Drilling Tubulars and Accessories
Drilling Tubulars
Utilizing broad industry experience in drilling, material sciences and advanced manufacturing, Complete Tubular Products (CTP®) is creating products that meet and exceed the evolving needs of the industry. We are driving the tubular market forward through our innovative proprietary connections and drill pipe, our improved material selection and qualification, and our global support network and leading-edge inventory.
Drill Pipe:
Drill pipe is a crucial component in the process of drilling for oil and gas.It is designed to transmit drilling fluid and torque from the surface to the drilling bit at the bottom of the wellbore. Drill pipes are threaded on both ends to connect to other sections of pipe, forming a continuous string down the well. They are subject to high tension, compression, and torsional stresses during drilling operations.

Customized design to meet the application
Extensive stock available
Specs we meet and exceed: API 5DP, DS-1, NS-1, IRP1.8, etc.
Heavy Weight Drill Pipe (HWDP):
Heavy weight drill pipe is a specialized type of drill pipe used in drilling operations where additional weight is needed in the drill string to provide more force to the drill bit. HWDP is thicker and heavier than regular drill pipe, typically featuring a thicker wall, it provides additional weight and stiffness to the bottom-hole assembly. This extra weight helps to maintain vertical wellbore integrity and improve the rate of penetration while drilling.

Specs we meet and exceed: API 7-1, DS-1, NS-1, IRP1.8 etc.
Drill Collar:
Drill collars are heavy, thick-walled steel pipes used in drilling operations to provide weight on the drill bit, maintain vertical wellbore direction, and prevent deviation during drilling.
Top Drive Saver Sub acts as a sacrificial component between the top drive and the drill string, protecting both systems from wear and damage.
Configurations: Pin × Pin and Box × Pin are the most common.
Dimensions: Can be customized to meet specific rig requirements.
Optional features: Keyway slots, belled ends, slick profiles, and other design enhancements are available.
Crossover Sub is used to connect different thread types or sizes within the drill string and can also serve as a sacrificial component.
Configurations: Box × Pin, Pin × Pin, and Box × Box.
OD & ID: Typically matched to the connection sizes used in the drill string.
Length: Can be customized, or manufactured to API 7-1 (36″ OAL) or DS-1 (48″ OAL) standards.
Design options: Slick or belled (fishneck) profiles are available.
Casing Sub is used to transition from drill pipe connections to casing connections during completion operations.
Configuration: Box (drill tubular) × Pin (casing) is the most common.
Design options: Slick or fishneck profiles are available.
The pin end can be hollowed out to facilitate easier handling and make-up.
Pickup Sub is used for lifting drill string components with an elevator.
Configuration: Top cap × Pin.
The top cap and shank are typically manufactured to match the drill pipe tool joint and tube dimensions to ensure proper elevator fit. The tool joint and thread connection can be customized as required to suit the drill string or accessories being handled.
Pup Joint / Drillable Pickup Sub is used for lifting drill string components with an elevator and can also be run downhole with other drilling tools.
Configuration: Box × Pin is the most common.
Length: Typically available in lengths up to 30 ft.
Blow Down Sub is used to pump fluid into the drill string.
Configuration: Hammer Union × Box in a one-piece design, or NPT/LP Box × Box to allow use with a nipple joint.t with a nipple joint.
Circulating Sub is used to pump fluid into the drill string.
Configuration: Hammer Union × Pin in a one-piece design, or NPT/LP Box × Pin to allow the operator to use it with a nipple joint.
Lift Nubbin is used to lift drill string components using the handle on top.
Configurations: Lift handle × Pin or Lift handle × Box.
Testing: Pull-tested to verify lifting integrity.
Material: Manufactured from cast steel or machined steel billet.
Side Entry Sub is used to pump fluid into the drill string.
Configuration: Box × Pin with a side-mounted Hammer Union, machined as an integral one-piece body.
Testing: Hydraulically tested to 15,000 psi
Bit Sub is used to house a float (check valve) above the drill bit to prevent backflow.
Configuration: Box × Box. The lower box, which connects to the drill bit, incorporates a float bore.
Design options: Slick or belled (fishneck) profile.
Float Sub functions similarly to a Bit Sub but features a Box × Pin configuration, with the float bore located adjacent to the box end.
Lower Kelly Cock is installed within the drill string to allow free passage of drilling fluid without pressure loss. It is specifically designed to provide effective control of blowouts and manage mud losses.
Inside BOP (Valve) is used to control backflow from high-pressure formations through the drill string to the surface when joints are added. It also enables downward circulation of drilling fluid within the drill string.
Drift is used to pass through drill tubulars and accessories to verify internal diameter clearance and/or straightness.
Material: Made from UHMW (Ultra-High-Molecular-Weight polyethylene).
