AI Technical Summary
Existing sleeve compensators experience a decrease in sealing performance when pipelines expand and contract due to thermal changes, leading to fluid leakage. Sudden leaks require immediate shutdown for maintenance, resulting in economic losses.
A sleeve compensator was designed, comprising an emergency device bellows, which is sealed and welded to the inner tube. It is used to take over the sealing function when the sealing performance of the sealing packing deteriorates, and to prevent media leakage. The compensator includes a welded structure of bellows and pressure sleeve.
This technology enables the bellows to take over the sealing function when the sealing performance of the sealing packing deteriorates, thus avoiding sudden pipeline shutdowns, extending maintenance cycles, reducing maintenance frequency, and preventing media leakage.
