Parker Instrumentation, Barnstaple, UK, has developed an instrumentation manifold for BP’s Grangemouth oil and gas complex. The new design allows pressure transmitters to be connected directly to process pipelines without the conventional taper threaded connection providing a seal that requires no thread sealants. Manufactured from a single forging, this manifold reduces the leak paths to the absolute minimum of one, and connects by simply aligning the faces and tightening four bolts. Incorporated into the body of the manifold are three valves providing a ’double block and bleed’ facility to aid installation and maintenance.
