RFID Tag Ring for Oil Pipe Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for attaching identification tags to oil production pipes and tubing with low wall thickness are either not feasible due to structural limitations or are not durable enough for harsh environments, as they require drilling or printing, which can weaken the pipes or wear off easily.
Innovation Solution
A metal ring with an integrated RFID tag and galvanic anode is shrunk-fit around the pipe or tubing, providing a secure and corrosion-resistant mounting solution, with options for threaded or drilled installation and additional protection from corrosion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If drilling a slot or hole in the pipe to attach an ID marker, then the ID marker can be securely attached, but the pipe structure is weakened which is not acceptable for low wall thickness pipes
Solution Approach 1:
The solution separates the ID marker attachment function from the pipe structure itself by introducing an independent metal ring component. The ring is fitted around the pipe and secured separately, allowing the ID marker to be mounted on the ring rather than requiring direct attachment to or drilling of the pipe. This segmentation preserves pipe integrity while achieving secure marker attachment.
2Ease of manufacture
If printing an identification number on the pipe, then no structural modification is needed, but the paint is easily worn off in harsh environments
Solution Approach 1:
The metal ring acts as an intermediary carrier for the ID marker, separating the identification function from the pipe surface. Instead of applying paint directly to the pipe where it is exposed to wear, the ID marker is placed on the ring which can be positioned optimally and protected. This intermediary structure solves both the ease of application and durability requirements.
3Reliability
If using a collar fitted around the pipe and tightened by screwing, then the ID marker can be attached, but the device complexity increases
Solution Approach 1:
The metal ring utilizes thermal expansion parameters to achieve attachment. The ring is heated to expand its diameter, fitted around the pipe, and then allowed to cool and contract, creating a secure interference fit. This thermal parameter change provides a simple yet reliable attachment method without requiring complex screwing or welding mechanisms.
