Pressure Tech’s LF690 providing reliability to Protec
14 January 2016Protec, a manufacturing, design and assembly business, specialising in modular skid mounted equipment for the onshore and offshore oil and gas industry, has been using Pressure Tech’s LF690 and LF691 regulators in the test HPU’s they have been providing to companies including FMC, ExxonMobil, Tullow, etc., and in some IWOCS HPU’s. They have seen some great results from their testing facility in Houston, Texas and have since made these two regulator models available to all of their clients.
Bill Thrasher of Protec explains ‘Pressure Tech’s regulators are being used as an intentional replacement for a circuit that is inherently subject to difficult operational conditions that were causing chatter in the regulators manufactured by others. We have had great success in relation to performance, with the units which Pressure Tech’s regulators are on. As experienced users of the competitions pressure regulators, we are familiar with the problems of chatter and the detriment to reliability it brings, both in regards to the HPU in operation and to the equipment "operated". We have seen those issues completely eliminated by Pressure Tech’s regulators."
Protec tested two of Pressure Tech’s regulator models, the LF690 and LF691, making them available to clients in late 2013. This has enabled the organisation to assess operational history and performance over a minimum of 2 years, providing results which show Pressure Tech’s regulators have eliminated the problems Protec had previously experienced, with the added benefit that they have not required any servicing.
The LF-690 uses Ceramic Seating to provide ultimate protection against the harsh service encountered on hydraulic services. The unique seating cartridge provides a dampening action on this critical component to prevent 'chattering' or 'unstable frequency resonance'. The regulator is self-relieving with segregated captured vent to prevent deterioration to the loading mechanism and making the regulator cleaner to service. The seating area can easily be accessed from the base of the regulator for speedy servicing in situ.
