The 4 ½” x 2 3/8” tubing hanger coupling is a specialized downhole component designed to connect two different sizes of upset tubing within a wellhead assembly. Upset tubing refers to tubing that has thicker, reinforced sections at the ends—called “upsets”—which strengthen the threaded connections and help withstand the mechanical stresses and high pressures encountered during well operations. This coupling provides a secure and pressure-tight transition between a larger 4 ½-inch tubing hanger and a smaller 2 3/8-inch production tubing string, enabling effective management of wellbore fluids and maintaining pressure containment.

Engineered to integrate seamlessly with tubing hanger spools, wrap-around tubing hangers (PTHSW), and ‘PTHS’-type tubing spools, this coupling forms part of a modular wellhead completion system. Its union nut design allows installation by screwing the coupling in place without rotating the Christmas tree, simplifying assembly and reducing the risk of damage during installation.

Both the top and bottom ends of the coupling are threaded to customer specifications, offering flexibility for various well configurations and allowing the installation of back pressure valves to maintain well control during operations. Manufactured to API standards and constructed from high-grade materials, the coupling delivers durability and reliable performance in demanding downhole environments characterized by high pressure, temperature, and corrosive fluids.

By facilitating a smooth and strong size transition between different tubing strings, the 4 ½” x 2 3/8” tubing hanger coupling supports well integrity, operational efficiency, and safety throughout oil and gas production.

The 5 Valve Manifold T Type, Pipe to Flange is engineered to connect impulse lines to differential pressure transmitters in industrial and oil and gas applications. It features 1/2” Female NPT Pipe to Flange connections set at 54mm (2-1/8”) centers, with a configuration consisting of two block valves, two equalizer valves, and one bleed valve. This design allows for efficient isolation, calibration, and maintenance of transmitters while maintaining process integrity.

The T Type configuration is especially useful because it provides a compact and organized valve layout that simplifies operations like bleeding and equalizing, reducing the risk of leaks and measurement errors. Using a 5 valve manifold ensures maximum operational flexibility, allowing operators to isolate the instrument, balance pressure, and vent safely without interrupting the main process.

Pipe to Flange connections are chosen when connecting transmitters or instruments to existing flanged piping systems, offering strong mechanical support and compatibility with industry-standard flanges. This combination of T Type, 5 valves, and pipe-to-flange connections ensures accurate, reliable, and safe pressure measurement and calibration in critical oil and gas operations.

The 4 ½ x 2 7/8” Tubing Hanger Coupling is a specialized connection component used in oil and gas wellhead systems to join two different sizes of upset tubing—4 ½-inch and 2 7/8-inch. This size combination is commonly selected when there is a need to transition from a wider tubing hanger profile to a smaller production string, without significantly restricting flow or compromising mechanical strength. The slightly larger 2 7/8” production tubing allows for greater internal flow area than smaller alternatives, making this configuration well-suited for completions that aim to support moderate to high production rates.

The coupling is designed with a union nut mechanism, which enables installation without rotating the Christmas tree or disturbing other surface equipment. This simplifies operations, especially in space-limited or sensitive surface environments. Both the top and bottom threads of the coupling can be manufactured to meet specific customer requirements, ensuring compatibility with a range of tubing string designs. Additionally, the coupling is threaded to accommodate a back pressure valve, offering an important safety feature by allowing well pressure to be managed during maintenance or pressure control procedures.

Constructed from high-grade steel and compliant with API standards, the 4 ½ x 2 7/8” Tubing Hanger Coupling offers high durability, corrosion resistance, and the mechanical integrity required for challenging downhole conditions. By supporting a secure, pressure-tight connection between tubing sizes, it plays a key role in maintaining well integrity and operational efficiency in various oil and gas production scenarios.

Coiled tubing is a continuous, flexible steel pipe widely used in well intervention and maintenance operations, allowing operators to clean, stimulate, log, or deploy tools inside the wellbore without shutting down production. This capability makes coiled tubing an efficient and cost-effective solution to maintain well health and improve productivity.

The 3 1/16” 10M Coiled Tubing Hanger is designed to support larger diameter coiled tubing and heavier tool strings required for more demanding or deeper well operations. The size “3 1/16”” refers to the wellhead bore size that the hanger fits into, while the “10M” indicates its pressure rating of 10,000 psi, meaning it is built to withstand high-pressure environments typically found in advanced well interventions.

This hanger is rated to maintain pressure containment during interventions in high-pressure wells, ensuring safe operations and protecting well integrity. It accommodates coiled tubing sizes ranging from 1 inch up to 1¾ inches outer diameter, which allows the deployment of heavier and more complex downhole tools needed for challenging well conditions. Its rugged construction is engineered to withstand mechanical stresses from heavy tool strings and high pressures without compromising performance.

Designed with flanged connections compatible with API 6B and 6BX standards, the hanger integrates seamlessly with existing wellhead equipment, simplifying installation and maintenance. An important feature of this model is the wireline entry sub, which guides wireline tools into the tubing bore, facilitating additional intervention tasks. The wireline entry sub also provides a secondary annulus seal that prevents fluid or gas leaks and restricts any upward movement of the tubing, enhancing operational safety.

The hanger maintains a secure secondary annulus seal around the tubing, which is critical for isolating pressure zones and protecting against leaks during live well operations. This versatility makes the hanger suitable for various well intervention activities such as well cleanouts, acidizing, logging, and tool deployment, particularly in situations where larger tubing and higher pressures are involved.

The 3 1/16” size strikes a balance between tubing size and wellhead bore capacity. It is larger than smaller hanger sizes, allowing operators to use coiled tubing capable of handling more demanding operational requirements. Its high-pressure rating ensures safe operation in wells where pressures can reach or exceed 10,000 psi, common in deeper or complex reservoirs.

Available sizes: 2 3/8”, 2 7/8”, 3 1/2”, 4”, 4 1/2”, 5”, 5 1/2'” and 7”.

The 4-inch Surface-Controlled Subsurface Safety Valve (SCSSV) is designed for installation in wells with 4-inch production tubing and serves as a critical safety device to shut in the well during uncontrolled flow events caused by equipment failure or loss of surface hydraulic control pressure. The valve operates via a hydraulically actuated flapper mechanism that remains open under normal operating pressure but closes automatically if the hydraulic signal is lost. This fail-safe design isolates the wellbore, preventing unintended release of hydrocarbons and protecting both personnel and the environment.

The flapper mechanism is simple and robust, minimizing moving parts in the flow path and reducing potential points of failure. When open, the sealing surfaces are positioned out of the fluid flow path, which helps maintain smooth production flow and reduces wear on sealing components. The valve’s hydraulic actuation allows reliable operation under varying pressure and flow conditions commonly encountered in oil and gas wells.

The valve is wireline retrievable, which means it can be removed, serviced, or replaced using wireline tools without the need to pull the entire tubing string from the well. This capability significantly reduces well intervention time and associated costs while allowing maintenance or upgrades to be performed efficiently.

This SCSSV fits standard landing nipples with a seal bore of 3.313 inches and is rated for working pressures up to 5,000 psi. Its internal valve diameter is 1.75 inches, providing an appropriate balance between flow capacity and structural integrity for wells with moderate to high flow rates. The 4-inch tubing size is common in many oil and gas production wells, making this valve size versatile across different field conditions.

This size is commonly applied in production wells where 4-inch tubing is standard, supporting reliable well control and efficient maintenance. Its hydraulic surface control and simple flapper design contribute to dependable operation under varying well conditions.
