For example, North Sea offshore pro-duction facilities built in the 1970s and 1980s have already exceeded their 25 year design life. The average age of Norways offshore instal-lations is near 25 years approaching the intended productive lifespan. According to energy research and analysis firm Infield, there are more than 2500 platforms in the Gulf of Mexico that are approaching or have exceeded their design life. Similar situations exist in the Middle East, Brazil, West Africa and in South East Asia. The Middle East has about 500 plat-</p><p>forms with an average age exceeding 28 years. Indonesia and Malaysia combined have more than 1000 platforms with an average age of 20 years, says the firm.</p><p>Increased age brings inevitable degradation to assets, and especially joints, says Hydratight. Whilst existing offshore assets are compelled to remain on-line, their lifespan must be pro-longed safely and efficiently. It says that its pat-ented Hot Bolt Clamp is a robust system that provides the highest mitigation of risk of flange or gasket damage, or worse, a leak.</p><p>The philosophy behind the design is to mini-mise the possibility of disturbing the gasket. It does not require any pneumatics or hydraulics for clamp engagement, nor does it increase the load on the gasket. The lightweight and compact design fits almost all flange space restrictions. It is also easy to handle and fit, which enables bolts to be replaced speedily. Furthermore, it is designed and tested in accordance with the ASME VIII Division 2 standard.</p><p>Continued on page 16...</p><p>Hydratight Ltd offers safe, hot bolting services on all ASME flanges. These are performed without any damage, leakages or interruption to daily production.</p><p>http://www.sealingtechnology.info</p></li><li><p>NEWS</p><p>2</p><p>Cable seal specialist upgrades UK nuclear sites flood defences</p><p>The UK subsidiary of global, safety seal manufacturer Roxtec has pro-vided cable and pipe sealing systems for a major flood protection project at a nuclear power station in the UK.</p><p>Managing director of Roxtecs UK arm, Graham OHare, says the firm worked with EDF Energy, which operates the Dungeness B nuclear power station on the coast of Kent, to develop the necessary systems.</p><p>OHare said: Roxtecs products were used to seal pipes and cables in existing underground trenches to protect the power stations diesel generators. These are extremely important because they are needed to provide emergency back-up. Furthermore, the trenches go under bund walls, which provide an important sec-ondary line of protection or containment.</p><p>Roxtec was chosen because its seals protect against multiple hazards. The penetration seals meet an IP67 rating for water ingress, possess an H class fire-rating and can protect against diesel splashes. Traditional sealants will only protect against one particular hazard and, therefore, could not meet the demands of this project.</p><p>Roxtec engineers visited and surveyed the Dungeness plant before coming up with the required designs. The company then manufac-tured retrofit products that seal around existing cables and pipes so as not to disturb the sur-rounding infrastructure.</p><p>The Dungeness project comes as Roxtec, which has its UK arm based in Greater Manchester, recently reported a 45% growth in the past year as sales passed the 5 million mark.</p><p>Contact: </p><p>Roxtec Ltd, Unit C1, Waterfold Business Park, Bury, </p><p>Lancashire BL9 7BQ, UK.

These characteristics are vital for components such as bearings, seals and gaskets used in applications that need to withstand ongoing heat and pressure.</p><p>Although fluoropolymer resins alone impart characteristics such as a low coefficient of fric-tion, chemical resistance and a wide service temperature range, fillers such as glass, bronze and graphite can greatly enhance their perfor-mance, says the company.</p><p>By compounding PTFE resins with pigments and fillers, the firm creates custom low-flow (non-pelletised) and free-flow (pelletised) com-pounds. Low-flow compounds are manufactured in powder form and are used in applications that demand the highest mechanical strength, whilst free-flow compounds increase bulk density and mould-flow properties, which enable consistent manufacturing of seals, gaskets and rings.</p><p>Customisation is key in fluoropolymer compounding because selecting the appropri-ate filler is strongly application-dependent. Fillers must be compatible with PTFE in order to retain optimal performance properties, explained Gary Eckrote, Business Director, AGC FluoroCompounds Group.</p><p>Contact: </p><p>AGC Chemicals Americas Inc, 55 E. </p><p>Uwchlan Avenue, Suite 201, Exton, PA 19341, USA. </p><p>Tel: +1 610 423 4300, Web: www.fluorocompounds.com</p><p>Ketron 1000 meets sour gas single-phase conditions at high H2S levels</p><p>Quadrant Engineering Plastic Products (EPP), which special-Sealing Technology January 2015</p><p>Editorial Office: Elsevier Ltd </p><p>The Boulevard, Langford Lane Kidlington, Oxford OX5 1GB, UK </p><p>Fax: +44 (0)1865 843973Web: www.sealingtechnology.info</p><p>Publisher: Greg ValeroE-mail: g.valero@elsevier.com</p><p>Editor: Simon AtkinsonTel: +44 (0) 1904 655944</p><p>E-mail: sealingtechnology@googlemail.com</p><p>Technical Editor: Bob Flitney Tel: +44 (0)1799 501659 </p><p>E-mail: robert.flitney@ntlworld.com </p><p>Production Support Manager: Lin LucasE-mail: l.lucas@elsevier.com</p><p>Editorial advisory board: Yves Birembaut (F) Cyril X Latty (F) </p><p>Amrat Parmar (UK) Richard F Salant (USA) Wolfgang Schpplein (D) Shuzo Seya (J) </p><p>Scott Svendsen (USA)</p><p>Subscription InformationAn annual subscription to Sealing Technology includes 12 issues and online access for up to 5 users.Prices: E1215 for all European countries &amp; Iran US$1362 for all countries except Europe and Japan 161 400 for Japan (Prices valid until 31 January 2015)To subscribe send payment to the address above.
