Tubing hanger is an assembly to support tubing string and seal the annular space between tubing and casing,which is connected with tubing and seated into fubing hanger spool by tubing gravity t is convenient to operate and replace wellhead so that it is widely used for intemediate depth well and common well.

Tubing head is usually a spool with both flanged ends,which is set on the top flange of casing head to hang tubing hanger and seal the annular space between the tubing string and oi-layer casing and which consists of tubing head spool and tubing hanger.
