CASING & TUBING HANGER

Tubing Hangers - PARVEEN's Tubing Hangers are

basically four types. These are Mandrel Type 'PTHSM',
Wrap Around Type 'PTHSW', Extended Neck Type 'PTHSE'
and Dual Split Type 'PTHDE'. Extended Neck Type with
control lines 'PTHSCL', Dual Split Type with control lines
'PTHDCL', mandrel type with metal to metal seals
(PTHTSM) and Mandrel type equipped with a continuous
control line with metal to metal seals such as PTHTSMM are
also supplied.

'PTHSM' type Tubing Hanger is used for the PTHS type of

Tubing Head Spool described later. It seals the annulus
Type PTHSE pressure by compressing the seal with the weight of the
Extended Neck Hanger
tubing and the hold down screws.

Extended Neck Type 'PTHSE' is used for the Tubing

Head/Spool described later. This type is like 'PTHSM' type
tubing hanger but having an extended neck with a seal ring
which seals fluid in the tubing. This type seals the annulus
pressure by compressing the seal with the weight of the
tubing and the hold down screws.

The 'PTHSW' type is a split type tubing hanger and may be

wrapped round the tubing. It seals the annulus pressure by
compressing the seal with the hold down screws installed in
the top flanges of the spool. This type of hanger is used
where tubing must be rotated or moved up and down under
Type PTHSW pressure. This tubing hanger is used together with a tubing
Wrap Around Hanger
hanger coupling and a tubing hanger spool.

CASING & TUBING HANGER

Dual split type Tubing Hanger 'PTHDE' is used for

Dual Tubing String applications. This utilises plastic
packing between the seals for sealing. It is fixed by hold
down screws.

Dual split type tubing hangers can also be fitted with

hydraulic control lines 1 or 2 called 'PTHDCL1' &
'PTHDCL2'.

surface. These are called 'PTHSCL1' & 'PTHSCL2'.

The type 'PTHSCL1' is equipped with 1 (1/4") hydraulic

control line while 'PTHSCL2' is equipped with 2
hydraulic control lines. Both these types seal the
annulus pressure by compressing the seal with the hold
down screws installed in the type 'PTHS' Tubing spool
top flange.
