TR-XTREME™

TR-XTREME PIPE IS DESIGNED FOR AREAS OF SEISMIC ACTIVITY AND UNSTABLE GROUND CONDITIONS. TR-XTREME joints provide 2.9" of extension capabilities to accommodate ground settlement and soil liquefaction during earthquakes while providing joint flexibility up to 4° for 6", 8", 12" and 3º for 16". The TR-XTREME joint is a patent pending joint that incorporates technology we’ve learned from over 40 years of designing restrained joints for the water works industry. The TR-XTREME joint is one of the strongest and most robustly designed restrained joints for water works and seismic markets. The TR-XTREME restrained joint utilizes the time proven and drop-tight TYTON® GASKET for a reliable drop tight seal. The features incorporated into the TR-XTREME restrained joint design help ensure that when disaster strikes, water will be available.

TR-XTREME pipe is available in nominal 18-foot lay lengths. The working pressure rating for the TR-XTREME pipe and joint restraint is 350 psi with a safety factor of two. Standard gaskets are SBR, styrene butadiene rubber, and special elastomers are also available (EPDM, NBR, CR and FKM).

For greater design and application adaptability for the most severe situations, U.S. Pipe offers the entire product range of TR FLEX® fittings, XTRA FLEX®

fittings and couplings, and TR-FLEX® telescoping sleeves that can be used in conjunction with TR-XTREME pipe. U.S. Pipe does not recommend TR FLEX GRIPPER® rings in earthquake applications due to the possibility of cyclic movement.

LININGS AND COATINGSPIPE: The standard lining and coating is Cement Mortar/Seal Coat with asphalt. A metallic zinc coating with asphalt or optional acrylic paint is offered as an option.

FITTINGS: The standard lining and coating is Cement Mortar/Seal Coat with asphalt. A metallic zinc rich paint coating with asphalt or optional acrylic paint is offered as an option.

PIPING SYSTEMS FOR UNSTABLE SOILSEXTENSIVE TESTINGTests of TR-XTREME™ joints were conducted in a 50º fault simulator split-basin at the Cornell Large-Scale Lifelines Testing Facility. A four-joint assembly was equally spaced about a 50º fault plane and the assembly was pressurized.

The resulting axial movement along the 50º fault plane was 12.2" with a maximum joint deflection measured at the joints closest to the fault of nearly 6°. The test demonstrates the joint's ability to sustain significant levels of combined axial pullout and deflection. The maximum stresses sustained by the pipeline, corresponding to the largest pipeline deformation, were well within the elastic range of pipeline behavior.

The test with TR-XTREME joints was able to accommodate significant fault movement through axial pullout and deflection of the joints. Fault rupture simulated in the large-scale test is also representative of the most severe ground deformation that occurs along the margins of liquefaction-induced lateral spreads and landslides.

The TR-XTREME pipe used in the large-scale split-basin test was able to accommodate 12.2 in. of axial extension. Such extension is large enough to accommodate over 99% of liquefaction-induced lateral ground strains measured by high-resolution LiDAR after each of four major earthquakes during the recent Canterbury Earthquake Sequence (CES) in Christchurch, NZ. These high-resolution LiDAR measurements for the first time provide a comprehensive basis for quantifying the ground strains caused by liquefaction on a regional basis. To put the CES ground strains in perspective, the levels of liquefaction-induced ground deformation measured in Christchurch exceed those documented in San Francisco during the 1989 Loma Prieta earthquake and in the San Fernando Valley during the 1994 Northridge earthquake. They are comparable to the levels of the most severe liquefaction-induced ground deformation documented for the 1906 San Francisco earthquake, which caused extensive damage to the San Francisco water distribution system.

The tests confirm that TR-XTREME joints are able to sustain, without leakage, large levels of ground deformation through axial displacement and joint deflection.

1. MULTI-BEAD For ease of field installation, TR-XTREME pipe can be ordered with multiple beads along a single pipe length. This feature

makes it easy to field-cut plain end transitions between TR-XTREME and TR FLEX fitting bells. The bead locations are set for the minimum lay length between two TR-XTREME bells. The bead gauge is used to mark the pipe for cutting. The bead gauge can be used to quickly mark and trim the TR-XTREME plain end for fitment to TR FLEX fitting bells. The distance between weld beads is designed so that two TR-XTREME x TR-XTREME plain ends can be cut. After the pipe is cut, the pipe must be beveled and all sharp edges should be rounded.

Bead sequence is repeated 4 times along pipe length

2. FIELD CUTTING AND WELDING Closure pieces may be fabricated on site using the TR-XTREME and TR FLEX FIELD WELD KITS in accordance with the

U.S. Pipe Field Cutting and Welding Procedure.

