Steel expansion joints are flexiblepipe connection elements and areused in a variety of industrial applica-tions:
■ Machine engineering■ Domestic industry■ Chemical industry■ Process plant engineering■ Gas and water supply■ Exhaust technology
STENFLEX® steel expansion jointshave served with distinction for morethan 45 years. They are the preferredflexible pipe connection elements ofchoice in manufactured appliances,machinery, apparatus and piping en-gineering.Constant further development and in-novations update our product rangeto meet the needs of current andchanging markets, and fulfil the re-quirements of industry in regard to:■ Operating safety■ Reliability■ Pressure and temperature
resistance■ Vacuum stability■ Flexibility■ Impermeability■ Corrosion resistance■ No maintenance■ Long service life
The large-scale industrial manufac-ture of steel bellows, constant controlof compliance with all manufacturing,business and quality processes in linewith EN ISO 9001:2008 and decadesof experience in the development andmanufacture of steel expansion joints:all this guarantees a uniform productof the highest standard. It underlinesthe STENFLEX® Quality Claim.
Our expertise in expansion joint engi-neering is reflected in the long servicelife and consequently in the high op-erational reliability of our steel expan-sion joints, thanks to the excellentproduction functionality and quality.
Purpose
For decades our steel expansionjoints have been used in a wide varietyof applications, and guarantee trou-ble-free operation on-site.
STENFLEX® has been assessed andapproved as manufacturer of steel ex-pansion joints, on the basis of ADnorms of the Pressure Equipment Di-rective and international standards.Calculations are based among otherfactors, on AD 2000-B12, DIN EN14917 and EJMA. STENFLEX® steelexpansion joints have been certifiedby numerous classification, and ac-ceptance societies, and bear the CEmark.
Our engineers together with our R&Ddepartment are always available fortechnical consultation, and ready tohelp in solving specific applicationproblems at any time.

STENFLEX® steel expansion jointsvary according to the following crite-ria:■ type (universal/lateral/angular ex-
pansion joints)■ pipe connection type (flange, weld-
ing end or threaded connection)■ material quality of the bellows (rat-
ed to the media transported in thepipes)
■ bellows structure (rated to themovement, pressure and tempera-ture load)
Our expansion joints are deliveredready for installation. STENFLEX®manufactures expansion joints innominal widths DN 15 – DN 2800 andfor nominal pressure rates PN 1 - PN25. A wide range of materials is used,with temperature resistance from–196 °C to +900 °C.
Lateral expansion jointsStructure:Steel bellows with laterally movable restraints and flanges or welding ends. Movement absorption:Lateral shift of the expansion joint is possible. The restraint absorbs axial reac-tion force and relieves the pressure on the pipe's fixed points. Lateral expansionjoints, with two bellows and a connecting pipe are used to absorb large move-ment.Fixed points:Only light fixed points are required to absorb lateral movement and frictionforce.
Axial expansion jointsStructure:Steel bellows with connection parts (flange, welding end or threaded connec-tion). Movement absorption:Axial shift, and slight all-round movement of the expansion joint is possible. Ax-ial expansion joints with two bellows are used to absorb larger movement.Fixed points:Robust pipe fixed points and correct pipe routing are necessary to absorb theaxial forces.
Angular expansion jointsStructure:Steel bellows with hinge restraint and flanges or welding ends. The rotating axis ofthe hinge restraint is in the middle of the bellows. Movement absorption:Angular movement of the expansion joint is possible. The angular joints regu-late a defined angular movement, absorb axial reaction force and relieve thepressure on the pipe's fixed points. We differentiate between angular expansion joints with a hinge (bellows angularmovement guided on one plane) and angular expansion joints with a cardanhinge restraint (bellows movement guided on two planes).Fixed points: Only light fixed points are required to absorb angular movementforce and friction force.
Together with the standard and basicversions featured in the catalogue,special versions can also be devel-oped and produced on request, forspecial operating conditions or spe-cial structures.
Connection parts (that deviate fromDIN) such as EN, ISO, ANSI, VG, SAEstandards etc. are also available.
STENFLEX® steel expansion joints arerated theoretically using state-of-the-art computing techniques (which in-clude the Finite Element Method).They are optimized under experimen-tal conditions. National and interna-tional calculation standards are usedto rate the bellows.Our development engineers use themost up-to-date development toolsthroughout the development stage tovalidate the construction process interms of form, function and installa-
tion. Hence we can offer our cus-tomers the following advantages:

