Universal Thread Protector for Pipe Ends
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional thread protectors for pipes require numerous specialized designs to accommodate different pipe diameters and thread forms, leading to significant manufacturing and storage challenges, as well as time-consuming installation and removal processes.
Innovation Solution
A universal thread protector with a cap, seal element, and radially disposed bolts that can fit both pin and box ends of pipes, using a deformable seal element and ring member to create a secure seal without threading, allowing for quick and secure attachment without the need for screwing or unscrewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional specialized thread protectors are used for different pipe diameters and thread forms, then protection reliability is improved, but device complexity and quantity increase significantly
Solution Approach 1:
The patent applies universality by designing a single thread protector structure that can accommodate multiple pipe diameters and thread forms through adjustable components. The protector includes a body with an adjustable sealing element and threading mechanism that can be configured to match different pipe specifications, eliminating the need for numerous specialized protector types while maintaining protection reliability.
Solution Approach 2:
The patent applies dynamics by incorporating adjustable and movable components within the thread protector. The sealing element can be positioned at different locations, and the threading mechanism can be adjusted to engage with various thread pitches and geometries. This dynamic adaptability allows one protector design to serve multiple protection needs across different pipe configurations.
2Reliability
If conventional threaded installation methods are used, then secure attachment is achieved, but installation and removal time increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring the threading mechanism and sealing elements within the protector body before installation. The protector is designed with pre-formed threads and positioning features that align with standard pipe thread patterns, allowing for rapid engagement without requiring complex alignment or multiple adjustment steps during the installation process.
Solution Approach 2:
The patent applies inversion by reversing the traditional threading approach. Instead of requiring the protector to be threaded onto the pipe in a time-consuming manner, the design allows the pipe to be inserted into the protector body, where the threading mechanism then engages and secures the connection. This inverted approach simplifies the initial installation action while maintaining secure attachment.
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 universal thread protector effectively protects both pin and box ends of pipes from damage and corrosion, reducing the need for multiple specialized protectors and simplifying installation, while ensuring a secure and durable connection.
Implementation Method 1
deforming a rubber seal element positioned interior of the cap so as to create a seal between the cap and the threaded end of the pipe

AI summary
A universal thread protector is provided for protecting either of the pin and box ends of a pipe. The thread protector has a cap with an open end the closed end. A seal element is positioned within and adjacent to the open end of the cap. A ring member is positioned against the seal element between the seal element and the closed end of the cap. Bolts are provided having an end positioned against the ring member. The bolts are movable from an unactuated position to an actuated position wherein the bolt applies a force against the ring member when in the actuated position. As such, the ring member pushes against the seal element so as to deform or compress the seal element against the outer diameter of the pipe positioned within the cap. A method of protecting the threaded ends of pipe is also disclosed.
