Tetrafluorote liner is a specially designed pipeline connection, mainly used in highly corrosive, high-temperature or high-purity fluid delivery systems. The following is a detailed introduction to it:
1. The structure and composition matrix materials usually use carbon steel, stainless steel and other metals as shells to provide structural strength. Lining material: A layer of polytetrafluoroethylene (PTFE) is lining the inner wall of the pipeline, with a thickness of 2-3mm, covering all fluid contact surfaces to form an anti-corrosion barrier.
2. Material characteristics (PTFE advantages) Corrosion resistance: It can resist strong acids (such as sulfuric acid, hydrochloric acid), strong alkalis, organic solvents and other chemical media. Temperature resistance: a wide working temperature range (-196ºC to +260ºC), and can withstand higher temperatures in the short term. Non-stickness: smooth surface, prevent scaling, and reduce fluid resistance. High purity: suitable for industries such as food and pharmac
3. Application fieldsChemical industry: acid and alkali conveying, reactor pipeline systems. Pharmaceutical/Food: Sterile, contaminated fluid treatment. Plated/electronic: Corrosive chemical liquid transmission. Environmental Protection Project: Waste gas and wastewater treatment equipment.
4. Product Type Equi-diameter tee: The three ports have the same diameter. Separate diameter tee: The branch port is different from the main pipe diameter. Customized design: The angle can be customized according to pressure and flow requirements (such as 45°, 90° branches).
5. Core advantagesLong life: Compared with ordinary metal tees, corrosion resistance significantly extends service life. Cost-effective: Metal housing provides mechanical strength, and only lining uses PTFE, saving material costs. Easy maintenance: Reduce leakage and replacement frequency and reduce downtime losses.
6. Precautions for use Temperature pressure limit: Avoid exceeding the tolerance limit of PTFE (which may soften at high temperatures). Installation requirements: Special flange gaskets are required to prevent the lining from tearing; avoid violent installation or welding to damage the lining. Regular check: Pay attention to whether the lining layer falls off and bubbles, especially after violent temperature fluctuations.
7. Industry Standards Manufacturing usually follows GB/T 26120 (industrial plastic-lined steel pipes and fittings) ANSI/ASME B16.5 and other standards to ensure compliance with the dimensions and pressure levels.
Summary Lining tetrafluorote becomes an ideal choice for corrosive fluid systems by combining the mechanical properties of metals and the chemical inertia of PTFE, especially suitable for industrial scenarios that require long-term and stable operation. When selecting the model, medium characteristics, temperature and pressure parameters and installation environment must be comprehensively considered to maximize its performance advantages.
