Pipe Connection Bead Sealing High Pressure Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe connections fail to maintain a secure seal and mechanical stability under high pressure conditions, as they are prone to loosening due to fluid pressure differences between connected pipe sections.
Innovation Solution
A pipe connection design featuring a sealing ring that overlaps the free edge of one pipe end with a bead, supported by a clamping ring and anchor ring, which provides a form-fitting grip and non-positive engagement to prevent detachment, using a U-shaped clamping ring and a toothed anchor ring to secure the second pipe end, and a pipe clamp with half-shells for easy assembly and high-pressure resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rubber seal is used to seal the joint between pipe ends, then the sealing is effective for low-pressure applications, but the sealing fails under high-pressure conditions
Solution Approach 1:
The sealing mechanism changes from elastic deformation (rubber seal) to geometric interlocking (bead overlapping free edge). The bead-shaped sealing ring creates a mechanical lock that resists high pressure through geometric constraint rather than material elasticity, enabling reliable sealing under high-pressure conditions.
2Strength
If a toothed anchor ring is pressed against the pipe end surface to prevent pull-out, then mechanical stability is improved, but the pipe connection becomes prone to loosening under high fluid pressure
Solution Approach 1:
The connection stability function is divided into two independent mechanisms: the bead-shaped sealing ring handles the sealing and high-pressure resistance, while the toothed anchor ring handles the pull-out prevention. This segmentation allows each component to be optimized for its specific function, with the anchor ring teeth designed to dig into the pipe surface for maximum mechanical grip without being compromised by pressure differential.
3Ease of operation
If the pipe clamp is designed to provide a form-fitting grip on the socket-shaped expansion, then assembly ease is improved, but the positioning precision of the pipe ends is compromised
Solution Approach 1:
The bead-shaped sealing ring acts as an intermediary element that provides precise positioning between the first and second pipe ends. It sits in the groove of the first pipe end and engages with the second pipe end, ensuring accurate alignment and positioning while allowing the pipe clamp to simply apply clamping force without requiring complex form-fitting geometries.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design ensures reliable sealing and mechanical stability against high pressures, allowing for precise positioning and secure connection of pipe ends, preventing loosening and maintaining integrity under high-pressure loads.
Implementation Method 1
a sealing ring (13) which seals the space between the pipe ends (1, 6)
Implementation Method 2
the anchor ring (9) is designed in such a way that, when the pipe clamp (14) is tensioned, its toothed inner edge (11) presses against the surface of the second pipe end (6)
Implementation Method 3
a tensionable pipe clamp (14) in which a toothed anchor ring (9) is mounted, which, when the pipe clamp is tightened, presses its toothed inside against the surface of the second pipe end (6)

AI summary
The pipe connection has two pipe ends (1,6), where the former pipe end is expanded in a socket-shaped manner such that the latter pipe end is inserted into an expansion (2). A pipe clamp (14) is provided with an inner contour. The socket-shaped expansion of the former pipe end overlaps against an extract direction (A1) for releasing the pipe ends from each other.
