Angled Collar Pipe Joints for Angular Displacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe joint technologies lack the ability to easily achieve small angular displacements between pipe sections, making it difficult to adjust and align pipes during installation, and do not allow for effective angular adjustments post-assembly.
Innovation Solution
The pipe joint design features collars formed at an angle deviating from the perpendicular plane, allowing for angular displacement by rotating the pipe sections, and a flange part arrangement with a centering surface to facilitate alignment and secure the joint, enabling small angular adjustments during installation and improving joint quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If collars are formed perpendicular to the pipe axis using conventional methods, then the joint structure is simple and easy to manufacture, but small angular displacements cannot be achieved in the joint
Solution Approach 1:
The collar formation process is modified by changing the shaping angle parameter from perpendicular (90 degrees) to an inclined angle (e.g., 5-10 degrees relative to perpendicular). This parameter change enables the collar surface to provide angular displacement capability while maintaining the basic collar structure and formation process.
Solution Approach 2:
The collar is pre-formed with an inclined angle during the pipe manufacturing or pre-assembly stage, before the actual joint assembly. This preliminary angular preparation allows for easy adjustment and alignment during installation without requiring complex adjustment mechanisms during assembly.
2Ease of operation
If collars are formed at an inclined angle to enable angular displacement, then small angular adjustments can be made during installation, but the collar formation process becomes more complex
Solution Approach 1:
The shaping means is configured with a predetermined inclined angle (e.g., 5-10 degrees) that can be easily incorporated into standard pipe forming equipment. This parameter modification allows conventional manufacturing processes to produce inclined collars without significant complexity increases.
Solution Approach 2:
The collar formation process is divided into two stages: initial collar formation followed by optional angle adjustment. This segmentation allows the basic collar structure to be formed using standard processes, with the inclined angle applied as a separate, simplified step.
3Adaptability or versatility
If flange parts are arranged to be adaptable against the collar shoulder, then straight pipe joints are effectively formed, but angular displacements cannot be accommodated
Solution Approach 1:
The collar is designed with an asymmetric inclined angle relative to the pipe axis, creating a ramp-like surface. The flange part is correspondingly designed to engage with this inclined surface, allowing the joint to accommodate angular displacements while maintaining precise alignment through the asymmetric geometry.
Solution Approach 2:
The inclined collar surface acts as an intermediary element between the pipe axis and the flange part. This intermediate inclined surface enables angular displacement by providing a gradual transition surface that guides the flange into proper alignment while accommodating the angular adjustment.

AI summary
Pipe joint, which is formed from the end portions of the pipe sections (1, 2) to be joined together, said end portions having a collar (3, 4), and from flange parts (9, 10) which, as seen from the junction, are placed on different sides of the collars and tightened with applicable fixing means, such as with screws (17) and nuts (18), which collar (3, 4) of the pipe section is formed from the wall of the end of the pipe section by shaping with shaping means (F). The joint surface (7, 8) of the collar (3, 4) of at least one of the pipe sections (1, 2) to be joined is arranged to be divergent by the amount of an angle (α, β) from the plane perpendicular to the longitudinal axis (L) of the pipe section. The invention also relates to a method and to a flange part arrangement.
