01 The tubing spool is an apparatus fastened to the highest or smallest casing string. It is applied to seal the gap between the tube and casing. Metals like high manganese steel, carbon steel, and stainless steel are used to make a variety of tubing spools. The spool connects with a tubing adapter atop an oil well and supports the tubing string. It has an upper and lower flange for holding the pack off the tubing hanger and testing the secondary seal. It has several components: an upper bowl, a locking screw, a load shoulder, a secondary seal region, a test port, an outlet, lower and upper flanges, and a ring gasket groove.
