Project Description

V-Flex Connector

In this Paragraph, I am going to tell you about V-Flex Connectors. First, they are designed to absorb thermal expansion or contraction or for seismic isolation of steel pipe or copper tube installations. Next, the braided metal hose elements incorporated into the design offer benefits that are not available in other products used for these applications. Finally, the unique  “V” configuration provides advantages over other metal hose connectors.

Thermal Expansion Applications

V-Flex Connectors are available as standard products for 1/2″ through 4″ nominal pipe size. They also have stainless steel braided hose and steel fittings – flanged, weld end, or grooved. Design conditions are 150 PSIG and 500ºF with a 2″, 3″ or 4″ travel choice.

Seismic Applications

V-Flex Connectors installed for seismic separation require an intermediate anchor on each side of the break that is no greater than the overall length of the V-Flex Connector plus four pipe diameters on each side. Furthermore, an alignment guide must be installed within four pipe diameters from the V-Flex if the separation is greater.

Standard Design

Moreover, alignment guides do not provide support for the weight of the system. Therefore, it may be necessary to install additional guides for long flexible runs to ensure alignment.

Guides, Supports, Anchors

V-Flex Connectors require anchors, guides, and supports. Refer to us for the guide and anchor requirements. In addition, it may be necessary to support the center elbow of the connector- refer to the illustrations of horizontal and vertical installations.

Flow Direction

The flow can be in either direction.

POST-INSTALLATION INSPECTION

  • Inspect the connector for damage with particular attention to the wire braid.
  • Is the connector at the correct location as specified?
  • Are the anchors and guides correctly installed? Are the guides free to move?
  • Confirm that the connector length is correct.
  • Confirm center elbow of the connector supported.
