Reusable Pipe Tester Connector for Pressure Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for pressure testing pipes in multi-story buildings are costly due to the permanent installation of test tees, which are not reusable and require extensive use of expansion fittings, leading to high expenses and inefficiencies.
Innovation Solution
A pipe tester connector system comprising a rigid cylindrical member with a flexible cup and sleeve design, allowing for easy installation and removal, and a hose bibb attachment unit for fluid communication, enabling reusable and cost-effective pressure testing without the need for permanent fixtures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If test tees are permanently installed in pipes for pressure testing, then the pipe testing function is achieved, but the installation cost increases and the test tees cannot be reused
Solution Approach 1:
The device segments the pipe testing system into a removable connector assembly that can be detached and reused, rather than permanently installing test tees. The connector separates into components including a rigid cylindrical member, flexible cup member, and attachment unit that can be stored and reused for multiple testing operations.
Solution Approach 2:
The invention recovers and reuses the testing connector after each pressure test, rather than discarding permanent test tees. The connector is removed from the pipe after testing, allowing it to be transported and reused for subsequent testing operations, thereby reducing material costs.
2Reliability
If test tees are permanently installed in pipes, then the pipe testing function is achieved, but the device cannot be reused
Solution Approach 1:
The connector incorporates dynamic elements including a flexible cup member with a flexible sleeve that can expand and contract, and a rigid cylindrical member that can be inserted and removed from the pipe. This dynamic design enables the device to be reused for multiple testing operations while maintaining a secure seal during each test.
3Stability of the object's composition
If expansion fittings are extensively used in multi-story buildings, then the pipe expansion and contraction is accommodated, but the installation complexity and cost increase
Solution Approach 1:
The connector uses a flexible cup member with a flexible sleeve that can accommodate pipe expansion and contraction movements. The flexible material allows the connector to adapt to dimensional changes in the pipe without requiring multiple rigid expansion fittings, thereby simplifying the installation process.
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 system allows for efficient and reusable pressure testing of pipes, reducing installation costs and enabling multiple uses, while maintaining the integrity of the piping system during normal operation.
Implementation Method 1
The first flexible sleeve has a first position in which the first flexible sleeve is folded back onto the rigid cylindrical member and a second position in which the first flexible sleeve is unfolded so as to envelope an end portion of the first pipe
Implementation Method 2
A first hose clamp is disposed about the first flexible sleeve and is configured to secure the first flexible sleeve to the first pipe
Implementation Method 3
The hose bibb attachment unit selectively places the interior region of the first pipe in fluid communication with the testing unit

AI summary
A pipe tester connector includes rigid cylindrical member. The rigid cylindrical member defines a first side hole. A continuous flexible cup member includes circular floor portion and a central tubular portion extending upwardly therefrom. A first flexible sleeve extends from the top of the flexible cup. The first flexible sleeve has a folded down first position and a folded up second position, in which it envelopes the end of the first pipe. A first hose clamp secures the flexible sleeve to the pipe. An attachment unit includes a rigid insert, an attachment pipe, a first adapter and an attachment. The rigid insert is disposed against the tubular portion of the interior surface of the flexible cup. The rigid insert defines a hole in alignment with the first side hole and the second side hole, through which the attachment pipe passes. An adapter is affixed to the attachment pipe.
