Tubular Pipe Junction Ring for Chamfer-Free On-Site Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing junction systems for tubular fluid distribution elements require complex and costly equipment for processing pipes, especially when chamfers need to be created on site, which can be dangerous and time-consuming.
Innovation Solution
A junction system that uses a ring with a truncated conical protrusion and a radial appendix to create a chamfered effect without the need for on-site machining, allowing for quick and safe assembly of tubular elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If pipes are cut on site to reduce length, then the required pipe length is achieved, but the chamfered edge is lost and complex machining equipment is required
Solution Approach 1:
The chamfer is pre-formed on the pipe during factory manufacturing before shipment. This preliminary action ensures that when pipes are cut on-site to required lengths, the chamfer remains intact and no additional machining equipment is needed at the installation site.
Solution Approach 2:
The chamfering operation is extracted from the on-site installation process and moved to the factory manufacturing process. This separation eliminates the need for complex portable machining equipment at construction sites while still providing the necessary chamfered edges for proper gasket engagement.
2Manufacturing precision
If chamfering is performed on site using turning, grinding or filing equipment, then the pipe edge is properly prepared, but processing time increases and operator safety risks increase
Solution Approach 1:
The precise chamfering operation is performed at the factory using precision machining equipment before the pipe is shipped. This preliminary precision work eliminates the need for time-consuming on-site chamfering operations while maintaining high edge preparation quality for proper gasket engagement.
Solution Approach 2:
The pipe is supplied with a pre-formed chamfer that is sufficient for its intended use. This disposable pre-processing approach eliminates the need for expensive, time-consuming on-site machining operations while achieving the required edge preparation quality.
3Manufacturing precision
If chamfering equipment is used on site, then proper edge preparation is achieved, but operator safety risks and equipment cost increase
Solution Approach 1:
The hazardous on-site chamfering operation is extracted and relocated to the factory environment where it can be performed with proper safety controls. This eliminates the need for operators to work with dangerous rotating machinery or abrasive tools at construction sites while maintaining precise edge preparation quality.
Solution Approach 2:
The potentially hazardous chamfering operation is performed in advance at the factory under controlled conditions. This preliminary action removes the safety risks associated with on-site machining equipment while ensuring proper edge preparation is achieved before the pipe reaches the installation site.

AI summary
Integrated junction system for tubular fluid distribution elements including a tubular element which has, at a first end an enlarged cup shape whose base determines the formation of an annular shoulder inside the tubular element, a ring with a suitably shaped section, which is associated with a second end of the tubular element equipped with a truncated conical or other conveniently shaped protrusion, which abuts on the edge of this second end and with a radial appendix which is associated with the radial end of the tubular element, wherein the system in order to join two tubular elements of the same type, provides that the second end of the tubular element equipped with the ring is inserted into the first end having an enlarged cup shape of the second tubular element until the protrusion of the ring comes into contact with the annular shoulder formed inside the tubular element.
