At GYGV Kanizsa, we use advanced pipe collaring technology (also known as neck forming) to manufacture stainless steel manifolds for various industrial applications.
This process allows us to create accurate, leak-proof branch connections on main pipes without full-penetration welding, enhancing the mechanical strength, hygiene, and durability of the assemblies.
Why is pipe collaring technology advantageous?
- No full-penetration weld seam → no dead spots or unfavorable turbulence
- Hygienic surface, ideal for food and pharmaceutical systems
- Additional connections can be welded with orbital tube welding
- High dimensional accuracy, even in serial production
- Faster production time compared to separate branch fittings and welding
What sizes and configurations can we produce?
Our pipe collaring machine covers the following range:
-
Main pipe diameter: Ø33.7–323.9 mm / 1”–12”
-
Formed branch diameter: Ø21.3–114.3 mm / ½”–4”
This size range covers most industrial, food & beverage, pharmaceutical, chemical, and mechanical engineering applications, from smaller DN50 branches up to larger DN200–80 configurations.
Where can it be applied?
-
Distribution of liquid and gas pipelines
-
Branches on pressure vessels
-
Heat exchangers and process pipework
-
Automotive and mechanical engineering solutions
Example from a recent project
We recently manufactured a DN200–80 stainless steel manifold, where a DN80 branch was formed directly from the main pipe.
By maintaining material continuity, the manifold achieved high pressure resistance and outstanding durability – completed in a single forming operation, without any weld seams.
