Sealing damaged flanges F
lexitallic has launched the first solution to sealing damaged flanges without the need for
replacement or machining - the Flange Rescue Gasket (FRG).
The FRG is developed in response to customer demand for a sealing solution to reduce the lengthy and costly process of flange maintenance in corrosive offshore environments.
Flexitallic surpassed requirements by creating the FRG which negates flange replacement or machining, potentially reducing flange inspection by 24 hours, and also prevents further corrosion. Previously, sealing issues with corroded flanges have discouraged frequent inspection. Now, flanges can easily be inspected and sealed effectively enabling fast, accurate assessment of internal corrosion.
Shutdowns with associated HSE visits are dramatically reduced, as is the huge loss of revenue.
Flexitallic’s revolutionary sealing technology, highly compressible Sigma,
ensures the FRG conforms to damaged flange surfaces to seal and prevent further deterioration. Restructured Sigma PTFE bonded to the high integrity serrated metal ring provides a leak-free seal and blow out resistance. The bright, easily identifiable FRG has a PTFE coated corrosion resistant body and integral bolt holes for ease of installation and ensures correct location.
Superior mechanical integrity allows full range of torque reducing the risk of operator error, meeting stringent Health & Safety Executive standards.
From corrosion management to health
and safety, through environmental impact to incident avoidance, the Flange Rescue Gasket is, says Flexitallic, dramatically changing flange inspection and maintenance forever. n

Online condition monitoring
C
extended at steel plant
orus engineers at the Medium Section Mill in Scunthorpe, UK, are planning to extend condition
monitoring activities throughout the plant with online vibration devices.
The Medium Section Mill at Corus Scunthorpe supplies railway lines and steel rail sleepers, as well as sections for the construction industry. The plant has been in operation for three years and consists of one abrasive saw that cuts hot rails, and four cold saws.
Engineers had been undertaking basic plant condition monitoring on the saw lines for some time. However, following a review of the area, the plant became a locked access area to comply with health and safety requirements.
Save energy and money on your existing thermal installations
M
ost thermal installations in operation today are equipped with conventional gas or oil
fired burners that use traditional control mechanisms. n the past decade there have been many
important developments in both combustion technology inside the burner and in the way fuel control systems are engineered. If you are considering a retrofit, it is very important to have your installation checked by a specialised company who can advise you on how an upgrade can affect your burner and overall system performance.
The investment in latest generation equipment will typically pay for itself due to fuel cost savings alone.
Furthermore, upgrading an older gas or oil control system to comply with the latest European directives and standards will lead to safer equipment, thus lowering the risks of incidents and plant downtime.

Access to the area is restricted by a Castell key system. This trapped key interlock safety system isolates the plant by ensuring that personnel cannot gain access to the locked gates surrounding the area until the power has been confirmed as switched off. This makes it impossible to conduct vibration monitoring using hand held devices, forcing engineers to consider various online systems.
Following the success of Schaeffler’s
FAG DTECT X1 online vibration monitoring system, which monitors the hot saw gearbox in the Beam Mill at Corus’ sister plant in Redcar, Teesside, it was agreed to look at a similar system for Scunthorpe. FAG ProCheck is an online condition monitoring system that enables companies to monitor vibration levels on critical rotating plant or machinery, including electric motors, drives, bearing arrangements, gearboxes, pumps, generators, ventilators, fans and excavators. Its modular design means it can cater for different maintenance and condition monitoring strategies. FAG ProCheck operates automatically without further intervention from the user, to measure, record, analyse and issue alerts on vibration data from rotating plant. By continuously monitoring a machine or piece of rotating equipment, FAG ProCheck can detect changes and alert personnel. n
