Hyspan Barco Ball Joints

Barco Ball Joint

Let Dannenbaum LLC help you with your Hyspan Barco Ball Joint selection. With a unique design, the Hyspan Barco Ball Joints can be disassembled for seal replacement, inspection, or other maintenance issues with a resulting product that lasts a lifetime. 
The Hyspan Barco Ball Joints absorb pipe movement for applications ranging from steam and hot water pipe expansion, tank and building settlement, seismic isolation, wave motion compensation on oil platforms and drill ships, solar panel movement, oil well riser expansion and safety relief valve escape piping.
Hyspan Barco ball joints are commonly used in steam hot water heating systems due to their safety and reliability. When used in sets of two or three they absorb thermal expansion or contraction by the Off-Set method of lateral displacement. The ball joints are installed in pipe run or loop oriented perpendicular to the movement. Main anchors are not required as the design of ball joints reacts pressure thrust, and the flex torque reaction force is moderate.



Hyspan Barco ball joints are used extensively for shipboard applications including oil platforms and drill ships. They are designed and qualified to ASME Class 2500 through 8" NPS, and Class 900 through 12" NPS. Fire tested to API 6FA, they meet ASTM F1298 shipboard piping specifications, and are approved by ABS Americas and Lloyd's register.



Type N Style I Hyspan Barco Ball Joints have evolved from the original ball joints, developed by Barco in 1908 to distribute steam from locomotives to passenger cars for heating. The Type N Style I was developed in 1960. Since that time thousands of Style I joints have been installed in steam, hot water and chilled water distribution systems, used to absorb tank and building settling, used for seismic isolation and many other piping applications to compensate for expansion or to add flexibility to the system. Type N Style I joints are available from 2 1/2" through 30" with Hyspan Barco proprietary Compound 11 composition seals or Compound 24 glass filled Teflon® seals. Type N Style I joints have a bolted retainer that permits seal adjustment or disassembly for maintenance.



Type N Style II, III & III-V ball joints are designed with injected graphite flakes with synthetic oil carrier, Grafoil® Flexible Graphite, that provides lubrication in addition to sealing. Grafoil® combined with a variety of high strength bearing materials results in increased temperature and pressure ratings. Seal options include Hyspan Barco Compound 11 non-metallic composition material, Number 21 ductile iron, Number 39 Alloy 625 high nickel stainless steel and Number 45 chrome-moly steel.



All Type N Style II, III & III-V ball joints permit repacking with Grafoil® after installation. Packing of Type N Style II ball joints is accomplished with the system pressure removed and the installation of a Recharge Cylinder. The Recharge Cylinders are a permanent part of Type N Style III & III-V thus permitting repacking with the system operating. The Style III-V has the added benefit of a Safety Valve to completely isolate the system pressure.

Ball Joint
As a result of their ability to react pressure thrust and absorb rotational and torsional motions, ball joint are used for tank and building settlement, seismic isolation, solar arrays, and piping displacement from wave motion. Hyspan Barco ball joints are approved by Factory Mutual System for fire protection systems, and have been tested to 8.3 seismic simulation.
