Liner Pipe Connection Adapter for Leak-Tight Bore Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe connection systems fail to provide a reliable seal and prevent leakage when connecting to multilayer pipes, as the medium can penetrate between the pipe and the liner due to exposed boundary surfaces during drilling.
Innovation Solution
A pipe connection system featuring a flange collar with an intersection curve shape and an anti-rotation device, combined with a flexible pipe connection adapter and elastomeric sheathing, ensures precise alignment and sealing without deformation, using a 2-component injection molding process for secure material bonding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a bore is made through a multilayer pipe wall, then a connection can be established, but the boundary surfaces of the sectioned layers are exposed allowing medium penetration and leakage
Solution Approach 1:
The pipe connection adapter is inserted through the bore from the interior side, with the flange collar nesting against the outer surface of the pipe. The seal element is nested within the adapter structure, creating a hierarchical sealing system that addresses both connection and leakage prevention
Solution Approach 2:
A seal element is introduced as an intermediary component between the pipe connection adapter and the pipe wall. This seal element fills the gap created by the bore and prevents medium penetration between layers while maintaining the connection functionality
2Reliability
If a seal element is used to prevent leakage, then seal tightness is improved, but the seal element must be deformed into a complicated shape matching the bore passage
Solution Approach 1:
The flange collar is pre-formed with the intersection curve shape matching the bore passage geometry. This preliminary shaping allows the seal element to be positioned correctly without requiring complex deformation during installation, as the guiding structure is already in place
Solution Approach 2:
The flange collar acts as an intermediary guiding structure that translates the complex bore passage shape into a manufacturable form. Instead of deforming the seal element into a complicated shape, the flange collar provides the geometric reference that simplifies seal element design and installation
3Strength
If the flange collar is made rigid for structural stability, then structural strength is improved, but it cannot adapt to the non-circular shape of the bore passage
Solution Approach 1:
The flange collar exhibits local quality by having different geometric characteristics in different regions. The outer circumference maintains a standard circular shape for structural stability and manufacturing, while the inner sealing surface is shaped with an intersection curve to adapt to the non-circular bore passage. This localized geometric variation resolves the contradiction between rigidity and adaptability

Function Achieved in This Case
The system effectively prevents medium penetration between pipe layers, ensuring a tight seal and reliable connection by aligning the flange collar with the bore edge, utilizing flexible components that maintain sealing integrity under pressure and shear forces.

AI summary
A system and method of use thereof to produce pipe connections to conduits which have been remediated using a liner. A pipe clamp is attached after a bore has been made and is secured with a clamping strap, for example. A pipe connection adapter with a flange collar and a seal arranged thereon is introduced from the inside of the pipe. An anti-rotation device between the pipe clamp and the pipe connection adapter ensures that the latter assumes a precisely defined position, such that a flange collar, with a shape corresponding to the intersection curve of the conduit/bore, provides a seal on the liner exactly on the edge of the bore. Connection can also be made from the outside of the conduit.
