Solution Overview
Problem
Conventional test tools for tubular components primarily assess pressure integrity but fail to provide a comprehensive evaluation of the strength capability of the components or their welds.
Innovation Solution
A method and tool that apply both test pressure and axial load to the tubular component, allowing for simultaneous or sequential monitoring of strength and integrity testing, utilizing engaging elements and a force-generating arrangement to apply an axial force, while also incorporating seal elements for leak testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional pressure testing tools are used to test tubular components, then pressure integrity can be assessed, but strength capability cannot be evaluated
Solution Approach 1:
The test tool is designed to perform multiple functions: it can apply radial pressure to test pressure integrity, apply axial loads to test strength capability, and monitor both pressure and load simultaneously. This multi-functional design allows a single tool to assess both pressure integrity and strength capability of tubular components and their welds.
2Strength
If axial load is applied to the tubular component during testing, then strength assessment is enabled, but test complexity increases
Solution Approach 1:
The invention combines the pressure application mechanism and axial load application mechanism into a single integrated test tool. The tool includes both a pressure source for radial loading and a force-generating arrangement for axial loading, allowing both types of testing to be performed simultaneously or sequentially without requiring separate testing equipment.
Solution Approach 2:
The test tool acts as an intermediary device that applies controlled axial loads through engaging elements that contact the tubular component. The force-generating arrangement produces axial force that is transmitted through the engaging elements to the component being tested, enabling strength assessment without direct manual application of load.
3Measurement precision
If engaging elements are used to apply axial force, then localized strength testing is improved, but device complexity increases
Solution Approach 1:
The test tool is divided into distinct functional segments: a body portion, engaging elements for contact with the tubular component, and a force-generating arrangement. This segmentation allows each component to perform its specific function efficiently while maintaining overall system manageability and reducing complexity through modular design.

Data Source
AI summary
A test tool for use in testing a tubular component such as a pipe includes a body having first and second body portions together defining a sliding sleeve. Axially spaced sealing and gripping modules are provided, with one module located on the first body portion and another module located on the second body portion. A force-generating arrangement is provided to apply an axial test force to the tubular component via the modules. A test pressure is applied to a section of the wall of the tubular component and an axial load is applied to the wall section. Application of the axial load between the first and second modules applies the axial load to the wall section of the tubular component to facilitate strength testing of the tubular component.
