The boom in the gas and oil business, sectors globally, has refocused attention on efforts to reduce corrosion on the surfaces of pipes and equipment used in the industrya new coating patterns based on nanotechnology that can be applied on the oil pipelines to combat corrosion.

Corrosion of pipelines is one of the major problems faced by engineers and technicians in the oil field. The annual cost of corrosion worldwide is over three per cent of the world's GDPand is around $2.2 trillion as per the National Association of Corrosion Engineers.

Florida-based Industrial Nano tech, which develops applications for sustainablenanotechnology coatings sold worldwide, says many manufacturers have had to concede energy loss in certain process-related equipment due to the inability to insulate with traditional coatings. Her company offers nano coatings as a way to insulate, and prevent corrosion and CUI, and do so with short-term payback and long-term performance.

Nanotechnology in Energy Saving

“Many times, equipment is left un insulated due to the limitations of the past,”“With new nanotechnology-based innovations, this is no longer the case. More of this wasted energy loss can be recaptured, and insulation now has the ability to prevent corrosion and CUI rather than causing it.”

Nansulate is a patented nanotechnology-based coating line from Industrial Nano tech that the company says has been providing significant energy savings and protecting equipment from corrosion for manufacturers for several years.The purpose of the application was to reduce heat energy loss of the petroleum along the pipeline. The Nansulate coating was applied to the exterior of the pipelines at an average of 350 microns dry film thickness. The pipelines’ surface temperature was measured to indicate reduction of heat loss. Prior to being coated, the average temperature of the pipeline exterior was 140°F; after coating, the average pipeline exterior temperature was 107.6°F. The coating also provided corrosion protection in the severe marine environment.

International conference held at Mumbai on September 2007 by NACE (National Association of Corrosion Engineers), focused on “Cost of Corrosion to the Nation”. Scientists from the U.S.A, Europe and India dealt on the subject at great length. Even a figure was arrived for India - world wide, U.S.A. A staggering numerical of Rs. 1,25,000 Crores was justified.

GDP % G.D.P Losses due to Corrosion

World Wide $ 30 Trillion Greater than 3% $ 930 bn
U.S.A $ 9 Trillion Greater than 3.3 $ 300 bn
INDIA $ 1 Trillion 3 - 4 % $ 40 bn
Rs 1,25,000 Crores

Even this figure is considered to be a modest one. More than 3,000 kms of coastline, higher temperature, humid climate justify for higher losses.30% of this loss could be saved if optimum corrosion management practices are employed. 63,000 km rail lines in India, pose a bigger problem for preventive maintenance. Majority of railway accidents are attributed to the corrosion. The cost of replacement of corrosion rails is given a modest figure of Rs. 440 Crores.using nanotechnology to fight corrosion of oil pipelines, which may costs millions of dollars to the large industry

Team Work - Meaning and Tips for better Team Work

A single brain is not always capable of making key decisions on its own. To come up with an efficient solution, an individual requires the help and advice of others. A team is established when individuals get together on a common platform with the common goal of completing a task. To guarantee optimum compatibility, team members should ideally come from similar backgrounds and have a single aim. To provide their best, the team members must complement each other and function as a single unit in tight cooperation. "There is no I in Team Work," as the saying goes, and each member must put the needs of his team first. Personal interests must take a second seat. Any team's performance is directly proportionate to the relationship between its members and their combined efforts. What is the definition of teamwork? Teamwork is defined as the sum of each team member's efforts toward the fulfilment of the team's goal. In other words, any team's backbone is its ability t

Scientists discover a new theory / The fundamental property of light – 150 years after Maxwell

Light plays a vital role in our everyday lives and technologies based on light are all around us. So we might expect that our understanding of light is pretty settled. But scientists have just uncovered a new fundamental property of light that gives new insight into the 150-year-old classical theory of electromagnetism and which could lead to applications manipulating light at the nanoscale. It is unusual for a pure-theory physics paper to make it into the journal Science. So when one does, it’s worth a closer look. In the new study, researchers bring together one of physics' most venerable set of equations – those of James Clerk’s Maxwell’s famous theory of light – with one of the hot topics in modern solid-state physics: the quantum spin Hall effect and topological insulators . To understand what the fuss is about, let’s first consider the behaviour of electrons in the quantum spin Hall effect. Electrons possess an intrinsic spin as if they were tiny spinning-tops,
