Pipe Tapping Connection Assembly for Compact Opposite Outlets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bypass flanges for tapping tubes onto pipelines under pressure are bulky and expensive, making them impractical for installations with closely spaced or aligned outlets.
Innovation Solution
A connection device comprising a tubular body with a threaded end and a sealing ring that centers and clamps onto the pipeline without surrounding it, using a tilting movement and rotational connection, allowing for compact installation and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bypass flange is used to tap a tube onto a pipeline wall, then the connection is secure and can withstand clamping forces, but the device becomes bulky and expensive, making it impractical for closely spaced or aligned outlets
Solution Approach 1:
The connection device is divided into two separate half-shells that are hinged together, allowing the device to be assembled around the pipe in a compact manner while maintaining structural integrity and sealing capability
Solution Approach 2:
The two half-shells are designed to nest together when closed, with one half-shell containing or interfacing with the other, creating a compact assembled structure that minimizes the overall volume required for the connection device
2Reliability
If a bypass flange is used to tap a tube onto a pipeline wall, then the connection is secure, but the device becomes expensive and bulky, making installation difficult when outlets are aligned or opposite each other
Solution Approach 1:
The bypass flange is segmented into two half-shells that can be independently positioned and assembled, allowing installers to work on opposite sides of the pipe simultaneously and making it feasible to install multiple outlets in aligned or opposite configurations
Solution Approach 2:
The hinged connection between half-shells provides dynamic adjustment capability during installation, allowing the device to adapt to different pipe positions and orientations, thereby facilitating easier installation in various configurations including aligned and opposite outlets

AI summary
The invention relates to a connection device for tapping a tube onto a pipe wall provided with a hole. The device comprises: – a tubular body having a threaded first end portion and a second end portion provided with at least one shoulder extending essentially radially, – a sealing ring which has a frontal surface extending facing the shoulder and which is mounted on the tubular body so as to slide axially along said body between a first position, in which the frontal surface is close to the shoulder, and a second position, in which the frontal surface is spaced apart from the shoulder, the second end portion and the shoulder being arranged so as to be inserted into the hole and the sealing ring being provided with means for centering with respect to said hole, – a connection element delimiting a channel that has one end in which the tube is captive in a sealing manner, the other end being formed so as to be screwed onto the threaded end portion of the tubular body and push the sealing ring into the close position so as to clamp the wall between the frontal surface and the shoulder.
