Instrumentation Manifolds
Description: Instrumentation manifolds have been launched meeting the stringent new ISO 15848 standard for fugitive emissions. Available in double-block-and-bleed configurations, in either mono-flange or low-profile flange-ended forms, the new manifolds provide process instrument interfaces of outstanding integrity to help processing organisations dramatically enhance their LDAR (leak detection and repair) programs. Published in 2006, ISO 15848 parts 1 and 2 (defining a classification system and qualification procedures, and production acceptance test of industrial valves, respectively) specify new ultra-low standards for emissions, which are attracting the attention of oil, gas and chemical/petrochemical organisations worldwide. There are three leakage classifications specified by ISO 15848: A, B and C specifying maximum leakage rates from less than or equal to 1 x 10-2 mg/second/metre, to a figure four orders of magnitude less: 1 x 10-6 mg/second/metre. Meeting any of these low levels is a challenge, which has been solved with new ball and needle valve designs for use in double-block-and-bleed instrument manifolds. The valve designs meet the highest A classification level, over the temperature range - 29 to +180°C, and the standard instrumentation manifold working pressures.
