Universal Tied Expansion Joint
DN600
The Universal Tied Expansion Joint is a metal expansion joint consisting of two bellows connected by a central spool pipe, with tie rods designed to restrain pressure thrust. It primarily absorbs multi-plane lateral movements, and can also accommodate axial or angular deflection depending on tie rod configuration. Available in a wide range of pressures, temperatures, diameters, and materials, it is widely used in oil & gas, chemical, and power generation industries for complex piping systems where space for heavy anchors is limited. Its key advantages include thrust restraint, stress reduction on equipment, and compliance with EJMA standards.

**Product Overview**
The Universal Tied Expansion Joint is a high-performance metal expansion joint engineered to absorb lateral movements in all planes while effectively restraining pressure thrust. This model consists of two bellows elements joined by a central spool pipe, complemented by a robust tie rod system designed to withstand the thrust generated by internal pressure.
**Key Features & Capabilities**
This expansion joint is primarily designed to absorb multi-plane lateral movements. Depending on the design and positioning of the tie rods, it can also accommodate certain axial and angular movements. Unlike unrestrained types, the tie rod system effectively restrains pressure thrust, thereby protecting connected equipment and piping supports from excessive loads. With two tie rods positioned at 180 degrees, the joint allows both angular and lateral deflection. With three or more tie rods installed, it accommodates lateral deflection only. Furthermore, the lateral deflection capacity can be modified by altering the length of the central spool pipe, offering excellent flexibility to meet specific system requirements.
**Technical Specifications**
The Universal Tied Expansion Joint is available with a design pressure ranging from 0.5 barg up to 40 barg, and a diameter range from DN25 to DN5500, with custom sizes available upon request. The design temperature ranges from -20°C up to 800°C, depending on the materials selected. Bellows can be manufactured from a variety of materials including Stainless Steel 321, 309S, and 316L. End connections are offered as fixed flanges, floating flanges, or welding ends per project requirements. Optional accessories include internal or external liners (sleeves) and leak detection systems for enhanced safety and performance monitoring.
**Typical Applications**
The Universal Tied Expansion Joint is widely used in complex piping systems across industries such as oil and gas, chemical processing, petrochemical, and power generation. It is particularly suitable for Z-shaped pipe configurations requiring absorption of lateral movements in tight spaces, as well as high-temperature and high-pressure systems such as cracked gas lines where pressure thrust must be carefully managed. It is also an ideal choice for piping networks with limited space for heavy anchoring systems, as the tie rods effectively reduce thrust loads on fixed points.
**Advantages**
This product provides superior flexibility in managing multi-directional movements and effectively reduces stress on system anchors and equipment nozzles by restraining pressure thrust. It is available in a wide range of materials and sizes to suit corrosive, high-temperature, or cryogenic environments, and its reliable performance is backed by industry standards including EJMA (Expansion Joint Manufacturers Association) as well as rigorous quality control procedures.
