Coiled Pipe Transport and Straightening for On-Site Length Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe transport systems face challenges in handling long lengths of work-hardened stainless steel pipes, as welding these pipes alters material properties and makes maintenance of screw connections complex, while existing solutions for unwinding and transporting pipes do not fully address the need for automated processing and selectable pipe lengths.
Innovation Solution
A transport system comprising a coiled receptacle, a drive, a straightening device, and a cutting device, allowing for the automatic unwinding, straightening, and cutting of pipes to any desired length, integrated within a transport container that can be transported and processed at the customer's site, enabling the production of pipe sections with specified lengths and quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If pipes are delivered in maximum lengths that can be stretched out and transported on a truck (around 12 meters), then transportability is improved, but the ability to install significantly longer pipelines without multiple connections is worsened
Solution Approach 1:
The pipe is supplied in coiled form and divided into required lengths at the construction site using the cutting device, eliminating the need for multiple separate pipe sections and connections while maintaining transportability of the coiled form
Solution Approach 2:
The pipe is transported in a coiled configuration (changing from linear to spiral dimension), allowing much longer pipe lengths to fit within standard truck transport dimensions, then straightened and cut to required lengths at the destination
2Length of moving object
If welding is used to join pipe sections, then pipeline length can be extended, but material properties at the weld point are altered
Solution Approach 1:
The pipe is supplied in continuous coiled form with predetermined material properties, and the required length is cut before installation, eliminating the need for welding and preserving the cold-worked material properties throughout the pipeline
Solution Approach 2:
The welding process is completely removed from the pipeline installation process by supplying pipe in coiled form that can be cut to length and joined by mechanical means, extracting the harmful welding step from the system
3Stability of the object's composition
If bolting is used to join pipe sections, then pipeline length can be extended without material changes, but maintenance of connections becomes difficult or impossible when buried underground
Solution Approach 1:
The pipe is supplied in continuous coiled form and cut to the exact required length before installation, eliminating the need for field connections and thereby eliminating maintenance issues associated with buried connections
Solution Approach 2:
All field connections (bolting or welding) are removed from the installation process by supplying pipe in coiled form that can be cut to length, extracting the connection step that causes maintenance problems
4Adaptability or versatility
If pipes are supplied in coiled form, then transportability and flexibility are improved, but the pipes require straightening and cutting to meet customer requirements
Solution Approach 1:
The transport system is merged with processing functions by integrating the straightening device and cutting device directly onto the transport platform, allowing coiled pipe delivery with on-site processing capabilities
Solution Approach 2:
The transport platform serves multiple functions: transporting the coiled pipe, unwinding it, straightening it, cutting it to length, and delivering the finished pipe sections, creating a universal system that handles both transport and processing
