Split Swivel Ring Pipe Joint for Weld-First Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional swivel ring pipe connections require the swivel ring to be assembled to the pipe before welding the collar, limiting material choices and increasing the risk of distortion due to heat input during welding.
Innovation Solution
A pipe connection swivel joint assembly featuring a split ring assembly with swivel ring halves and an outer ring connected by split ring fasteners, allowing the swivel collar to be integrated seamlessly without pre-assembly, enabling welding without pre-mounting the swivel ring and providing hoop load capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the swivel ring is assembled to the pipe before welding the collar, then the connection stability is ensured, but the material selection is limited and distortion risk increases due to heat input during welding
Solution Approach 1:
The swivel ring is divided into two halves (first swivel ring half and second swivel ring half) that can be separately positioned around the pipe. This segmentation allows the collar to be welded to the pipe first, then the swivel ring halves are assembled around the already-welded collar, enabling welding without pre-assembly and expanding material selection flexibility.

3Ease of manufacture
If the swivel ring is assembled to the pipe before welding the collar, then the assembly process is simplified, but the manufacturing complexity increases due to pre-assembly requirements

This segmentation allows the collar to be welded to the pipe first, then the swivel ring halves are assembled around the already-welded collar, enabling welding without pre-assembly and expanding material selection flexibility.
Solution Approach 2:
The collar acts as an intermediary component that connects the pipe to the swivel ring halves. The collar includes a collar body with an inner surface that receives the pipe and an outer surface that engages with the swivel ring halves, facilitating the welding process without pre-assembly requirements.

AI summary
A pipe connection swivel joint assembly includes a pipe member having an end flange with a conical proximal surface. A split ring assembly includes a pair of swivel ring halves each having a conical inner surface disposed against the conical proximal surface of the pipe member. The pair of swivel ring halves further include a plurality of mounting holes extending axially through the pair of swivel ring halves and a plurality of ring fastening holes. An outer ring is connected to the pair of swivel ring halves by a plurality of split ring fasteners engaged with the plurality of ring fastening holes. The outer ring supports a pair of distance plates that are disposed between opposing ends of the pair of swivel ring halves.
