GERDA-PGE "Pikotek" is a disk-type flange gasket designed for low-pressure pipelines up to 7 MPa. It provides high sealing performance and electrical insulation of flanges, ideal for systems with cathodic protection. It minimizes galvanic corrosion between dissimilar metal flanges, protects surfaces from erosion, and prevents leaks common with layered materials. Available in ring type (F) and full-face type (E). Easy to install and remove, requiring minimal bolt torque.
The GERDA-VCFS "Pikotek" fire-resistant combined disk gasket builds on the proven VCS design and adds dual-sealing technology for API 6FB (3rd ed.) fire resistance. It provides effective flange sealing at pressures up to 105 MPa, excellent electrical insulation for cathodic protection systems, and resistance to harsh media like CO₂, H₂S, and formation water. The design reduces flange misalignment under lateral load and is suitable for repeated use. Easy to install and corrosion-resistant.
The GERDA-VCS “Pikotek” combined disk-type flange gasket is built for Very Critical Service conditions. It offers tight sealing and electrical insulation for flanges in systems exposed to aggressive environments like CO₂, H₂S, and formation water. With pressure resistance up to 105 MPa (15000 psi), it fits RF, FF, and RTJ flanges, helps prevent galvanic corrosion, and protects metal surfaces. Easy to install and reusable.
