Flexider Transfer Lines & Integrated Systems
Flexider USA can design and fabricate expansion joints that are shop-integrated into ducting and piping systems. This can eliminate dangerous, time-consuming, and costly field welds by allowing a section to be bolted or welded into the field at the engineered connection points instead of at the bellows. Mitered elbows, piping systems, round and rectangular ducting can all be fabricated and shipped to the site ready for installation.

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.

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 joint expansion 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 significant 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. For example, 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 of experience in the joint expansion industry. Metal expansion joints are all designed by Expansion Joint Manufacturers Association (EJMA) standards.
Firstly, Flexider Industrial has a clear and overriding objective: 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 crucial 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 catalyst or flue gas temperature may be as high as 1,400 °F, the inner 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 piping inside to reduce heat transfer to the expansion joint shell.
- Refractory Anchors: T304H stainless steel anchors 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 reduce 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 inner insulation.
- Internal Insulation: The internal insulation reduces the bellows operating temperature below the creep temperature and prevents catalysts from packing in the cavity between the inner 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 complete bore design that reduces the flue gas pressure drop flowing through the expansion joint. In addition, the inner 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 whole temperature of the media and the insulated bellows element using 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 may be 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 can absorb 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 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. However, if the inner ply develops a leak, the outer ply then keeps the tension. This alerts personnel to take precautions to repair or replace failing bellows as soon as possible.
Flexider Industrial Oversize Clamshell Bellows
If 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.
