NW-A and NW-B Connectors
Printable Version

Shutting in a production platform during installation of welded casing and diverter heads is costly, yet necessary for the safety of personnel and the environment. The only safe way to continue platform activities uninterrupted is to use an alternative connection method which requires no open flame. The NW series of diverter and casing heads provides a simple, safe and reliable solution to this problem.

Casing Heads The NW-A casing head consists of a standard S-22 bowl with a manually locked slip mechanism. The seal between the conductor and the wellhead is achieved with injectable elastomers.
Diverter Heads The NW-B diverter head consists of a full-open bore and friction pin locking mechanism which makes the head easily removable. The low pressure seal is formed by injectable elastomers.
