Primus Line® – the prime solution for pipes

Primus Line® – the prime solution for pipes

Primus Line® – the prime solution for pipes

 

Primus Line® is a flexible sliplining solution for the trenchless rehabilitation of pressure pipes. The system consists of a flexible Kevlar® reinforced liner and specially developed end fittings. Primus Line® is not bonded to the host pipe and is self-supporting. An annulus remains between Primus Line® and the host pipe. Developed by experienced engineers, the system is suitable for different media as well as various application needs and has already proven itself in numerous projects.

Applications

Water

Water is a valuable resource as a basis of life, which requires sustainable use and our protection. Primus Line® guarantees a loss-free and secure conveyance of even the most-sensitive media, such as drinking water, contaminated or polluted liquids. Simultaneously, the composite pipe protects the old pipe from the inside against abrasive particles in the water and against corrosion.

Primus Line® is suitable for the transport of the following liquids in the water sector:

  • potable water
  • firefighting water
  • industrial water
  • sea water
  • waste water

Gas

Gaseous media represent a special challenge to trenchless pipe rehabilitation. However, an inner layer made of permeation-reducing plastics and the seamless production of up to 4,500 metres of the Primus Liner have made it possible for gas pipelines to also be renovated with Primus Line®. A monitoring pipe with a fitted valve which is affixed to the old pipeline allows the system-specific annular space to be monitored after the renovation work. The conveyed gas covers media from categories as natural gases, liquid gases, coke gases and mixed gases

Oil

The oil industry is facing new challenges as a result of damage to steel pipelines caused by internal corrosion. Possible leakages can cause significant environmental damage; they also mean increased costs or even loss of reputation for network operators. Primus Line® is suitable for the renovation of oil pipelines due to the medium-specific inner layer, and acts as a corrosion barrier between the transported fluid and the host pipe.  The conveyed fluid covers media from categories as crude oils, fuel oils, oil slag and other refined products.

Customised Products

The fields of application of Primus Line® are very diverse and will not be exhausted any time soon. The Primus Line® development team therefore works constantly in further developing the flexible relining system and creating customer-specific solutions. In close exchange with the customer, individual products are produced for special requirements.

Taking care of sensitive environments and protecting living environments

Small construction pits, short rehabilitation times and the low level of impact on the environment, make Primus Line® the ideal technology for the rehabilitation of defective lines in sensitive environments.
Regardless of whether it involves high traffic streets, nature reserves or sites difficult to access – it is just in these cases where Primus Line® is exactly the right solution. Without any large-scale impacts on the environment, pipelines can be renovated simply, rapidly and securely and put into operation again within the shortest time. As well as economic aspects, considerable advantages therefore arise for persons and nature:
  • No disturbance in the street, railway line or shipping traffic
  • Avoidance of traffic jams
  • Decrease of noise and emission pollution
  • Decrease of excavation work
  • Low level of impairment to existing building substance
  • Sustainability through the use of the existing infrastructure (old piping)
  • Low impact in landscapes and protection areas
  • Care of plants and species
The special suitability for sensitive environments results from the special installation method of Primus Line® and its simple handling. The installation is possible in the most confined spaces and with a low level of machine employment.

Pipeline Rehabilitation|

Pipeline Rehabilitation

We at Khuduyane Quigley believe in sourcing and implementing the latest technologies available worldwide when it comes to pipeline rehabilitation.

Pipeline rehabilitation can be defined as “a family of methods, materials, and equipment capable of being used for the installation of new or replacement or rehabilitation of existing underground infrastructure with minimal disruption to surface traffic, business, and other activities.”

The various applications used by KQ can be seen listed below.

CIPP is used to rehabilitate existing sewer pipelines by lining the walls of the existing pipe with an epoxy resin tube.
During the renovation process, the liner is soaked in resin and then inserted into the defective pipe using pressurised air or water. This completely lines the inside of the pipe and eliminates any existing or potential damage.

Curing creates a completely new, watertight pipe within the old one.

This rehabilitation application can be carried out quickly, permanently and cost-effectively.

BRAWOLINER® which is a “no dig” sewer rehabilitation system for repairing damaged drains and sewers without the need to carry out disruptive excavations.
brawoliner-2-2
The BRAWOLINER® process was developed specifically for the rehabilitation of pipes in diameters from dn 50 to dn 250 and offers many advantages compared to traditional remediation.

Advantages

  • Rapid rehabilitation without excavation, dirt and noise
  • Up to 50% cheaper than open construction
  • Suitable for almost all damage and all pipe materials
  • Durability of over 50 years

brawoliner-1-1

pri-1-3

Is an innovative technology for the trenchless rehabilitation of pressure pipelines for different media such as water, gas and oil. The process is based on a flexible high-pressure hose and a connecting technology, which has been developed specifically for this system.

Primus Line® is suitable for the transportation of various liquids in the field of water, and holds drinking water permits in several countries.

The extremely smooth inner coating, ideal flow characteristics and the optimized systems for high-, medium- and low-pressure requirements all make Primus Line® an economical choice for the rehabilitation of aging pipelines. Water authorities and network operators benefit from a sustainable and reliable operation and consistent revenue.

Quicklock Sewer Rehab Sleeve Restores Structural Strength, Seals Out Infiltration

Target Failing Pipes with a Stainless Rehab Sleeve that Installs in Minutes.
With more than 1,000,000 units installed worldwide, Quick-Lock provides structural trenchless pipe repair with heavy-gauge 316L stainless steel, plus infiltration abatement with an EPDM rubber gasket. It installs in minutes with two people and minimal overhead. Suitable for sanitary sewers, water lines and industrial pipes, Quick-Lock solves:
• Infiltration
• Longitudinal Cracks
• Circumferential Cracks
• Holes
• Offset Joints
• Abandoned Laterals
• Root Intrusion

Quick-Lock is positioned inside the host pipe on a wheeled flow-through packer pushed by any standard CCTV crawler. Once in position, air pressure supplied to the packer expands the sleeve against the pipe wall. Patented stainless gear ratchets within the sleeve sustain the outward pressure, which structurally reinforces failing regions of the host pipe, and also compresses the gasket for leak-proof service. Compared to open digging and CIPP point repairs, Quick-Lock eliminates:
• Digging and backhoes
• Resin
• Wet-out
• Pot life
• Cure
• Bypass pumping
• Wash-outs

Point Repair: For standalone point repair, or for pre-lining under high infiltration, Quick-Lock sleeves restore a pipe’s structural integrity and seal out groundwater. They minimize diameter loss and outlast any other rehab.
