- Installation and Mimic Video of a Linear Compensator
In order to ensure reliable insulation even after an overvoltage, SCHUCK insulating joints type SHD are equipped with the patented ring spark gap. This protects the insulating joint from carbonizing of the insulating materials by tear down the overvoltage at a defined point without damaging the component.
After the inspection had been successfully completed, the installation of the linear compensator in the pipeline in the 168 km long underfloor high-pressure pipeline from Pogórska Wola to Tworzeń began in April.
The SMP (Schuck Mechanical Partial Test Device) is installed between the valve and the actuator and, if necessary, is manually unlocked in order to carry out the PVST. The limitation of the rotation of the valve of approx. 20 ° is already preset with a start-up block. Optionally, a position switch is also supplied to document the process in the control room.
In the underfloor gas pipeline, which is to go into operation in the new years, 42 of these pipeline linear compensators with a nominal width of DN 1000, a nominal pressure of PN 84 and a new design are used for integration into a KKS system.
The VAG pipeline is 388 km in length and 36” in diameter and will supply natural gas to the areas of San Luis Potosi, Aguascalientes and Guadalajara, as well as other regions of the country such as Colima, Michoacan and central Mexico via its links.
