Ejma Bellows Software Solutions

EJMA The Expansion Joint Manufacturers Association, Inc. Is an organization of established manufacturers of metal bellows type expansion joints. EJMA was founded in 1955 to establish and maintain quality design and manufacturing standards. These combine the knowledge and experience of the association's Technical Committee and are available to assist users, designers, and others in the selection and application of expansion joints for safe and reliable piping and vessel installation. Are experienced and knowledgeable manufacturers that have demonstrated many years of reliable service to industry. As reputable manufacturers, EJMA members are the best source for product value, design, and service. For a further explanation of ways EJMA members give you the edge on quality, EJMA also functions as a forum for discussion and correlation of technical information from members and outside sources including engineering societies, universities, industry, and government.

Selection software for Expansion Joints Configurator Solutions makes selection & configuration software for manufacturers of Expansion Joints. Broad features are: • Models are selected based on axial, angular, lateral movement calculated or entered by user. Hast rekha gyan pdf in hindi. • Forces and moments acting on anchors can be calculated based on model selected. • Stress induced in bellows, fatigue life & theoretical spring rate can be calculated.

• Selection of material based on type of fluid, temperature & pressure is possible. All calculations are based on EJMA standard. Let’s take a look at the features & functionality provided.

User inputs precise accepts the following inputs from the user: Fluid Data Section This section allows a user to select the Fluid, Flow Rate, Max Operating Pressure, Min & Max Operating Temperature & Pipe Size. Movement Section This section allows a user to specify one or more movements. • Axial – The user is able to select Axial movement. The cumulative total of Compression & Extension will be considered for Axial movement. • Compression – the user is allowed to enter value if known or else will be allowed to calculate. • Extension – the user is allowed to enter value if known or else will be allowed to calculate. • Lateral – User is able to select & enter data for Lateral movement.

• Concurrent – Concurrent option is enabled only if user selects Axial & Lateral movement. • Angular – Angular option will not be available if user has selected Axial or Lateral movement. Similarly if user selects Angular movement, Axial & Lateral movement options are disabled. User will be able to select & enter data for Angular movement in degree rotation. • Single Plane – On selecting this option, Hinge expansion joints will be filtered. • Multi Plane – On selecting this option, models of gimbal expansion joint will be filtered.

Material, Connection & Accessory Section Materials Select Bellow & Fitting materials. Connection Select appropriate connections required. Accessories Pick accessories such as Sleeve or Cover. Output Section Based on the user inputs in Fluid Data section, flow velocity is calculated. Based on user selections, various models are evaluated & eligible models are listed. EJMA Results Section EJMA Result section displays results of the various stress & force calculations performed as per the EJMA standards.

Installation Guidelines Section This section provides information about the distances between anchors, bellow & guides considering the total pipe length & the amount of forces acting on fixed anchors. Axial Calculator The user is able to select Pipe Material. The minimum & maximum temperatures entered by the user are considered. Precise calculates Thermal Expansion depending on the pipe length. Inputs required to perform EJMA calculations are: • Db = inside diameter of cylindrical tangent and bellows convolutions • t = one ply thickness • Lt = bellows tangent length • tc = bellows tangent reinforcing collar material thickness • Lc = bellows collar tangent length • Dc = mean diameter of bellows tangent reinforcing collar • Dm = mean diameter of bellows convolutions • N = number of convolutions • q = convolution pitch • rm = mean radius of bellows convolution • w = convolution height • n = number of bellows material plies.
