1.1 This specification covers the minimum performance and material requirements for a three piece tee connector for connection between plastic pipe and insitu pipes, manholes and wastewater structures in sanitary and storm sewer applications. 1.1.1 The three piece seal system consists of a 4 through 30-in. PVC (polyvinyl chloride) hub pipe, an elastomeric seal (gasket) and a mechanical band (Fig. 1). The system is installed in either a bored or cast hole opening in the host pipe or structure to a specific dimension that corresponds to the combined diameter of the PVC pipe outside diameter/tolerance and the elastomeric seal thickness. FIG. 1 Three-Piece Sealing System (Connector) 1.2 These tee connectors are designed to provide a non-pressure (gravity flow) watertight connection between the incoming pipe and an insitu pipe or manhole/structure to the limits defined in this standard. Note 1: Connections covered by this specification are adequate
for laboratory hydrostatic pressures up to 13 psi (30 ft of head)
without leakage when tested in accordance with the provisions of
this standard. Infiltration or exfiltration quantities for an
installed system are dependent upon many factors other than the
connections between incoming pipe and the insitu pipe or manhole
structure, and allowable quantities may need to be covered by other
specifications and suitable testing of the installed pipeline and
system. Where connections are made to concrete manhole sections
refer to Specification C923.
Note 2: These connectors are not resilient connectors, and as
such, allow for only a limited amount of lateral movement due to
the tight compression seal between the PVC hub and insitu
pipe/structure. Since these connectors are not rigid fittings, a
significant amount of axial movement can be accommodated, but the
degree of intrusion into the host pipe/structure must be regulated
to minimize the impact on flow characteristics or hydraulic design
conditions.
1.3 The following precautionary caveat pertains only to the test methods portion, Section 7, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For a specific precaution statement, see Section 7. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
