TIS Order Sees SS-690 Reworked For Remote Subsea Operation

Pressure Tech were asked to provide a design solution to enable the remote set point control of one of our subsea regulators during its service under water. A regulator’s set point is configured during its build at our unit in Glossop, UK. The regulator is then supplied as ‘set and lock’ - any changes after this point must be physically conducted, either prior to system installation or during maintenance intervals. Our solution? A closed loop actuator enabling the customer to control set pressure point constantly via an electronic signal during regulator operation. The actuator is fully sealed, IP69K rated and has a sea water depth rating of up to 3000m.

Pressure Tech Supplies Saudi Aramco for Fadhili Project

The Fadhili gas plant is a greenfield development being constructed by Saudi Aramco, 30km west of Jubail in Saudi Arabia with an estimated investment of approx £10.5bn. It is part of Saudi Arabia's proposed Master Gas System to help meet its increasing energy demand. Pressure Tech were contacted to supply several regulators from our Analyser range, including TS-310's, LF-310's and XHS-310's, to a project order value of £45k. A further order has been received this month for the next phase of the Fadhili Project, taking the ongoing project value up to a total of £70k to date.

Fast, Bespoke and On-Time for Wheatstone Project

A client called on Pressure Tech to replace competitor units that were unsuitable for their application, and importantly before their scheduled shut-down. The proposed regulators had to be piston-sensed to eliminate any chance of rupture and control low pressures down to 1.5bar (20psi). They also required exact face-to face dimensions to ensure seamless installation to existing pipework. Pressure Tech designed, approved, manufactured, tested and delivered a solution in just eight weeks.

Why Did Corrosion and Nesting Bees Lead to the Development of Our Protective Sleeve? Why did corrosion of the regulator’s internal mechanism and nesting bees lead to the development of our PT-C-180 Protective Sleeve? PT-C-180 Protective Sleeve By design, a regulator’s bonnet features a ‘key slot’ opening which is necessary for the correct operation of its adjusting mechanism. Consequently, this opening leaves the internal components exposed to external conditions - in certain environments this can be particularly problematic. In offshore and other locations close to the sea, the salt content in the air is high which can potentially result in a crystal build-up on the adjusting screw and accelerate corrosion of the loading spring. In one instance we were also told of bees building a nest inside the regulator! This meant that we needed to design something that could not only close the slot, but was simple in application, reusable, long-lasting and, ideally, environmentally-friendly. Our senior design engineer, Karol Wolniewicz, is a keen scuba diver and used his experience to explore the option of utilising a rubber sleeve to create a ‘dry seal’ between the bonnet and band. Initially we experimented with trialling heat shrink tubes and sections of dry suit cuffs to test which gave better results. The heat shrink didn’t perform sufficiently and also wasn’t reusable. The dry suit cuffs, however, seemed perfect for the application. We successfully located a manufacturer who was able to supply them to our specification, allowing us to offer our PT-C-180 Protective Sleeve to customers across the world and prevent those issues that were first identified in some of the more challenging environments from happening. Our Protective Sleeve meets all of the criteria we initially set out to achieve; it offers excellent ozone, UV and chemical resistance in a range of temperatures from as low as -50°C right up to +1 10°C, and is 100% recyclable. Job done!
