xial Expansion Joints Technical Data

Product catalog summary

Overview: The document provides comprehensive technical specifications for various axial expansion joints used in piping systems to manage thermal expansion and contraction. It categorizes joints by type, such as welded ends, flanges, inner sleeves, screwed ends, and Van-Stone ends, each with specific features like external shrouds and pre-stressing.

Types of Axial Expansion Joints:

Welded Ends: Designed for direct welding, available with or without external shrouds, suitable for diameters DN 200 to DN 1000.
Flanges: Facilitate easy installation and removal, with options for external shrouds, covering similar diameter ranges as welded ends.
Inner Sleeves: Provide additional protection, available with welded ends and flanges, can include external shrouds.
Screwed Ends: Made from materials like malleable cast iron, suitable for smaller diameters without pre-stressing.
Van-Stone Ends: Specialized for sound absorption, may include external tie rod restraints.

Technical Specifications:

Nominal Movement Capacity: Specifies axial and lateral movement capacities for each joint type.
Spring Rate: Indicates the force required to compress or extend the joint by a unit length.
Temperature Reduction Factors: Provides reduction factors for pressure and movement capacity across temperature ranges.

Data Tables: Extensive tables detail dimensions, weights, and performance characteristics, including overall length, outer diameter, and vibration characteristics.

Ordering Information: Includes order text formats specifying parameters like diameter (DN), pressure rating (PN), and movement capacities.
