Pipeline Pig Wrap and Wash for Contamination Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pipeline pigs often carry contaminants from the pipeline, leading to environmental and product contamination during handling and storage, necessitating effective containment solutions.
Innovation Solution
A pipeline pig wrap with an elongated non-permeable wrap and a holding ring, along with a locking mechanism, is used to encase and transport pigs, while a pipeline pig wash with a cleaning chamber, support, and collection tray ensures thorough cleaning and containment of contaminants.

Engineering Contradiction Analysis
1Productivity
If pipeline pigs are handled and stored after use, then they can be reused for cleaning and inspecting pipelines, but they carry product contaminants that can contaminate the surrounding area and subsequent pipeline products
Solution Approach 1:
A non-permeable wrap serves as an intermediary barrier between the contaminated pipeline pig and the surrounding environment. The wrap encapsulates the pig, preventing direct contact between contaminants and the external environment while allowing the pig to be transported and stored for future reuse.
Solution Approach 2:
The contaminated product is effectively extracted or isolated from the pipeline pig by enclosing it within the non-permeable wrap. This separation removes the harmful contaminants from potential contact with the surrounding area and subsequent products, enabling safe handling and storage.
2Object-affected harmful factors
If pipeline pigs are cleaned between uses, then contamination is reduced, but the cleaning process requires additional equipment and time
Solution Approach 1:
The non-permeable wrap is applied to the pipeline pig before it leaves the pipeline, performing a preliminary containment action. This prevents contamination from spreading in the first place, eliminating or reducing the need for subsequent cleaning operations and associated equipment.
3Productivity
If pipeline pigs are stored after use, then they are available for future use, but they may contaminate subsequent pipeline products
Solution Approach 1:
The non-permeable wrap acts as a protective intermediary during storage, maintaining isolation between the contaminated pig and the environment. This ensures that even during extended storage periods, contaminants cannot escape to affect subsequent pipeline products when the pig is deployed again.

AI summary
A pig wrap has an elongated non-permeable wrap and a holding ring. The elongated non-permeable wrap has a first end that is closed and a second end that is attached to the holding ring. The holding ring retains the elongated non-permeable wrap in such a manner that the elongated non-permeable wrap is capable of encompassing a pipeline pig as it passes through the holding ring. The holding ring is positionable at an exit of a pig trap or launcher.
