Pipe Alignment and Centering Tools for Welding
Posted on
When it comes to pipe alignment and centering for welding, precision and efficiency are crucial. Misaligned pipes can cause time-consuming rework, poor weld quality, and unnecessary costs. This is where AMA® Centering Collars make the difference: ultra-fast, accurate, and easy-to-use tools designed to minimize errors in pipe installation and welding.
Why Pipe Alignment Matters
Correct pipe alignment ensures:
- Strong, high-quality welds
- Reduced installation errors
- Faster workflow with fewer interruptions
- Improved safety and ergonomics for welders
Without the right tools, pipe centering can be slow and imprecise, but with AMA Collars, the process becomes both reliable and efficient.
What Are AMA® Centering Collars?
AMA Centering Collars are stainless steel, acid-resistant collars designed to align pipes quickly and precisely. They are available in a wide range of sizes, covering:
- DN dimensions: DN65 – DN1500
- NS dimensions: NS100 – NS1500
- Compatibility: Collars DN/NS 350 and larger fit both DN and NS dimensions
By using a collar tightener, the collar is secured around the pipe, ensuring optimal centering before welding begins. This reduces misalignment and guarantees consistent welding results.

To suit different project needs, AMA offers ready-to-use sets:
- Basic Centering Collar Set (3040)
- DN150–DN500 collar sizes
- Includes a Basic Tightener (3010)
