Long-term solutions for pipe rehabilitation

When it comes to pipe sanitation, municipalities can find it difficult to find equipment that is affordable, versatile and doesn’t require harsh chemicals. Since sewage, rainwater and drinking water pipes are valuable common goods, municipalities need long-term solutions.

Long-term pipe rehabilitation solutions must be low-maintenance and low-cost, offer applications for a variety of asset management applications, and not use hazardous chemicals that could leach into waterways.

Given that maintaining water infrastructure can cause significant disruption to communities, communities cannot afford to repair water systems frequently when long-term options are available.

Versatile trenchless technology

Quick-Lock is a trenchless pipe repair solution developed by German company UHRIG and available from SECA, a leading provider of cleaning, testing, inspection and rehabilitation equipment for pipes, sewers and drains. In 2023, Quick-Lock will celebrate 30 years in the industry.

Quick-Lock restores tubing, closes and seals unused feeders, reduces corrosion and leaks, eliminates cracks and fragmentation, and more. It implements pneumatically expanding rehabilitation sleeves and has been used successfully as a closed sewer rehabilitation process for many years.

These devices can be used for sewer, stormwater and potable water lines that run either horizontally or vertically, above or below the waterline.

Quick-Lock is also not restricted by weather conditions and can withstand hot summers or cold winters.

Whether it’s spot repair or liner end sealing, Quick-Lock has a variety of repair applications including:

∞ Cracks (longitudinal, radial and transverse)

∞ Leaks (groundwater infiltration and exfiltration)

∞ Root intrusions

∞ Joint displacements

∞ Pressure lines

∞ Infiltration and exfiltration

∞ CIPP end protection and sealing

∞ Closing/sealing unused side panels

∞ Improving the structural strength of pipes

∞ Root penetration

Fast installation for effective repairs

Quick-Lock can be installed within a tight time frame with minimal labor and overhead, and is easily transported to the point of repair using a CCTV crawler, push bar or robotic cutting system.

As a mechanical solution, it works without hazardous chemicals and requires minimal PPE for installation, making it a safer option for both the installation team and the community and local waterways.

Quick-Lock works by inflating the packer once in position, then the special closure, running on a double-sided raceway, locks the device and holds the sleeve firmly against the host pipe to seal the damage.

It shapes and forms part of the host pipe that permanently seals the space between the socket and the pipe to protect it from future infiltration – such as B. high-pressure cleaning – to protect. After rehabilitation, the sleeve is able to absorb the natural tectonic movements of the old pipe, as it creates its own static ability.

For liner end sealing, the end caps reinforce a cured-in-place pipe liner (CIPP) at its ends where it is most vulnerable. This is most effective on EX, spiral and UV cured liners as it is beneficial for long term waterproof liner projects.

In addition, if the damage is longer than a single socket, multiple sockets can be installed in sequence to form a continuous sealed pipe.

Avoid short-term fixes

Because installation requires no digging, using Quick-Lock allows for quick and safe repairs with minimal preparation; This helps councils avoid disruption in the community. But most importantly, this technology reduces the cost of on-going maintenance that is often required when implementing short-term solutions.

Quick-Lock is a combination of a stainless steel sleeve and an EPDM rubber sleeve that is chemically resistant to sewage, aromatic and chlorinated hydrocarbons, alkalis and dilute acids, meaning it eliminates the loss of ID and the need for other equipment in the future minimized .

With a lifespan of over 50 years, Quick-Lock is designed to outlast other rehabilitation methods and serve as a long-term investment and solution for municipalities and communities.
