Double Hinged Metal Expansion Joints

Q: What are the primary advantages of using Double Hinged Expansion Joints?

Double Hinged Expansion Joints are specifically engineered to manage both lateral and angular movements in a single plane. This design helps in minimizing stress on piping systems by accommodating thermal expansion and contraction, thus enhancing the overall durability and reliability of the piping system. They are also equipped with a double articulated system that effectively contains pressure thrust, making them ideal for high-pressure applications.

Q: How do Double Hinged Expansion Joints differ from other types of expansion joints?

Unlike other expansion joints, Double Hinged Expansion Joints are composed of two bellows connected by a linking pipe, which allows them to absorb movements in a more controlled manner. This is particularly beneficial in scenarios where space limitations prevent the use of larger, more complex expansion joint systems. Additionally, they provide a unique combination of flexibility and rigidity, which is essential for maintaining system integrity under varying operational conditions.

Q: In what applications are Double Hinged Expansion Joints most commonly used?

These joints are widely utilized in industries such as chemical processing, oil and gas, and power generation. They are particularly effective in systems that require frequent directional changes in piping or where there are substantial temperature fluctuations. For specific configurations, consider our Double Hinged Metal Expansion Joints - flanged or Double Hinged Metal Expansion Joints - welding ends.

Double Hinged Expansion Joints

Double Hinged Expansion Joints are designed to absorb lateral and angular movements in only one plane.

This special type of expansion joint is made up of two bellows joined together by a linking pipe and fitted with welding ends or flanges plus a double articulated system. The hinge mechanisms are designed to contain pressure thrust.

Double Hinged Expansion Joints can absorb Lateral and Angular movement in one plane. The double hinged expansion joint contains pressure thrust forces with no main anchors required and minimum guiding required

Double Hinged Metal Expansion Joints - flanged

Double Hinged Expansion joints are mounted to limit the expansion joint to absorb angular and lateral movements in only one plane in the hinged metal expansion joints. Due to the hinges the expansion joint is not able to absorb axial movement. The hinge is likewise designed to protect the bellow from torsion. These movement limiters reduce the loads from the pressure thrust force and the temperature of the pipeline. The pressure thrust force from the media is in this way abso..

Double Hinged Metal Expansion Joints - welding ends

The double hinged expansion joints are made of one double bellow element fitted with welding ends plus a system of articulated supports which allow for angular movement in one plane only. The hinge mechanism is designed to accept full pressure thrust. These units do not allow axial movement however, some types of hinge systems can be provided with holes for the hinge pin that are slotted to allow limited axial displacement. These “slotted hinge” types can not resist the press..
