Product Information

|
|
Piping arrangements of all types, whether utility or process systems, are subject to vibration from pumps and equipment and stress created by thermal expansion or contraction. The resilience of elastomeric connectors can provide for controlled movement, while reducing noise and vibration. Elastoflex engineered flexible connectors install easily in a variety of piping systems, protecting the system from damage due to vibration and movement. Available in an array of materials and configurations, Elastoflex engineered flexible connectors are suited to almost any piping system and process fluid, and are available in two basic forms, expansion joints and pump connectors. Expansion joints are used primarily to allow for movement, but are effective in degrees at reducing vibration. Although pump connectors will not accommodate excessive piping movement, they provide excellent vibration damping and isolation. |

Series SJ-21
The SJ-21 Series is the industry standard spool-type expansion joint. Available in one arch (SJ-21), two arch (SJ-22), three arch (SJ-23) and four arch (SJ-24) styles, three pressure ratings and a wide variety of elastomers, this hand-built expansion joint can be adapted to the most unusual or difficult applications. Available in sizes up to 144 inches.
Series SJ-21 Expansion Joints can also be manufactured with filled arches to eliminate the settling of solids in the arch.

Series SJ-205
Manufactured with a streamlined, self-cleaning arch (see fig.1, next page), EVR's Series SJ-205 is designed to absorb vibration and eliminate buildup of suspended materials in the process flow. The SJ-205 expansion joint achieves considerable flexibility - rivalling standard multi-arch designs - with a single arch and the result is a light-weight joint with a very short face-to-face dimension. Available in sizes up to 144 inches.
The full faced rubber flange eliminates the need for gaskets, allowing for a fast, simple and completely leakproof installation. Available in three different pressure ratings, EVR's SJ-205 expansion joint can be fabricated in a variety of elastomers, allowing it to easily adapt to the requirements of any application.

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 version of the SJ-221 provides the same movement capabilities as a traditional double-arch design and the double-arch SJ-222 provides the same movement capabilities as a traditional quadruple-arch design. Available in sizes up to 144 inches.
This 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

Series CJ-31 Series EJ-41 Series OJ-61
For situations where piping diameters of different sizes must be connected, EVR's CJ-31 and EJ-41 tapered connectors are the answer. Manufactured to the same stringent standards as all of EVR's product lines, these units can be engineered for specific material situations and offer all of the advantages of EVR's other expansion joints.
EVR's OJ-61 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.

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.

Series TE-51
EVR's TE-51 Series Teflon-lined Expansion Joint enjoys all of the benefits and advantages of the Series SJ-21 combined with tough Teflon lining, adding durability for chemical/corrosive flows. The TE-51 is available with multiple arches for higher movement capabilities.
The elastomeric component of the TE-51 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 to withstand extreme temperature ranges, and functions well under high pressures or strong vacuums.

Series MJ-60 Series MJ-70 Series MJ-80 Series MJ-90
EVR's MJ Series consists of low cost, externally reinforced, molded expansion joints.
The MJ-60 is a low cost, double-width arch, molded butyl expansion joint with twice the movement capability of a standard expansion joint. The Series MJ-70 is a molded double-arch design, made of a precision elastomeric compound reinforced with multiple plies of nylon. The MJ-80 is the single-arch version of the MJ-70 and both styles feature a spherical arch shape that provides a smooth, low-turbulence flow which will easily handle process fluids with suspended solids. MJ-90 molded expansion joints are designed for smaller diameter piping systems and the union ends provide a simple means of servicing.
