The STAUFF Multiple Weld Plate (Type RAP – Twin Series) is an essential base component for the rigid and parallel fastening of pipes in hydraulic circuits. Manufactured in strict compliance with the dimensional and design specifications of DIN 3015, Part 3, this type of plate, defined as a Group Weld Plate, is specifically designed to accommodate a predefined number of five clamp bodies (Number of Clamps: 5). The use of the Twin Series ensures a high degree of stability for multiple linear installations in confined spaces.
The component is available for five different STAUFF Groups, identified by the designations 1D to 5D, corresponding to DIN Groups 1 to 5. The dimensions vary proportionally according to the selected group to accommodate different pipe diameters. For example, the total length (L1) ranges from 196 mm for the smallest Group 1D to 558 mm for the largest Group 5D. A critical parameter for correct installation is the pipe centre spacing (L2), which measures 40 mm for Group 1D, 58 mm for Group 2D, 72 mm for Group 3D, 90 mm for Group 4D and 112 mm for Group 5D. The plate thickness (S) remains constant at 5 mm for all RAP groups, ensuring uniform and robust welding to the supporting structure.
The STAUFF Multiple Weld Plate (Type RAP – Twin Series) features integrated threaded holes required for securing the upper part of the clamp. The manufacturer supplies all threaded parts with two different thread types. ISO metric threads (M) are available in size M6 for Group 1D and M8 for Groups 2D to 5D. Alternatively, Unified Coarse threads (UNC – U) are available in size 1/4-20 UNC for Group 1D and 5/16-18 UNC for the remaining larger groups.
To operate effectively in a wide range of application environments, STAUFF offers a complete selection of materials and surface finishes, identified by a specific code at the time of ordering. Standard options include:
Alternative materials and additional surface finishes are also available upon request.
The structured coding system for these hydraulic components follows a precise sequential logic, as illustrated by the code RAP-1D-40-5-M-W1. This indicates: the group plate type (RAP), the STAUFF Group (1D), the pipe centre spacing in mm (40), the number of clamps (5), the thread type (M) and, finally, the material code (W1).
