Victaulic® C180230S34 230 Type 1 1-Segment C Class Non-Restrained Flexible Coupling, 18 in

Victaulic® bolted split-sleeve products (VBSP) style 230 carbon steel couplings (formerly Depend-O-Lok ExE) provide a non-restrained, flexible pipe joint that satisfies the requirements set forth by the AWWA C227 standard for bolted, split-sleeve restrained and non-restrained couplings for plain-end pipe. This style of coupling is typically used in buried or exposed pipe applications for flexible field joint connections where either joint restraint due to thrust is not a requirement or can be accommodated using an external joint harness system such as AWWA M11 restraint harnesses. External restraints must be installed to ensure the coupling does not exceed published values for allowable movement. Typical applications include water and wastewater pipelines, inlet and drainage piping and other piping applications that require a non-restrained flexible connection. The coupling provides ease of installation and comes standard with an epoxy coating for protection against corrosion. The use of a heat-shrink sleeve or tape system can be used with minimal effort due to the low profile configuration. The dual-arched mechanical coupling body houses O-ring gaskets that provide the radial seal around the circumference of the pipe, while a sealing plate provides for the axial seal across the coupling body and pipe joint. The style 230 coupling housing is designed to accommodate hoop stress to meet system pressure requirements while maintaining a leak-proof joint seal. The style 230 couplings also perform at negative pipe pressures up to full vacuum. The O-ring gasket is not pressure responsive and therefore does not require internal pipe pressure to assist with the seal. The arched cross-sectional shape of the coupling provides for a high section modulus to resist forces encountered during negative pressure (submerged) or vacuum service. Style 230 couplings are available in standard nominal sizes from 8 to 144 in/200 to 3600 mm with larger sizes available based on design and application requirements. The style 230 non-restrained coupling can accommodate operating pressures up to 400 psi/2750 kPa depending on the actual pipe diameter. For pressures and sizes not shown in the dimension and performance tables contact Victaulic® for information on our engineered products by visiting the Victaulic® web site. Style 230/230S couplings provide a flexible pipe connection and are not designed or intended to transfer significant shear, bending or axial loads across the pipe joint. Therefore a single coupling will not allow for differential settlement to occur at the joint. However a minimum of two flexible couplings designed to allow dynamic (in-service) deflection and installed in combination can be used to accommodate differential settlement at a pipe joint or between a pipeline and a structure. Style 230 couplings provide 1/2 in/15 mm of axial movement and are not designed for use as an expansion coupling. Victaulic® recommends style 233/233S couplings for this purpose as they are specifically designed to allow for dynamic deflection and provide thrust restraint at the joint. Refer to submittal publications 60.07 and 60.08 for product details and 26.20 for guidelines regarding the use of these couplings in differential settlement application. All flexible mechanical couplings should be properly supported to minimize or eliminate undesirable loads at the joint. Pipe support requirements are defined within the Victaulic® application guidelines document.
