TC and TCM Tubing Heads are a straight bore bowl with 45° landing shoulder design which avoids damage to sealing areas by drilling tools, and prevents wedging of the tubing hangers, bowl protectors and test plugs. the secondary seal for the last casing pipe can be an integrated “OO” seal type or the plastic injection type, but also accepts reducer bushings “4-O” and “PE” (Pressure Energized).
The upper flange is supplied with lockdown screws for pack off re-nergization and tubing hanger retention. The lower flange includes a grease fitting and orifice for testing of the secondary seal. TCM Tubing Head can use for single completions and model TC for dual completions
