Trelleborg’s pipe seals operation has extended its Sewer-Lock™ range of integrated seals for PVC pipes with the launch of a new 450 millimeter diameter seal designed specifically to meet the needs of the Latin American sewer industry. The Forsheda 605 (F-605) Sewer-Lock composite seal significantly reduces scrap rates and, due to automatic installation, increases productivity for PVC pipe manufacturers and contractors.
Andreas Bichler, R&D Director at Trelleborg’s pipe seals operation, commented: “Rising population rates and rapid economic growth, especially across Latin America, has seen increased investment in water network infrastructure. We have developed the new Sewer-Lock seal in a 450 millimeter diameter to meet the specific wastewater pipe infrastructure needs of this thriving market. Not only does this latest product guarantee 100% leak-free performance but it also helps minimize operational costs by reducing scrap. This is because seal insertion is fully automatic and waste typically associated with manual insertion procedures is not produced.”
Manufactured by Trelleborg using two thermoplastic formulations, the new integrated sealing system has been developed specifically to fit plastic pipes for waste, storm water and cable protection applications. It is comprised of a flexible rubber element that creates an effective seal against the spigot and socket, and a second reinforcing polypropylene element that is bonded to the rubber and holds the seal firmly in place. This double bond improves the overall performance of the pipe as it enables the seal to become part of the socket forming tool and to adopt any pipe deformation caused by ovality. The seal cannot be displaced during transportation and installation and provides greater joint reliability due to joint tolerance reduction.
Designed to give low assembly forces so pipe jointing is easier, F-605 Sewer-Lock™ seals also meet or exceed current ISO standards for wastewater lines both for indoor and underground projects.
