Modular Pipe Passage Flange for Fireproof Watertight Bulkheads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current deck and bulkhead pipe passage systems for boats are invasive, costly, and difficult to install, especially on existing vessels, due to their large size and structural modifications required, which affects space utilization and structural integrity, and lack simultaneous fireproof and watertight certifications.
Innovation Solution
A modular double flange device with graphite gaskets and thermo-expanding tape, allowing for adaptable and non-invasive installation, ensuring fireproof and watertight characteristics up to 10 meters underwater, and accommodating pipe movement and vibration without compromising resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional flange and semi-flange systems are used for pipe passages, then fireproof characteristics are achieved, but the overall dimensions become excessive and space is encumbered
Solution Approach 1:
The passage system is divided into modular components including a first passage element, a second passage element, and a connection element that can be assembled separately and connected together, allowing for compact installation while maintaining fireproof characteristics through the modular design
Solution Approach 2:
The connection element is received within a receiving space defined by the first and second passage elements, creating a nested configuration where components fit within each other to minimize overall dimensions while preserving fireproof sealing capabilities
2Strength
If welding is used to fix passages directly on walls and pipes, then structural attachment is achieved, but resistance characteristics and solidity are reduced due to fatigue
Solution Approach 1:
A connection element acts as an intermediary component between the first and second passage elements, providing a non-welded mechanical connection that avoids direct welding to the pipe or wall, thereby preserving the structural integrity and fatigue life of the original components
3Reliability
If large-sized passage systems are installed, then fireproof certification is achieved, but installation becomes difficult and costly on existing vessels requiring structural changes
Solution Approach 1:
The system is segmented into separate passage elements and connection elements that can be manufactured independently and assembled on-site, eliminating the need for extensive structural modifications to existing vessels and reducing installation complexity and cost
Solution Approach 2:
The connection element provides adjustability in positioning and orientation, allowing the passage system to be installed in various configurations and dimensions to fit different available spaces on existing vessels without requiring major structural changes
4Adaptability or versatility
If traditional passage systems are used, then pipe routing is achieved, but lateral pipe deflection is difficult and space for other purposes is encumbered
Solution Approach 1:
The connection element allows for adjustable positioning and lateral deflection of pipes by enabling relative movement and repositioning of the passage elements, providing operational flexibility without encumbering space for other vessel functions
