Metallic expansion joints are available from the Sudbury International inventory

Sudbury International carries various types of metal expansion joints.

Sudbury International Engineered Products Limited has been satisfying businesses with long-term, cost-efficient solutions for decades. Expansion joints – fabric, rubber, or dog-bone joints, particularly for ducting – take up a major portion of the supplier’s lineup. Sudbury International is a major source of metallic expansion joints, also known as compensators.

To help customers find the appropriate metallic expansion joints for their individual needs, Sudbury International relies on collective experience and expertise.

For thermal movement or vibration

Metallic expansion joints were invented in 1920 by Emil Witzenmann in Germany. They are compensating elements for thermal expansion and relative movement, each of which consists of at least one metal bellow, which is made with a multi-ply design, and of a connector at each end and some form of tie rods, as dictated by the application.

Pipelines, containers, and other types of machines frequently rely on the Sudbury International line of compensators. These joints are also useful in applications that involve thermal movement or vibration in several industries, like water treatment, energy, chemicals, pulp and paper, and oil and gas.

Suppliers and manufacturers typically classify metallic expansion joints according to their types of movement. The first category, axial compensators, consists of joints that absorb the thermal expansion of a straight-lined section between two fixed points. The distance between the points dictates the length of the pipeline that needs compensation and, as a result, the axial movement that the joint needs to achieve.

The second kind is angular expansion joints. At least two angular compensators are required for angular compensation of thermal expansion. Full compensation frequently needs three of them. These joints offer many combination options for two- or three-hinge systems.

The third option, known as lateral compensators, is associated with flow redirection by a right angle in single-plane or multi-plane piping systems. The standard practice is to install these expansion joints in existing 90-degree redirections in these piping systems. The movement of this compensator consists of the necessary lateral movement and a small axial movement from the joint.

For every situation, Sudbury International delivers the ideal solution.
