Metal Bellow

Product Details:

Metal expansion joints (MEJ) also called compensators or metal / metallic bellow. An expansion joint/bellow element employed in a piping system is an assembly of generally more than one convolute in series with the shape of the convolution designed to withstand the internal pressures, Thermal expansion, mechanical vibrations of pumps, draft fans, compressors, turbines, motors, vessels and other plant components, but flexible enough to accept axial, lateral, and angular deflections. They consist of one or more metal bellows. Metal expansion joints have to be designed according to rules laid out by EJMA (expansion joint manufacturing association).For Fabric & Rubber expansion joints there are guidelines and a state-of-the-art description by FSA (fluid sealing association). Expansion joints are differentiated according to the three basic types of movement: axial, angular and lateral expansion joints. The central component of each expansion joint is the metal bellows .Due to its shape and thin wall, acts like a spring. The bellows however has to meet the following basic criteria to qualify for its use as an expansion element.

It must:

• Withstand the operating and test conditions (pressure, temperature).
• Ensure corrosion resistance.
• Provide sufficient flexibility for the purpose.
• Include sufficient squirm stability.

Movements & Spring Rates: There are four basic movements that can be applied to a bellows. These are Axial, Lateral, Angular and Tensional. Respective spring rates are - Axial spring rate, Lateral spring rate, Angular spring rate. The spring rate of a bellows is entirely dependent on bellows geometry and material properties.

Axial Movement (+/ MM): Axial movement is the change in dimensional length of the bellows from its free length in a direction parallel to its longitudinal axis. Compression is always expressed as negative () and extension as positive (+). The units for axial spring rates displayed in N/mm.

Lateral Movement (+/ MM): This relative displacement of the two ends of an Expansion Joint perpendicular to its longitudinal axis. This has been referred to as lateral offset, lateral movement, parallel misalignment, direct shear or transverse movement.

Angular Movement (+/ Degrees): This displacement of the longitudinal axis of the Expansion Joint from its initial straight line position into a circular arc.

SS bellow expansion joint setups are a creative alternate option for pipe and pipeline industries. These types of joints can easily be applied to the crude Oil & Gas, Paper & Pulps, Sugar plant, Chemical plant, Power sector and also Petrochemical sectors and also in several other fields. The most common application for a stainless steel single bellows axial expansion joint is to absorb axial movements of a straight pipe between primary anchors. This SS axial expansion joint should be placed near one anchor and guides should be utilized to ensure proper alignment and movement. 

Metal expansion joints are beneficial portions of the pipeline system. We provide bellow expansion joint in a wide variety of materials ranging from Austenite series .i.e, SS 300 Series (SS304L, SS316L, SS321, etc.) to special alloys like Inconel, Hastelloy, Monel, etc. In pipelines expansion bellows are utilized to compensate length changes, which generally happen in pipelines from temperature modifications. In addition to this, they are capable of reading and absorbing vibrations generated by pumps, motor, compressors or wind turbines.
