High Pressure Pipe Rehab from Trelleborg


High Pressure Pipe Rehab from Trelleborg

Trelleborg’s pipe seals operation will launch two new trenchless technology sealing solutions for high pressure, potable water applications at this year’s No-Dig Show 2018 in Palm Springs, California.

Held from the 25-29th March, visitors to the No-Dig Show can learn more about the lead-free, NSF approved I-Lock-P™ Mechanical Seal and L-Lock-P™ Liner End Seal. The new seals will be showcased alongside Trelleborg’s ultra-flexible, main-to-house trenchless pipe relining solution – the DrainPlusLiner 2.0.

Tim Sparrow, Director of Sales, Americas for Trelleborg’s pipe seals operation, says: “Pipeline system owners are under increasing pressure to repair aging and failing pipelines, while minimizing the impact on the community, traffic and environment. Previously reserved for sewerage and wastewater systems, pipe relining is steadily High pressure pipe rehab from Trelleborg, No dig
on the rise in potable water applications. Due to the high pressure of the water travelling through the pipes, a more resilient solution is required as there is a risk of water getting between the liner and the pipe.

“Using our engineering expertise in polymer solutions for demanding environments, we have developed a new high performance mechanical seal and liner end seal which can easily and quickly be installed. Both products have been tested and certified lead-free and safe for potable water use. This enables pipeline owners to extend the service life of their existing water mains pipelines.

“No-Dig is the ideal platform to showcase the new seals and meet with industry representatives to get immediate feedback, ensuring our product development continues to meet customer needs.”

Specifically developed for high pressure potable water pipe relining, the two new seals provide a watertight seal for most types of pipe including steel, cast iron, concrete and plastic. Both are easily installed using a high force hydraulic expansion tool and are available in multiple diameters. The L-Lock-PTM is a rubber liner end seal with stainless steel expansion bands, designed to keep the liner firmly in place. The I-Lock-PTM is a mechanical seal applied without a liner to repair sections of cracked or damaged pipe.

Trelleborg will also be demonstrating its industry leading DrainPlusLiner 2.0. The highly versatile, all-encompassing liner can be used to repair every kind of condition or challenge faced when rehabilitating house connections and building pipes. Universally applicable for vertical and horizontal pipe lines, the liner allows for up to two nominal widths of variation in the internal diameter of the host pipe. It has an ultra-flexible silicone coating enabling it to travel through 90-degree bends and is suitable for steam-curing due to its heat resistant coating. It can easily transition from 4 to 6 inches, while still offering the required three-millimeter wall thickness at the expanded area
