Welcome to Starflex Bellows 

metallic expansions joint it possible to simulate the behavior of a pipe expansion joint accurately under several load cases. Prediction of burst pressure, trust-force, stiffness response and radial expansion are possible. expansion bellows parameters will be investigated at different pressure levels for a given expansion joint design. metallic expansions joint.

metallic expansions joint The resulting force-displacement diagram for axial loading is given in the metallic expansions joint. First of all, the stiffness of the expansion joint is different in tension than in compression. This is most noticeable for the uninflated expansion joint which is stiffer in tension expansion bellows

fabric expansion joint explanation it the geometry of the expansion joint. Second, the stiffness of the expansion joint increases as the pressure with which the expansion joint is loaded is increased. Further, it can be seen that the reaction force for zero displacements is not equal to zero. This is due to the so-called trust-force of the expansion joint. fabric expansion joint.

When a piping system without expansion joints is pressurized, the system will not move because the pipe is countering the force in tension.

When an unrestrained expansion joint is introduced in the network, the force tends to pull the ends away from the expansion joint causing damage to itself and the pipe. dismantling joint price. expansion bellows.

fabric expansion joint This pressure thrust must be contained with either main anchors or restrained expansion joints designed to carry pressure thrust loads. The main anchors must be able to resist the pressure thrust force and a small amount of force due to the deflection of the bellows. dismantling joint price.

metallic expansion bellow The addition of tie rods to a Single Bellows Assembly adds design flexibility to a piping system. The tie rods are attached to the pipe or flange with lugs that carry the pressure thrust of the system, eliminating the need for main anchors.

With the assembly tied, the ability to absorb axial growth is lost. Only lateral and angular movement can be absorbed with the tied expansion joint. The addition of tie rods does not eliminate the need for a well‐planned guide system for the adjacent piping.

When a Hinged Expansion Joint is used, movement is limited to Angulation in one plane. Hinged Assemblies are normally used in sets of two or three to absorb large amounts of expansion in high-pressure piping systems.

Only low spring forces are transmitted to the equipment. The hinge hardware is designed to carry the pressure the thrust of the system, and oftentimes, used to combat torsional movement in a piping system. Slotted Hinged Expansion Joints are a variant of the standard Hinged Expansion Joints that allow axial and angular movement.
