Fittings
Wilhelm Schulz GmbH is a leading German manufacturer of high-quality buttwelded fittings, serving global industries with precision-engineered solutions.
The Wilhelm Schulz Cold Forming Advantage
Our proprietary Wilhelm Schulz GmbH Cold Forming Technology offers a distinct edge over traditional hot forming methods, delivering superior performance, material integrity, and cost efficiency.
Optimized Base Material Selection
We use standard-sized pipes identical to those in your piping systems eliminating long lead times and minimum quantity requirements, especially for exotic alloys.
Superior Wall Thickness Distribution
As the market leader in this area, we ensure superior wall thickness distribution. Our cold forming process concentrates material exactly where it's needed, in the crotch area, resulting in thicker inner walls, reduced material usage, and lower overall costs. Stress is concentrated in the crotch area of fittings.
High Dimensional Accuracy
Precision tooling guarantees consistent geometry and tight tolerances across all fittings.
Damage-Free Forming
Even fittings with extreme diameter-to-wall thickness ratios are formed without mechanical damage, preserving structural integrity.
Gentle Material Handling
Minimal deformation (less than 10% axially, nearly 0% radially) ensures the material retains its original properties.
No Thermal Stress
Cold forming at room temperature avoids heat-induced defects. The grain structure remains intact, free from microcracks or structural loosening.
Technology by Wilhelm Schulz
All Wilhelm Schulz fittings with wall thicknesses up to 6 inches are cold formed and solution annealed, offering significant advantages for high-performance materials such as Duplex and Super Duplex.
These materials are highly sensitive to heat input, which can compromise corrosion resistance and mechanical stability. Our process ensures consistent quality that mirrors the raw material’s original properties without the risks associated with hot forming.
