Nov 23, 2004 The CSL Polyspray process was developed in England in 1984 for the coating of sewers in the nominal size range of DN 225 to DN 1000 [FI-Costa]. The spray lining machine consists of three main elements:
The two components of the polyurethane resin are pumped separately up to the mixing chamber and are there mixed intensively by an integrated plastics static mixer. Between the mixing … |

Mar 14, 2022 The damaged areas repaired by robot systems must be permanently tight, stable and resistant to the physical, chemical, biological and biochemical attacks to be expected in the respective section in accordance with the generally accepted rules of technology. In order to guarantee these requirements, in addition to professional planning, execution and implementation of the repair work using robots, appropriate quality assurance is also necessary [DWAM143-… |

Mar 14, 2022 Prior to the use of injection systems, the repair area must be milled to create a sufficient adhesive bond. The principle illustrations show the required milling patterns for a connection with and without CIPP-liner.

Jul 08, 2014 Article Lena Zemke Pilot project with CIPP technology of SEKISUI SPR in Shumen, Bulgaria - The challenges often involved in drinking water rehabilitation projects are the available time window, residual flow capacity after the rehabilitation, diameter and length to be renewed. Other factors are the capacity to negotiate bends and local contruction site conditions.

Nov 21, 2012 News Lena Zemke Often, in addition to cost considerations, site conditions can make open construction impossible. For the rehabilitation of the three 900 mm circulation lines at the Berliner Wasserbetriebe treatment plant in Berlin-Ruhleben, Germany, the constant hydraulic strain of the pipes prompted a decision for trenchless rehabilitation.

Mar 15, 2013 News Lena Zemke When the town of Kety in Poland needed to rehabilitate sections of two egg-profile sewer lines with large diameters in late summer 2012, SPR Europe was able to offer the town the perfect solution with its spiral-wound pipe method. With controlled live flow, it took 10 weeks to line the 425 metres of DN1000/1720 and 93 metres of DN1400/2100 concrete pipe with the SPR™ liner.

Mar 27, 2013 News Lena Zemke The Close-Fit method has existed for 20 years now as an alternative to other trenchless pipe rehabilitation technologies, such as CIPP or spiral-wound pipelining. With the pipe-in-pipe method, pressure pipes as well as gravity pipes of various diameters and lengths can be rehabilitated cost-efficiently and quickly, extending the service life of the pipes by at least 50 years.

Jun 05, 2013 News Mike Vellano Inland Pipe Rehabilitation (IPR), the nation’s largest privately owned trenchless infrastructure solutions provider, recently installed Cured-In-Place Pipe (CIPP) to renew more than 1600 ft. of water lines serving a North Dallas suburb water treatment plant. IPR installed its unique pressure pipe renewal system provided by RS Technik using Dow custom formulated resins.

Nov 30, 2023 Course Lining methods for the renovation of sewers and pipes represent the largest group of renovation methods. In the case of the lining processes self-supporting full linings of sewers are produced on the basis of prefabricated pipes, locally manufactured pipes and locally manufactured and hardening pipes. The subject of this course is "Lining with Cured-In-Place Pipes (CIPP)" and " Lining with Spirally-Wound Pipes".
In addition to the description of the procedure and process, the course deals in particular with the areas and limits of application, advantages and disadvantages as well as possible remediation errors and quality assurance options.
The course contains didactically prepared expert knowlege in 5 modules:
• Lining with Cured-In-Place Pipes (CIPP) - basics
• Lining with Cured-In-Place Pipes (CIPP) - Processes
• Lining with Cured-In-Place Pipes (CIPP) - Details on the Installation of UV Cured-In-Place Pipes
• Lining with Cured-In-Place Pipes (CIPP) - final work, acceptance, renovation defects
• Lining with Spirally-Wound Pipes with Stationary Winding Machine without Reinforcement made of Metal or Plastic
