scope:

This specification establishes the requirements for hydraulic swivel joints (see 6.1).

Hydraulic swivel joints covered by this specification shall be the following types and classes, as specified:

Type I −65° to +160° F (−55° to +70° C) temperature range Type II −65° to +275° F (−55° to +135° C) temperature range Type III −65° to +450° F (−55° to +232° C) temperature range Class 1500 psi Where the nominal cut out pressure at the main pressure controlling device is 1500 psig Class 3000 psi Where the nominal cut out pressure at the main pressure controlling device is 3000 psig Class 4000 psi Where the nominal cut out pressure at the main pressure controlling device is 4000 psig Class 5000 psi Where the nominal cut out pressure at the main pressure controlling device is 5000 psig

Hydraulic swivel joints covered by this specification shall be the following styles:

Style a. Plane swivel: Able to swivel (rotate) in a single plane only.

Style b. Angular misalignment swivel: Able to swivel and compensate for a conical axial motion of 5 minimum to 7.5 maximum degrees (total axial motion of 10 to 15 degrees).

Style c. Other styles: Other swivel requirements, or other styles of swivel joints, such as joints incorporating sliding features, are covered by this specification.

Swivel joints passing the first article inspection tests to specific type, class and style shall be considered as acceptable to those types and classes of the same style with lower requirements.
