Round steel U-bolts of the RBD series as per DIN 3570 (form A) from Stauff are designed for surface or hanging installation of pipelines with outer diameters and nominal widths of more than 500mm. They are usually made of zinc plated steel or stainless steel and are popular with tube installers, who greatly appreciate the space-saving design and easily implemented installation principle in addition to their wide range and quick availability.
The round steel U-bolts which were made using the company's innovative ACT concept. In this case, ACT (Anti-Corrosion Technology) refers to a two-piece insert made of flame-retardant plastic material, which is placed between the U-bolt – designed in compliance with DIN requirements – and the pipe. The integrated elastomer strips – two in each half – clamp the line without allowing the component to have contact with metal, and therefore effectively prevent the formation of corrosion. This design also avoids the accumulation of seawater and other corrosive media in the gap between the insert and the pipeline.
In case that the round steel U-bolts are manufactured from stainless steel, the solution meets all market requirements as (for example) defined in the Norwegian Offshore Standard Norsok Z-010 (Revision 3) from October 2000 (Section 7.3: Tubing installation).
