API

Command Energy is a manufacturer of Standard API Connections and provides American Petroleum Institute (API) certified connections in a variety of pipe lengths, diameters and steel grades licensed for:

API Specifications

  • 5DP (ISO 11961:2008)
  • 7-1 and 7-2 (ISO 10424-1:2004 and ISO 10424-2:2007)
  • NS-1

 

In addition to industry API tool joint connections, Command Energy offers its advanced CET™ and CDS™ connections when higher torque is needed. 

CET™

Applications

  • Best in class performance and optimized operational characteristics required of high torque connections to drill the well designs of today
  • Available on all sizes of drill pipe, heavy-weight drill pipe and collars for use on work strings, slimhole drillstrings and frac strings

Features and Benefits:

  • 5 ¼ turns to make-up is the fastest of any high torque connection
  • 170% - 200% of the torsional strength of API connections
  • Provides increased torque with the addition of an optimized secondary torque shoulder
  • Available in 2 3/8 - 7 5/8” sizes
  • Reduces the amount of repairs required to less than 1% per well drilled
  • Cuts rig NPT during tripping operations by 50% over competitive high torque connections
  • A smooth ID through the connection, which can be made with smaller OD’s and larger ID’s than standard connections while maintaining higher torque capacities 

CDS™

Applications

  • Torque advantage over API and runs easier than the competition, providing the optimum solution to reach total depth as fast as possible.
  • Available drill pipe, heavy-weight drill pipe and collars in all sizes from 2 3/8”-12”.drillstrings and frac strings.

Features and Benefits

  • Fully Interchangeable with API and some DS connections
  • NS-1 approved rotary shoulder connection
  • Provides increased torque with the addition of an optimized secondary torque shoulder
  • A smooth ID through the connection, which can be made with smaller OD’s and larger ID’s than standard connections while maintaining higher torque capacities
  • Extended by being able to wear to a smaller OD while maintaining a torsional capacity greater than 80% of the drill pipe tube
  • The CDS™ connection can be made up with API numbered connections and some other available double shoulder connections.

Increased Wear Resistance:

  • The CDS™ connections life is extended by being able to wear to a smaller OD while maintaining a torsional capacity greater than 80% of the drill pipe tube.
  • The minimum OD varies with what grade and weight the drill pipe is. As an example a 4” G105 15.7 lbs/ft drill pipe with 5 ¼” x 2 7/16” NC40 connections has a premium class minimum OD of 5”.
  • The same drill pipe with a CDS™40 connection will have a premium minimum OD of 4 3/4”.
