Casing Heads
WS-22 / WS-29 Casing Heads

WS-22 / WS-29 Casing Heads have a straight bore bowl with 45 degree landing shoulder design which avoids damage to sealing areas by drilling tools and prevents test plug and bowl protector wedging problems when pressure is applied.

 

WS-22 / WS-29 Casing Heads are normally furnished with treaded outlets; studded outlets are available upon request. Bottom preparations can be furnished treaded or slip-on-weld.

 

WS-29 Casing Heads are based on the same reliable design as the WS-22 with exception that the bowl is deeper, which permits the acceptance of the WS-29 Casing Hanger with larger load capacity for deeper drilling.
