Pressure-sealing is an extension of pressure stopping technology, focusing on long-term sealing of pipes/equipment without production halt or pressure release, commonly used in scenarios requiring long-term reliable sealing.

Key Differentiation (from conventional pressure sealant)

Routine pressure sealant is often used for temporary emergencies, while pressure sealing is more focused on long-term sealing effectiveness.

Pressure-sealed plugging often incorporates welding, flange connections, etc., suitable for systems requiring long-term operation.

Primary Application Scenarios

Long-term repair for pipeline corrosion perforation and weld cracks, especially suitable for conveying pipelines.

Sealing off leaks in equipment bodies post-leakage, such as repairing localized damage in pressure vessels and storage tanks.

Temporary sealing during pipeline rerouting and branch connection, with sealing operations.

Safety Core Requirements

Welding sealing requires anti-spatter technology to prevent ignition of the leaked medium.

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

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