Branch Pipe Fitting Holder for Perpendicular Welding Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for attaching branch pipes to pipelines result in non-uniform weld seams due to improper alignment, and require bulky devices or individual mounts for each diameter, limiting versatility.
Innovation Solution
A fitting holder with a hollow-cylindrical housing and a displaceable ring, featuring adjustable inside diameters and spring-loaded mounts, ensures perpendicular attachment of differently sized branch pipes, using clamping elements to guide and fix the branch pipes concentrically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a bore is used to guide the branch pipe during welding, then the branch pipe can be attached to the pipeline, but the weld seam becomes non-uniform due to improper alignment
Solution Approach 1:
The fitting holder features a guide section with a guide diameter that matches the outer diameter of the branch pipe, creating a localized precise guidance zone. This guide section is positioned at a specific location within the holder to ensure the branch pipe is guided perpendicularly to the pipeline axis during insertion, thereby achieving uniform alignment without complicating the overall device structure.
2Adaptability or versatility
If individual mounts are provided for every diameter of the outlet stub, then each diameter can be welded perpendicularly, but the device becomes bulky and lacks versatility
Solution Approach 1:
The fitting holder is designed with a guide section having a guide diameter that corresponds to the outer diameter of the branch pipe, allowing a single holder design to accommodate multiple branch pipe diameters. The guide section provides universal guidance functionality, eliminating the need for multiple specialized mounts for different outlet stub diameters while maintaining perpendicular welding capability across various sizes.
3Manufacturing precision
If the branch pipe is guided exclusively by the bore, then the device structure is simple, but the guide surface is too short resulting in oblique welding
Solution Approach 1:
The fitting holder incorporates a dedicated guide section as a distinct segment within the overall structure. This guide section has a specific length that is sufficient to guide the branch pipe perpendicularly, separating the guidance function from other functions of the holder. The guide section's length is optimized to provide adequate guidance surface without making the entire device excessively long.

AI summary
A fitting holder designed for receiving a branch pipe during a welding operation in order to attach the branch pipe to a pipeline or a pipe, wherein differently dimensioned branch pipes can be received by the fitting holder, comprising a hollow-cylindrical housing with an upper region which, during the welding, faces away from the pipeline to be welded thereto, and a lower region which, during the welding, faces the pipeline to be welded thereto, wherein mounts for the axial fixing of the branch pipe which can be received by the fitting holder are arranged in the lower region, a ring arranged displaceably in the housing, and clamping elements pressing the ring downwards, wherein the fitting holder has different guide inside diameters which guide the differently dimensioned branch pipes by way of their differently dimensioned outside diameters in the fitting holder.
