Flexider USA Engineering and Fabrication of Metal Expansion Joints. Metal Expansion Joints are designed to absorb axially. As well as, lateral and angular motion in any combination as a result of thermal or mechanical movements. They are divided into different families. Each one is designed for its intended purpose and varying workload conditions: Axial Expansion Joints Lateral Expansion Joints Angular Expansion Joints Universal Expansion Joints Metal Expansion Joints can be provided with round or rectangular sections. Furthermore, are designed to meet the specific needs of the customer. Fabrication of Metal Expansion Joints. The Metal Bellows element is produced beginning with a thin sheet of steel that is precision rolled and welded into a tube that is then mechanically or hydraulically formed into convolutions in quantity and shape to meet the engineering requirements. Typically, flanges or weld bands are then added to the ends of the bellows element to aid in field installation due to the thinness of the material. Tie rods, hinges, covers, and liners can then be added to the assembly to accommodate the design specifications. Finite Element Analysis of Tie Rods Metal Expansion Joint Engineering. Flexider designs and engineers all Metal Expansion Joints to the current edition of the Standards of the Expansion Joint Manufacturer s Association. (EJMA) When required, expansion joints are also designed to ASME Section VIII Division 1, Appendix 26, B31.3 Appendix X, and ASME B31.1. Engineering design for all metal expansion joints starts at the inquiry stage and a Bellows Design Analysis (BDA) is prepared for each expansion joint required. Testing of Expansion Joint with Retaining Rings Design drawings for every order released for manufacturing is modeled entirely within SolidWorks to guarantee accurate fabrication details.

Flexider industrial was recently acquired. Please contact Dannenbaum LLC for more information or an RFQ. In this paragraph, I’m going to tell you about Flexider Industrial. Flexider Industrial is a worldwide supplier of expansion joints for Fluid Catalytic Cracking Unit (FCCU) applications. Also, these expansion joints must withstand some of the most challenging conditions of any industry. However, few expansion joint manufacturers have the resources to design and manufacture products to meet these demands. Moreover, Flexider Industrial has a long-established record of manufacturing dating back to its founding in Turin Italy in 1921. Flexider Industrial has since expanded to other countries including a major manufacturing facility located in Oak Ridge, Tennessee. Industrial Manufacturing Company International is the parent company of Flexider. IMCI companies produce a wide variety of products for industry. The Flexider Industrial group provides expansion joints and other related items to the aerospace, automotive, and industrial markets.
Design and Engineering
Firstly, Flexider Industrial specializes in the custom design and engineering of FCCU expansion joints. Moreover, these items require a high degree of technical expertise. Our employees have an average of over 20 years experience in the expansion joint industry. Metal expansion joints are all designed in accordance with Expansion Joint Manufacturers Association (EJMA) standards.
Firstly, Flexider Industrial has a clear and overriding objective that our customers should be satisfied with our products, services, prices, and employees. Thus commitment to our customers is further realized by maintaining a practical but comprehensive Quality Management System and implementing its continuous improvement.”
The FCC process is one of the most important conversion processes in a petroleum refinery. Furthermore, the process converts high molecular weight hydrocarbon fractions of petroleum crude to more valuable products such as gasoline and olefinic gases.
Flexider Cold Wall Expansion Joints
- Flexider Industrial Cold wall expansion joints utilize a high-density internal refractory lining to reduce the design temperature of the shell/piping below the temperature of the internal media. Although the temperature of the catalyst or flue gas may be as high as 1,400 °F, the internal refractory lining reduces the shell temperature below 650 °F. As a result, carbon steel is usually specified for the piping material of a cold wall expansion joint.
- Design Features of a Cold Wall Expansion Joint Flexider
- External Insulation: The external insulation elevates the bellows operating temperature above the internal dew point condensation temperature to minimize corrosion on the inner ply of the bellows.
- Refractory: High-density refractory insulates the inside of the piping to reduce heat transfer to the expansion joint shell.
- Refractory Anchors: T304H stainless steel anchors are used to anchor the high-density refractory lining to the carbon steel shell.
- Liner Gaps: Both the longitudinal and radial gaps at the open downstream end of the liner are sized for the design movements of the expansion joint. These gaps are minimized as much as possible to minimize the amount of catalyst that can enter the liner cavity.
- Liner Seal: The liner seal minimizes the amount of catalyst entering the cavity between the internal flow liner and the bellows. The liner seal also protects the structural integrity of the internal insulation.
- Internal Insulation: The internal insulation reduces the bellows operating temperature below the creep temperature and prevents catalyst from packing in the cavity between the internal flow liner and the bellows.
- Hex Mesh: The inside of the internal flow liner contains a hex mesh lining.
Flexider Industrial Hot Wall Expansion Joints
Hot wall expansion joints are commonly found in the flue gas piping throughout an FCC unit. Hot wall expansion joints on the inlet and outlet piping of an expander are unlined to eliminate loose pieces of the abrasion-resistant lining from traveling through the expander.
Flexider Industrial Design Features of a Hot Wall Expansion Joint
- The shear spool transfers the pressure thrust load and any external design loads. From the external hardware to the line pipe.
- The internal insulation reduces the bellows operating temperature below the creep temperature of the bellows material.
- The external insulation elevates the bellows operating temperature above the internal dew point condensation temperature to minimize corrosion on the inner ply of the bellows.
- The internal telescoping flow liners are a full bore design that reduces the pressure drop of the flue gas flowing through the expansion joint. The internal telescoping flow liners create a cavity for the internal insulation which is critical in reducing the bellows operating temperature.
- The smooth transition of the expanded line pipe minimizes the thermal stresses caused by the differential radial thermal growth. Between the line pipe operating at the full temperature of the media and the insulated bellows element operating at a reduced temperature.
- Pins welded to the outside of the shear spool slide thru corresponding holes in plates welded to the floating rings.
- Due to insulation installed between the line pipe and the inside of the floating ring. The floating ring operates at a much lower temperature than the line pipe. In many cases, the floating ring may be carbon steel even though the flue gas temperature maybe 1,450 deg. F.
The gimbal hardware allows the expansion joint to absorb angular movement in all planes.
The hinge hardware allows the expansion joint to absorb angular movement in one plane. Moreover, hardware is designed to restrain pressure thrust and other external loads.
Flexider Industrial Pantograph
Pantograph linkages equalize the axial movement each bellows of a universal assembly. The center gimbal ring allows the expansion joint to offset in the opposite plane to the pantograph without the linkage binding.
The expansion joint is capable of absorbing large lateral movements while the tie rods absorb the pressure thrust load.
Flexider Bellows Design
The expansion joint bellows reliability is critical for FCC units as they generally stay online for long periods of time between shutdowns. For this reason, bellows design incorporates a redundant pressure-retaining ply combined with leak detection hardware.
Flexider Two-Ply Testable Bellows
The inner ply retains the pressure under normal circumstances. If the inner ply develops a leak, the outer ply then retains the pressure. This alerts personnel to take precautions to repair or replace failing bellows as soon as possible.
Flexider Industrial Oversize Clamshell Bellows
In the event of a bellows leak through both bellows plies it may be possible to install oversize clamshell bellows over the existing bellows while the unit is online. The bellows have a weld end that allows attachment to existing endplates.
