Design to avoid crevice corrosion PROCESS pipe work is extremely susceptible to crevice corrosion at pipe supports, resulting in replacement of entire sections – failures can potentially have catastrophic results. pipework where anti corrosion properties are paramount – eg in the field of offshore oil and gas exploration. Its design, based on the tried and tested Stauff Clamp according to DIN 3015, offers installation time reduction and long term cost savings due to extended service intervals. Stauff ACT Clamp (with highlighted rubber strips) The Stauff ACT Clamp is an innovatively designed solution for the installation of

Belt grinding machine Bossi Srl – Macchine Finitura Metalli, a leader in the manufacture of machines for metal surface finishing, has acquired an important order concerning the finishing of titanium bars for aeronautical use, up to a diameter of 430mm. The supply consists of a belt grinding machine, Mod HO/2UL Special, for reducing the surface roughness before ultrasonic non-destructive testing. For avoiding any contamination of the material, the machine works with pure water, and for this reason almost all of the grinding machine is made of stainless steel. The adjustment of the different diameters is automatically made by PLC, as well as the working pressure compensation. The machine is equipped with a special washing circuit for removing the abrasive slurries even inside the hoods containing the abrasive belts, an outlet drying system and centralised greasing equipment. The machine has been completely designed by means of a new generation 3D system with automatic processing of the bill of materials, printing of the detailed drawings regarding the parts to be manufactured and the assembly drawings. With this system it is possible to show the machine development to customers step-by-step, and

Throughout its development, Stauff ACT Clamps have been subject to stringent testing at the company’s in-house facilities in Werdohl, Germany. In order to ensure credibility of the product, the development process also involved independent testing. To achieve this, the services of Sheffield Hallam University, Centre for Corrosion Technology have been utilised. In a controlled laboratory environment, a salt spray test has been applied to various clamp configurations holding AISI 316 stainless steel tubing.
