API Pressure control Equipment


Adapter & Spacer spools

From 2 000 psi - 20 000 psi rated working pressures GulfTek Arabia manufacture Adapter and spacer spools wellhead sections that have no provision for suspension of tubular members, and that can have no provision for sealing of tubular members. Spacer spools have end connectors of the same size, rated working pressure and design. Adapter spools have end connectors of different sizes, pressure ratings and/or designs.

Double studded adapter

Double Studded Adapter flange is the part which is often used in the wellhead system, DSA is designed and manufactured in accordance with API 6A standard, DSA usually has double studded flange connections. we have all sizes and pressure ratings DSA used for oilfield applications.

Crossover connector

A Crossover is a one-piece threaded tubular subassembly that is used to connect two different or same thread type components. It is also used to connect two tubular sections such as casings, tubing or drill pipes together. Crossovers are widely used during completion activities to connect two same or different types or size of components which otherwise cannot be screwed together because of difference in their thread size or type.

Top connector

Top Connectors specified in API Spec 6A have designated uppermost Collar connections for specific Flange and Hub sizes and working pressures. API Spec 6A does not mention cross adaptation. Following the exact Flange / Hub top connection specification allows operators to always know the uppermost connection if they know the Run connections of the Christmas Tree. If adapting proves necessary operators may use an independent unit of equipment or order a special Top Connector with the desired combination of sizes and pressures.

Tee & Crosses

Standard terminology for the connections and configurations of Crosses, Tees and Elbows:
GulfTek Arabia manufactures Studded Crosses, Tees and Elbows according to the designs and tables specified in API Spec 6A. When specific nominal sizes and combinations of nominal sizes do not appear in API Spec 6A, GulfTek Arabia. shall manufacture Studded Crosses, Tees and Elbows according to the design criteria provided in API Spec 6A.

Swivel flange

A flange consisting of two parts, a hub and a ring. The hub contains the gasket profile, and the ring features the bolt-hole pattern. The ring can rotate around the hub for easier makeup. Once the bolts are tightened, the ring is compressed against the hub via a shoulder and secured in place.

Weld neck connectors

Weld Neck Flanges are flanges that designed to be joined to a piping system by butt welding. the WN Flange is preferred for high stress applications. The neck, or hub, transmits stresses to the pipe, reducing stress concentrations at the base of the Welding-Neck flanges. The gradual transition of thickness from the base of the hub to the wall thickness at the butt weld provides important reinforcement of the Weld Neck flange. The bore of the Weld-Neck flange matches the bore of the pipe, reducing turbulence and erosion.

Bull plug

A solid plug used as an isolation device in piping systems, conduits, or wellbore tubulars

Flanged / Grayloc type Hub connections

A flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed. The Grayloc connector provides a highly reliable metal-to-metal seal that is both self- energized and pressure-energized. A complete Grayloc type connector consists of two hubs, one seal ring, one set of clamps, stud bolts, and spherical-faced nuts. Assembly and maintenance simplified.

Shooting nipple

used for quick access to the wellbore.

Gate valve

A multi-turn valve that has a gate-like disc and two seats to close the valve. The gate moves linearly, perpendicular to the direction of flow. This type of valve is normally used in the fully opened or fully closed position; it is not suited to throttling applications. Gate valves provide robust sealing and are used extensively in the petrochemicals industries.

Surface safety valve

The Well Test Surface Safety Valve (SSV) is a hydraulically actuated, fail-safe gate valve installed upstream of the choke manifold. A range of SSV gate valves are available at working temperatures of -20 to 450°F (-29 to 232°C) and are DNV-type approved in accordance with API 6A, Annex F, PR2.

Hydraullic Actuated Gate Valve

Hydraulic actuated valves are used for the automatic closing of gate valves on wellheads and flow lines under emergency conditions. The system consists of a hydraulic actuator and a reverse-acting gate valve.

Manual Choke

Choke Valves provide flow restriction in high pressure applications such as choke manifolds, flow through manifolds and test manifolds. Various forged-body configurations are available in 2-inch and 3-inch sizes, each rated at 15,000 psi NSCWP. Chokes are also available in sour gas configurations rated at 10,000 psi NSCWP. Chokes are designed for field applications such as drilling mud lines, including choke and kill lines and well service lines for cementing, fracturing, acidizing, and testing.
