expansion joint webinar registration to attend free live technical webinars - u. s. bellows, inc .
a houston - based expansion joint manufacturer, u. s. bellows, inc. has acquired all bellows assets of the former lortz manufacturing company. this acquisition includes the fabrication equipment, expansion joint and bellows drawings, design software, customer lists, and all engineering history and other historical data associated with lortz manufacturing .
register to attend a free live webinar featuring technical information about metallic and fabric expansion joints and stock bellows .
the expansion joint equipment was transferred from bakersfield, california to the u. s. bellows facility in houston, texas. the additional machines will be incorporated into the current u. s. bellows location, and therefore significantly expand u. s. bellows’ ability to provide high quality expansion joints more quickly and efficiently to customers around the world .
u. s. bellows, inc. has been designing and manufacturing engineered pipe expansion joints for the industry since the 1960s. today, u. s. bellows consists of manufacturing resources of rm engineered products of ladson, sc (acquired in 1995) and ketema - u. s. bellows, inc. of san diego, california (acquired in 1997) .
u. s. bellows will be hiring and relocating some of the former lortz welders and other employees to their manufacturing headquarters in houston. besides expansion joints and bellows, the company also offers field services and quick - turn service for emergency situations. u. s. bellows has over 50 years of experience and is prepared to provide expansion joint repair, refurbishment or replacement for past lortz - supplied expansion joints .
don' t forget to register for our live webinar 10 am on thursday june 14th. the presentation will be on fabric expansion joints by u. s bellows
the universal pipe expansion joint consists of two bellows separated by a pipe section or spool. the primary purpose of this arrangement is to have a unit which will accept large amounts of lateral deflection. the amount of lateral deflection they can accept is a function of the amount of angulation each bellows can absorb and the distance between the bellows. for a given bellows element, the amount of lateral deflection capability can be increased or decreased by simply changing the length of the center spool. in this catalog three standard overall lengths are given with their lateral movement capability. if the piping problem requires greater capability, then the overall length can be increased to suit. read more ...
u. s. bellows is a proud member of the expansion joint manufacturer' s association (ejma), since 2002 with representation on both the technical and management committees .
additionally, u. s. bellows has focused expertise in the design and engineering of pipe expansion joint products for particular vertical markets and applications. these applications include the following :
u. s. bellows, a member of the expansion joint manufacturers association (ejma), supplies an assortment of metallic and fabric expansion joints for a wide variety of applications .

quality control: additionally, u. s. bellows does extensive physical testing to prove designs. each bellows and pipe expansion joint unit goes through in - process quality control using a system of travelers. final in - house inspection and testing is performed prior to shipping, based on customer requirements. u. s. bellows has performed a variety of tests on pipe expansion joints ranging from x - ray tests and hydrotests to helium leak tests (using a mass spectrometer). our manufacturing shop also has asme section viii code certification for jobs requiring code certification .
u. s. bellows, inc. is available on a 24 x 7 basis to fulfill any emergency requirements that might arise. for the quickest response, please fill out the emergency request form .
u. s. bellows, inc. has been designing and manufacturing engineered pipe and duct expansion joints for the industry since the 1960s and has been a proud member of the expansion joint manufacturer' s association (ejma) since 2002 .
this expansion joint will not resist any deflections with any force other than the resistance of the bellows, which is a function of the spring rate times the deflection amount. it is incapable of resisting the pressure thrust along its axis, which is the product of the pressure times the effective, or cross sectional, area of the bellows. large diameter units, even with low pressures, can generate very large axial pressure thrust forces, which must be reacted by main and directional anchors. otherwise the expansion joint will extend with disastrous results .
this pipe expansion joint is simply a bellows element with end connections. regardless of accessories, such as liners and covers, it will deflect in any direction or plane that the bellows will. it is the least expensive type, but requires that the piping be controlled as to the direction of the movements required of the unit. the pipe expansion joint should not be expected to control the movement of the pipe. if the piping analysis shows that the pipe expansion joint must accept axial compression, then the piping must be guided and constrained so that only that movement will occur. read more ...
engineering & design: engineering and design is done per ejma equations as well as per the latest revisions of the asme b31. 3, asme b31. 1, and asme section 8, division 1. design calculations are performed using design software developed in - house and calculations are further checked using hand calculations. u. s. bellows also has full in - house finite element analysis capabilities and we often use this methodology to prove designs. u. s. bellows offers 24 - hour service and we have often provided emergency field service during installation or plant shutdowns. our history in pipe expansion joints goes back a long way: our founder first wrote a fortran program to design expansion according to koppe and sair' s early paper on pipe expansion joint design circa 1975 .
since deflections are usually the result of piping thermal expansion, and universal expansion joints are usually long, our units are designed so that the thermal expansion of the entire unit' s length is accepted as compression by the two bellows elements. in this way, the overall length of the unit does not change when the piping is heated. the standard units in this catalog have all been designed to accept the thermal expansion of their length when the temperature is up to the design temperature shown .
