Restrained Joints Clause Samples
The Restrained Joints clause defines the requirements and specifications for joints in piping or structural systems that are designed to prevent movement or separation under pressure or load. In practice, this clause outlines the types of joints that must be used, such as welded or mechanically restrained connections, and may specify testing or installation procedures to ensure their integrity. Its core function is to ensure the stability and safety of the system by preventing leaks, disconnections, or failures that could result from joint movement, thereby reducing the risk of damage or accidents.
Restrained Joints. Restrained joints shall be provided as shown on the Plans and where required for thrust restraint. Restrained joints shall not require field welding or grooves cut into the pipe barrel for restraint. The restraining joints for mechanical joint fittings shall conform to the requirements of ANSI/AWWA C111/A21.11 with assembly in conformance with AWWA C600 and manufacturer’s recommendations. Restrained joints for pipe shall be mechanical joints with ductile iron retainer or push-on type joints and shall have a minimum rated working pressure of 250 psi.
Restrained Joints. Restrained joints shall be provided as shown on the Plans and where required for thrust restraint. Restrained joints shall comply with the requirements set forth in the specifications for Ductile Iron Pipe and Fittings.
Restrained Joints. Joint restraints used with the installation of PVC or ductile iron pipe are considered subsidiary to the water line in which they are used and are not measured for separate payment.
Restrained Joints. Restrained joints are considered subsidiary to the water line in which they are used and are not measured for separate payment as outlined in the manufacturers’ catalogues and shall cover the cost for all materials, transportation, labor, equipment, excavation, sheeting, shoring, installation of the restraint device, polyethylene encasement, protection of existing utilities, backfilling, backfill material, disposal of unsuitable backfill materials, tamping, testing, densities, utility crossings, dewatering, trench stabilization, clean-up, restoration, and all work and materials necessary to install the restrained joint.
Restrained Joints a. Provide restrained joint pipe at fittings and valves as calculated by the Design Engineer and approved by the Town.. Restrained joints shall be Snap-Lok (▇▇▇▇▇▇▇ Pipe), Flex Ring and Lok-Ring (American), TR Flex (U.S. Pipe) or approved equal.
b. Restrained joint pipe and fittings shall meet all AWWA standards and other requirements as specified above for standard ductile iron pipe and fittings unless addressed herein.
c. Field made joints are allowable but should be avoided where possible. Careful planning to locate field cuts in standard pipe sections is preferred. For field made joints in restrained piping, use field weldments or an insert equal to TR Flex Gripper Rings or approved equal. Gasket type field made joints will not be allowed.
d. Restrained joint fittings shall be provided by the restrained joint pipe supplier where located within restrained joint pipe sections. Fittings shall be of the same model and type as the pipe supplied from the pipe manufacturer.
e. Restrained joint fittings may be push-on joint type.
f. Megalugs, Series 1100, as manufactured by EBAA Iron Sales or approved equal shall be allowable for restraint where approved by the Town.
g. The Contractor shall develop a field layout schedule and drawing for restrained joint pipe installations.
Restrained Joints. Joint restraints used with the installation of PVC or ductile iron pipe shall be included in the overall pipe measurements acceptably installed on the number of each size restraint device installed.
Restrained Joints. Restrained joints not be paid for separately but shall be included in the overall pipe measurements acceptably installed each fitting as denoted and shall cover the cost for all materials, transportation, labor, equipment, excavation, sheeting, shoring, installation of the restraint device, polyethylene encasement, protection of existing utilities, backfilling, backfill material, disposal of unsuitable backfill materials, clean fill, tamping, testing, densities, utility crossings, dewatering, trench stabilization, clean-up, restoration, and all work and materials necessary to install the restrained joint.
Restrained Joints. Restrained joints are considered incidental to the pipe installation and are not measured for separate payment and shall cover the cost for all materials, transportation, labor, equipment, excavation, sheeting, shoring, installation of the restraint device, polyethylene encasement, protection of existing utilities, backfilling, backfill material, disposal of unsuitable backfill materials, tamping, testing, densities, utility crossings, dewatering, trench stabilization, clean-up, restoration, and all work and materials necessary to install the restrained joint.
