Rated Pressure

(PSI)

• Constructed of ASTM A536 ductile iron

• MEGA-BOND® Restraint Coating System

For use on water or wastewater pipelines subject to hydrostatic pressure and tested in accordance with either AWWA C600 or ASTM D2774.

Sample Specication

Ductile iron pipe bell restraint shall consist of a wedge action restraint ring on the spigot joined to a split ductile iron ring behind the bell. The restraint ring shall have individually actuated wedges that increase their resistance to pull-out as pressure or external forces increase. The restraint ring and its wedging components shall be made of ductile iron conforming to ASTM A536. The wedges shall be heat treated to a minimum hardness of 370 BHN. Torque limiting twist off nuts shall be used to insure proper actuation of the restraining wedges. The split ring shall be made of ductile iron conforming to ASTM A536. The restraint devices shall be coated using MEGA-BOND®. (For complete specications on MEGA-BOND visit www.ebaa.com.) The connecting tie rods that join the two rings shall be made of low alloy steel that conforms to ANSI/AWWA C111/A21.11. The assembly shall have a rated pressure with a minimum two to one safety factor of 350 PSI in the sixteen inch size and below 250 PSI in the eighteen through thirty-six inch sizes. The product shall be the Series 1700 MEGALUG® restraint harness, manufactured by EBAA Iron, Inc., or approved equal.

Installation Instructions

4. Position the Series 1100 MEGALUG® restraint on the spigot such that the bolts are in alignment and the distance between the rings is suitable for the tie bolt length. Allow enough room on the tie bolt to fully engage the nuts with several threads showing.

5. Install the tie bolts in each available bolt hole for maximum distribution of operating forces. Place nuts on the end of the tie bolts. Allow room on the tie bolt to fully engage the nut with several threads

The Series 1700 is designed for restraining ductile iron pipe, conforming to ANSI/AWWA C151/A21.51 (all thickness classes) push-on pipe bells. It has a restraint ring on the spigot and a split ring behind the bell.

1. Install the split ring behind the bell in the direction indicated on the casting. Tighten the clamp bolts to 90 ft-lbs.

2. Place the Series 1100 MEGALUG® restraint gland on the spigot with the lip extension toward the bell.

3. Assemble the push-on joint per the pipe manufacturer’s instructions.

showing.

6. Pull the restraint ring away from the joint until the slack is removed from the tie bolts.

7. Tighten the torque limiting twist-off nuts in a clockwise direction (direction indicated by arrow on top of nut) until all wedges

are in rm contact with the pipe surface.

Continue tightening in an alternate manner until all of the nuts have been twisted off.

For Sizes 42 inch and 48 inch, two solid ring MEGALUGS are provided. One MEGALUG will be placed on the spigot with the lip extension toward the bell. The second will slide along the barrel of the second pipe and placed behind the bell (lip extension toward the bell). Then proceed with steps 3 - 8.

8. Tighten the tie bolt nuts until the ring

behind the bell is in rm contact with the

back of the bell. Do not tighten these bolts enough to force the spigot further into the bell.

9. If removal is necessary; use the ⅝ inch hex heads provided. If reassembly is required, assemble the product in the same manner as indicated in the previous steps and tighten the wedge bolts to 90 ft-lbs.
