    Product Description

    Seismic V Connectors that brought forth by our well-distinguished organization are one of the most effective and ideal ways for compensating for thermal expansion or the unpredictable pipe actions encountered throughout the activity of seismic. These kinds of connectors are well engineered for absorbing movement in all ways. The exceptional "EFSVC" design places the flexible leg at the angle of 45o to the pipe run, even allowing up and down actions. Moreover, clients can get Seismic V Connectors in varied sizes, and finishes at negotiable prices.

    The standard position is with the V and 90 degree elbow hanging down.

    Horizontal and vertical mounting yields the same allowance for motion provided the 90 degree elbow is  supported properly to avoid sagging or torquing.

    “EFSVC” Connectors larger than 1-1/2” diameter must be supported if installed in any other position than the  standard position. Supporting cable or rod should be attached to an eyelet located at the bottom of the 90-degree elbow which can be provided by the factory. Flexible cable or pipe hanger rods can also be used. Position & Support Kanwal's Easyflex “EFSVC” Connector can be installed in a variety of positions.

    Installation

    In expansion compensation situations, the “EFSVC” Connector can be installed pre-compressed or pre-extended only if the full range of motion will be encountered in one direction. 

    If shipping bars are attached to the connector, they should not be removed until after installation. These bars are lightly tack welded to the loop to maintain the proper length until installation and will break-away in case of seismic activity. If the “EFSVC” Connector(s) are designed and installed to compensate strictly for expansion, then the shipping rods should be removed after installation. 

    For steam applications, a drain port and plug shall be specified and factory installed into the bottom of the 90 degree elbow to allow condensate to be drained. An alternative position for steam service is with the loop inverted, with the 90 degree elbow pointing upward. In this way, the “EFSVC” Connector will drain naturally into the surrounding piping. See the “Position & Support” section “Horizontal – V Straight Down”. 

    Advantages

    • Anchor forces are minimized because the pressure thrust is reacted by the wire braid.Anchor forces are minimized because of the inherent high flexibility of the metal hose.
    • The "V" configuration allows adjacent piping to be nested to save space.
    • V-Flex connectors can absorb in-plane extension and compression, or out of plane lateral offset.
    • Horizontal Run – “EFSVC” Connector Hanging Straight Down (as illustrated): 
    • Loop hangs straight down, without restriction, and free to flex. Support of the bottom elbow is not required. 
    • Pipe alignment guides are required to direct axial motion. 

    Horizontal Run – “EFSVC” Connector Straight Up: 

    Support must be provided at the 90 degree elbow to prevent the loop from leaning. Pipe hanger rod or cable must be loose enough to allow the 90 degree elbow to move up or down ¼” as the connector flexes. 

    Spring isolated rod is ideal for this application. 

    Horizontal Run – “EFSVC”Connector Horizontal:

    Support must be provided at the 90 degree elbow to prevent the flex hose from drooping or torquing the hose or pipe. Pipe hanger rod or cable must be loose enough to allow the 90 degree elbow to move horizontally back and forth ¼” as the connector flexes. Spring isolated rod is preferred for this application.

    Vertical Run – V Connector Horizontal:

    Support must be provided at the 90 degree elbow to prevent the flexible hose from drooping or torquing hose or pipe. Pipe hanger rod or cable must be loose enough to allow the 90 degree elbow to move horizontally back and forth ¼” as the connector flexes. Spring isolation rod is preferred for this application.
