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).
