Teflon lining is a kind of steel polytetrafluoroethylene composite pipe, which can resist strong acid and alkali.After years of practical use of PTFE lined anti-corrosion pipes, the factors that directly affect its service life and stable performance are temperature, pressure, medium, etc. High-quality materials and advanced manufacturing methods are the quality of PTFE lined products. Guarantee. Steel-lined PTFE straight pipe is commonly known as loose-lined pipe.Its characteristics are as follows: 1. High operating temperature. Under the condition of strong corrosive medium, it can meet the operating temperature range of -60 degrees to 200 degrees. In this temperature range, it can meet all chemical media. 2. Vacuum resistance can be used under vacuum conditions, in chemical production Partial vacuum state is often caused by cooling, longitudinal discharge, and asynchronous operation of pump valves. , After the advanced lining process, it is processed into a high-density, sufficient thickness PTFE lining layer, so that the product has excellent impermeability. It adopts standardized size preparation, especially the pipes and fittings used in chemical pipelines are highly interchangeable, which provides great convenience for installation and spare parts.
