ATEX compliance achieved for complete seal range
NEWS
Busak+Shamban decompressionresistant elastomer certified IsolastJ9510, a perfluoroelastomer developed by Busak+Shamban for sealing in hazardous environments, has received independent certification of its use in explosive decompression situations. This included 30 decompression cycles with no resultant damage or leakage. The test parameters included: • • • •
Test gas: natural gas Test temperature: 80ºC Test pressure: 138 bar Decompression rate: 12 minutes
The material is developed and manufactured within the Busak+Shamban group of companies and is available in a complete range of standard and special O-rings and custom parts for the offshore and processing industries.

STLE invites sealing participation for its 2004 annual meeting The Seals Technical Committee of STLE is inviting papers for presentation at the 2004 Annual Meeting to be held on 16–20 May 2004 in Toronto, Canada. In addition to the traditionally strong presentations on mechanical seal technology, STLE wishes to include more papers on other sealing technologies. These could include lip seals, labyrinth, brush and special sealing systems. To ensure publication of a paper, the
manuscript will be required by 1 October 2003. Offer of paper forms can be submitted via the STLE website at the address given below.

IN BRIEF Cooperation provides cable conduit Bayer Chemicals, a division of Bayer AG, and the Swiss company IBMO International based in Rotkreuz have pooled their knowhow to develop a cable conduit seal for ships and offshore rigs. In an emergency, the fire-retardant IBMO cable conduits based on the two-component Bayer raw material system Bayfomox prevent fire and smoke break-
through. They have been tested according to the IMO (International Marine Organization) A 754 (18) A 60 Class Division Certification. The cable conduit seals have been specially adapted to the specific construction requirements of marine engineering where “openings” for electrical installations are often very difficult to close again.
New product offers intelligent control of seal water systems Seal water savings of up to 97% are now available from a new water control system launched by Safematic. By optimizing seal water consumption, the new SmartFlow intelligent control system creates an effective, reliable and economical way to combine optimum seal performance with significantly reduced costs. In many systems, the water used to cool mechanical seals and lubricate seal faces is filtered before use and then treated prior to disposal. The system minimizes the volume of water used for cooling by allowing water through to the seal only when cooling is actually required This is achieved by a heat-activated shape memory alloy spring that opens and closes the flow channel according to fluctuating temperatures. It is able to
adapt automatically to different pressure and temperature conditions. The compact unit also filters the water prior to use. It is based on proven technology, is easily installed, needs no wiring or electrical supply, provides reliable operation and is said to be virtually maintenance free. The fail-safe design also prevents seal failure in the event of a fault developing. The SmartFlow can be coupled with a Safeunit flowmeter; which will monitor seal water performance, auto-detect failures in advance, and warn of seal water leakage.

ATEX compliance achieved for complete seal range AESSEAL has achieved full ATEX compliance across the entire range of mechanical seals and systems that it produces. The European Directive 94/9/EC, commonly referred to as ATEX, became legislation at the end of June 2003. From then on it will be an offence to supply new equipment into areas where there may be an explosive atmosphere without a proper certificate of conformity. While this only applies to the European Union, it is estimated that as many as 20% of all future AESSEAL seals and systems could be affected. AESSEAL has assessed all of its products from the simplest
Sealing Technology September 2003
of single spring seals through to the most complicated of mixer seals and systems. Ian Smedley, technical support manager, said “AESSEAL’s modular design policy helped significantly with the certification process, which, during the course of the assessment, highlighted what excellent products we already produce.” Contact: AESSEAL Plc, Mangham Road, Barbot Hall Industrial Estate, Rotherham, S61 4RJ, UK.
