Pressure monitoring and valve control in one
esigned for use in the oil and gas industries, the Rotork ELB is a robust, self-contained instrument that combines pipeline pressure monitoring with intelligent valve control. It can also collect detailed operational data for optimising performance and enhancing pipeline safety. The ELB continuously monitors
D
upstream and downstream pipeline pressure dynamics to provide early detection of pipeline breaks and initiate automatic valve actuator movement to an emergency position, based on user-defined parameters. Valve actuator control - selectable as fail close, fail open or stay put - is based on rate-of-drop (RoD) and rate- of-rise (RoR) as well as high and low pressure limits. A remote process shut down (PSD) input with the option to override all functions is also available to drive the valve to the fail position. The ELB also provides an array
of programmable alarm and alert indications and has an extensive range of features that can be configured to
The ELB (on the left side of image) attached to a Rotork gas-over-oil pipeline actuator
meet end users’ specific requirements. These include up to six remote inputs and four configurable solenoid outputs, partial stroke testing (PST) and Modbus network connectivity. The PST function is particularly
useful for long-term asset management. When PST is activated either remotely or locally, the actuator moves the valve from the open position to a set point in mid travel and then back to its open position without causing any disruption to
routine pipeline operation. If the set point is not reached within a specified time, indicating a potential valve fault, an alarm is signalled, enabling the fault to be investigated and eliminated before it can cause a serious problem. The ELB is housed in a compact,
environmentally sealed and explosion- proof housing that can be mounted on the actuator or remotely. Setting menus displayed on the large HMI window are the focus for non-intrusive programming and commissioning using Rotork IQ intelligent electric actuation technology. In normal mode the LCD display indicates valve position. The same window also displays visual indication of status, alarms, event, trend and operation logs and diagnostic data. Padlockable pushbuttons for local actuator operation are provided on the ELB enclosure and a vandal-proof cover is available for increased security. l

India embraces high-performance tubes A
t India’s recent Petrotech exhibition, Fine Tubes and Superior Tube presented their precision
tubing solutions. The companies have been manufacturing high performance tubing for India’s oil and gas companies for nearly five years and continue to see great potential in India for further growth. Rahul Gujar, who works for the firms
in the Indian marketplace says: “Rapid economic growth in India requires greater oil and gas output. This in turn pushes the demand for more oil and gas production. There is a 9.1% year-on-year growth in the oil and gas sector in India, which is substantial. So, the market is positive and has great potential.” Fine Tubes and Superior Tube develop high quality, advanced

alloy tubing solutions for the most demanding oil and gas applications. As far as examples for success in India are concerned, Fine Tubes recently received approval from India’s Oil and Natural Gas Corporation Limited (ONGC) to supply instrumentation tubing for offshore applications and was also awarded the project to supply downhole control lines. US-based sister company, Superior Tube, was awarded a major contract from TEMA India to supply heat exchanger tubing for a new floating production storage and offloading (FPSO) vessel. At the Petrotech exhibition, the two companies presented their chemical injection lines and control line tubes together with a selection of corrosion-
resistant coil and instrumentation tubing for critical offshore applications. The exhibition was an opportunity for both businesses to showcase their various approvals and extensive range of speciality stainless steel tubing. This included NORSOK-approved 6 Moly and Super Duplex as well as a range of nickel alloy and titanium grades. Oil and gas companies in India look
to Fine Tubes and Superior Tube for their expertise in processing exotic alloys to manufacture high quality tubing solutions that meet their customised technical specifications. l
