Pressure Sealing is a technique for quickly plugging leak points on 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 temporary sealed cavities using specialized tools, inject sealant into the cavities, fill the leakage gaps, and cure.

Utilize mechanical clamping force to tightly seal the sealing material against 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' operational systems.

Common Methods

Mechanical sealing method: Directly tightens sealing components with clamps, grommets, and other mechanical devices, suitable for leakage in flange and pipeline weld seams.

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

Welding Leak Sealing Method: For metal materials, a special welding technique is used to directly seal the leaks, requiring professional operation.
