Casing Hanger
PARVEEN Casing Hangers are basically 2 types i.e. Automatic Casing Hanger(PCHA) and Unitised Casing Hanger(PCHU). Automatic Casing Hanger(PCHA) is basically designed for heavy load service and is used for PARVEEN's Casing Head Housing 'PCHH' and Casing Head Spool 'PCHS' described earlier. When the Casing load is applied to the hanger, the top ring connected by the pack-off and shoulder screw compresses the packing to seal the annulus pressure of the casing. This casing hanger is normally used for pressure ratings upto 3000 PSI, type 'PSPO' Pack-off is used to prevent collapse of the pipe.

Unitised Casing Hanger (PCHU) can be used both for PARVEEN's Casing Head Housing(PCHH) and Casing Head Spool(PCHS) as described earlier. This Hanger is designed for medium or heavy load service. This hanger is normally latched around the pipe and lowered in casing head body. After the casing is landed, shoulder screws should be evently tightened to effect a positive annular seal. The hanger may be used upto 3000 PSI WP. For ratings over 3000 PSI, 'PSPO' Pack-off is used to prevent collapse of the pipe.

Tubing Hanger
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 continuos 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 pressure by compressing the seal with the weight of 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 wraped 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 pressure. This tubing hanger is used together with a tubing hanger coupling and a tubing hanger spool.

Dual Split Type 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'.

Extended Neck Type Tubing Hanger
Extended Neck Type Tubing hangers are equipped with a control line (or lines) to control the opening and closing of sub-surface safety valves (SSSV) from the 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. These hangers can also be offered with premium threads at request.

Parveen's Mandrel Type Tubing Hanger with metal to metal seals called 'PTHTSM' are used with Parveen's Tubing Spool and are equipped with metal to metal seal for fluids which prohibit the use of elastomer seals. These hangers have metal rings at the top and bottom for sealing. The rated working pressure range is 5000 psi to 15000 psi.

Parveen's PTHTSMM hangers fitted with single or dual hydraulic control lines are called PTHTSMM1 & PTHTSMM2. These are equipped with metal to metal seals for fluids prohibiting the use of elastomeric seals. Sealing is affected by metal ring mounted on the top of the hanger and load applied to the bottom of the hanger body.
