Easyflex Rubber expansion joints, also known as rubber bellows, are key players in a variety of applications, offering a crucial solution for managing movement, vibration, and misalignment in pipelines and ducting systems. Easyflex rubber expansion joints are designed to absorb movement in piping and ducting systems. They are the dynamic components that flex, stretch, and compress to compensate for the forces generated by thermal expansion, pressure fluctuations, and mechanical vibrations. These joints are made from high-quality rubber compounds, making them resilient, cost-effective, and highly versatile.

Easyflex Universal Metal Expansion Joints are constructed with two metal expansion bellows of an equal length separated by a center pipe. This expansion joint design will accept large amounts of lateral offset in multiple planes. The amount of deflection is based on the amount of angulation each bellows can take and the length of the center spool. Tie rods are required where it is necessary to absorb full pressure thrust and other externally applied loads. Easyflex Universal Expansion Joints are normally designed to absorb any combination of axial and lateral movement and angular rotation in multi-plane piping arrangements. They are extremely well suited to the absorption of large amounts of lateral displacement. The magnitude of the lateral displacement can be varied considerably because any increase in the length of the center pipe spool produces a corresponding increase in allowable lateral deflection. In installations involving large amounts of thermal change, where there is a change in elevation of the piping or where offsets exist, it is frequently possible to install Universal bellows expansion joints in the offset or drop leg, which will absorb considerably more movement laterally than can be absorbed in compression by standard units.

The Tied Type Easyflex Universal Expansion Joints are usually constructed with either two sets of short tie rods, one set over each bellows, or with overall tie rods. A unit with the two sets of short rods is designed primarily to limit movement and stabilize the connecting pipe section. A unit with overall tie rods is designed to absorb full pressure thrust, to stabilize the connecting pipe section, and to absorb all external loads which are present, such as wind loads and weight of center pipe nipple where unit is exceptionally long.

Easyflex Concentric and Eccentric Reducers and Reducing Expansion Joints are designed to allows simple connection of different sized pipes. Reducing Expansion Joints also provide all the benefits of a standard Easyflex Expansion Joint. Reducers can be used as pipe reducers or increasers, expansion joints, flexible connectors, and vibration eliminators.

Easyflex Reducers were designed to replace metal reducers in the pipeline. Standard reducers have a smooth-walled reduction from flange to flange. Reducing Expansion Joints are available in single, double, and triple arches, in either open or filled models. The multiple arches are used in applications where expansion or contraction will occur. The advantage of an all-rubber reducer over a metal reducer is the flexibility and durability of the elastomer. Filled reducers are usually used on slurry and abrasive applications to prevent the collection of material, which can settle in the arches. Easyflex Reducers eliminate noise and isolate vibration in the pipeline, reduce stress, eliminate electrolysis, and protect against start-up surges. Concentric reducers save installation space and reduce costs.

Easyflex manufactures concentric reducers to meet your exact piping needs. The flanges are designed to meet your required specifications. Easyflex Reducers are available in a variety of elastomers to satisfy the chemical compatibility and temperature of the process fluid. Piping systems must be anchored when using concentric reducers. Standard control rods cannot be used to prevent over extension or elongation.

Expansion bellows can be designed with reinforcing or equalizing rings which are located around the outside of the convolutions, preventing bellows being forced out from high pressure. The principal purpose of these devices is to reinforce the bellows under internal high pressure, so that bellows does not squirm and equalize movement among all the convolutions. The disadvantage of these bellows is the increased stiffness and limited movement of the bellows.

The main mission of the Easyflex reinforced metal expansion joint for high pressure (High Pressure Metal Expansion Joint) is to absorb axial expansion movements both thermal and mechanical origin under high pressure conditions. The High-Pressure Metal Expansion Joint is composed of a single bellow of several waves in the form of “U”. These waves are made by one or more metal sheets longitudinally welded and shaped hydraulically or mechanically. Because of its configuration, the designer must bear in mind that this type of metal expansion joint transmit pressure stresses to the fixed points and guides of the piping system.

Easyflex filled arch expansion joints can accommodate media that might clog or degrade an open arch. These expansion joints can also be manufactured in reducing styles–both concentric and eccentric. Also, to accommodate greater pipe movements and to reduce spring rates, multiple arch styles can be built. Two or three arch expansion joints are common. Easyflex filled arch expansion joints are designed to be used with retaining rings, and control units when required.

Easyflex Rubber expansion joints offer several key advantages

• High performing expansion joints to minimize accumulation
• Inside of arch is filled with rubber
• Filled arch decreases joint flexibility by 50%

Easyflex Tied Pump Connectors are designed to compensate for multi-plane axial, lateral and angular movement in non-torsional applications. They are intended for use in both suction and pressure lines to absorb mechanical vibrations caused by pumps, compressors and other pipeline equipment. Easyflex Tied Pump Connectors aid in compensating for minor piping misalignment and helping to minimize the stress on your system. Heavy-duty restraining rods and spacers assure protection against bellows distortion in the event anchors are not properly secured and absorb mechanical vibration without hampering axial, lateral or angular movement of the pump connector.

Unlike rubber and elastomeric connectors, Easyflex Tied Pump Connectors are not subject to premature deterioration resulting from elevated temperature conditions or UV exposure. Thus, they offer a longer cycle life in a wide variety of temperature applications ranging from sub-zero to super-heated steam. In the latter case, it may be necessary to include the optional internal liner to prevent excessive flow velocity from damaging the assembly.

Custom-built assemblies are available to meet conditions beyond these specifications. Lengths other than standard are available upon request.
