• Series MJ-60

    A low cost, double-width arch, externally reinforced, moulded butyl expansion joint with twice the movement capability of standard expansion joints.

    This expansion joint is commonly used in pulp and paper applications, as well as water and waste treatment. Special, hand-made versions of this joint are available in different elastomers and multiple arch types for other applications.

  • Series MJ-70

    The MJ-70 double-arch expansion joint features a precision moulded elastomer compound reinforced with multiple plies of nylon. The shape of the arches provide a smooth, low turbulence flow which will handle process fluids with sus pended solids.

    Installation is easy due to the threaded Vanstone style rings, making them easy to align. Control units are also available.

  • Series MJ-80

    The MJ-80 single-arch expansion joint features a precision molded elastomer compound reinforced with multiple plies of nylon. The spherical shape of the arch provides a smooth, low turbulence flow which will handle process fluids with suspended solids.

    Installation is easy due to the threaded Vanstone-style rings, making them easy to align. Control units are also available.

  • Series MJ-90

    MJ-90 molded elastomer expansion joints are designed to handle vibration, misalignment and movement in smaller diameter piping systems. The union ends provide a simple means of disconnecting the piping to service equipment such as pumps. The maximum angular movement of this joint is 45°.

  • Series SJ-205

    Virtually all pulsating equipment, such as pumps and compressors, generate vibrations in both the flow and system piping. Vibration can increase loads on equipment, reduce efficiency, and increase maintenance costs. Continuous vibration leads to settling in the system which causes misalignment. Noise from vibration can also make the work environment intolerable.

    Manufactured with a streamlined, self-cleaning arch, EVR's SJ-205 is designed to absorb vibration and eliminate buildup of suspended materials in the system flow. The SJ-205 expansion joint achieves considerable flexibility - rivaling standard multi-arch designs - with a single arch. The result is a light-weight joint with a very short face-to-face dimension.

    The construction of the SJ-205 begins with a leak-proof inner sleeve, reinforced with multiple plies of polyester cord. The full faced rubber flange eliminates the need for gaskets, allowing for a fast, simple and completely leak proof installation. Available in three different pressure ratings, EVR's SJ-205 expansion joint can be fabricated from Neoprene, Nitrile, Hypalon, Viton or other suitable elastomers, allowing it to adapt easily to the requirements of any application.

  • Series SJ-21

    The SJ-21 is the industry standard spool-type expansion joint. The SJ-21 is available in configurations from zero to four arches - depending on movement requirements - and 3 standard pressure ratings in a variety of elastomers. This hand-built expansion joint can be adapted to the most unusual or difficult applications. Available options include filled arches to eliminate settling of solids in the arch, Teflon liners for severe chemical service, soft cuff ends for slip-on installation, and concentric or eccentric tapered ends for connecting different pipe sizes.

    Flange drilling is also available in all international standards or custom applications. For more information, contact EVR.

    Control unit assemblies are recommended for all applications. To ensure correct length, customer should provide width of mating flange or flange specification.

  • Series SJ-221

    The SJ-221 expansion joint features a unique arch design which provides greater movement capabilities without increasing face to face requirements. The single arch SJ-221 provides the same movement capabilities of a traditional double arch design and the double arch SJ-221 is equivalent of a quadruple arch product. The same design which provides increased movements also increases the flexibility of the joint, resulting in lower spring rates. This means less stress on adjacent piping system components.

    Flange drilling also available in all international standards or custom applications. For more information, contact EVR.

    Control unit assemblies are recommended for all applications. To ensure correct length, customer should provide width of mating flange or flange specification.

  • Series SJ-22

    With the same features as the SJ-21 style of expansion joint, the SJ-22 (2 arch), SJ-23 (3 arch) and SJ-24 (4 arch) styles offer greater movement absorption through their multiple arch design.

  • Series OJ

    EVR's OJ Series Slip-On expansion joint offers the perfect solution for new and existing installations. Its high degree of flexibility insulates and protects equipment from the damages of vibration and can easily accommodate normal misalignments.

    The OJ Series slip-on installation alleviates the need for, and cost of, pipe flanges by simply using pipe clamps to secure the joint to existing system pipes. EVR does not recommend use of the OJ Series in applications where pressure is greater than 50 psi.

  • Series TJ-95

    Offering an incredible degree of flexibility, EVR's TJ-95 expansion joint is ideal for ultra pure environments or systems with glass or Teflon-lined piping.

    Fabricated almost entirely from reinforced Teflon, the TJ-95 is non-conductive and well suited for low pressure, low temperature and corrosive chemical processes. The short face-to-face of the TJ-95 makes it suitable for even the most confining installations. Despite its light weight, it offers superb vibration and noise isolation for systems of all types.

    Available in two, three and five convolution designs for varying degrees of pipe movement.

    Data shown is for 3 arch style. Contact EVR for data on other styles.

  • Series TE-51

    Flow process machinery can generate considerable vibration that equates to excessive stress loads on adjacent equipment. In process systems with corrosive or caustic materials, conventional expansion joints materials may not be suitable. In a situation such as this EVR's Teflon-lined expansion joints, which are available with multiple arches for higher movement capabilities, is the answer.

    The TE-51 joint enjoys all of the benefits and advantages of the EVR Series SJ-21 expansion joint. The carcass of the TE-51 joint can be fabricated from any of the materials in EVR's comprehensive inventory to suit the requirements of the process system. The TE-51 can be engineered and manufactured to withstand extreme temperature ranges, and can function under high pressures or strong vacuums.

    The quality construction of the TE-51's leak proof Teflon sleeve, is banded to multiple layers of high strength bias-ply polyester cord, providing superior pressure ratings not available with conventional molded Teflon expansion joints.
