Downhole Tubing For Thermal Wells

Centron tubing is precision wound on state-of-the-art computer controlled equipment. The advanced filament wound construction provides the high axial modulus and tensile strength required for downhole applications.

Centron Downhole Tubing is available in two threaded connection systems:

1. Centron's proprietary 4 round thread connection features the multiple seal capability and reliability of both thread and O-ring seals along with outstanding tensile strength across-the joint. The connection system prevents thread lubricant/sealant from entering the formation in injection service minimizing formation damage.
2. The Petroleum Industry API 8RD EUE long thread per API specification 5B, Table 14 (2 thru 4 inch) and Table 7 (6 thru 10 inch) (tolerances per API Specification 15HR). Both thread forms are available in Centron's patented (PeNG Premium Non-Galling) Female Carbon Thread for ease of make-up and breakout required in downhole applications. Diameter range: 1 ½ inch (40 mm) – 4 ½ inch (115 mm). Pressure range: up to 2500 psi (170 bar).
