What is the need for bellows expansion joint in the piping system in India ?

What is the need for bellows expansion joint in the piping system?

An expansion joint pipe is a flexible component that is inserted into the pipelines to safely absorb the dimensional changes of steel piping systems and ducts.

What is Expansion Joint?

• Other terms used for expansion joints as expansion bellows, flexible joints, and compensator.

• An Expansion Joint is compressed by one or more metal bellows (stainless steel) or from material like rubber or fabric

• Metal bellows are suitable in all high temperatures; metal bellows have high strength properties and are resistant to corrosion

• The Metal bellows are implemented in such a way to absorb one of these movements or to absorb more of the movement in the combination

• The use of Expansion Joints will always prove to be the simplest and most effective method of compensating for thermal expansion and contraction.

What is the need for an expansion joint in the piping system?

• Expansion Joints bellows are used to absorb vibration and shock in the piping system.

• This also has the advantage of reducing the noise and compensating caused by misalignment.

What is a pipe expansion joint? why do we need it?

• Piping Expansion Joints or Expansion bellows are highly engineered mechanical devices containing one or more metal /rubber bellows.

• Expansion Joints are used to absorb the dimensional changes caused by the thermal expansion or contraction of pipeline ducts, vessels while containing the system pressure

• Expansion Joints are successfully used in the refiner’s .chemical and petrochemical plants, nuclear power plant, automotive and aerospace heating and cooling system.

Why Install pipe Expansion Joint

• To absorb the movement of thermal expansion as well compression

• To relieve the system stress and strain

• To reduce the noise and vibration

• To compensate for misalignment

What are the components of expansion joints?

Bellows

Tie rods

Flanges

Shipping bar

Protective cover and internal liners

What are bellows?

Bellows are part of the expansion piping joints.

There are two types

• Formed Bellows

• Fabricated Bellows

1. Formed Bellows

• Formed from the thin-walled tube

• Single & multiply

2. Fabricated Bellows

Use heavier gauge material than formed bellows
Fabricated bellows can withstand higher amount of pressure

Our Products Axial Expansion Joint Axial Expansion Joints are the simplest type of expansion joints using a single bellows unit. The thermal expansion of a straight pipe line section between two fix points can be absorbed by axial expansion joints with a relatively compact build-in length. Lateral Expansion Joint The Lateral Expansion Joints ...

What are metallic bellows and types of Bellows?

What are metallic bellows? The main element of the expansion joint, which consists of one or more convolutions, is called bellows . The performance of the bellow depends upon the geometric bellows. Hence the type of raw material and its properties, its geometric features, other influencing designing factors, construction or manufacturing method, and performance testing bellows are necessary to study. What are the types of bellows? Formed Bellows These types of Expansion Joint used in the low-pressure system they are cost-effective and can be a substitute to the system Fabricated Bellows Formed from a thin wall tube, formed bellows contains only longitudinal welds, and exhibits significant flexibility Formed Bellows shapes are made from single or multiply plies of suitable material (usually stainless steel) ranging in thickness from .004" to .125" and greater, and in diameter of 3/4 to over 12 ft

Externally Pressurized Expansion Joint | Flexpert Bellows

Externally Pressurized Expansion Joint Externally Pressurized Expansion Joint is the perfect solution when the expansion joint must absorb large axial movement under High Pressure. Externally Pressurized Expansion Joints Absorbs large axial movements without squirm. Eliminates main anchors. Minimum guiding required for externally pressurized expansion joints Heavy duty construction for bellow protection. The Externally Pressurized Expansion Joints provide very low turbulence to f the flowing medium due to the fact that the internal surface of pipeline itself works as the liner for this expansion joint. As the thermal expansion in externally pressurized expansion joints occur the bellows element brining the internal guide rings closer reducing the gap between them and then medium can flow through this joints as if it were not there.
