Improving the performance of pipeline infrastructure demands continuous innovation.
Trelleborg delivered a conference paper on the evolution of elastomeric joints in plastic pipeline systems at Plastic Pipes XVIII conference, Germany. Presented by Product Manager, Julian West, the paper looked at how developments in joint design and materials innovation have had a positive impact on the performance and durability of pipeline infrastructure.
Pipe manufacturers, installation contractors and utility companies could learn how to achieve leak tightness from both infiltration and exfiltration in clean water and wastewater pipeline systems, as well as gain practical knowledge on reliable pipe jointing. Current material standards were also be covered in the session, as well as physical and chemical stress relaxation using ISO methodology, to predict the long-term durability of elastomeric joints.
Julian West, Product Manager Pipe Seals, said: “Improving the performance of pipeline infrastructure demands continuous innovation in both pipes and jointing systems, as well as their method of manufacture and installation. Advances in materials, coupled with improved seal and joint design, and low assembly techniques that eliminate site installation mistakes, play a key role in extending the service life of elastomeric joints. This in turn has a direct effect on reducing overall pipeline infrastructure downtime.”
Attendees could also learn about Trelleborg’s unique high-performance pipe seal solutions by visiting them on stand number 3. Equally effective under positive and negative pressure, the Trelleborg 601 Power-Lock sealing system uses an integrated design to eliminate the risk of seal displacement, while providing greater joint reliability and reduced risk of corrosion. Suitable for plastic pressure pipes, the seal is able to maintain a positive sealing force under vacuum to prevent sand or soil entering the joint.
Trelleborg also exhibited the 576 Anger-Lock with its unique locked-in sealing system for plastic pressure pipes, wastewater conduit and cast-iron fittings. This pipe seal cannot be displaced during transportation or installation and is also approved for contact with cold potable water.
Consisting of a combined lip and compression sealing system, the 582 Din-Lock seal meets or exceeds current European standards for wastewater lines, both indoor and underground, and gives low assembly forces to make pipe jointing easier. Leak-free and ozone resistant, this locked-in system delivers high performance sealing for DIN groove and plastic pipes and fittings, for wastewater and cable protection applications.
