QUICKLOCK forms a mechanical seal capable of repairing many pipe defects, complimenting the range of trenchless products already available to the local market, providing a rapid solution that requires little more setup than a routine CCTV inspection.
Already in widespread use throughout Europe and the USA, the QUICKLOCK system has benefitted from not only years of R&D, but years of refinement based on the feedback of industry and its installers.
Q. Is the QUICKLOCK system cost-effective?
A. A single QUICKLOCK seal installation works out at around AUD$2000, around 50% of the cost of a traditional open trench repair method. The cost effectiveness continues to improve if multiple seals are required at one access point, and as the preparation for installation is the same as a routine CCTV inspection, negotiating on-the-spot repair parameters and carrying spare seals to inspections can save a crew returning days later, reducing the inconvenience to property owners and stopping the impact of the defect.
Q. What is the life expectancy of a QUICKLOCK repair seal?
A. The QUICKLOCK system has a life expectancy of 50 years, and has been widely used throughout the European and US industries since its development in 1999.
Q. Who can install QUICKLOCK?
A. QUICKLOCK can only be installed by qualified, trained crews of technicians in order to meet the manufacturers stringent quality control requirements. QUICKLOCK Australia has ensured their local training course meets AQTF standards.
Q. What defects can the QUICKLOCK system repair?
A. The QUICKLOCK system – comprising of QUICKLOCK standard crimped and non-crimped seals, the QUICKLOCK BIG two-part rings & QUICKLOCK Liner End Sleeve – is capable of repairing common pipe defects such as: water infiltration/exfiltration; water infiltration at displaced joints; root intrusion/infiltration; closing dormant or unused inflows; overcoming joint displacement >15mm; cracked, fragmented or deformed pipes (longitudinal, cross-sectional and radial cracks).
QUICKLOCK can be used in horizontal or vertical sections of pipe; well piping (possible even under water); pressure piping possible up to 10 bar/145psi; and is also available as a perforated sleeve for drainage lines and filter piping rehabilitation;
Q. Is there an internal diameter range applicable for each nominal size QUICKLOCK Sleeve?
A. Yes, these applicable size ranges for each nominal sleeve size (DN150–1900) are outlined in the Technical Datasheet (see: Suitable for Pipes from/to)
Q. Why are there crimped & non-crimped versions of each QUICKLOCK seal?
A. When installed individually, a crimped sleeve is always used. When installed in a series, only the first sleeve in the direction of flow needs to be crimped, the rest can be non-crimped sleeves.
Q. What does the preparation for QUICKLOCK installation involve?
A. The pipeline to be rehabilitated must be cleaned and a CCTV inspection performed to determine the requirement for and exact location of seals. For this reason it is particularly useful to carry spare seals during routine CCTV inspections as repair is possible on the spot, eliminating the need to schedule future repairs & reducing the duration and effect of the pipe defect.
Q. How far from the access point of smaller pipes (DN 150-450) can QUICKLOCK be installed?
A. There are no limitations on distance from access to installation point.
Q. How quickly can the seals be installed?
A. The QUICKLOCK system has been designed to minimise preparation, and as the set up is the same for installing one or multiple seals, there is potential for up to 10–20 seals to be installed in a day.
Q. How does the system ensure rod & ratchet torque limits are not exceeded by the pneumatic packer during installation?
A. Maximum pressures are specified in the Users Manual (see: Control of the Maximum Set Pressure) and have been set through comprehensive training. As a secondary measure, a regulator can be set on the regulator.
Q. Are all metal components (including the lock) manufactured from Grade 316L Stainless Steel?
A. Yes, all coupling components, ratchet & sleeve are manufactured from Grade 316L Stainless Steel.
Q. What factors affect the longevity of use for Grade 316L stainless steel in a sewer gas environment?
A. The Stainless Steel has its limits in the salt content of the waste water. The resistance to various acids you can find in the appendix of the Users Manual (Corrosion of 316L at 80% Sulfuric acid = 0.1 grams per QM and year)
Q. How does the QUICKLOCK system perform in smaller pipes during high pressure jetting?
A. QUICKLOCK has passed rigorous testing for high pressure jetting resistance, the test results are outlined in the appendix.
Q. Does the QUICKLOCK system have any effect on ongoing pipe maintenance?
A. No, the QUICKLOCK sleeves incur a minimal cross-sectional area loss and the leading edge is crimped (flared) to ensure it won’t catch on cleaning equipment.
Q. What happens when complete rehabilitation of the pipeline becomes necessary in the future?
A. The QUICKLOCK system is compatible with all lining systems, in this instance, the liner can be installed right over the QUICKLOCK Sleeves. The QUICKLOCK Liner End Sleeve can then be used to cap off sections of lining to protect the ends from the pressure of jetting and other maintenance.