3. FACTORY-MADE CLOSURES For jobs that require engineered line drawings, closure pieces may be fabricated at the factory. U.S. Pipe can assist you

with customized pipeline layout drawings for your project.

DESIGN CONSIDERATIONS FOR UNSTABLE GROUND CONDITIONS• Pipe joints can withstand a high degree of joint compression. As the most important function of the joint is extension,

the TR-XTREME joints should be installed in a fully collapsed/inserted position.

• The entire system component approach would incorporate high deflection/high extension fittings (i.e., XTRA FLEX®, TR TELE FLEX®) at strategic locations.

• The normal installation would use thrust blocks at elbows (or other thrust locations) so long-term, planned joint extension is not consumed during line testing or normal pipeline operation.

• Polywrap should be used to encase high-deflection couplings and telescoping sleeves to ensure movement is not hampered by debris/dirt in the joints.

• Subaqueous lubricant should be used to install all joints. This lubricant is NSF approved and does not dry over time.

• If corrosive environments are suspected, zinc coating and/or V-BIO® polywrap are recommended.

When ordering XTRA FLEX Fittings, only the fitting configuration and line size need to be specified. For example, if an XTRA FLEX Fitting for a 6" line is to be ordered, specify a 6" XTRA FLEX Sleeve. The unit will be supplied with the proper size TR FLEX® Couplings and XTRA FLEX Reducers.

Equal opening tees and bends will be supplied in the same manner, with reducers in all fitting ends. In special conditions where reducers are not required in all ends or where tees other than equal opening are required, please contact your U.S. Pipe Sales Representative for the proper opening size.

The XTRA FLEX Reducers may be used to provide a reduced diameter, high deflection joint at most outlets of TR FLEX® Fittings. The table below shows the XTRA FLEX Reducers that are available.

XTRA FLEX Fittings will be shipped assembled with all components in place. To prevent loss of components in shipping and handling, each fittings assembly will be polyethylene encased. The assembled fittings should be inspected to make certain that all components are in place and then rewrapped in polyethylene to prevent soil from entering the joint opening, thereby reducing flexibility.

U.S. Pipe Telescoping Sleeves are Ductile Iron restrained joint fittings, which can be utilized to provide expansion and contraction capability in a pipeline. Telescoping sleeves are available with TR FLEX ends through 24" sizes. The restrained joints of the telescoping sleeves are suitable for 350 psi operating pressure in all sizes. Standard lining and coating is a petroleum asphaltic material.

The Telescoping Sleeves are capable of extending or contracting from approximately 10" to 24", depending upon the nominal diameter.

A special section of Ductile Iron pipe is used in each end of the telescoping sleeve to make up a telescoping sleeve unit. Each pipe spigot end socketing in the sleeve has a weld bead located at a greater distance away from the end of the pipe than the conventional weld bead of TR FLEX. The ends of the telescoping sleeve unit are provided with either TR FLEX socket(s) or with TR FLEX end(s) with weld beads as required.

NOTE: Conventional TR FLEX Pipe plain ends cannot be used in the telescoping sleeve. Special pipe ends are required, which have weld beads located farther from the end of the pipe than the standard bead on TR FLEX Pipe.

6" through 24" Telescoping Sleeves are one-piece units that contain the gasket seat and locking segment cavities.

TR FLEX® is a Registered Trademark of U.S. Pipe and Foundry Company.

THE TR TELE FLEX® COUPLING CONSISTS OF TWO XTRA FLEX® COUPLINGS AND

A TR FLEX® TELESCOPING SLEEVE. THESE UNITS ARE CONNECTED WITH TWO SHORT LENGTHS OF PIPE. The XTRA FLEX Couplings serve to give the unit its deflection and offset capabilities while the TR FLEX Telescoping Sleeve allows the unit to elongate and contract. The two lengths of pipe used in the standard unit are the shortest practical length. To acquire a greater offset capability, longer lengths of these connecting pipes can be provided.

The TR TELE FLEX Coupling consists of Ductile Iron components. With its deflection and extension capabilities, this assembly is well suited for use in areas where ground movement may result from unstable soil conditions or in earthquake-prone zones. Other typical uses of the TR TELE FLEX Coupling may include:

• Connecting of pipelines to pump stations

• Connecting of pipelines to water storage tanks

The TR TELE FLEX Coupling is shipped pre-assembled and palletized and protected with polyethylene encasement. The polyethylene encasement should be left on the assembly to provide protection of the moving parts.
