  Introduction to PTFE:

  Because PTFE has high temperature resistance, corrosion resistance, non-stickiness, self-lubrication, excellent dielectric properties and very low friction coefficient. Generally used in pipelines, containers and pumps with high performance requirements. Fluorine lining is mainly used in strong corrosion conditions. PTFE is used to prevent medium from corroding rubber joints and pipes where rubber joints and strong corrosion contacts occur. PTFE is a synthetic fluorine-containing polymer, which has many applications due to its non-stickiness and resistance to certain chemicals.

  PTFE rubber joint has unique thermal stability:

  PTFE rubber expansion joints have unique thermal stability, non-sticky surfaces, very low friction coefficient and resistance to almost all corrosive fluids and chemical erosion forms. When other materials are not suitable, use PTFE lining expansion joint. They are designed for environmentally corrosive applications and are commonly used in chemical plants and water treatment plants.

  Use environment:

  PTFE expansion joints are widely used in paper mills, chemical factories and other pipeline applications for treating acid and highly corrosive chemicals.PTFE expansion joints we manufacture are used to transport chemicals, strong acids, corrosives or other harmful substances. Provide excellent tolerance for almost all chemicals.

  Rubber Joints of Different Material Used in Different Environment:

  Normal water, air conditioning water, temperature below 80 degrees: NR rubber joint;
  Weak acid and alkali, high 120 degrees: EPDM rubber joint;
  Hydraulic oil medium: NBR rubber joint;
  Acidic-alkali, high temperature below 140 degrees: KFM rubber joint
  Seawater: CR rubber joint.

PRODUCT ALBUM

INSTALLATION INSTRUCTIONS

1. Flexible rubber expansion joints shall not exceed the displacement limit during installation.
2. In the installation of bolts to be symmetrical, to gradually pressure and tighten, to prevent  partial  leakage.
3. When the rubber expansion joint is laid flat, suspended, and vertically installed, the actual working axial displacement pressure of the rubber joint should be less than the supporting force of the pipeline, otherwise the anti-lifting device should be installed to prevent the work from being pulled.
4. The installation location of the rubber joint should be kept away from the heat source and ozone area. It is strictly forbidden to irradiate with strong radiation, expose to the sun and use the medium that does not meet the requirements of this product.
5. When the rubber connector is transported, loaded, unloaded or installed, it is strictly forbidden to sharpen the surface sealing surface.
6. When installing DN200mm or above, please use butterfly valve special flange or small diameter flange for mating flange, so as to avoid flange pull-out, misalignment, sealing surface fracturing and water leakage after installation.
