Teflon lined pipe fittings are a steel PTFE type composite pipe fittings, which can resist strong acid and alkali. Pipe introduction: PTFE lined anti-corrosion pipe fittings after years of actual use, directly affect its service life and stable performance factors are temperature, pressure, media, etc., excellent materials and advanced manufacturing process is the quality assurance of PTFE lined products. Features 1. High temperature in strong corrosive media, can meet the use of temperature range -60 degrees ~ 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 with the operation of the situation caused by the local vacuum state 3. High pressure resistance in the use of temperature range, can withstand up to 3MPA of the use of pressure 4. Anti-permeation use of excellent PTFE resin, through the advanced lining process into a high density, sufficient thickness of PTFE lining layer, so that the product has superior anti-permeability 5. The overall moulding and sintering process of the lining solves the problem of hot and cold expansion of steel and fluorine, making it achieve synchronous expansion 6. The standardized dimensions are adopted, especially for the pipes and fittings used in chemical pipelines, which are highly interchangeable and provide great convenience for installation and spare parts. Anti-corrosion advantages: 1. High temperature resistance {use temperature 260 degrees. 2. Strong acid and alkali resistance (pH 1~14) 3. Excellent adhesion {negative pressure can reach 0.09MPa, vacuum effect. 4. Long service life {Under normal conditions it can be used for 8 to 10 years, and the warranty period is generally promised to be 1 year. 5. Strong resistance to penetration {hydrofluoric acid. Chlorine gas. Bromofluoric acid and other gases have good resistance to permeation Performance: Performance: medium work -100℃~-250℃ Medium working pressure: positive pressure: -2.5MPa, negative pressure resistance at room temperature 70KPa Corrosion resistance: steel polytetrafluoroethylene class composite pipe fittings, in addition to molten metal lithium, potassium, sodium, chlorine trifluoride, oxygen trifluoride at high temperature, high flow rate of liquid fluorine, it can resist almost all chemical media, including concentrated nitric acid and aqua regia corrosion, it can work at 230 ℃ - 250 ℃ temperature for a long time. Steel polyvinylidene fluoride class or other vinylidene fluoride class composite tube, to halogen, halogenated hydrocarbons, strong oxidants, boiling acid, alkali, a variety of organic solvents have good corrosion resistance, but not fuming sulphuric acid, concentrated hot sulphuric acid and nitric acid, 90 ℃ above the ketone, ester, amine and high temperature sulphonated agent corrosion. Advantages: High temperature resistance - use working temperature up to 250℃. Low temperature resistance - good mechanical toughness; even if the temperature drops to -196°C, the elongation can be maintained at 5%. Corrosion resistance - inert to most chemicals and solvents, resistant to strong acids and alkalis, water and various organic solvents. Weather resistant - has the best ageing life of any plastic. Highly lubricious - the lowest coefficient of friction of any solid material. Non-adhesive - has the lowest surface tension of any solid material and does not adhere to any substance. Non-toxic - non-toxic to organisms Product use: Steel lined PTFE pipe fittings applications: suitable for strongly corrosive gases and liquids at high temperatures, other types of steel-plastic composite pipes and metal pipes are not suitable for transporting media, steel PTFE composite. Combined pipe are applicable, steel polyvinylidene fluoride class composite pipe suitable for the transport of corrosive media at a working temperature of -40 ℃ ~ +150 ℃. Steel lined PTFE composite pipe fittings, using authentic tight lining process, resistant to negative pressure and vacuum, a molding without seams, flat and solid, no concave surface. The combination does not fall off. Widely used in electric power, chemical industry, petrochemical products, environmental protection and other industries.
