Solution Overview
Problem
Conventional boring processes for gas pipes face high risks of gas leakage during branching operations, particularly with high-pressure gas flows, posing safety threats to workers.
Innovation Solution
A specials tube with an embedded boring tap and a corresponding boring apparatus that adjusts separation and coupling, featuring a threaded connection system and a stopper for sealing, along with a control member and connecting member for forming and sealing the boring hole, reduces leakage by ensuring a secure and controlled boring process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional boring process is used for branching gas pipes, then branching operation can be performed, but gas leakage occurs during the process
Solution Approach 1:
The patent applies preliminary action by pre-installing a sealing member (stopper) in the specials tube before the boring operation begins. This stopper seals the internal passage of the specials tube, preventing gas from leaking during the subsequent boring process. The sealing action is performed in advance, before the harmful effect (gas leakage) could occur.
Solution Approach 2:
The patent segments the boring system into distinct functional components: the specials tube with embedded boring tap, the sealing member (stopper), and the boring apparatus. This segmentation allows the sealing function to be independently controlled and activated at appropriate stages, enabling branching operations while preventing gas leakage through coordinated action of separate components.
2Productivity
If sealing process is performed after boring in conventional method, then branching can be completed, but worker safety is threatened due to gas leakage risk
Solution Approach 1:
The patent reverses the conventional sequence by performing the sealing action before the boring operation. The stopper is pre-installed in the specials tube to seal the passage before the boring tap creates an opening in the main pipe. This preliminary sealing prevents gas leakage during boring, protecting worker safety while maintaining productivity.
Solution Approach 2:
The patent applies preliminary anti-action by installing a sealing member that counteracts the potential harmful effect (gas leakage) before the boring operation creates the condition for leakage. The stopper is positioned in advance to prevent gas from escaping during the subsequent boring process, neutralizing the safety hazard before it can manifest.
3Productivity
If high-pressure gas flows in main pipe, then gas transport efficiency is maintained, but safety of workers is greatly threatened in case of gas leakage
Solution Approach 1:
The patent maintains high-pressure gas flow efficiency while protecting worker safety by pre-installing a sealing member in the specials tube. The stopper is positioned before the boring operation to seal the passage, preventing gas leakage even under high pressure. This allows the system to maintain efficient gas transport while eliminating the safety hazard during branching operations.
4Reliability
If boring tap is embedded in specials tube, then gas leakage is prevented during boring, but device complexity increases
Solution Approach 1:
The patent merges the boring tap with the specials tube by embedding the boring tap directly into the specials tube structure. This integration allows the sealing member to be positioned and secured within the specials tube in a predetermined location, simplifying the overall assembly while maintaining reliable gas leakage prevention during the boring operation.

Function Achieved in This Case
The solution effectively prevents gas leakage during boring operations, enhancing worker safety and allowing for larger diameter boring holes, reducing construction time and labor costs while enabling safer and more efficient branching operations.
Implementation Method 1
an inner circumferential surface of the fixing end and an outer circumferential surface of the boring tap may each be threaded and screw-coupled with each other
Implementation Method 2
a stopper detachably coupled to the other end of the main pipe... and the stopper may seal the other end of the main pipe

AI summary
Provided are a boring apparatus of a specials tube and a boring method using the same. The specials tube for connecting a primary pipe and another pipe includes a main pipe having one end coupled to an outer surface of the primary pipe and having a length formed outside of the primary pipe in a diameter direction, a branch pipe branched from the main pipe, and a boring tap disposed at the other end of the main pipe, wherein a boring hole is formed on an outer surface of the main pipe by adjusting the boring tap in a state where the main pipe is sealed, whereby leakage of a fluid flowing in the primary pipe to the outside may be prevented during a branching operation of a pipe.
