Forging

     Forging services are offered on a wide range of tubular steels and sizes. Finishing and inspection equipment follow specifications as required for both API and premium upset requirements for tubes from 1.315" to 7.000" outside diameter. The following is a list of upsets and corresponding outside diameters available.

  • API EUE: 2.375" - 4.500" (standard and extended head)
  • PREMIUM INT. / EXT. UPSETS: 1.315" - 5.000" (CS, 533, 503, PH6, PH4, etc.)
  • DRILL PIPE: 2.375" - 5.500"
  • SPECIALITY UPSETTING: To your specifications

Heat Treating

     Our Heat Treating facilities offer full length normalizing or quench & tempering of tubing from 1.315" to 10.750" O.D. on a variety of furnace production lines. TSC can process tubing, drill pipe, mechanical tubing, casing, and bar stock. We are capable of processing tubing with lengths varying from API range 1 through range 3. All API and most proprietary grades are possible. Following heat-treating, the pipe is straightened on a cross-roll straightener or punch/gag press as required. The following is a list of available heat treatments and the corresponding available sizes.

  • Quench and Temper - 1.315" - 10"
  • Normalize, Temper, or Stress Relieve - 1.050" - 10.75"

Inspection

     NDT inspections, including magnetic particle, ultrasonic and EMI, are utilized to verify product integrity throughout processing in accordance with specification requirements. After heat treatment, the mechanical properties of the pipe are tested to insure they comply with API specifications.

Testing

     TSC's quality laboratories are equipped to perform tensile testing to verify mechanical properties, Rockwell hardness tester to verify hardness levels and uniformity, multi-power microscope to verify microstructure, and charpy tester to verify impact strength. A state-of-the-art chemical analyzer is used to verify conformance to API requirements.

Threading & Machining

     Our skilled machinists use state-of-the-art Computer Numerically Controlled (CNC) lathes for threading tubing and casing from 1.660" to 9.625" OD. All material is inspected by certified inspectors to ensure the highest quality. The following is a list of some of the services available:

  • API STC & LTC
  • API Round Threads
  • API Buttress
  • Specialty Buttress
  • Beveling
  • Facing
  • Custom Threading

Drill Pipe


     TSC manufactures a wide range of API and proprietary drill pipe products ranging from 2-7/8" to 6-5/8" OD in range 2 or range 3 lengths. Manufacturing begins with the highest quality raw materials from leading tube and tool joint manufacturers whose products are produced to TSC's demanding specifications. Our specifications exceed those of API and allow for exceptional quality of the finished product. As a result, we are able to guarantee 95% minimum wall thickness on all drill pipe we produce. The processing of tubes and tool joints, as well as the welding, is performed in-house to strict manufacturing specifications and quality control. TSC incorporates strict engineering controls in the weld line processes to ensure the consistent quality of every joint.

     We produce drill pipe to all API grades (E-75, X-95, G-105, S-135) as well as numerous proprietary grades, which among others, include NS-1 and IRP sour service grades. In addition, TSC's own proprietary grades are available for service requirements exceeding those of API. These grades include TSC-140, TSC-95CY, TSC-G105CY and TSC-105SS and offer either higher strength or improved corrosion resistance beyond API products.

     TSC drill pipe is offered with API's full range of connections or with proprietary high torque connections. Two double-shoulder high torque connections are offered; the TSDS series and the SSDS series. These connections exceed the capabilities of API connections and are easy and quick to run as well as economical.

     We offer the following services: hard banding - offered with a selection of hard metal products, make and break services and internal plastic coating according to customer preferences.

If you are interested in acquiring drill pipe contact our drill pipe division, TSC DRILL PIPE, directly.

API

     The American Petroleum Institute(API) issues the directives on which our Quality Program is designed. API establishes quality requirements for companies who wish to be a part of their program. An API product specification must be followed in order to put the API monogram on every conforming joint. The API monogram is a warranty to our customers that the pipe conforms to the API specifications to which it was processed.

Employees

     All of the specifications and procedures that everyone in the company works to are very formal and must be followed. All employees receive a special quality orientation to explain our extensive quality program. Each production worker receives Standard Operating Procedures from which they are trained to perform their job. After an on-the-job training period, each production worker receives a practical examination to ensure that the employee has been successfully trained and understands his or her responsibilities thoroughly.
