Steel-lined PTFE pipes offer the mechanical strength of steel piping.

Four-fluorine-lined pipes are a type of pipeline that is resistant to strong acids and alkalis. Many people are not familiar with the rubber lining process of four-fluorine pipelines. In fact, there are four main processes, each with different methods. In the actual operation, it is necessary to master the methods and means for better operation.
The ETFE-lined pipe not only retains the mechanical strength of steel pipes but also boasts corrosion resistance, non-adhesive properties, and resistance to microbial growth, ensuring the purity of the transported medium. It is an excellent corrosion-resistant product that has replaced rubber, glass, and fiberglass linings. Its service life exceeds that of stainless steel pipes, making it an ideal corrosion-resistant pipeline for transporting acids, alkalis, salts, gases, and pulp. Yet, its price is just one-fourth of stainless steel pipes, standing out among various corrosion-resistant pipelines. All pipe fittings (elbows, tees, crosses, reducers, and flanges) are made of steel shells injection-molded with plastic linings.

The PTFE-lined steel pipe is based on ordinary carbon steel pipe, with a thermoplastic lined pipe for excellent chemical stability. After cold drawing and composite or rolling forming, it possesses the mechanical properties of steel pipes and the corrosion resistance of plastic pipes, is less prone to scaling, and not conducive to microbial growth. It is an ideal pipeline for conveying mediums such as acids, alkalis, salts, corrosive gases, and more. It can be used for food, pharmaceuticals, and drinking water. Key features of the PTFE-lined pipeline products: wide application, complete standard varieties; common production processes; reliable and convenient connection methods, and perfect and aesthetically pleasing external corrosion protection methods. Reasonably describe the wall thickness of the outer welded pipe; the inner wall thickness of the plastic pipe is reasonable, ensuring the pipe diameter; it has excellent corrosion resistance and energy-saving environmental protection properties.

The four-fluorine-lined pipes are made using the authentic dense-lining process, offering resistance to vacuum and negative pressure, with a one-time molding design for seamless, smooth, and sturdy construction without any concave surfaces. The key feature is that it will not fall off. They are widely used in industries such as power, chemicals, petrochemical products, and environmental protection.
