Quick-Lock remains key to pipe repair

Sewer Equipment Company (Aust), or SECA as it’s more commonly known, is Australia’s leading supplier of sewer and drain cleaning, testing, inspection and rehabilitation equipment.

For structural, trenchless pipe repair, the company offers the Quick-Lock solution.

The Quick-Lock system has revolutionised sewer rehabilitation through its wide range of applications and strong reliability.

Using heavy-gauge 316 stainless steel with infiltration abatement with an EPDM rubber gasket, the Quick-Lock system seals and stabilises damage completely by mechanical means, removing the need for chemicals and making it suitable for all pipe materials.

The patented locking system ensures that the sleeve stays permanently in position and, after rehabilitation, the sleeve has its own static capability and absorbs the natural tectonic movements of the pipe. 

The system can be used for standalone permanent point repair, or for pre-lining stabilisation works including high groundwater infiltration.

Quick-Lock sleeves restore a pipe’s structural integrity and seal out groundwater, and they are carefully designed to minimise diameter loss and outlast any other rehab.

For larger pipes, SECA offers the Quick-Lock BIG sleeve, which permanently seals leaking pipe joints, radial cracks, and longitudinal cracks in large pipes and manholes of DN800 and larger.

The BIG sleeves are 20 cm wide, and the system is made from V4A stainless steel of grade 1.4404 (AISI 316L) and an EPDM compression seal. 

These materials are permanently resistant in municipal wastewater systems, while their suitability must be ascertained for use in industrial or polluted wastewater.

Out in the field

SureSearch has more than 20 years of operating experience as a company, providing all aspects of utility investigative works, including location, non-destructive excavation, utility survey, mapping and clash detection, CCTV inspections, drain cleaning and pipe rehabilitation offers. 

SureSearch Sales and Development Manager Calyn Wilkinson said the company was relatively new to the pipe rehabilitation sector and felt using the Quick-Lock system was a good way of entering the market. 

“SureSearch has used the Quick-Lock system for both sewer and storm water rehabilitation,” he said. 

“It has been used for sealing joints, holes and also infiltration through cracks.

“Due to the fast installation time and no curing of material, it has a great advantage over the cured-in-place pipe (CIPP) method. 

“More installations can be achieved in a shift and if traffic control is required then this limits the amount of money spent on traffic control shifts.”

Quick-Lock end caps strengthen a CIPP liner at its most vulnerable points—the ends.

This mechanical solution prevents liner and host pipe infiltration or exfiltration for the lifetime of a close fit liner. 

It is particularly most effective on EX, spiral, and UV cured liners, and it is stronger and easier to install than other end caps, making them highly beneficial on any long-term watertight lining project.

Quick-Lock systems can be purchased from SECA’s warehouses or from SECA’s nationwide sales representatives.
