Hyspan Barco Ball Joints provide a method of absorbing 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.
The unique design of Hyspan Barco Ball Joints allows disassembly for inspection,
seal replacement or other maintenance resulting in a product that lasts a
The Hyspan Barco Off-Set® Method utilizes two or three ball joints installed in
a leg of the piping or a loop with the motion perpendicular to two ball joints
installed in tandem. Two ball joints are satisfactory for most applications - a
third joint may required for large movements.

Hyspan Barco Ball Joint Applications
Details the many uses of ball joints in piping systems. Includes recommended
layouts with methods of calculation of motions, forces and moments.
Oil Field Steam Injection
Scissor linkage incorporating ball joints designed to absorb well head growth
for steam injection wells in oil fields.
Solar Panel Connections
Ball joint configurations for the heat transfer oil piping connecting the main
header and crossover between mirrors for parabolic trough solar panels. Allows
panels to rotate to track the sun.
Recommended ball joint installation for piping connections to tanks to
compensate for displacement resulting from soil conditions.
Standard Catalog Ball Joint Designs
Hyspan Barco Ball Joints are available in standard and custom configurations
1/2" through 30" nominal pipe size. The following configurations are available
that will meet most requirements. Contact
websales@Hyspan.com for additional sizes through 48" or special design
Type N Style I Ball Joints
Type N Style I Hyspan Barco Ball Joints have evolved from the original ball
joints that were 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 Styles II, III & III-V Ball
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.

ASME Class Ball Joints
Class150 through 2500
Hyspan Barco ASME Class ball joints have been designed to conform to the ratings
established for ASME butt weld valves at 100ºF. Standard configurations are
available 2" through 12" NPS for class 150 through 2500.
The sealing system combines ductile iron or alloy steel with injected graphite
flakes with synthetic oil carrier, Grafoil® Flexible Graphite. Grafoil® packing
can be injected after installation if necessary.
ASME Class Ball Joints have been fire tested in accordance with API 6FA and
approved by ABS Americas and Lloyd's Register for shipboard applications.
OW1500 Style II and III-V Ball Joints
OW1500 Ball Joints are designed for 1500 psig and temperatures to 650ºF.
They are commonly used to compensate for riser expansion on oil field wellheads,
to compensate for solar panel rotation and other high-pressure applications.
OW1500 joints have ductile iron seals in combination with injected graphite
flakes with synthetic oil carrier, Grafoil® Flexible Graphite. OW 1500 ball
joints are designed to be repacked in service.
Type Standard Series, Type 600, Type 14000: Consult factory for
Standard Series Ball Joints are made from ductile iron or wrought steel
is sizes ranging from 1/2" through 2". Straight and 90º elbow configurations are
available with female pipe threads. Three seal compounds are available - Hyspan
Barco proprietary Compound 11 composition seals, Compound 23 Teflon®, and
Compound 24 glass filled Teflon®.
Standard Series Ball Joints are ideally suited for machinery applications as an
alternative to hose assemblies and for seismic isolation.
Series 3500 IS In-Line
Seismic Expansion Joint
Hyspan Barco ball joints are combined with Hyspan
Series 3500 Externally Pressurized Expansion Joints to provide standard
products 2" through 12" NPS designed for +/-6", +/-12", +/-18" or +/-24"
combined axial and lateral movement. They are designed as direct connections in
vertical or horizontal pipe runs, and do not require a change of direction.
