Your partner for stainless steel tube systems

Dockweiler AG is an innovative company with a long tradition of expertise. Established in 1955 in Hamburg, the company started out as a hardware business. Later, the focus was shifted to seamless tubes for standard applications. Today, Dockweiler specializes in high purity stainless steel tube systems for use in high-tech industries such as semiconductors, pharmaceuticals, biotechnology, and photovoltaics.

We offer the extra advantage of special, tried-and-tested productions methods. Whether our customers require orbital welding, surface optimization, or cleanroom production, we know what we‘re talking about and what we’re doing. Dockweiler offers specific surfaces for safe equipment: bright finish, pickled, anodically cleaned, or electropolished. With decades of expertise and experience in surface optimization and finishing, we can give our customers the very best advice on how to implement the requirements of their specific application – up to a Ra of 0.13 µm!

In addition to selling and producing standard components, Dockweiler has built up a state-of-the-art facility for special production requirements, including class 4 and 6 cleanroom for welding, assembling, and packing high purity assemblies for transporting UHP gases.
