Hinged metal bellows are specialized types of expansion joints designed to absorb angular movement in a single plane while controlling system stability through a hinged support arrangement. These bellows consist of a corrugated metal element (usually stainless steel or high-alloy steel) connected with a hinge mechanism at both ends. The hinge hardware restricts movement to a specific direction, allowing the bellows to rotate only in one plane while preventing axial extension or lateral deflection. The main purpose of hinged metal bellows is to accommodate angular rotation between connected piping sections, commonly where piping layouts experience directional changes or where controlled movement is required. They are commonly used in: Power generation plants Oil and gas pipelines Refineries and petrochemical industries Steam and high-temperature ducting systems Industrial process piping Key features: Absorbs angular movement in one plane only Strong mechanical stability due to hinge support Prevents unwanted axial and lateral movement Reduces stress on piping systems Suitable for high-pressure and high-temperature applications Overall, hinged metal bellows provide a controlled and reliable solution for managing angular movement in piping systems, especially in applications where directional movement must be restricted and precisely guided for safety and efficiency.

We are offering Double Hinged Expansion Bellow to our client. Specification:Material: Stainless SteelConnection: FlangeBellow Sizes: 50NB - 6000NBBrand: Athulya

Sizes 80mm -3 meter N.B. (Larger sizes can be supplied) Pressure Ranges up to 40 kg/cm2 Generally installed in multiples of two or three, these joints are designed for angular movements in one plane only. A hinged mechanism contains the pressure loads and ties back to an integral flange or box restrained lug. Limit stops control the degree of angular movement . These units can be fitted with either pipe ends or flanges, can be supplied with two hinged system also.

Hinged Bellows, either Axial or Universal type, are designed to absorb angular rotation in one plane only by the use of a pair of pins through hinge plates attached to the expansion bellows. Hinged Expansion Bellows should be used in sets of 2 or 3 to function properly. Hinged Bellows are normally prevented by their design from deflecting axially, either in extension or compression. The hinge mechanism is usually designed to accept full pressure thrust and also shear loads such as from the weight of the adjacent piping, can be accepted by these type of expansion joints thereby doing away with provision of additional supports and anchors. Hinged Bellows also have added benefits of positive control over the movements, eliminates pressure thrust forces, transmits external loads, prevents torsion on bellows and are the most efficient in absorbing of thermal deflections.

These are basically two single hinged bellows combined into one unit with a common tie bar joining the two extremities. Therefore any expansion of the centre pipe within the limits of the bar will simply compress the bellows and will not exert any movements on the adjoining pipe works

Sizes 80 mm -3 metre N.B. (larger sizes can be supplied) Pressure Ranges up to 40kg/cm2 Two hinged joints are joined together by a centre tube, allowing large lateral movements at high pressure and can be fitted with pipe ends or flanges. Limit stops control the degree of movement.

Hinged Expansion Joints have a single bellows and have their length restrained by the addition of hinge mechanism which is strong enough to accept the pressure generated thrust but will allow angular movement in a single plane. Slotted Hinge Expansion Joints are a variant of the above "Hinged" type, in that while providing for angular movements, some axial movement can be accepted because the hinge pin passes through slots in the hinge plates. When the axial movements is occurring the expansion joint is incapable of accepting the pressure thrust. The hinge structure can be designed to accept the full pressure thrust when the pin is at the limit of its travel within the slot

Hinged Expansion Joints are used to absorb angular movement when it occurs in only one plane. They are also called as Angular Expansion Joints or Hinged Bellows. The construction of the hinged bellows consists of two hinges connected by a common hinge pin. These hinges are designed to absorb the full pressure thrust of the expansion joint. In addition they can be designed to support the dead weight of the piping and equipment, wind loads and similar external loads.

These expansion joints contain hinges which cause the unit to bend in a single plane. Normally these un its are prevented by their design from deflecting axially, either in extension or compression. Their hinge mechanisms are usually designed to accept the full pressure thrust. Also, because of the hinge mechanism's design, shear loads, such as from the weight of adjacent piping, can be accepted by this expansion joint, relieving the piping designer of having to provide additional supports and anchors required by the Single type. Some hinge types can be provided with hinge pin holes which are slotted to permit limited axial travel. These "slotted hinge" types will not resist pressure thrust forces, and anchoring must be provided.

We are one of the renowned companies of Hinge and Gimbal Bellows. These are made as per industry standards and norms Features: Impeccable finishRust resistantCost effectiveDurable natureEasy to use Design: Hinge and gimbal Types of motion: Used for Angular Motion.Used in various combination of 2 or 3 joints to absorb axial lateral and Angular movementsaxial only.

A hinged Expansion joint is an assembly designed to absorb angular rotation in the plane perpendicular to the hinge pins. The hardware consists of two hinged plates 180 apart and joined to the end connection. The hinged hardware is designed to absorb the pressure thrust of the Expansion joint assembly. Features: Angular motion in all planes Eliminates pressure thrust forces Prevents torsion on bellows Most efficient in absorbing thermal deflections
