EXTERNALLY PRESSURIZED EXPANSIONJOINTS WITH WELDING NECKSExternally Pressurized Expansion Jointsare preferred in long pipelines in order touse less number of expansion joints usedand to reduce number of fixed points androller bearing that increase installationcosts. Resulted from the design of bellowspart that protect the axis and increasepressure resistance, risk of twisting effect isminimized and working opportunity in highpressure environments is obtained.Material SpecificationsBelow: AISI 304 Stainless SteelPipes St37 Carbon SteelOptional: Completely Stainless SteelExternally Pressurized Expansion Joint With W.Necks Dimensons And MovementsL(mm)DIAMETERExpansion 829DN640 Bar25 Bar

TECHNICAL INFORMATIONThe bellows parts of expansion joints are made of comparatively thin materials. Especially before welding around,product should be protected by means of wrapping the bellows part by a fireproof material in order to prevent itfrom clinkers or unintended impacts.Axial expansion joints are produced only to absorb axial motions. Because of this, rolling bearings over thepipelines should be placed only to allow axial movements. On turning points, only fixed bearings should be used.In order not to twist expansion joints, pipelines to be connected should necessarily be parallel during installation.Calculated expansion and contraction points should be between two fixed points. One expansion joint should beplaced between two anchored points and pretensioning should be applied as described below:Waste materials that are potentially going to block movement by going into convolutions of bellows should beremoved. Fluids that cause erosion on stainless steel like chlorine should not be used in cleaning.Expansion joints are tested 1.5 times of rated pressure. While testing pipeline, maximum test pressure should notexceed this value.Expansion joints should be protected from thermal shocks. Thermal shocks reduce expansion joint’s life cycle.Expansion lengths vary according to the temperature at the time of installation. In the table below, expansionlengths of carbon steel and stainless steel materials. If temperature at the time of installation is below or above 20 C, difference from operating temperature either added or subtracted from the value using the values within table.Example :Let us assume a pipeline installation made of carbon steel in 100 meters length carrying steam at a temperatureof 125 C. In this case axial expansion is:1. If installation temperature is 20 C : 1.26x100 126mm2. If installation temperature is 0 C :1.48x100 148mmTemperature3. If installation temperature is 35 C : 1.09x100 109mmC Proper pretensioning should be applied to expansion joints accordingto the examples below. For expansion joints with large diameters orwith welded necks, this process can be done easily by placing pulleror stretchers on welded necks.Formula :Pretensioning Value (*) 0,5 [ ΔLTmax – ΔLTmin – 0,5(-ΔL) ]Example :Material: Carbon SteelDia. of Carbon Steel Pipe: DN100 / Pipe Length: 50mMin.
