Pipe Fitting Liner Structure for Slurry Erosion Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pipeline systems face premature wear due to the erosion of pipe fittings by solid particles in slurry flows, as the material used for fittings is more susceptible to erosion compared to the material used for pipe segments, leading to a reduced lifespan.
Innovation Solution
Implementing a fitting liner within the pipe fitting that is less susceptible to erosion, made of materials like ceramic or polymer, which is secured between the fitting body and the bore, and can be replaced when worn out, to reduce contact between solid particles and the fitting body.

Engineering Contradiction Analysis
1Strength
If a pipe fitting is made using metal material, then the structural strength and durability are improved, but the susceptibility to erosion by solid particles increases
Solution Approach 1:
The pipe fitting combines metal material for the fitting body (providing structural strength) with a separate liner made of erosion-resistant material such as plastic or ceramic (providing erosion resistance). This composite structure allows each material to perform its optimal function, resolving the contradiction between strength and erosion susceptibility.
Solution Approach 2:
The erosion-resistant liner is applied specifically to the inner surface of the fitting bore where solid particle contact occurs, while the metal fitting body maintains its structural integrity. This localized application of different material properties addresses the erosion issue without compromising overall structural strength.
2Duration of action of stationary object
If the pipe fitting material is more erosion-resistant, then the lifespan is extended, but the cost of material and manufacturing increases
Solution Approach 1:
The pipe fitting is divided into two separate components: the metal fitting body and the erosion-resistant liner. This segmentation allows the expensive erosion-resistant material to be applied only where needed (inner surface), rather than requiring the entire fitting to be made from expensive material, thus reducing overall manufacturing cost while extending lifespan.
Solution Approach 2:
The erosion-resistant liner acts as an intermediary layer between the slurry flow and the metal fitting body. This mediator protects the expensive metal component from direct contact with erosive particles, extending the fitting's lifespan while allowing the use of cost-effective metal materials for the main structure.
3Object-affected harmful factors
If a fitting liner is added to protect against erosion, then the erosion resistance is improved, but the device complexity increases
Solution Approach 1:
The erosion protection function is extracted as a separate removable liner component rather than being integrated into the fitting body itself. This allows the liner to be independently installed, inspected, and replaced without affecting the main fitting structure, thereby managing complexity through functional separation.
Solution Approach 2:
The erosion-resistant liner is designed as a consumable component that can be replaced when worn, while the expensive metal fitting body is retained and reused. This approach manages complexity by allowing selective replacement of only the worn liner rather than replacing the entire fitting assembly.

AI summary
Techniques for implementing and/or operating a pipeline system. The pipeline system includes a pipe segment, in which the pipe segment includes tubing that defines a pipe bore and a fluid conduit in a tubing annulus, and a pipe fitting to be secured to the pipe segment. The pipe fitting includes a fitting body that defines a fitting bore, a fitting jacket implemented circumferentially around the fitting body to define a tubing cavity, in which the tubing of the pipe segment is to be inserted into the tubing cavity and the fitting jacket is to be conformally deformed around the tubing of the pipe segment, and a fitting liner secured in the fitting bore of the pipe fitting such that a body section of the fitting liner is secured directly against the fitting body to facilitate blocking a solid particle in a slurry that flows therethrough from contacting the fitting body.
