Tyco - an AVID provider of the latest technology
A comprehensive integrated system of control accessories designed for hazardous area or general process applications, is provided by the state-of-the-art AVID range from Tyco Valves and Controls
Tyco was selected by Chevron Texaco in 1998 to instigate a root based inspection programme to ensure the reliability of pressure relief valves on site, as well as providing full time on-site coordination and spares for all 2729 pressure safety relief valves at the plant.
By implementing the Tyco performance history database software (PhD) the partnership has had success in collating performance history data on each valve, and scheduling an accurate valve servicing programme.
This has increased efficiency on site and led to a significant reduction in maintenance costs and in spares stock.

Lined butterfly valves for corrosive applications
For demanding or corrosive processes in the chemical, pharmaceutical, cosmetic and food industries where common elastomers are unsuitable, Neotecha has developed the lined NeoSeal butterfly valve
A root based inspection (RBI) programme has improved valve reliability at the plant and has resulted in far fewer failures between service intervals.
The programme covers complete disassembly of each valve and inspection to OEM standards.
The partnership also instigated a root cause failure analysis (RCFA) programme to identify the cause of valve non-conformity.
This has enabled plant engineers to identify and remove problem valves, and has highlighted areas for improved installation practices in order to prevent recurrence.
Project coordinator, Andrew Evans says: "Since the first quarter of 2004 we have successfully maintained a zero overdue pressure relief valve listing site wide, which is an excellent achievement.
This means that every single pressure relief valve is now fully compliant with the health and safety executive regulations".
The Tyco valve management contract deals primarily with pressure relief, thermal relief, pressure vacuum and vacuum safety valves.
Tyco also provides new, replacement valves, including instrumentation, gate and ball valves to Texaco Chevron.
In addition to the valve asset management services that have been implemented, Tyco Valves and Control has provided ChevronTexaco staff with detailed guidance on safety codes and practices, and comprehensive training on pressure relief valve repair.
