Product Description

Type N Style II, III & III-V ball joints combine the inner and outer seals that are common to all Hyspan Barco ball joints with injected graphite flakes with synthetic oil carrier, Grafoil® Flexible Graphite packing. This combination allows the use of a wide variety of high strength seal materials with the lubrication and high temperature sealing capability of Grafoil®.

Technology & Advantages

The ball sealing surface of Type N Style II, III, & III-V ball joints is protected with two mils of chrome plating consisting of one mil of hard chrome over one mil of crack free chrome, and baked-on molybdenum disulfide lubricant coating.

Type N Style II ball joints can be repacked after installation in the system if necessary. Type N Style III and III-V ball joints can be repacked under pressure. All configurations can be completely disassembled for maintenance.

Type N Style II, III & III-V ball joints are used in steam and hot water distribution systems, chemical and petroleum plants, oil exploration drilling ships and platforms, and many other critical installations. All standard configurations are warranted for five years.

Higher pressure designs and designs conforming to the ASME code are available as Hyspan Barco ASME Class Ball Joints.

Type N Style III ball joints have been fire tested in accordance with API 6FA and approved by ABS Americas and Lloyd’s Register for shipboard applications.

Design and Data

Flex Torque

Flex torque is the moment (ft.-lbs.) at break-a-way to angularly displace a ball joint. Because the pressure thrust is reacted by the seals the flex torque is a function of pressure as illustrated by the adjacent graphs for Number 19, 21 and 39 seals.

The values given are for steam service. For water or oil service the torque values are 45% less.

Seal Descriptions and Pressure Temperature Ratings

Seal Number 19

Compound 19 is a pressure molded proprietary seal compound recommended for general purpose applications for steam, hot water and oil systems. Compound 19 has the highest pressure/temperature ratings of the available non-metallic seal materials.

Rated for service at temperatures from -50° F to 525° F.

Seal Number 21

Compound 21 seals are cast ductile iron and precision machined. The ductile iron combined with the chrome plated sealing surface of the ball provide a low friction long life seal.

Rated for service at temperatures from -20° F to 650° F with standard materials of construction.

Seal Number 39

Compound 39 seals are machined from Alloy 625 high nickel stainless steel. Alloy 625 has very high strength combined with exceptionally high corrosion resistance.

>Number 39 seals are normally used in Type N packed ball joints made from special materials such as stainless steel and high chrome steel alloys. The temperature/pressure ratings are dependent on all of the materials used for construction .

Seal Number 45

Compound 45 seals are machined from ASME A-182 F11 chrome-moly steel forgings. Alloy F11 is a very high strength steel which can be used for higher temperature applications.

Number 45 seals are normally used in Type N packed ball joints made from special materials flange including high chrome steel alloys. The temperature/pressure ratings are dependent on all of the materials used for construction.

Installation and Maintenance Procedures

Type N Style II

Installation Recommendations

  1. The media flow direction can be from either end of the ball joint except for liquids with suspended solids, then flow should be from ball end to casing end.
  2. In vertical installations, ball joints should be installed with the ball end down to prevent foreign matter from collecting between neck of ball and retainer
  3. Do not loosen the ball joint retainer during installation, or utilize ball joints as Unions.
    Each joint is factory preset and tested before shipment. LOOSENING OF THE BALL JOINT RETAINER IS NOT RECOMMENDED. If the retainer must be loosened, loosen bolted retainers by loosening the bolting 1/4 revolution maximum using a standard crossing pattern. Retightened using the procedure outlined in Paragraph 7(j) of the Maintenance Instructions below. OW 1500 Style II ball joints have threaded retainers. Loosen the retainer 1/4 revolution maximum and retighten the same rotation.
  4. Use CAUTION PREHEATING, WELDING, OR POST WELD HEAT-TREATING ball joints into the line. Excessive heating of the sealing area may cause leakage.
  5. Protect the exposed ball surface from weld splatter, and prevent dirt and debris from .
    collecting around neck of ball.
  6. Although ball joints can be rotated or twisted around the centerline, they are designed to absorb motion by the Offset Method that utilizes angular flex to provide the required movement. Consult a Hyspan Barco sales representative or contact Hyspan by email at websales@hyspan.com if an application involves extensive rotating motion.

Style II Recharge Cylinder

General Warning

Type N Style II, OW 1500 Style II and ASME Class Hyspan Barco Ball Joints are not designed for maintenance to be performed while the system is pressurized. DO NOT PERFORM ANY ADJUSTMENTS TO A BALL JOINT THAT IS PRESSURIZED.

Maintenance Instructions

To correct leaks or perform routine maintenance.

In order to repack Type N Style II, OW 1500 Style II and ASME Class Hyspan Barco Ball Joints a recharge cylinder (Part Number 10-64416-43) and packing pellets available in reload kits of 13 pellets (Part Number 10-64715-00) will be required. These products are available from an authorized Hyspan Barco representative or contact Hyspan at websales@hyspan.com.

  1. Relieve the internal pressure and allow ball joint to cool to a safe temperature for handling.
  2. Remove all of the charging port plugs.
  3. Prior to installing the recharge cylinder remove the ram screw and insert one (1) packing pellet. Replace the ram screw and rotate until a small amount of sealant has been forced out of the tip of the cylinder. Apply thread lubricant to recharge cylinder threads, and thread the recharge cylinder into the one of the ball joint ports.
  4. Inject sealant into the port by turning the ram screw until sealant is forced from the adjacent port. If necessary add additional packing pellets. Do not exceed 150 ft.-lbs of torque on the ram screw.
  5. Remove the recharge cylinder. Sealant should expand from the port. Replace the port plug.
  6. Thread the recharge cylinder into the adjacent port and repeat steps 5 and 6 until all of the ports have been charged and the plugs replaced. Be certain that all of the plugs have been replaced with the threads fully engaged and tightened prior to pressurizing. If leakage still occurs the ball joint can be disassembled for maintenance.
  7. TO DISASSEMBLE the ball joint for maintenance it must be removed from the system.
    1. Disassemble the joint by removing the retainer.
    2. Inspect the inner seal for wear: The inner seal is seldom worn enough to require replacement.
    3. Clean and inspect ball surface carefully. Replace the ball if it is worn, scored or pitted.
    4. Replacement balls, seals and packing are available from an authorized Hyspan Barco representative or contact Hyspan at websales@hyspan.com. Be certain to dispose of discarded seals and injected packing properly.
    5. To reassemble, coat the surfaces of the seal(s) and ball with a light coat of assembly lubricant. For service over 350º F use molybdenum disulfide based lubricant.
    6. If the inner seal has been removed, install it in the case with the concave surface out by tapping it in place evenly with a soft mallet.
    7. Slide new outer seal over extended end of ball with the concave surface mating to the convex surface of ball.
    8. Replace ball into casing.
    9. Tap the new outer seal evenly with plastic or rubber hammer into casing around ball.
    10. For bolted retainers tighten retainer bolting to the following factory torque settings using a standard crossing pattern.
