ngular Expansion Joints Technical Data

Product catalog summary
Overview: The document provides comprehensive technical data on angular expansion joints, focusing on welded end bellows. It covers specifications for various types and sizes, detailing their nominal angular movement capacity, overall length, weight, outer diameter, bending spring rate, additional moment from rotation and pressure, and hinge friction per bar.
Specifications: Detailed specifications are provided for angular expansion joint types 7510, 7520, 7610, and 7620. Each type includes specific dimensions and performance characteristics such as nominal diameter (DN), pressure nominal (PN), and angular movement capacity (±α).
Temperature and Pressure Reduction Factors: The document outlines reduction factors for pressure (Kp) and movement capacity (KΔ) across various temperature ranges, from -10°C to 400°C. These factors are essential for assessing joint performance under different thermal conditions.
Order Information: The document specifies an order text format for each expansion joint type, including parameters like DN, PN, and angular movement capacity, ensuring accurate communication of product specifications during ordering.
Material and Design Considerations: Standard flange materials are suitable up to 300°C, with recommendations for special arrangements for higher temperatures during ordering, emphasizing the importance of material selection based on operating conditions.
Technical Notes: A deviation of ±30% in technical specifications is noted, with a reservation for potential technical changes, indicating that specifications may be updated or modified as necessary.
