Ptfe lined pipeline is a steel polytetrafluoroethylene composite pipeline, which can withstand strong acid and alkali.
Pipeline introduction:
After years of actual use, the factors that directly affect its service life and performance stability are temperature, pressure, media, etc., materials and advanced manufacturing process methods are the quality assurance of PTFE lining products. Steel lined PTFE straight pipe commonly known as loose liner.
Features:
1: The use of high temperature in the strong corrosive medium conditions, can meet the use of temperature range -60 degrees to 200 degrees, in this temperature range can meet all chemical media
2: Vacuum resistance can be used under vacuum conditions, in chemical production, often due to cooling, longitudinal discharge, pump valve is not synchronized operation of the local vacuum state
Three: High pressure resistance in the temperature range of use, can withstand up to 3MPA of use pressure
Four: The selection of polytetrafluoroethylene resin, through the advanced lining process into a high-density, sufficient thickness of PTFE lining layer, so that the product has superior permeability resistance
Five: The integral molding sintering process lining solves the problem of steel fluorine hot and cold expansion, so that it can achieve synchronous expansion
Six: The use of standardized size preparation, especially the pipeline used in chemical pipelines, pipe fittings have strong interchangeability, providing great convenience for installation and spare parts
Anti-corrosion advantages:
1. High temperature resistance {High Operating temperature 260 degrees.
2. Strong acid and alkali resistance {pH value 1~14.
3. Excellent adhesion {negative pressure can reach 0.09MPa, vacuum effect.
4. Long service life {under normal conditions can be used for 8 to 10 years, the warranty period is generally promised to be 1 year.
5. Strong resistance to permeability {hydrofluoric acid. Chlorine, bromofluoric acid and other gases have good permeability resistance
Scope of use:
a. The operating temperature is -20~200℃
b. Use pressure ≤2.5Mpa
c. The negative pressure DN≤250mm is -0.09Mpa, and the negative pressure DN>250mm is -0.08Mpa
d. Can transport any concentration of strong acid, strong base, organic solvent, strong oxidant, toxic, volatile, flammable chemical media.
Features:
Performance: Medium operation -100℃~-250℃
Medium working pressure: positive pressure: -2.5MPa, negative pressure 70KPa at room temperature
Corrosion resistance: Steel polytetrafluoroethylene composite pipe, in addition to molten metal lithium, potassium, sodium, chlorine trifluoride, high temperature oxygen trifluoride, high flow rate of liquid fluorine, it can resist almost all chemical media, including concentrated nitric acid and aqua royal corrosion, it can work at 230℃-250℃ temperature for a long time. Steel polyvinylidene fluoride or other vinylidene fluoride composite pipes have good corrosion resistance to halogens, halogenated hydrocarbons, strong oxidants, boiling acids, alkalis, and a variety of organic solvents, but are not resistant to fuming sulfuric acid, concentrated hot sulfuric acid and nitric acid, ketones, esters, amines and high temperature sulfonators above 90℃.
Advantages:
High temperature resistance - operating temperature up to 250℃.
Low temperature resistance -- good mechanical toughness; Even if the temperature drops to -196 ° C, 5% elongation can be maintained.
Corrosion resistance - inert to most chemicals and solvents, resistant to strong acid and alkali, water and various organic solvents.
Weather resistant - has the best aging life of plastics.
High lubrication - low friction coefficient in solid materials.
Non-adhesion - is a small surface tension of solid materials, does not adhere to any substance.
Non-toxic - not toxic to organisms
Product use:
Steel lined polytetrafluoroethylene pipeline is suitable for strongly corrosive gases and liquids at high temperatures, other types of steel-plastic composite pipes and metal pipes are not suitable for conveying media, steel polytetrafluoroethylene. The combined pipe is applicable, and the steel polypartial fluorine composite pipe is suitable for conveying corrosive media with a working temperature of -40℃~+150℃.
Steel lined PTFE composite pipe, the use of authentic tight lining process, negative pressure and vacuum resistance, a forming without seams, smooth and firm, no concave. The bond does not fall off. Widely used in electric power, chemical, petrochemical products, environmental protection and other industries.
