Manual Pipe Flange Alignment Tool is a specialized fixture designed for accurate pipe-to-flange fit-up and welding. Featuring a precision mechanical structure, it improves alignment accuracy, reduces installation time, and increases welding efficiency. It provides stable and reliable positioning, making it an ideal solution for pipeline fabrication and flange welding applications.
WhatsApp: 8615515833787 WeChat: 15515833787Manual Drive System – Equipped with a handwheel, lead screw, and locking mechanism for smooth, precise operation without external power.
Scissor Expansion Mechanism – Precision X-shaped stainless steel linkages convert screw movement into uniform radial expansion for stable internal positioning.
Expansion Support Blocks – Evenly grip the pipe's inner wall, automatically centering the pipe and correcting out-of-roundness.
Flange Positioning Reference – Uses the flange face as the alignment reference to ensure accurate concentricity and parallel alignment before welding.
By turning the handwheel, the lead screw drives the scissor mechanism outward, allowing the support blocks to expand evenly against the pipe's inner wall. This automatically centers the pipe, corrects ovality, and ensures precise pipe-to-flange alignment with no misalignment, providing a stable and reliable fit-up for high-quality welding.
High-Precision Alignment – Achieves exceptional fit-up accuracy with ≤1 mm mismatch and ≤0.5 mm concentricity, meeting the strict requirements of high-pressure pipelines and precision welding projects.
All Stainless Steel Construction – Made from corrosion-resistant stainless steel, ideal for hygienic applications in food, pharmaceutical, chemical, and stainless steel piping systems.
Portable Manual Operation – Fully mechanical design with no need for power or air supply. Compact and easy to operate, even in remote or emergency repair environments.
No Welding Obstruction – Internal expansion design keeps the root weld area fully accessible, ensuring continuous welding and preventing deformation caused by external alignment tools.
Wide Application Range – Standard models support DN50–DN600 pipes and are compatible with various pipe and flange sizes for versatile industrial applications.

Ideal for flange fit-up and welding in oil & gas, chemical, gas, water supply, and industrial piping systems.
Model selection support: Based on pipe diameter and wall thickness, we quickly recommend the suitable TPS series pipe scraper to ensure proper compatibility.
Suitable for stainless steel and clean piping applications requiring high-precision welding.
Perfect for field repairs and installation in power-free environments with fast and flexible operation.
Widely used for flange welding and alignment of pressure vessels and equipment connections.
Maintenance guidance: We provide instructions for daily maintenance, blade cleaning, and troubleshooting to extend equipment service life.
Before Use: Clean pipe interiors and flange surfaces, and check moving parts such as linkages and lead screws for proper operation.
Expansion Operation: Turn the handwheel smoothly and evenly to ensure balanced clamping without damaging the pipe or flange.
Tool Removal: Remove the tool only after root welding is completed and the weld has cooled to prevent deformation.
Regular Maintenance: Clean and lubricate the lead screw and linkages after use, and inspect fasteners regularly to extend service life.
