Typical components of a frac manifold include spools, tees, crosses, gate valves, and goat heads. These are assembled into various configurations to suit the number and spacing of wells being simultaneously serviced, the planned arrangement of the frac lines, the extent to which actuation is desired, etc. Parveen’s frac manifolds may also be equipped with a safety ladder and platform to provide safe access to the valves.

Parveen tree is built to reduce bending stress at the tree connection and can be operated with pneumatic, hydraulic, or electric actuation.
The horizontal tree represents a more than 50% reduction in size and about 25% in weight from our first conventional frac tree. It is short, stable, and easily anchored – an ideal configuration for frac-tree service. The 90° goat head is located at the end of the horizontal section, resulting in the distance across which the bending loads act being less than half of that of a conventional stacked-valve frac tree.

These are the equipment often used on frac tree and frac stacks during fracturing work, which is often in studded and flange-end connections. The Frac Head reduces the risks normally associated with using substandard equipment.

For sour gas services and to withstand the damaging effects due to both Hydrogen Sulfide (H2S) and Carbon Dioxide (CO2) gases are provided to assemble with stainless steel ring gaskets. In addition; the PARVEEN Frac Head is machined from solid raw material and hardened alloy steel, making it more durable and safer for high-pressure service.

The Hydraulic Choke is a hydraulically operated variable choke providing any opening from a maximum of 1.93 square inches (1 9/16” equivalent bean diameter) to full shut off. The working pressure rating of the choke is 10,000 PSI. Two Tungsten Carbide discs, each with a semi-circular opening, form the choke. Various openings are obtained by rotating the upstream disc against the stationary downstream disc.

These are used in many oilfield applications to control the rate of flow. Usually, an adjustable choke is used as part of a manifold installed downstream of the wellhead. The choke is adjusted during the flow back of the well to control downstream pressure and flow rates. The PARVEEN adjustable choke is comprised of three main sub-assemblies. These sub-assemblies are the bonnet, tee, and nipple assemblies.

PARVEEN chokes are available in 3/4”, 1”, and 2” maximum orifice sizes with Fig. 602-1502 hammer union connection.

Positive Chokes accommodate fixed orifice dimensions. All PARVEEN Adjustable Chokes can be converted into Positive Chokes by replacing the bonnet assembly with an appropriate blanking plug assembly and choke bean. These are manufactured up to 7″, 15,000 PSI with all types of end connections.

PARVEEN External Sleeve Control Chokes minimize erosion and improve flow characteristics suitably for erosive service and under the high-pressure drop, with sand concentration. It applies the principle of “Flow Impingement” to dissipate and contain the destructive forces of cavitation, within the heavy-duty thick-walled cage of Tungsten Carbide.

Pneumatic Diaphragm Gate Valve has less friction, close-open quickly, long life, and dependable sealing. It could be an SSV (Surface Safety Valve) with an Induction System, driven by compressed air. When the fluid pressure in the pipeline has some troubles, it will be auto-off, and it could auto-off the main valve while controlling system pressure blabbed. This valve has been installed with the manual pressure relief device, overpressure auto protector, and manually operated device.

PARVEEN type actuator is a fail close hydraulic actuator. The actuator is operated by hydraulic pressure applied through a static piston on a translating cylinder. The cylinder actuated by hydraulic pressure compresses the spring by an upper spring retainer plate and directs the bonnet stem and gate into the open position. Should the hydraulic pressure within the cylinder/piston be vented, the spring arrangement ensures an instantaneous valve closure regardless of line pressure.

A spring arrangement, piston & hydraulic cylinder are assembled in a single package enclosed in housing by dual spring plates positioned within a flange and a location shoulder. The actuator assembly is easily removable from the valve for maintenance, actuator replacement, or transportation. Hexagonal screws on the lower plate & a threaded The connection between the traveling cylinder & stem keeps the actuator connected to the valve.

The PARVEEN High-Temperature Gate Valve uses a parallel expanding gate to obtain a perfect shut-off. The sealing is metal – to metal, both on the up and downstream of the valve, and unaffected by vibration and heat. The valve is the standard Model ‘E’ gate valve, modified with an extended bonnet and stem to place the stem packing outside the critical heat zone.

It has been tested in accordance with API requirements for use on the surface wellhead to casing systems, where the seal can readily replace the metal end cap and plastic pack sealing arrangement.

