Enhanced Corrosion Resistance of Stainless Steel Mounting Hardware

(Werdohl, March 2013)

Enhanced corrosion resistance of stainless steel mounting hardware for pipe and tube clamps

Press release on the occasion of Hanover trade fair

During the production and industrial processing of stainless steel, it is almost inevitable that both metallic and non-metallic particles contaminate the surface of the stainless steel and negatively influence its material properties. The composition of the self-healing oxide protective layer is often so impaired that corrosion may occur under particularly unfavourable ambient conditions such as the rigors of an offshore environment, causing permanent and irreversible damage to the components.

As a specialist in the field of pipe, tube and hose fastening, Stauff is again setting new standards at the Hanover Fair in April 2013: In order to meet growing customer needs for corrosion resistant parts, notably in the offshore and process industry sectors, the company has expanded its range of products to include selected stainless steel accessories for pipe and tube clamps according to DIN 3015. In addition hexagonal head bolts, cover and weld plates, hammerhead bolts and self-locking nuts are also available in this innovative stainless steel design that Stauff is offering under the material code W55.

These parts are available from stock in the standard and twin series according to DIN 3015 (parts 1 and 3) and facilitate easy and safe installation of clamps in DIN groups 1 to 3 for pipes and tubes with commonly used outer diameters between 6,4 mm and 25,4 mm.The components mentioned are manufactured from the materials 1.4401 and 1.4571, respectively. In contrast to regular stainless steel components, Stauff have developed methods to address the issue of contamination from metallic and non-metallic particles and practically excluded them during production, processing and handling. In order to avoid contamination of the components during transport, they are only distributed and delivered in complete packaging units of 25 pieces per bag. To also guarantee the optimum level of corrosion resistance after installation, the company additionally recommends that W55 parts are stored separately from carbon steel and any other metals, and that appropriate carbon free tools are used to assemble the clamps.

This makes the components a perfect complement to the ACT clamps recently launched by the company, which prevent crevice corrosion on pipelines in the offshore and process industry, thanks to their innovative design. Providing users with cost savings in medium and long term due to the extended maintenance and replacement periods the product offers.
