Bellows Systems single-ply bellows elements provide superior fatigue life and movement capability compared to flexible hose (flex-hose) connectors. Single-ply metal bellows used in Bellows Systems standard Expansion Joints are made in all possible lengths and pipe sizes from 0.875" in diameter and up.
For that purpose, it's recommended to have the thickness of bellow limited up to 3 mm (0.1181 in). 3. Parametric evaluation of Unreinforced bellows based on variation in Number of plies(n): Expansion bellows are fabricated from single or multiple sheets of metal to get desired thickness of bellow.
Multi-ply bellows provide excellent flexibility and fatigue life compared to single-ply bellows. They also offer significant pressure containment capacity and are commonly used in applications where vibration may be present. Due to the higher number of tubes/plies used in multi-ply bellows, they are much more flexible than single-ply.
U.S Bellows, Inc. manufactured 10″ single tied titanium expansion joints to be utilized in a chemical plant in Kingsport, Tennessee. These single expansion joints are bellows elements with end connections that allow movement in any direction or plane. However, the piping must also be guided in the same direction of the movement.
How to Specify a Single Expansion Joint Special Note: If a non-standard flange rating is required or a non-standard weld end thickness is required or if the fittings are nonstandard materials, those preferences must be stated along with the part number. Step 1 Nominal Pipe Size Expansion joints are specified with part numbers starting with the nominal pipe size.

The single sphere rubber expansion joint is also known as a flexible joint or rubber bellow. It is manufactured as one moulded spherical piece, hence the same single sphere. The FSF spec is the Australian spec of rubber expansion joint, nationally recognised as being a decently sized sphere, not being too wide, and not being too narrow.
This pipe expansion joint is simply a bellows element with end connections. Regardless of accessories, such as liners and covers, it will deflect in any dire...
The theoretical design cycle life of this bellows is 27,566, far more than a single-ply bellows. The differences in the design cycle life and spring rates of the two example bellows above can help decide which bellows to purchase. However there are several factors that go into a bellows design, design cycle life and spring rates are just two of ...
Single Tied Expansion Joint . Single tied expansion joints consist of a single bellow with tie rods. The main advantage of having a single tied expansion joint is to overcome the reaction forces and spring rates, as these loads will be compensated within the bellow and therefore will not transfer to the pipe line.
Single Expansion Joints – Metal. Senior Flexonics is recognized as a leader in the metal expansion joint industry. Our leadership has been earned through consistent application of solid engineering principles, stringent quality standards and product innovation to produce safe and relaible metal expansion joints and flex connectors for HVAC piping and ducting applications.
Bellows are a flexible piping element. The corrugation of the Metallic Expansion Joint is designed to be flexible in order to absorb pipe expansion and contraction due to changes in temperature. The number of corrugation of bellows is decided according to the displacement amount and the expansionary and contracting force that the bellows have to absorb.

Single circular metal bellows, or 1 or more convolutions. Typical dimensions of ½" ANSI NPS to 240" ID. Overall length may vary, typically within the range of 6" to 30". Bellows may include reinforcement or controlling members; Convolutions may be U shaped or toroidal; Additional accessories may be incorporated such as load bearing
Maximum axial extension movement is 50% of tabulated axial value. To obtain greater movements or cycle life refer to step 5 How to Specify a Single Expansion Joint or contact the factory. Catalog pressure ratings are based upon a maximum bellows temperature of 800°F. Actual operating temperature should always be specified.
Two independent metal bellows elements fitted with pipe liners and a single external shell. This style of joint is most suitable for applications involving movements in long piping runs with large amounts of thermal expansion. Also recommended where maximum system safety is an issue, and protection of the bellows element is essential.
Single Expansion Joint Assemblies are the simplest type of expansion joint consisting of a single bellows element welded to end fittings, either flange or pipe ends. 2. Universal Expansion Joint Assemblies consist of two bellows connected by a center spool piece with flange or pipe ends.
A single expansion joint was custom designed for a gas turbine system in Mexico. The bellows, flanges, and limit rods are all fabricated from 316 L stainless steel. The bellows are 42″ diameter and the overall length is 16″. The expansion joints were designed for 140°F at 1 psig with 2″ of axial lateral movement.
The single pipe expansion joint is simply a bellows element with end connections. Regardless of accessories, it will deflect in any direction or plane that the bellows will. It requires that the piping be controlled as to the direction of the movements required of the unit.
Aflex Single Expansion Bellows allow for axial, lateral and angular deflection as well as combined movements. As SEB are unrestrained, the internal pressure from the bellows is transmitted onto the pipeline as pressure thrust (see pressure thrust page and calculator). To prevent buckling of the pipe or other damage to the system, this pressure thrust must be considered and properly restrained.
Exhaust Gas Expansion Joints can be manufactured incorporating one more bellow in the design for cases that the load exceeds the capacity of a single bellow. They can be fitted with a wide range of flanges, standard or custom made, with the option of being fixed or floating. Design: Double Multiply Bellow. Accessories: Liner, Tie Rods.
Single Expansion Joints come equipped with bellow elements and end connections like pipe ends, flanges, weld necks and other optional features such as collars, liners, and covers.The bellows will deflect in any direction or any plane depend on the pipe movement. It is a cost effectiv e design option but requires that the piping be controlled to the direction of the movements of the bellows …
