Pipe Rehabilitation

It is up to two decades, KWH pipe has contributed in the development of pipe rehab techniques. To recline application, a number of solutions have been provided by KWH Pipe. At first, the relining of leaking concrete pipes was the main part of the rehab business. These days, rehab works cover continuous pipes, Weholite pipes, segmented pipes and ViPLiner pipes. Furthermore, working processes as well as raw materials have even undergone drastic changes like trenchless relining making use of VipLiner short modules, renovation of manholes, pressure water pipes and gravity sewers. Long length relining making use of Weholite pipes, manholes to meet the requirements of the consumers and PE-pressure pipes

Weholite and structured wall pipe are necessary and the best solution for rehabilitation of huge road culverts, big pipes. Considering the size, pipes are joined by sockets or threaded joint or welding. VipLiner rehab technique is a sliplining system where you insert a string of discrete into an existing carrier pipe. Continuous sliplining technique means a continuous pipe is fit into an existing defective pipe. Relining pile is welded in strings prior to insertion. It is has been launched from an entry shaft excavated for the rehab project. Generally, WehoPipe is used with diameters of Ø20 -Ø1600 mm. Such technique needs winches and pulleys to pull or push the new pipe through the old one. Pipes may be used for gas pipes, water mains and sewers. There is a leading provider of CIPP, cured-in place pipe and a few technologies and services for the rehab of pipeline systems. The business of this leading provider also consists of drinking water and energy and mining pipeline rehab, sewer, protection. Cost-efficient solutions have been provided by the company for remediating environmental, operation, health and regulatory issues that are resulting from faulty pipeline and aging.

A leading provider of CIPP, Insituform specializes in trenchless rehab system for potable drinking, pressure pipes and distribution mains. Mining capabilities and comprehensive energy of Insituform offer products as well as solutions for the requirements of pipelines from lining products to cathodic protection to full rehab if essential. The mining section and Energy of Insitufom includes three divisions such as United Pipeline Systems, Corrpro Companies, Inc and The Bayou Companies.

United Pipeline Systems provides premiere HDPE solutions for both oil and gas pipeline rehab including the Tite Liner system. Corrpro Companies, Inc is a foremost provider of coatings, corrosion control engineering services, equipment for infrastructure, cathodic protection systems, and environmental energy markets across the world. The Bayou Companies offer best quality fusion bony epoxy coating, prefabricated products and deepwater coating to the gas industry.

Trenchless pipe rehab is the method of trenchless pipe replacement with the help of renewal method that includes dynamic pipe bursting, pipe eating bases on microtuneling and pipe extraction method with grundoburst. The bursting machine in dynamic pipe bursting method is pulled by a winch through old pipe that needs to be renewed. The old pipe is totally destroyed in this process by dynamic impact energy as well as fractured particles get pushed into surrounding soil. The new line gets pulled in at the similar time in the similar width.

Pipe eating technique is the technique of replacement that is mainly based on micro tunneling where defective pipe dig up together with the surrounding ground since it is for the new installation. Making use of hydraulic jacks placed in drive shaft, pipe eating shield is pushed with the existing pipeline. Replacement pipes get connected to the back of tunneling shield. Once the drive length is completed then the pipe eating shield is recovered at reception shaft, putting a new pipeline in place of faulty pipe.

Damaged gas and water lines are replaced by new pipes by making use of pipe extraction method with grundoburst. Pipe splitting method gives solution to the issue of lead pipes replaced by plastic pipes for supplying potable water. Such method was originally development by the water supply company of Berlin for performing trenchless lead pipe replacement.
