Expansion packer is an industrial tool designed for rapid sealing of holes, widely used in mining, construction, pipeline maintenance, underground engineering and other fields. Rapid expansion upon contact with water or pressure, forming a high-strength sealing layer that effectively isolates gas and liquid leakage, ensuring construction safety and efficiency. Applicable scenarios Sealing of gas extraction holes in mining tunnels, temporary sealing of grouting holes in underground engineering, emergency repair and plugging of pipelines Temporary protection for cracks in concrete structures Other industrial scenarios that require fast and reliable sealing of holes。Sealing diameter: 56-120mm (can be customized according to requirements) Work pressure: 1-40Mpa Sealing depth: 2m-50m Rubber expansion coefficient: 80%。
