Wellhead Adapter Flange
The Elmar Wellhead Adapter Flange provides a means of connecting the wireline valve and lubricator assembly to the wellhead
in a safe and secure manner.
The Elmar Wellhead Adapter Flange consists of a quick union
machined on a standard API flange. The upper end has a standard Bowen
type, Otis type or Elmar quick union and can be supplied with a blanking
plug and collar if required.
Elmar Wellhead Adapter Flanges are available in various bore sizes and working
pressures up to 15,000 psi.
Elmar will design and manufacture well-head adapter flanges for all API and Russian
“GOST 28919” standard models. Elmar Adapter Flanges are fully traceable and
certified to API 6A.
