Hyspan-Barco ball joints provide a safe, effective means of accomodating pipe movements in systems where thermal expansion, shock, seismic, and torsional forces exist. The simple, precision ball-in-socket design handles 15º to 40º angular flex and 360º rotation. Ball joints can provide additional flexibility in areas where stress concentration exceed design limitations. Ball joints are an integral part of the piping system, providing complete flexibility with the integrity and reliability of solid pipe. Hyspan-Barco ball joints have been used succesfully in continuous service up to 2000ºF and 2500 psig. They serve in demanding applications such as:\r\n\r\nTransmission of HP/HT gas, water and liquids\r\nAlternative to pipe loops\r\nProtect piping and tank nozzles\r\nHandle high pressure steam and gases at well heads\r\nProtect compressor and pump connections from stress\r\nDistribution and gathering lines\r\nPivot points on high pressure stationary equipment\r\nProtect safety relief valve nozzles from shock and stress\r\nProtection of turret swivels on FPSO's\r\nConvenient, flexible connections for well head testing\r\nPlatform and subsurface piping\r\nRiser piping\r\nPiggable pipe lines\r\n\r\nThey have been tested to 8.3 seismic simulation, API 607 fire tests, meet ASTM F1298, ASME B31.1, B31.3 and ABS approved for marine piping.\r\n\r\nHyspan-Barco ball joints are available in pipe sizes 1/2" to 48", in steel, alloy and N.A.C.E. materials. They are maintenance free, have redundant sealing, and a projected life up to 40 years or more.