Material qualitiesSTENFLEX® expansion joint bellowsare manufactured from top qualitysheet metal. Different material quali-ties are used to cover the many oper-ating conditions in various industrialapplications.
StructureSTENFLEX® steel bellows are avail-able in a variety of structures and ver-sions. The steel bellows is the flexibleelement of every expansion joint. Itmust fulfil the requirement for goodmovability with simultaneous pres-sure resistance.
Variable parameters (wall thickness,number of plies, convolution geome-try, number of convolutions) deter-mine the pressure resistance, move-ment absorption and spring rate (self-resisting force) of the bellows. One-ply, two-ply and multi-ply bellows aremanufactured from various materialswith different wall thicknesses.
Our calculation methods ascertain thestability limits. The ability to withstandbuckling is the prime criterion forsmaller bellows diameters, whereas inlarger bellows diameters it is convolu-tion stability.

Rating, service life
Steel bellows, as a rule, are rated for atemperature of +20 °C, the nominalpressure and a load of 1000 load cy-cles.
One load cycle refers to the proce-dure beginning at zero position, fromwhere the expansion joint moves tothe maximum elongation (positive)position, back through the zero posi-tion to the maximum compression(negative) position, and back to thezero position.
Together with the tolerable operatingconditions
■ pressure■ temperature■ movement■ number of load cycles
the following parameters can also in-fluence the service life of expansionjoints:
■ corrosion■ high-frequency oscillations■ sympathetic vibration■ pressure shocks■ temperature shocks■ incorrect installation
Corrosion can be caused by incorrectselection or combination of materials,conveyance of aggressive media andinappropriate cleaning with chemicalagents.
High-frequency oscillations and sym-pathetic vibration must be avoided byall means, because this will result infatigue failure/fracture.
Pressure and temperature shocksmust be avoided. It is important not toexceed the permitted maximum val-ues.
Incorrect installation can be prevent-ed by compliance with our installationand assembly instructions.
In the case of unrestrained expansionjoints, the absence of fixed points cancause the pipeline to shift. This usual-ly destroys the expansion joint.

Steel expansion jointsGeneral description of steel expansion joints
STENFLEX® steel expansion jointscan be provided with the followingaccessories:■ Internal guide sleeve■ Guide sleeve■ Protective cover
Internal guide sleeves
Internal guide sleeves can be insertedor welded into the expansion joint. Asa rule they are made of stainless steel.Internal guide sleeves are required tohandle higher flow speeds (see dia-gram) and the resulting possible reso-nance in the bellows. Also to deal withturbulence as a result of deflection inthe direction of flow (e.g. behindpumps, valves, T-pieces, pipe bends).
Even under these conditions, the in-ternal guide sleeve is intended toguide the medium turbulence freethrough the convoluted bellows.
An internal guide sleeve also providesthe bellows with reliable protectionfrom abrasion by the medium. In thiscase the internal guide sleeve musthave thicker walls.
Internal guide sleeves have proven successful as protection for the bellows at flowrates above the curve. The data are of indicative nature.

Guide sleeves
Guide sleeves stabilize the expansionjoint in its axial movement and pre-vent it from buckling. As a rule, guidesleeves are made of thick-walled,stainless or unalloyed steel.
Axial expansion joints with two bel-lows are provided with guide sleevesin the factory, as a rule with a tele-scopic design.
Expansion joint guide sleeves do not supersede pipe guide bearings.

Protective covers
Protective covers are used to protectthe bellows from damage during in-stallation and operation. The pipes,fitted to the outside, protect the bel-lows reliably from splashes of weldingmaterials or other mechanical influ-ence. As a rule protective covers aremade of stainless or unalloyed steeland can be fitted on the outside bothover the flanges and between theflanges.
