DBBV passes fugitive emission tests

Nether Seal has successfully tested their Dual expanding double block and bleed plug valves (DBBV) within the specifications of the Shell MESC SPE 77/312 for Fugitive emission production testing. The helium leak fugitive emission tests have been carried out at APPLUS/RTD and have been witnessed by a Shell appointed third party inspector. During the tests, the performance of the Nether Seal DBBV proved excellent results meeting the specification requirements by far. The DBBV are for Crude Oil Metering (skid mounted installation) and for installation in a West-African Terminal Upgrade Project. The valves, 10 pieces size 16in ANSI class 300, supplied for this project have all been mounted with Rotork electric actuators and with integral 1/2in Class 300 RF flanged bleed system connections. This special execution has been exclusively designed and executed for this contract. The net weight of each valve and actuator unit is 1600kg. All usual pressure hydrostatic testing as well as the inspection on the 3 layer off shore coating and packing has been witnessed by Shell appointed third party inspector.
