Absorbs large lateral movements while tied to restrict pressure thrust - Requires only light anchors and minimum guiding Elbow Pressure Balanced Elbow pressure balanced pipe expansion joints are a combination of several types. Large amounts of lateral deflection is a function of the amount of angulation each bellows can absorb and the distance between the bellows - Angular rotation - Usually the most economical tied unit- Can be displaced laterally in any direction- With overall tie rods, it absorbs all growth of piping within pipe expansion joint- Tie rods can be designed to restrict and control motion, support weight- Can absorb external axial movement if it is not essential to function as a tied unit- Requires 9.
Universal The universal pipe expansion joint consists of two bellows separated by a pipe section or spool.Īxial movement. Pick the Right Metallic Pipe Expansion Joint for your Application.īelman is a globally recognised supplier of Engieered Expansion joints and metallic expansion bellows sized DN 25 -12000.ĭeflects in any direction - Usually provides the most economical pipe expansion joint design- Readily applicable to long and straight piping runs- Simplest construction and minimum delivery time- When Internal Guide is installed, it insures proper initial alignment of pipe expansion joint- Absorbs thermal expansion or contraction of piping systems and equipment where proper guiding and anchoring is feasible- Isolates high frequency and low amplitude equipment vibrations from piping and duct systems- Seals piping penetrating bulkheads, containment vessels, etc.- Minimizes thermal loading on machinery and vessels. Absorbs small amounts of lateral, axial, and angular movements. Single A single pipe expansion joint is simply a bellows element with end connections. In some cases, the pressure thrust of a pipe expansion joint must be restrained by the use of tie rods, hinges or gimbal while allowing the bellows to move through its design deflections. The thermal movement required can be axial, lateral or angular. Metal pipe expansion joints can withstand the design temperatures, pressures, as well as, provide the capacity necessary to absorb thermal growth of the piping system. Each type has advantages and limitations that can provide flexibility, load reduction, structural integrity and reliability required in a piping system. Bellows offers all types of metal pipe expansion joints.
