High-pressure and high-temperature (HPHT) Feed-through for Extreme Environment Interconnect

Sunkye's Glass-Metal Feed-through Offers Reliability in Demanding Subsea Environments

High-pressure and high-temperature (HPHT) feed-through, the single- and multi-channel penetrators are designed to operate reliably in the extreme environments typically found in subsea oil and gas applications.

When the subsea well gets deeper and deeper, temperature and pressure increasingly raise, it’s a huge challenge to the materials and technology of connectors. Sunkye's glass to metal feed through seal connectors are doing well in electrical signals communication from downhole pressure and temperature sensors in subsea oil and gas environments.

Glass-to-metal seals providing the main protection and electrical isolation for the feed-through metallic contact from the external seawater environment while ensuring the highest level of reliability under long-term installation at extreme pressures and temperatures.

As one of the professional electrical connector suppliers, Sunkye is uniquely qualified to deliver turnkey custom solutions for a complete range of High-Pressure, High-Temperature (HPHT) applications. Our industry-leading materials knowledge, engineering design experience, and testing capabilities are key to achieving reliable service in the most extreme HPHT environments.
