FEATURED PRODUCTS
The EX-TEND® 200 joint is designed for pipelines that are subjected to expansion and contraction forces and is self restrained at full expansion.
The Force Balanced EX-TEND Expansion/Contraction Joint is designed to provide expansive or contractive movement to water pipelines subjected to linear movement. Unlike normal expansion joints, the Force Balanced EX-TEND does not generate an imparting thrust.
The Series 1900 is designed for restraining push-on bell and spigot AWWA C909 PVC Pipe. The harness consists of two split serrated restraints one on the spigot end and another behind the bell harnessed together by an array of thrust rods. The Restraint harness is rated to the full pressure of the pipe.
The Series 2100 MEGAFLANGE Restrained Flange Adapter is a field-adaptable wedge style restrained flanging system. It has a restraint ring and a gasket ring to give the maximum amount of flexibility during and after installation.
The Series 1100 MEGALUG® Mechanical Joint Restraints effectively and economically restrain Ductile Iron Pipe (DIP) to mechanical joints above or below ground, for practically any application including valves, hydrants, and pipe. For use on all classes of ductile iron pipe (PC350 through PC150 and CL56 through CL50) without damage to the pipe or cement linings. It can also be used on steel pipe and cast iron pipe when joining to mechanical appurtenances, see product brochure for more details on these pipes.
The MEGALUG Series 1100CH split restraint harness for couplings have a split design for ease of installation. It restrains both existing and new couplings on Ductile Iron Pipe.
FLEX-TEND Force Balanced Flexible Expansion Joints are designed to protect water pipeline systems from the stresses produced by ground motion either from seismic activity or gradual soil subsidence. The Force Balanced FLEX-TEND unlike conventional flexible/expansion joints does not generate an axial thrust that must be compensated for.
For use with gravity drain pipelines, the DWV FLEX-TEND is a flexible expansion joint can be used in drain, waste, and vent non-pressurized piping.
The Restraint Harness consists of one Series 1100 MEGALUG Restraint and one split bell back up ring. For use on water or wastewater pipelines subject to hydrostatic pressure and tested in accordance with either AWWA C600 or ASTM D2774.
The Series 1100TDM Tandem MEGALUG restrain ductile iron pipe to mechanical joint fittings, pipe and appurtenances that require high PSI ratings. It consists of one Series 1100 MEGALUG and one Series 1100 MEGALUG with the MJ lip removed as to sit properly behind the first.
The Series 3800 MEGA-COUPLING is a restrained coupling for similar and dissimilar pipe materials.
The Series 2000PV MEGALUG Mechanical Joint Restraint is the fastest and most economical method of restraining PVC pipe to mechanical joints. It can be used with C900, C905 or IPS OD PVC pipe. For sizes 42 through 48 inch See Series 2200
FLEX-TEND Flexible Expansion Joints are designed to protect water or wastewater pipeline systems from the stresses produced by ground motion or shear either from seismic activity or gradual soil subsidence.
The Series 2200 MEGALUG Mechanical Joint Restraint for use on Large Diameter (C905) AWWA PVC Pipe is a solid ring restraint for restraining PVC pipe to mechanical joint fittings and appurtenances.
The Series 1100HV is a restraint made for existing push-on joints on large diameter C900 PVC pipes. It is built from ASTM A536 ductile iron and has a MEGA-BOND® Restraint Coating System.
The MEGA-STOP® is a safe and economical “over-insertion” solution. With it, you can properly and quickly assemble pipe joints each and every time.

![What Are You Doing To My Pipe]( "What Are You Doing To My Pipe: Can PVC Pipe Be Loaded?")
The argument has been used that PVC pipe is delicate and can’t be subjected to any kind of loading. In EBAA's years of testing we have found that is not the case at all. PVC can take an extreme amount of strain.

![Ebaa Iron.jpg]( "Flexible Expansion Joints Provide Protection For Pipelines Subject To Subtle Or Sudden Movement")
Flex-Tend flexible expansion joints have a proven record of providing protection for pipelines subject to subtle or sudden movement. As with all products used in the water and wastewater industry, protection is optimized with the selection of the proper assembly incorporated into a sound design. This paper is intended to provide assistance in both of these areas.

![ConnectionsFT04]( "How Does The Force Balanced FLEX-TEND® Product Work?")
There are numerous configurations of flexible and expansion joints available to the design engineer. They include bellows joints, flexible hoses, bolted-mechanical couplings, and ball joints. In 1989 EBAA Iron, Inc. introduced the FLEX-TEND® joint (FT) flexible expansion joint product into the US market. Constructed of ductile iron, the product is comprised of two ball joints joined by an expansion joint. For the first time one product was available to protect pipelines and pipeline connections from differential movement resulting from seismic activity and soil expansion/contraction in areas of poor soil support, frost heave, and transitions from stable to unstable areas.

![ConnectionsPD02.jpg]( "Restrained Pipeline Design And Horizontal Bends")
In the last forty years, a quiet revolution has occurred in our industry. This revolution is the result of new generations of joint restraint products that make it possible to quickly and safely restrain fittings at bends, dead ends, tees, valves, and reducers without the need for concrete thrust blocks or tie rods. These joint restraint products turn the pipeline into its own thrust block. The key to utilizing these new products is the understanding and proper application of the pipeline restraint design theory.

![ConnectionsG07]( "Product Traceability")
The Merriam-Webster Online Dictionary defines traceability as “a: to follow the footprints, track, or trail of b: to follow or study out in detail or step by step… c: to discover by going backward over the evidence step by step … d: to discover signs, evidence, or remains of”. At EBAA Iron traceability allows you as the end user or us as the manufacturer to go backward into the production process and discover the signs that reveal the casting properties to the base level.
