More than just a repair method for trenchless sewer rehabilitation
The UHRIG Quick-Lock system is much more than just a repair procedure. The patented Quick-Lock-System based on compression and the durable materials V4A stainless steel and EPDM has proven itself in the renovation of pipes over many years. In addition to the classic application as a repair method in sewer rehabilitation, the Quick-Lock system is also used for connecting pipe liner systems and for rehabilitating walkable sewers.
The Quick-Lock system has been successfully used for many years as a repair method for closed sewer rehabilitation. The basis of our development and production is quality and sustainability. Positive long-term experience from clients and Quick-Lock users worldwide also guarantees you pipe rehabilitation of the highest level with Quick-Lock. We now sell the patented Quick-Lock system worldwide.
The Quick-Lock system has established itself over many years in the renovation of drinking water and service water wells. Both vertical or horizontal installation are possible with the Quick-Lock cuff.
The new Quick-Lock Mini liner end cuff in the nominal widths DN 100, DN 125 and DN 150 with an overall length of 140 mm is a system for connecting house connection liners. The annular space between the liner and the old pipe is permanently sealed and the liner end is protected from the mechanical influences of high-pressure flush cleaning.
Our service providers are all specialist companies in the fields of sewer inspection, sewer rehabilitation or well rehabilitation. Our more than 20 years of experience in renovation with the Quick-Lock system forms the basis for training and technical support for our customers. Our partners are obliged to have their application technicians regularly trained.
The Quick-Lock cuff has a wide range of applications. Be it horizontal or vertical, above or below water level, it doesn’t matter to the Quick-Lock cuff. Due to the high quality and resistance of the materials used, Quick-Lock can not only be used in sewer rehabilitation, but also in the drinking water sector or for industrial applications.
Closed sewer rehabilitation
The Quick-Lock system can be successfully implemented for many types of damage:
In- and exfiltration
Closing blind inlets
If the damage pattern is longer than the sealing area of a single cuff, the Quick-Lock cuffs can be lined up together endlessly. The overlapping rubber seal ensure there are no leaks.
The materials used for the Quick-Lock cuffs, V4A stainless steel and EPDM, have a high resistance to corrosion and heat. This results in a wide range of possible applications in the area of industrial piping systems. The V4A stainless steel 1.4404 used can also be used to a limited extent with high pollutant concentrations of acids and alkalis. EPDM can be used at temperatures up to 120 degrees and resists high concentrations of acids and alkalis. Before using Quick-Lock in industrial applications, the resistance of the V4A stainless steel and the EPDM seal must be tested by means of a wastewater analysis.
Should a construction site is not accessible with the rehabilitation truck, e.g. on landfills, track drainage systems or tunnel drainage, Quick-Lock can be used on a mobile basis thanks to the transportable equipment.
Quick-Lock cuffs can be produced in perforated design for use in wells, horizontal wells and seepage pipes. The seepage capacity of the pipe system is also maintained and the statics are restored.
Pre-sealing and pre-stabilisation
In the case of extreme infiltration or static stabilisation, Quick-Lock can be used as a pre-seal before pipe lining measures. The Quick-Lock cuff is barely visible under the liner.
The Quick-Lock system can be used in pressure pipelines with an internal pressure of up to 10 bar.
The materials used here, V4A stainless steel and EPDM rubber, have proven themselves in pipeline construction for decades. The stainless steel material grade 1.4404 (316L) is almost indefinitely durable in wastewater.
The rubber seal made of EPDM corresponds to the current state of the art in sealing technology in pipeline construction with a very high life expectancy and very high levels of resistance.
For special applications in industry, refineries and saline waters, we will be pleased to supply you with stainless steel cuffs in special alloys on request. For this purpose we offer a rubber seal in NBR quality for applications with oils, greases & hydrocarbons. For drinking water applications we offer a drinking water seal with KTW approval.
The Quick-Lock cuffs are available in two configurations:
Variant 1: Overall length 400 mm, diameter DN 150-400, inner pipe pressure 10 bar, outer pipe pressure 1.5 bar
Variant 2: Overall length 500 mm, diameter DN 450-800, inner pipe pressure 10 bar, outer pipe pressure 1.5 bar
The Quick-Lock cuffs must be installed with the respective Quick-Lock offset packer; this is the only way to guarantee quality service. We can provide you with a large number of special measures for non-standardised internal pipe diameters. For applications in pressure pipe rehabilitation, we will be happy to advise you personally. In case of damage in drainage lines or filter piping, Quick-Lock is available as a perforated cuff.
Quality and proofs
In addition to a high-quality product, we place the highest value on professional application by our service providers. The repairs of wastewater pipes and sewers by means of inner cuffs are regulated in the new data sheet DWA M 143-5.
Quick-Lock has been approved by the German Institute for Building Technology (DIBt) since 2005. The approval regulates the quality assurance of the Quick-Lock system with all its components. We are externally monitored twice a year by the Darmstadt Materials Testing Institute.
The requirements for high-pressure flushing resistance of pipe and rehabilitation systems are regulated in DIN 19523. According to this standard, the Quick-Lock system fulfils the same requirements as a newly laid pipe system. 60 flushing sequences with a pressure of 110 bar at the nozzle and a subsequent leak test were the requirements that were successfully met.
By using the Quick-Lock system, the stability of the pipe is restored. Quick-Lock is the only partial rehabilitation system with a type statics for old pipe condition II, based on a hydrostatic water pressure of 5 m water column with double static safety.
