In piping systems, it is almost imperative to equip externally pressurized expansion joint, external pressure balanced expansion joint , to protect the pipes from damage caused by thermal expansion and to minimize vibrations. With the External Pressurized Expansion Joint EFR series, we would like to present to you a special line of thermal expansion couplings, which are the first choice for quality and many other advantages.

External Pressurized Expansion Joint EFR is a quality product line produced by E-Flex Vietnam on request and distributed nationwide. We have a mission to create true "Pipe Protector" products, protecting your pipes during use.

External Pressurized Expansion Joint EFR, in addition to the function of eliminating expansion and vibration, protects the pipeline, also provides high pressure and temperature resistance, and safety of fire. Due to the stainless steel material, it is suitable for installation and long-term use, with high corrosion resistance, reducing maintenance and replacement costs.

The product is highly regarded by the market for meeting most of the specifications and certification requirements needed for use in both residential piping systems and large industrial projects.

To choose the right externally pressurized expansion joint, external pressure balanced expansion joint for the specific use of each different application. First, customers must determine some basic specifications in order to choose the right stainless steel thermal expansion tube for the application.

It includes: expansion amplitude, connection type, solvent used, temperature used, delivery time & quality of packaging.
