Wellhead

The widely used wellhead comes with admirable flexibility, compatibility and interchangeability. Both S and SY shaft mouths consist of the lower casing head assembly, hanger as well as the subsequent casing head spool and the hanger.

S and SY Traditional Shaft Mouths
The traditional spool-type S and SY shaft mouths come with the strongest industrial capacity. Designed for all types of well completion and well depth, they adopt the duplex landing shoulders for obtaining the maximal supporting capacity of casing pipe. The maximum working pressure is 15000PSI (excluding the tubing head spool). The working temperature is from -20°F to +250°F (-29°C to +121°C).

Our wellhead products are provided for worldwide dealers, agents and terminal customers. We not only can provide the single component for dealers and agents, but also can satisfy the usage demands of terminal customers for the complete sets of shaft mouth device.
