  • What makes high-risk pipelines deteriorate to a state of failure?

    According to AWWA's 2016 Benchmarking Survey, the average water and wastewater utility has seven breaks per 100 miles of piping every year. Tip-top systems experience just four breaks in that distance, while those at the bottom have 18. While it’s interesting to note the difference in break rates, it’s unfair ...

  • On the Ground with Diesel Corrosion - Case Study

    When the EPA revealed the results of its study in July on the increasing presence of substantial corrosion in diesel fuel tanks, it proved that the problem is much larger than anyone anticipated. The facts are staggering: 83%of the diesel tank systems exhibited moderate-to-severe corrosion. 75%of the owner/operators of those diesel tanks had no idea it was ...

  • Integrity management: how direct assessment is improving pipeline inspection

    Oil and gas pipelines have been around for well over a century, and some of the earliest constructed are still in service today.  Although early pipelines were made of wood, and in the past few decades plastics and composite materials have increased in popularity, the vast majority of pipelines in service today are constructed with steel.  Like any pipe material, steel pipe has its ...

  • Case study - Safety, Protection against corrosion and cabinet pressurisation in refineries

    The environment in a refinery is highly corrosive. This makes it necessary to deploy control systems not only to protect staff but also to protect the equipment controlling the processes, in order to ensure their reliability. Bioconservacion has equipment that is specially designed for the safety of staff, and for protecting against corrosion in control rooms and cabinet pressurisation equipment. ...

  • How UV can reduce corrosion in swimming pool structure - Case Study

    In 1985, twelve people were killed in Uster, Switzerland when the concrete roof of a swimming pool collapsed after only thirteen years of use.  The roof was supported by stainless steel rods in tension, which failed.  The Federal Materials Testing Institute, based in Duebendorf, Switzerland, and the Federal Materials Research and Testing Institute of Berlin concluded that the collapse ...

  • Corrosion and fouling control in process equipment

    Effective chemical treatment programmes can help to prevent plant damage and financial losses arising from corrosion and fouling. Corrosion attack is an omnipresent threat in oil refineries and petrochemical plants. It may lead to loss of production, cost of maintenance and repairs, replacement cost for equipment, safety aspects and potential environmental impact. If corrosion is ...

  • Evaluation of corrosion and scaling tendency indices in a drinking water distribution system: a case study of Bandar Abbas city, Iran

    Corrosion and scaling is a major problem in water distribution systems, thus evaluation of water corrosivity properties is a routine test in water networks. To evaluate water stability in the Bandar Abbas water distribution system, the network was divided into 15 clusters and 45 samples were taken. Langelier, Ryznar, Puckorius, Larson–Skold (LS) and Aggressive indices were determined and ...

  • Aminomethylphosphonic acid (AMPA) has low chronic toxicity to Daphnia magna and Pimephales promelas

    Aminomethylphosphonic acid (AMPA) is the simplest member of a class of compounds known as aminomethylenephosphonates and the only environmental metabolite measured in significant amounts during the degradation of the herbicide glyphosate in soil. However, there are additional sources of AMPA in the environment, originating from organic phosphonates which are used in water treatment to inhibit ...

  • Failure analysis showing the effect of sulphur content in stainless steel on the resistance to stress corrosion cracking in marine environments at ambient temperatures

    The risk of environmentally assisted cracking in downhole components is high due to sour conditions, i.e. the presence of hydrogen sulphide. Therefore a range of materials possessing excellent corrosion resistance are employed. However, corrosion is not only downhole related but is also a common problem on the platform deck itself due to airborne salts from ocean spray. For this reason the ...

  • Combating Corrosion - Committee G01 Standards Fight Nature’s Destructive Tendencies

    The evening news may leave many of us feeling war-weary, but one ASTM International technical committee has been successful in conflict of a different sort. It’s a commonplace but epic struggle between the natural and civilized worlds — the fight against metal corrosion. For the past half-century, the weapon of choice of ASTM Committee ...

  • In practice: M2M technology and H2S

    Coping with H2S is a crucial topic. Besides causing unpleasant odours, hydrogen sulfide can also lead to corrosion of important components as well as damages to health. Microtronics supports experts in water and wastewater treatment in coping with H2S with various M2M products and a platform. In practice there are different forms of applications. The measurment and transmission of ...

  • Wear and corrosion preventative solutions to increase power plant efficiency

    For many years energy demand has been strongly growing and will continue. The installation of new plant capacity can take years so there is an enormous pressure on power plants to improve operational output, efficiency and availability. Component repair rather than replacement produces immediate costs savings and also reduces the use of materials, energy and transport in ...

  • Successful corrosion strategy through good practice guidance

    Corrosion is a hugely significant issue to the oil and gas industry. This is especially true in marginal development projects where tight profit margins are in play and an unplanned failure in a key component or system can rapidly lead to the premature closure of the associated well, or even field, and a reduction in returns on investment to operators and shareholders. Here, Dr Cameron Stewart, ...

  • HVAC technicians turn to RYDALL CC for its indoor/outdoor capabilities and non-corrosiveness case study

    The service technicians at a major HVAC company decided to put RYDALL CC  to the test against the coil cleaners they had been using for years.  These seasoned technicians were skeptical, but agreed to the test it when they learned that RYDALL CC  can be used both indoors and outdoors, will not harm roofing materials and is biodegradable! RYDALL CC  approach ...

  • Addressing Dead-Legs and Corrosion Issues in a PHA

    This case study describes a systematic approach for process hazard analyses (PHAs) and revalidations to identify and address corrosion and dead-leg concerns.   It is especially important during project (MOC) PHAs and revalidations of systems that have experienced changes to uncover potential issues. Systematically approaching revalidations can uncover dead-legs created by a previous ...
