STAUFF Single Weld Plate (Type SP – Twin Series)

Description

Specifications and Regulatory Compliance

The STAUFF Single Weld Plate (Type SP – Twin Series) is an essential fastening component for hydraulic systems. Designed and manufactured in strict compliance with DIN 3015, Part 3, this plate belongs to the STAUFF Twin Series. Its design is optimised to provide a robust and precise weld base, which is essential for the stable anchoring of pipe clamps in industrial installations.

Dimensional Classification

The component is classified as a Single Weld Plate, identified by the abbreviation “SP” in the manufacturer’s coding system. The range meets various dimensional requirements and is organised according to STAUFF Groups and the corresponding DIN Groups. Specifically, the available variants include Group 1D, corresponding to DIN 1, Group 2D, corresponding to DIN 2, Group 3D, corresponding to DIN 3, Group 4D, corresponding to DIN 4, and Group 5D, corresponding to DIN 5. Each group features precisely defined dimensions in terms of length (L), width (B), thickness (S), height (H) and diameter (D), designed to accommodate the respective clamp bodies with millimetric accuracy.

Construction Features and Materials

To suit different operating environments and strength requirements, the plate is available in four distinct material options, each identified by a specific ordering code:

• W2: Carbon steel with a phosphated surface finish (standard option).
• W3: Carbon steel with a zinc/nickel-plated surface finish.
• W4: V2A stainless steel, compliant with grades 1.4301 and 1.4305 (AISI 304/303).
• W5: V4A stainless steel, compliant with grades 1.4401 and 1.4571 (AISI 316/316 Ti).

As documented, alternative materials and surface finishes may also be available upon request.

Dimensional Variants and Threads

A critical element for assembly is the thread (G) integrated into the plate structure. The component offers two thread standards to ensure compatibility with international fastening systems:

1. ISO Metric Thread (Code M): Group 1D is provided with an M6 thread, while Groups 2D, 3D, 4D and 5D use an M8 thread as standard.
2. Unified Coarse Thread (Code U): The UNC alternative uses a 1/4-20 UNC thread for Group 1D and a 5/16-18 UNC thread for Groups 2D to 5D.

The ordering code system for the standard options follows a precise structure, with each segment uniquely identifying the plate type, size group, thread type and construction material, for example SP-1D-M-W2, ensuring the exact selection of the technical component required for the specific hydraulic application.
