of PTFE resin, through the advanced lining process processing into high density, enough thickness of PTFE lining layer, so that the product has superior permeability resistance
Five: the integral molding sintering process lining, to solve the problem of steel, fluorine cold and heat expansion, so that it can reach synchronous expansion
Six: the use of standardized size preparation, especially the pipeline used in the chemical pipeline, pipe fittings have a strong interchangeability, for the installation, spare parts to provide great convenience
Anticorrosion advantages:
1. High temperature resistance {high use temperature of 260 degrees.
2. Strong acid and strong base tolerance {pH value between 1 and 14.
3. Excellent adhesion {negative pressure can reach 0.09MPa, vacuum extraction effect.
4. Long service life {under general conditions can be used for 8 to 10 years, the warranty period is generally promised for 1 year.
5. Strong permeability resistance {hydrofluoric acid. chlorine. Various gases such as bromofluoric acid have very good permeability resistance
range of application:
A. Use the temperature-20~200℃
B. Use a pressure of 2.5 Mpa
C. The allowable negative pressure DN 250mm is-0.09 Mpa, and DN> 250mm is-0.08 Mpa
D. It can transport any concentration of strong acid, strong alkali, organic solvent, strong oxidant, toxic, volatile, flammable chemical media.
function:
Performance: Media work-100℃ ~ -250℃
Medium working pressure: positive pressure: -2.5MPa, negative pressure resistance of 70 KPa at room temperature
Corrosion resistance: steel polytetrafoethylene composite pipe, in addition to molten metal lithium, potassium, sodium, chlorine trifluoride, trifluoride oxygen at high temperature, liquid fluorine at high flow rate, it can resist almost all chemical media, including concentrated nitric acid and water corrosion, it can work at 230℃ -250℃ temperature for a long time. Steel polyvinylidene fluoride or other vinylidene fluoride composite tubes have good corrosion resistance to halogen, halogenhydrocarbon, strong oxidant, boiling acid, alkali, a variety of organic solvents, but are not resistant to smoke sulfuric acid, concentrated thermal sulfuric acid and nitric acid, more than 90℃ of ketones, esters, amines and high temperature sulfation agent corrosion.
superiority:
High temperature resistance —— use working temperature up to 250℃.
The low temperature resistant —— has good mechanical toughness; maintaining an elongation rate of 5% even if the temperature drops to-196℃.
Corrosion-resistant —— for most chemicals and solvents, showing inert, strong resistance to strong acids and alkali, water and various organic solvents.
Climate resistance —— has the best aging life in plastic.
