Our Special pipes

Does your project require special additional processing? Our high quality pipe is also the base product for manufacturing high-quality special pipes and components ready for installation. Our combination of modern production technology, craft skills and years of experience allows us to produce for you special pipes with particular:

Surfaces

Depending on the material and the industrial application, BUTTING satisfies a range of requirements for inner and outer surfaces and the weld seam area. We therefore offer you both chemical surface treatments and a variety of mechanical ones.

Chemical pickling after production is standard at BUTTING. This guarantees pipes and components with optimum corrosion resistance.

You can also specify different surface types:

The choice of raw material depends on the specified nature of the surfaces
Rolling operations / flattening
Individual requirements for roughness
Grinding the inner and outer surfaces
Blasting the inner and outer surfaces
Deliberate roughening of the surfaces through Raumatic surface finishing

Form and position tolerances

Our stainless steel pipes and components are produced according to national and international standards, e.g. DIN, ISO or ASTM.

Beyond this, we implement any other requirements the customer may have with regard to special tolerances of the inside and outside diameter and the wall thickness. This is why numerous pharmaceutical companies have been relying on BUTTING pipes with very tight tolerances of the outside diameter for years.

We also produce stainless steel pipes for piggable plants, diaphragm pipes or valve housings, where the inside diameter is of the essence. Also in this sector we are your quality supplier. Our Quality Assurance system is part of each process, thus ensuring compliance with all individual requirements, e.g. squareness of the pipe ends - an important prerequisite for subsequent orbital welding.

Geometries

We have been producing corrosion resistant pipes in special geometries for many years, either as series production from coil or from plates for special components. Owing to the many production processes we have, a nearly unlimited range of different forms is possible:

Triangular pipes
Square pipes
Hexagonal pipes
Oval pipes
Elliptical pipes
Half shells

Renowned manufacturers of pumps, companies in process technology and research institutions rely on BUTTING's expertise. This is why we have supplied the Research Centre CERN in Geneva with special copper-clad oval pipes and half shells for the largest particle accelerator.

Our high-quality special pipes are in use all over the world, for example as piggable pipes, food industry pipes or pharmaceutical industry pipes
