Product Specification

24inch Large Diameter Stainless Steel Flange Neoprene PTFE Lined Rubber Flexible Fittings

Product Introduction

      PTFE-lined joints are special structures lined with a layer of polytetrafluoroethylene (PTFE) material inside the rubber joints. PTFE is widely used in piping systems in chemical, pharmaceutical, food and other industries due to its excellent corrosion resistance, high temperature resistance, low coefficient of friction and non-adhesion. The rubber outer layer provides good elasticity and sealing, which can effectively absorb the stress caused by temperature changes, vibration or displacement of the pipe, and protect the piping system from damage.

Product Advantages

      1. Corrosion resistance: PTFE material can resist the erosion of most strong acids, strong alkalis and organic solvents, especially suitable for pipeline systems transporting corrosive media, effectively prolonging the service life of pipelines. 
      2. Flexibility and tightness: Although the lining material is hard PTFE, the rubber outer layer still maintains good flexibility and sealing, which can effectively absorb vibration and displacement in the pipeline system, reduce equipment damage and prevent leakage.
      3. Aging resistance and weather resistance: PTFE material has extremely strong weather resistance and anti-aging performance, and can maintain long-term stable use even in harsh environments.

How to choose PTFE lined rubber fittings

      1. Material selection
      When buying PTFE-lined fittings, the first thing you need to pay attention to is the quality of the material. The high-quality PTFE lining provides long-term corrosion protection for the joints and ensures durability in harsh environments. The quality of the rubber outer layer is also crucial, and it is necessary to choose a rubber material that is resistant to high temperature and wear to improve the service life of the overall joint.
      2. Pressure level and specifications
      When purchasing PTFE-lined fittings, it is necessary to select the appropriate fitting model according to the pressure requirements of the specific application scenario. In different industrial scenarios, the pressure on the pipeline varies greatly, and if the selected joint cannot withstand the corresponding pressure, it is easy to cause leakage or rupture. Therefore, it is important to confirm the pressure rating of the desired fitting before purchasing.
      3. Joint design and installation
      PTFE-lined fittings are usually available in different designs, such as single ball, double ball, multi-corrugated design, etc., and different designs are adapted to different applications. For example, the double-ball design of the joint can better compensate for the displacement of the pipe and is suitable for applications where a higher flexibility is required. When installing, it is necessary to ensure that the type of joint flange that matches the pipe and ensure the quality of the installation to avoid later problems caused by improper installation.
