PPE Spring Seals for High-Pressure ApplicationsPrecision Polymer Engineering has broadened its range of advanced sealing solutions aimed at high-pressure oil & gas applications, including a range of spring seals-elastomer seals that incorporate a spring and are therefore suitable for applications encountering high pressures, high temperatures, or aggressive media. These seals are uniquely available from PPE in their Perlast and Endura materials suitable for extreme environments and applications such as downhole, wellhead, surface equipment, and high-pressure pipeline and riser systems. The new seals incorporate a double internal spring that can be made from Inconel Alloy, stainless steel, or PEEK. The springs prevent the extrusion of the seal when pressure is applied thus maintaining the integrity of the seal under extreme pressure. The PEEK version of the springs also eliminates metal-to-metal contact, reducing wear and extending the operational lifetime of equipment using this type of seal. Initially, PPE’s spring seals will be available from 60mm to 850mm (2½” to 33½”) internal diameter and between 3.53 and 8.4mm (0.14” to 0.33”) cross section. Larger and smaller sizes will also be available in the future.
