Outlet Pipe Wear Module for Corrosion and Erosion Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial outlet pipes used in high-pressure fluid processes, such as mineral processing, face significant corrosion and wear due to the harsh conditions, leading to frequent replacements and increased operational costs.
Innovation Solution
The integration of a wear module within the outlet pipe design, which directs the majority of wear and corrosion to a replaceable component, thereby extending the replacement intervals of the structural parts and reducing maintenance costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the outlet pipe is made with high corrosion and wear resistance materials, then the reliability and lifespan of the pipe is improved, but the manufacturing cost and complexity increase
Solution Approach 1:
The outlet pipe is divided into two functional segments: a structural discharge pipe made of cost-effective material and a wear module made of wear-resistant material. This segmentation allows each component to be optimized independently, reducing overall manufacturing complexity while maintaining reliability.
Solution Approach 2:
Instead of making the entire outlet pipe from expensive wear-resistant material, the wear-resistant properties are localized to the wear module that directly contacts the erosive fluid. The structural discharge pipe can use cheaper materials, reducing manufacturing cost and complexity while maintaining where needed.
2Productivity
If the structural parts are designed for long replacement intervals, then the operational cost is reduced, but the initial manufacturing cost increases
Solution Approach 1:
The wear module is designed as a disposable or easily replaceable component that absorbs wear and corrosion, allowing the expensive structural discharge pipe to remain in service for longer periods. This reduces operational downtime and replacement costs while keeping initial manufacturing costs manageable.
Solution Approach 2:
The wear-resistant functionality is extracted from the structural discharge pipe and placed into a separate wear module. This allows the structural pipe to be manufactured more simply and cheaply, while the wear module can be optimized for longevity without increasing overall manufacturing cost.
3Reliability
If frequent maintenance and replacement is performed, then the reliability of the system is maintained, but the operational cost and downtime increase
Solution Approach 1:
By segmenting the outlet pipe into a structural discharge pipe and a replaceable wear module, maintenance can be focused on only the wear module when wear occurs. This reduces maintenance downtime significantly compared to replacing the entire outlet pipe assembly, while maintaining system reliability.
Solution Approach 2:
The wear module is pre-designed and pre-positioned in the outlet pipe during manufacturing. This preliminary action ensures that when wear occurs, only the pre-configured wear module needs to be replaced, reducing maintenance complexity and downtime while maintaining system reliability.

AI summary
An outlet pipe includes a discharge pipe having an inlet end for receiving fluid and an outlet end for passing fluid, a connector attached to the discharge pipe to cover the inlet end, and a wear module arranged in a cavity limited by the discharge pipe and the connector. The connector has an interface surface for attachment to an outlet face of a valve providing the fluid, and the wear module has a conduit so that at least the discharge pipe and the conduit mutually define a flow channel passing fluid from the interface surface to the outlet end.
