Pipe Joint Support Structure to Prevent Clamp-Induced Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe member connection structures suffer from poor sealing and waterproofing due to deformation of pipe members under the action of fasteners, leading to ineffective abutment and reduced reliability of line pipe systems.
Innovation Solution
A support member comprising an annular body with a support projection that extends into the pipe member to prevent deformation and ensure effective abutment, combined with a hoop and sealing ring for enhanced sealing and waterproofing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a fastener or clamp is used to connect adjacent line pipes, then the line pipes are fixedly connected, but the line pipes deform under the fastening action resulting in poor sealing and waterproofing
Solution Approach 1:
A foam filling material is introduced as an intermediary substance between adjacent line pipes. This foam material fills the gap and abutment region, providing cushioning and support that prevents pipe deformation while maintaining connection strength, thereby resolving the contradiction between strong fastening and good sealing performance
Solution Approach 2:
The foam filling material is installed beforehand in the gap between adjacent line pipes before the fastening operation. This pre-cushioning approach ensures that when the fastener or clamp applies tightening force, the foam material already provides protective cushioning that prevents deformation and maintains sealing integrity

AI summary
The invention discloses a support member, comprising an annular body and a support projection disposed on an end surface and/or an inner wall of the annular body, wherein the support projection extends from the end surface of the annular body in an axial direction of the annular body and is configured to extend into an interior of a pipe member to support the pipe member. The pipe member is supported so that the pipe member is prevented from deformation under the action of a fastener, and effective and reliable abutting of the adjacent pipe members located on two sides of the support member is ensured, thereby improving the sealing performance and waterproofing performance at the abutment of the adjacent pipe members to enable a line pipe system formed by the pipe member to be more safe and reliable.
