Pressure Sealing is a technique for quickly plugging leak points in equipment or pipelines without stopping operation or releasing pressure, with the core principle being to isolate the medium through sealing materials or mechanical structures.

Core Principle

Establish a temporary sealed cavity using specialized tools, inject the sealant into the cavity, fill the leakage gap, and cure it.

Using mechanical clamping force, the sealing material is tightly bonded to the leak surface, forming a reliable sealing layer.

Applicable Scenarios

Industrial pipeline and pressure vessel gas and liquid leaks, including water, oil, steam, and chemical media.

Critical equipment that cannot be shut down for pressure relief, such as power plants, chemical factories, and oil refineries' operating systems.

Common Methods

Mechanical sealing method: Directly presses the sealing part using clamps, bands, and other mechanical devices, suitable for leaks in flange and pipe welds.

Sealant Leak Sealing Method: Injects high polymer sealant to form a solid sealing layer at the leak point, suitable for complex leak shapes.

Welding Sealing Method: Directly seals metal materials using special welding techniques, requiring professional operation.
