Fluorine lined globe valve
- Lining material Polyperfluoroethylene FEP (F46) Applicable medium: any organic solvent or reagent, dilute or concentrated inorganic acid, alkali, ketone, aromatic hydrocarbon, chlorinated hydrocarbon, etc. Operating temperature: -85~150 Features: Mechanical, electrical properties and chemical stability are basically the same as F4, but the outstanding advantages are high dynamic impact toughness, excellent weather resistance and radiation. Polytrifluoroethylene PCTEF (F3) Applicable medium: various organic solvents, inorganic corrosive liquids (oxidizing acids) Operating temperature: -195~120 Features: heat resistance, electrical properties and chemical stability are second only to F4, mechanical Strength, creep performance and hardness are better than F4 Polypropylene: RPP Applicable medium: aqueous solution of inorganic salts, inorganic acids, dilute or concentrated solutions of alkalis. Operating temperature: -14~80 Features: One of the lightest plastics, its yield, tensile and compressive strength, and hardness are better than low-pressure polyethylene, with outstanding rigidity, good heat resistance, easy to form, and cheap. After modification, it has dynamic impact, fluidity, and bending elasticity. Polyvinyl chloride: rigid) PVC Applicable medium: water resistance, concentrated alkali, non-oxidizing acid, chain hydrocarbon, oil and ozone, etc. Use temperature: 0-55 Features: high mechanical strength, excellent chemical stability and dielectric properties, good oil resistance and aging resistance, easy welding and bonding, low price. Polytetrachloroethylene PTFE (F4) Use medium: strong acid, strong alkali, strong oxidant, etc. Use temperature: -200~180 Features: Excellent chemical stability, high heat resistance, cold resistance, low friction coefficient, is an excellent self-lubricating material, but has low mechanical properties, poor fluidity, thermal expansion Big. Polyvinylidene chloride PVDF (F2) Use medium: resistant to most chemicals and solvents, use temperature: -70~100 Features: tensile strength and compressive strength are better than F4, bending resistance, weather resistance, radiation resistance. Light resistance and aging, etc., the biggest feature is good toughness and easy molding. Polyolefin: PO Applicable medium: various concentrations of acid and alkali salts and some organic solvents. Operating temperature: -58~80 Features: It is the most ideal anti-corrosion material in the world at present, and has been widely used in the lining of large-scale equipment and pipe fittings for rotational molding.
The manufacture marketing game of valve application is changing with each innovation, and businesses of all products need to be ready to pounce.
