Product introduction：NW-22 casing heads have s straight bore bowl design. NW-21 and NW-22 casing hanger can be used for NW-22 casing head. It can be with or without lockdown screw design. If a bowl protector were required during the drilling process, then we propose NW-22-BP casing head including lockdown screws in the upper flange. It can be used together with wear busing, test plug and some other tools to protect the sealing area and reduce the repairing cost. NW-22 casing head bottom connection can be threaded or slip-on for welding. NW-29 casing head structure is similar with NW-22, the only difference is the bowl is longer for casing NW-29 casing hanger, which can make the casing more straighter.
