PTFE Rubber Joints For Pipes Connecting Pipe Fittings Rubber Bellows Expansion

Product Specification

High-quality PTFE pipe rubber joints connecting pipe fittings flanges soft connections expanded rubber joints

Product Introduction

      The model of PTFE rubber joint is PTFE type, which is composed of two flanges and a rubber ball, and the assembly structure of the flexible rubber joint is the same, the only difference is that the PTFE rubber ball is added inside the rubber ball lined with PTFE joint, which has the characteristics of high temperature resistance, corrosion resistance, friction resistance, shock absorption, noise reduction, etc., and is one of the best corrosion resistant materials in the world today, and can work for a long time at a temperature of +250 °C-180 °C. It can be used in pipelines transporting a variety of different media.

Product structure composition

      The structural composition of PTFE-lined rubber joints mainly includes the following parts:
      Rubber body: This is the main part of the rubber joint, which is usually made of natural rubber, styrene-butadiene rubber, butyl rubber, nitrile rubber, EPDM rubber, neoprene, silicone rubber, fluorine rubber and other materials. These materials have different characteristics, such as heat resistance, acid resistance, alkali resistance, corrosion resistance, wear resistance, etc., to adapt to different media and use environments.
      Lined PTFE: The lined PTFE layer is made of polytetrafluoroethylene (PTFE) material, which has excellent corrosion resistance, high temperature resistance, and low coefficient of friction. This layer is in direct contact with the medium, which can withstand the erosion of various strong acids, strong alkalis, solvents and other chemicals, and protect the rubber body from corrosion.
      Limit rod: The limit rod is used to prevent the joint from falling out when subjected to excessive tension and ensure the stability and safety of the joint.
      Flange: A flange is a connecting part of a rubber joint, usually made of carbon steel or stainless steel. The design and material of the flange directly affect the installation quality and sealing performance of the joint.

Maintenance and maintenance of the product

      1. Check the joint status regularly
      Even though the PTFE-lined fittings have strong corrosion resistance, they may still be worn out due to changes in the external environment or media erosion during long-term operation. Regularly check whether the rubber layer on the surface of the joint is cracked, aging, and whether there is leakage at the joint flange connection.
      2. Avoid overload operation
      When using PTFE-lined fittings, avoid operating at pressures or temperatures above their rated pressures or temperatures. Overload operation can accelerate the aging of joints and may even lead to accidental rupture, which can lead to major equipment damage and safety hazards.
      3. Cleaning and maintenance
      During the process of media transportation, try to keep the joints clean, and regularly clean the pipes and joints to prevent fouling or corrosion. Avoid contact with sharp objects or chemicals that directly corrode the surface of the joint, so as not to affect its service life.

Precautions when using the product

      1. When installing, make sure that the flange connection bolts of the piping system are tightened to avoid additional stress on the joints.
      2. During use, the sealing performance of the joint should be checked regularly, and if leakage is found, it should be dealt with in time.
      3. For conveying high-temperature, high-pressure, and corrosive media, suitable PTFE-lined joints should be selected, and operated in strict accordance with the requirements of use.
      4. When installing and dismantling, avoid excessive force or use of sharp tools to avoid damage to the joint lining material.
      5. During storage and transportation, direct sunlight and humid environment should be avoided so as not to affect the performance and service life of the joint.
