- Pipeline Lining Resin System for Leak-Free Joint Sealing
Pressurized fluid expands the resin-coated liner against pipe walls to seal lateral connections and prevent leaks without excavation.
- Resilient Draining Pipe Mesh With Intersection Boxes
A resilient draining pipe mesh uses intersection boxes and access tubes to route fluid flow through multiple parallel paths.
- Air Removing Tool for Gap Filling in Conduit Lining
Segmenting the tool's leading end face prevents filler material from entering before complete air removal, ensuring uniform gap filling.
- Expandable Pipe Grooves for Grout Placement in Conduit Restoration
Radially extending grooves on an expandable pipe liner segment grout material, ensuring controlled placement and complete filling of conduit cracks.
