ApplicationsTrelleborg Expansion Joints are used to create secureand better pipe systems. They help to compensatefor any bending, stretching and compression that mayarise. In addition, they reduce vibrations and noise.
They are used in industrial installations, offshore,dredging industry, cooling water systems for powerplants, in gas and drinking-water supply lines and incombination with condensors, in pumps, turbines,boilers and more.
ConstructionBy adapting the latest rubber and fabric technology,Trelleborg can provide the most effective solutionsto suit the required properties for any pipe systems.The expansion joints may be specially designed forpressures, temperatures, chemicals, lengths, diametersand shapes required by any applications.
The expansion joints may be manufactured indifferent shapes: round, square, rectangular, conical,with or without arches. In other cases with open orfilled arches, with or without flanges.
Although Trelleborg Expansion Joints count as asingle product, the potential variations are almostinfinite.
Consult Trelleborg and feel secureTrelleborg has more than 100 years of experience inmanufacturing rubber products, with a history ofstability and commitment to quality.
Continuous DevelopmentTrelleborg has invested heavily in R&D identifyingour customers needs. With our experienced technicalsales staff, chemists and engineers we are dedicated tofinding the most cost effective and appropriate solutions.This is achieved through continuous development ofnew materials, composites, design and manufacturingmethods.

ApplicationsTeguflex TU are recommended in small diameterpipes, pumps and equipments, because most con-nections in housing and industries services are oftenrequired in screwed connection rather than flangesfor small diameter installations.
Excellent for applications where large lateral orangular movements arise.
Typical applications could be pumps (suction anddischarge line), air-condition systems and irrigations.
DesignThe style TU screwed union expansion joints aredesigned to absorb pipe movements, stress, isolatevibrations, reducing system noise and protect againststart up and surge forces.
The Teguflex TU are designed in twin spherebecause its proven absorption and flexibility in alldirectional movements during operation.
By combination of spherical structure with superstability against internal pressure and strong specialreinforcement the Teguflex TU displays an outstandingpressure resistant of 30 bar bursting pressure or aboveat normal temperature.
The metal parts, made of malleable cast iron andhot dip galvanised, are furnished with BSP threadsas standard. Also available in stainless steel and/orNPT threaded unions.
