Four-fluorinated molded pipe fittings include elbows, tees, crosses, and reducing tees. They are lined with materials of the same composition as steel-plastic composite pipes and come in corresponding sizes. When used with piping materials, they offer comparable corrosion resistance and are interchangeable and versatile. They are primarily used in the chemical industry, oil engineering, power engineering, mining industry, smelting industry, and more. All four-fluorinated molded pipe fittings are made with a solid steel shell, internally plastic injection-molded as a single piece, with no plastic welds. Performance: working temperature of medium: -25℃ to +105℃; working pressure of medium: positive 2.5MPa; negative 90KPa. Product features: non-toxic, resistant to temperature and low temperatures, resistant to vacuum and corrosion, anti-aging, shock-resistant, smooth surface with strong bonding. Good performance with organic solvents, suitable for conveying corrosive gases, liquids, and solid-liquid suspensions. This product is widely used in chemical, biological, power, smelting, food, environmental protection, and other fields, and is an excellent material for lining replacements for rubber, porcelain, fiberglass, stainless steel, and plastic plates within the temperature range of -20℃ to +105℃.
