Pressure plugging is a common technique used to plug pipes, holes, or cracks to prevent fluid from being blocked by pressure

Pressure plugging is a common technique used to plug pipes, holes, or cracks to stop fluid leakage. Below are some common types and characteristics of pressure sealing materials, I hope to help you.

1. Rubber sealant: Rubber sealant is a commonly used sealing material with pressure, usually used to seal pipes or joints. It has good elasticity and heat resistance, and can adapt to various temperatures and pressures.

2. Expansion tape: Expansion tape is a material that can expand to form a sealing layer after contact with water. It is suitable for sealing cracks, crevices and holes and can withstand high pressures.

3. Cement slurry: Cement slurry is a commonly used pressure sealing material, mainly composed of cement and water mixed. The cement slurry has high strength and corrosion resistance and is suitable for sealing large cracks and holes.

4. Polyurethane foam: Polyurethane foam is a material with a high expansion rate and is often used to plug large holes or pipes. It can quickly expand to fill gaps and form a strong sealing layer.

5. Capsule sealer: Capsule sealer is a prepackaged material that usually consists of a capsule and a sealer. Put the capsule into the area to be blocked. After the capsule dissolves, the blocking agent is released to form a sealing layer.

6. Polymer sealer: Polymer sealer is a material that can quickly solidify to form a strong sealing layer. It is suitable for plugging pipes, holes and cracks and can withstand high pressure and high temperature environments.

7. Silicone sealant: Silicone sealant is a material with high temperature stability and corrosion resistance, suitable for sealing high temperature pipelines or equipment. It forms a soft and tight seal that effectively stops leaks.

8. Fatty acid salt plugging agent: Fatty acid salt plugging agent is a material that can form a stable foam in water. It is suitable for plugging cracks and holes in sewage pipes, ponds or swamps.

9. Clay sealer: Clay sealer is a material with good plasticity and water absorption. It is suitable for sealing smaller cracks and holes and is able to effectively hold back moisture.

10. Sealing tape: Sealing tape is a material with good adhesion and high temperature resistance. It is suitable for sealing pipes, joints and interfaces to effectively stop leaks.

These are just some of the common sealing materials with pressure, there are many other types of materials suitable for different sealing needs. When selecting materials, factors such as environmental conditions, material performance and sealing requirements need to be considered to ensure the sealing effect and stability.
