National Urban Renewal Mission

"Today, a third of our population lives in urban areas and keeping in mind the speed at which urbanisation is taking place, the day is not far off when over 50 percent of India's population will be residing in urban areas. We taught the world the basic concepts of urban planning. But today our cities are often unable to meet the basic needs of their residents on many counts." (Dr. Manmohan Singh, Honerable Prime Minister of India)

Demonstration of pipe and pipeline integrity by means of intelligent pigging systems

The service life of all man-made "technical  products" is limited. Piping and pipelines  are no exception. For technical  installations such as pipelines, availability  of which is critical for global economy,  strength analyses and service life  calculations must be prepared to furnish  evidence of pipeline integrity and  strength. The aim of these analyses and  calculations is, despite ongoing operational  loads, to prevent impermissible stresses  from acting on pressurized parts and  possibly resulting in critical conditions.  The increasing use of thin-walled pipes  made of high-strength steel further adds  to the necessity of inspecting pipe walls  for direct and indirect defects. Direct  defects are those which impact on pipeline  safety and integrity and are generally  detected by inspection pigs (pipeline inspection gauges).

Detection of coating defects in pipelines using in-line inspection tools

The following article investigates the current possibilities for the in-line inspection of pipeline coating. Due to its different accessibility internal coating should be distinguished from external coating. With the existing methods of in-line inspection some information on the condition of specific types of coating can be obtained. It is discussed which current inspection methods are able to deliver and how minor changes would improve the value of the information. For in-line inspection tools internal coating is easier to detect than external coating. Sample measurements are presented for testing of internal and external coating using intelligent ultrasonic inspection tools.

Trenchless Installation of Utility Tunnels

No-Dig Technology is in a constant process of gaining importance due to rising ecological and economical awareness. Microtunnelling technology for trenchless pipe installation in all geological and hydrological ground conditions is being more and more established on an international scale. Continuous research and development is necessary to face the increasing requirements of clients and contractors in international pipe jacking construction projects. Permanent improvements and further developments of the equipment are essential to make trenchless technology more and more competitive and cost-effective. Herrenknecht AG is proud to be front runner when it comes to new developments.

Cleaning of industrial pipes - Chemical pipe rehabilitation

In pipelines in industries formation of deposits occurs frequently. These deposits prevent the transport of substances and need to be removed on a regular basis to ensure smooth operation. Many a times, aggregates are installed such as heat exchangers, cooling tower or chill rolls, mastication rollers, injection moulding machines, bioreactors etc., and they have to function smoothly, because production depends directly on them. There are different processes for cleaning pipes, which include mechanical processes such as high-pressure cleaning, scrapper cleaning or milling, or alternatively chemical and chemo-mechanical processes respectively.

Humans, who can last a month without food, die after a week without water. And while we rely on water to sustain life, many are not aware of the vast network of reservoirs, plants and pipes required to treat, distribute, collect and clean water. Much of the nation's water infrastructure, built nearly a century ago for a smaller population, is aging and overburdened.

Prototype software helps predict failure in large-diameter water mains

Occurrences of failure in large-diameter water mains are few and far between, but when these buried pipes do fail, they fail in a big way. The consequences can be catastrophic, including prolonged service disruptions, flooding, major traffic and business disruptions, and contaminated water supplies. The cost of repair is also enormous.
