STAUFF Metal Clamps DIN 1593 – Heavy-Duty 2-Bolt Saddle

Description

Operating Principle and Applications

The STAUFF Metal Clamps DIN 1593 – Heavy-Duty 2-Bolt Saddle are components specifically engineered for the direct and secure installation of pipes, conduits, poles and other cylindrical components. The fastening system is carefully designed to provide a permanent and robust anchoring solution directly to the substrate. This highly versatile construction allows technicians to install the clamps on floors, walls or ceilings, adapting perfectly to the structural and spatial requirements of the hydraulic system layout in which they are integrated.

Design and Construction Features

The mechanical configuration of these metal clamps is based on a robust heavy-duty saddle design, technically known as a “Heavy Saddle”, featuring carefully optimised “Tension Clearance” in full compliance with DIN 1593 specifications. Structural fastening of the assembly is achieved through a proven “Two-Bolt Design”. This technical architecture is designed to ensure uniform and balanced load distribution, providing stable retention of the cylindrical component while effectively counteracting system stresses. Reference dimensional parameters, such as the overall assembly length (L1), centre distance between the anchoring holes (L2), overall height (H) and material thickness (S), vary proportionally according to the selected size group, providing highly precise and effective configurations for each specific outside diameter.

Dimensional Range and STAUFF Groups

STAUFF Metal Clamps DIN 1593 – Heavy-Duty 2-Bolt Saddle cover a broad and comprehensive range of outside diameters, from a minimum of 5.5 mm up to a maximum of 115 mm (corresponding to a range from 0.22 to 4.53 inches). These fastening clamps are technically classified into standardised STAUFF Groups, which define the correct dimensional tolerances for fitting:

• Group 7: designed for outside diameters from 5.5 to 7 mm
• Group 9: designed for outside diameters from 7 to 9 mm
• Group 13: designed for outside diameters from 9.5 to 13 mm
• Group 15.5: designed for outside diameters from 13 to 15.5 mm
• Group 19: designed for outside diameters from 15.5 to 19 mm
• Group 23: designed for outside diameters from 20 to 23 mm
• Group 26: designed for outside diameters from 23 to 26 mm
• Group 28.5: designed for outside diameters from 26 to 28.5 mm
• Group 31: designed for outside diameters from 28.5 to 31 mm
• Group 36: designed for outside diameters from 33 to 36 mm
• Group 39: designed for outside diameters from 36 to 39 mm
• Group 43: designed for outside diameters from 39 to 43 mm
• Group 46: designed for outside diameters from 43 to 46 mm
• Group 49: designed for outside diameters from 46 to 49 mm
• Group 58: designed for outside diameters from 53 to 58 mm
• Group 61: designed for outside diameters from 58 to 61 mm
• Group 71: designed for outside diameters from 67 to 71 mm
• Group 77: designed for outside diameters from 73 to 77 mm
• Group 81: designed for outside diameters from 77 to 81 mm
• Group 91: designed for outside diameters from 88 to 91 mm
• Group 103: designed for outside diameters from 99 to 103 mm
• Group 109: designed for outside diameters from 105 to 109 mm
• Group 115: designed for outside diameters from 110 to 115 mm

Materials, Surface Finishes and Order Codes

To precisely meet the wide range of environmental and operating requirements typical of industrial and hydraulic applications, these fastening clamps are manufactured in three specific material variants, clearly identified by unique codes for correct ordering. Material code W1 identifies the standard version made from uncoated carbon steel. Code W66 refers to the more highly protected version, manufactured from zinc-plated, thick-film passivated carbon steel for increased resistance to oxidising agents. Finally, for the most severe and demanding operating environments, code W5 identifies the complete structure manufactured from high-quality V4A stainless steel grades 1.4401 and 1.4571 (technically corresponding to the international AISI 316 / 316 Ti classification). The nominal order code structure is formed by combining the prefix of the reference standard, the STAUFF Group number and the unique material code, as shown in the format DIN1593-7-W66. Alternative materials and additional surface finishes are also available from the manufacturer upon specific request for non-standard applications.
