WELLHEAD EQUIPMENT

Tubing Head Adapters

A tubing head adapter provides the pressure-containing transition between the tubing-head spool and the Christmas tree while sealing around the selected tubing-hanger neck and accommodating completion penetrations where required. Single- and multiple-string configurations can include downhole-control-valve ports, chemical-injection ports, fibre-optic instrument ports and ESP penetrator profiles when specified.