Type ‘P’ Seals (Secondary Seals) is an elastomer seal comprised of an injectable, formed seal ring flanked by two anti-extrusion rings. A single seal is recommended for pressures up to 5,000 psi. Used in a double seal configuration, and depending on the size of the seal, the Double P seal can be rated up to 15,000 psi. This easy-to-install, reliable, and field-proven design is one of PARVEEN’s standard, integral, elastomer seals offered with conventional equipment.

The tubing head adapter provides a transition between the Christmas tree and the tubing head. The bottom adapter connection matches the tubing head and the top adapter connection matches the tree. Tubing head adapters are available for all types of single- and multiple-string completions, including those using electric submersible pumps, packers, downhole control valves, and gas lift valves. These adapters come with threaded, flanged, or studded-flanged top connections. Most tubing head adapters are available with hydraulic supply inlets for downhole control lines. If the customer requires, PARVEEN also supplies various types of adapters that will accommodate continuous control-line capabilities.

It Provides sealing bore for a variety of electrical feed-thru configurations, including penetrators, cable pickoffs, and continuous feed-thru penetrator mandrels. Also, it has reliable seal bores for tubing hanger neck or seal sleeves.

Tubing hangers are installed in the top bowl of a tubing head. Tubing hangers both suspend tubing and provide a primary annulus seal between the tubing and production casing. Hangers are run through the blowout preventers and are landed in the top bowl of the tubing head. Tubing hangers also act as a means to access and manipulate additional smaller tubing lines that are utilized downhole and extended to the surface on the outside of the tubing string or strings.

PARVEEN Surface Wellhead type TC-Series tubing hangers are available for any type of single- or multiple-string tubing completion, including those requiring packers, subsurface safety valves, gas lift valves, and electric submersible pumps. All PARVEEN Surface Wellhead hangers can be run through the blowout preventers, allowing the well to be secured before the preventers are removed. Most type TC-Series tubing hangers accept a back-pressure valve, which seals the tubing bore. Some hangers are ported for hydraulic control lines, downhole safety valves, or other equipment as required by the customer.

The tubing head is the top spool on a surface wellhead assembly. It is installed after the last casing string to provide a load shoulder to support the tubing string and a seal bore for the tubing hanger or production casing/tubing annulus seal. When the well is completed, the tree is installed on top of the tubing head with a tubing head adapter.

“Wedge locking” of bowl protector, BOP test plugs, and tubing hangers is eliminated, Seal bore is less likely to be damaged during drilling, It’s more economical to recondition after abandon.

Double Studded Pack off Flange, provides a double” P” or “FS” seal for sealing the casing. The double studded pickoff flange is also used as an intermediate crossover flange when a restricted area is used in the smaller diameter top groove. When a crossover is used, the top connection can be exposed to a higher pressure than the original rated working pressure. The double molded elastomer P seals are energized by injecting the high-pressure grease/plastic packing.

Slip-type casing hangers provide a method to transfer the weight or tension load of a casing string to a casing head or casing spool. Slip-type hangers are available in automatic-sealing and nonautomatic-sealing varieties. Automatic hangers have seals that are energized by casing weight, while nonautomatic hangers have seals that require means other than casing weight to be energized. Nonautomatic hangers are typically used when insufficient casing load is available or when cementing back to the surface.

It Provides easy wraparound or split installation at any location on the casing string, Also provides suspension of the casing load from a casing head or spool, It gives the means to center the casing string in the head or spool.

The casing spool has a top bowl to accommodate the casing hanger. The spool also has a bottom bowl with a pack-off seal and a flange or clamp hub for mounting it on top of a casing head or previous spool. Outlets are provided for annular access. Multiple casing spools may be stacked to hang intermediate and production casing strings.

Straight bowl prevents wedge-locking of bowl protectors, casing hangers, and test plugs. Also, Type C-22-EG reduces the number of leak paths, lowers cost, and increases safety

The casing head is the lowest part of the wellhead assembly and is connected to the surface casing string. It supports subsequent drilling wellhead and completion equipment.

Casing Heads provides for attachment to the surface casing string, Supports blowout preventers while the hole is drilled for the next casing string. Also, provides for suspending and packing off the next casing string and outlets for annular access. It’s useful for testing BOP’s while drilling.
