STAUFF Extended Weld Plate for Single Clamps (Type SPAL-DUEB – Heavy Series)
Designed for demanding hydraulic applications in accordance with DIN 3015 Part 2, the STAUFF Extended Weld Plate for Single Clamps (Type SPAL-DUEB – Heavy Series) ensures robust and durable fastening. It supports metric and UNC threads and is available in carbon steel and stainless steel (V2A/V4A). Ideal for the secure installation of high-pressure pipework in the most demanding industrial environments. The available product codes (with the corresponding M/U thread and W1-W5 material variants) are: SPAL-DUEB-3S, SPAL-DUEB-4S, SPAL-DUEB-5S, SPAL-DUEB-6S, SPAL-DUEB-7S, SPAL-DUEB-8S, SPAL-DUEB-9S, SPAL-DUEB-10S, SPAL-DUEB-11S, SPAL-DUEB-12S.
STAUFF Extended Weld Plate for Single Clamps (Type SPAL-DUEB – Heavy Series)
The STAUFF Extended Weld Plate for Single Clamps (Type SPAL-DUEB – Heavy Series) is an excellent solution for fastening pipework in high-pressure hydraulic systems. Specifically designed to support Heavy Series single clamps, this plate provides a solid and durable anchoring base, essential for preventing vibration, wear and structural failure in industrial systems. Compliance with DIN 3015 (Part 2) confirms its suitability for the most demanding applications.
The Extended Weld Plate design of the SPAL-DUEB variant is engineered to provide a larger welding surface, optimally distributing mechanical and thermal stresses. This configuration significantly improves the stability of the installed single clamp, especially in the presence of dynamic loads or pressure fluctuations typical of complex hydraulic circuits. The threaded components are manufactured with high dimensional precision to ensure perfect engagement with the fastening bolts.
To meet different environmental and operating requirements, the plate is available in a wide range of materials and finishes, identified by specific codes:
Installation flexibility is ensured by the availability of two thread types:
The plates cover STAUFF Groups 3S to 12S (corresponding to DIN Groups 1 to 10), allowing support for pipework of various diameters. The physical dimensions vary proportionally according to the group, with lengths starting from 113 mm for Group 3S and reaching 750 mm for Group 12S, ensuring perfect scalability for every type of hydraulic project.
