Pressure Seal is an extension technology of Pressure Sealant, focusing on long-term sealing of pipelines/equipment without halting production or releasing pressure, commonly used in scenarios requiring long-term reliable sealing.

Key Distinction (from conventional pressure sealing)

Conventional pressure-sealing is typically for temporary emergency purposes, while pressure sealing is more focused on long-term sealing effects.

Pressure Seal Plugs are often combined with welding, flange connections, and other structures, suitable for systems requiring long-term operation.

Main Application Scenarios

Long-term repairs for pipeline corrosion perforations and weld cracks, particularly suitable for conveying pipelines.

Post-leakage integrity sealing of equipment, such as local repair of partial damage in pressure vessels and storage tanks.

Temporary sealing for pipeline rerouting and branch connections, combined with sealing operations.

Safety Core Requirements

Welding plug sealing requires anti-splatter technology to prevent ignition of the leaking medium.

During high-pressure and toxic medium operations, real-time gas detection equipment must be provided, with a dedicated person supervising throughout the process.

Barrier materials must be long-term compatible with the medium to avoid aging,
