India - Corrosion Control - NACE India Section News Letter - Invitation for Article Submission

Sub: NACE India Newsletter: Corrosion Combat

Dear Sir / Madam,


NACE International Gateway India Section publishes a quarterly News Letter “Corrosion Combat”. It carries report on the activities held during past quarters and gives information on the forth coming events. It also carries 3 - 4 technical articles. We are planning to bring next issue in the last week of April 2012.

I take this opportunity to request you to send an article on your experiences on corrosion related issues eg. causes of failure. The length of the article can be 4 - 5 A4 pages.

The paper should not published / submitted for publication elsewhere, including any journal or any conference. Trade / brand / patent name and text / tables / figures having “sales pitch” shall not be included in the text of the paperThese Newsletters send regularly to NACE International members, interested professionals working in the field of corrosion control and Heads of industries. Our next issue of the NEWS letter is on its way for printing.

We would, therefore, request you to send your article at the earliest and looking forward to your continued support.

Thanking you. Warm Regards

For NACE International Gateway India Section

India - Railway Bridges - The Spectacular Feat of Indian Engineering - Construction and Rehabilitation

Bridges were the most spectacular of railway engineering and architecture on Indian Railways a century ago and it continues to be at the close of this millennium. A bridge over river Hooghly was the most difficult engineering problem faced by railway men of that era.


Promoters of railways in India faced a major challenge in crossing the wide rivers, which changed their course dramatically with seasons. The climatic conditions vary considerably and so does the flow through the rivers.The volume of water register seasonal variations of magnitude unknown in other parts of the world. The varying character of the river-bed soil further aggravates the problem. Most rivers pass through alluvial soil devoid of rocks. To quote Charles Greaves, one of the early engineers visiting India in 1852: "The whole of the Bengal plain is nothing but a sea of mud, there is hardly a stone as big as coconut or a hill as high as a house.It is wonder having regard to the softness or looseness of the soil that Calcutta remained where it was." (Source: http://www.irsme.nic.in/mm.asp)

Quote from the publication http://www.irsme.nic.in/files/mmfiles/BRIDGES_RRB.pdf

James Meadows Rendel, the great consulting engineer, associated with railways in India from its very inception commented in 1854:

"There are engineering difficulties to contend with in India, which people at home cannot possibly conceive. Yet I am bound to say that the works executed by East Indian Railways (EIR) are equal to any of the kind done in this country; several large bridges have been built over river streams and rivers near Hooghly, and on exceedingly treacherous, sinking and shifting ground. Yet no failures have happened nor have any major accidents taken place, although since the planning of railway, heavier flood have risen in Bengal than have been witnessed since the days of Clive."

About 50% of these bridges are more than 100 years old. Though more than 1000 bridges are rebuilt/rehabilitated every year, the backlog is enormous. Old railway bridges are facing following types of problems:

• Aging and fatigue consideration

• Increased loading standards for axle load

• Increased longitudinal loads

• Rebuilding metre gauge bridges for broad gauge work.

• Replacement of Early Steel Girders provided prior to 1905.

• Corrosion problems in coastal areas.

US - Corrosion Research - Academia Industry Collaboration - Eastern Michigan University professor helps commercializing green protective

An Eastern Michigan University professor has partnered with a Michigan-based company to help commercialize “green” protective coating developed by his research team at the university.


Vijay Mannari, along with a group of students and other researchers at EMU’s Coatings Research Institute, located in the College of Technology, have focused their efforts on developing sustainable polymers and coatings that use renewable sources. One of the products Mannari’s team developed is a chromate-free, anti-corrosive pretreatment for metals, a protective coating that inhibits rust.

“The product is an innovative system based on Sol-Gel technology that is much safer than existing products, yet comparable in performance,” said Mannari.

India - Water Pipeline Leak - An unplugged water leak for 20 years in Nagpur - A strange practice of draining to keep the water pressure in rusted pipelines

NAGPUR: Even as water scarcity persists in parts of Nagpur city, there are at least a dozen places where water pipelines leak thousands of litres every day with no action from authorities. Surprisingly, in some areas, particularly in Shanti Nagar in Satranjipura zone, the leaks have been around for two decades without civic authorities taking any action.


On Tuesday, TOI spotted two places in this part of the city where thousands of litres of potable water is going down the drain due to leaks in major pipelines. Nearby residents said these leak have been around since two decades and despite many complaints water works department officials have not initiated measures to check the water wastage. With no effort to check water leakage, the people are left in the lurch, say residents.

"Most supply pipes in Nagpur are very old. Sealing leaks is a difficult proposition in such a network."

What Deputy engineer (water works), Satranjipura zone appeared to convey was that repairing these small leaks might raise water pressure in the rusted pipes and cause them to burst somewhere else. He also pointed out that they usually allowed a certain quantity of water to drain so that the pressure in pipes remains under control.

Turkey - Corrosion Research - A review of novel corrosion inhibitors from Pharmaceutical derivatives

Due to the toxicity of widely used corrosion inhibitors and the ever tightening environmental regulations surrounding their use and disposal, there is great interest in replacing harmful inhibitors with effective non-hazardous alternatives. Over the past two decades, extensive research and development have led to the discovery of new classes of corrosion inhibitors, and the importance on the use of several drugs as corrosion inhibitors has grown. This review presents most of the contributions made to the literature on the use of drugs as corrosion inhibitors of various metals in recent years.

IWCEM- International Workshops & Conferences on Engineering, Metallurgy & Corrosion in Military and Marine Applications have been in existence since 2008. The motto of IWCEM is 'Igniting Research for Application', and towards this endeavour the series of events have been conducted in 2008, 2010 and 2011 with the support of the Defence Institute of Advanced Technology, Pune, NACE Intl. India Section, Institute of Marine Engineers, India and the Sikkim Manipal University, Gangtok. The IWCEM activities are now being extended to support development, transfer and upgrading of applied technology.

In the year 2012, the IWCEM conference will be conducted in two phases, the National event in Pune, India from 19 – 21 May 2012, by Manipal University, Jaipur in association with the Institute of Marine Engineers, India, and the International event in Singapore, 14 – 16 Oct 2012, by National University of Singapore. This is expected to give a wider reach of interactions and technology exchange programs to the participants. The details of the events are regularly being updated on websites http://www.iwcem.org/ (National Event) and http://www.iwcem.com/ (International Event).

The IWCEM 2012 National Event would offer an interactive platform to exchange ideas, as well as to showcase the technical strength and present the product relevant to military and maritime operations. The event will also feature a session on technology upgrade requirements, with a focused approach to R&D projects.
