Pressure Sealant is a technique for quickly sealing leak points without stopping the equipment or pipelines and without 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.

Utilizing mechanical clamping force, the sealing material is tightly bonded to the leakage 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 depressurization, such as power plants, chemical factories, and oil refineries' operating systems.

Common Methods

Mechanical sealing method: Directly compresses the sealing components using clamps, gaskets, and other mechanical devices, suitable for flange and pipeline weld leakage.

Sealant leak plugging method: Injects high molecular weight sealant to form a solid sealing layer at the leak point, suitable for complex leak shapes.

Welding plug method: Directly seals metal materials using special welding techniques, requiring professional operation.
