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.

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

The 3-1/2" WR-SCSSSV FXE is a Ballycatter model safety valve specifically designed for installation in the upper wellbore to provide an emergency shut-off of the production flow path. This valve plays a crucial role in well control by isolating the wellbore during emergency situations such as system failures or damage to surface production control facilities. Its fail-safe design ensures that the valve automatically closes to protect the wellbore and surface equipment whenever a fault occurs.

This safety valve is a flapper-type valve that is both surface controlled and wireline retrievable, allowing operators to easily deploy, operate, and retrieve the valve without extensive well intervention. The valve is installed within a corresponding model Landing Nipple, ensuring precise fit and reliable operation within the tubing string.

The design incorporates a self-equalizing mechanism that balances pressure differentials across the valve, which helps maintain consistent performance even under varying downhole pressures. This self-equalizing feature reduces the risk of valve malfunction due to unexpected pressure changes.

When the valve is in the open position, the sealing surfaces are positioned outside the flow path, ensuring that the fluid can pass freely without obstruction or erosion on the sealing components. This arrangement optimizes flow efficiency and helps extend the valve’s operational life. The flapper itself is made from solid bar stock, providing a strong and durable barrier that can withstand the harsh conditions found in high-pressure well environments.

The valve is rated for working pressures up to 10,000 psi, allowing it to operate reliably under high-pressure well conditions. The 3-1/2" WR-SCSSSV FXE is designed to ensure wellbore isolation in emergency situations, providing a critical safety function in the well control system.

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

The 2 7/8" Surface-Controlled Subsurface Safety Valve (SCSSSV) is designed to shut in a well to prevent uncontrolled flow caused by equipment failure or damage. It is installed in the upper wellbore to provide emergency closure of the production tubing, isolating the wellbore if there is a failure in the surface production control system or downhole equipment.

The valve operates on a fail-safe principle, closing automatically when control pressure is lost. It features a flapper-type mechanism and is surface-controlled through hydraulic pressure. The design is self-equalizing, which helps maintain pressure balance across the valve during shut-in and restart, ensuring consistent performance.

This valve is wireline retrievable, meaning it can be removed or serviced without pulling the entire tubing string, reducing well intervention time. It is compatible with landing nipples having seal bore diameters of 2.125", 2.188", or 2.313", allowing flexibility in well design.

The valve is rated for working pressures up to 5,000 psi and offers internal flow passage options of 0.81" or 1.12". The sealing surfaces are located outside the flow path when the valve is open, minimizing erosion and wear. The flapper is made from solid bar stock to provide mechanical strength and durability.

This configuration is commonly applied in wells where emergency shut-in is necessary and regular maintenance without tubing retrieval is preferred.

The 2 1/16” 5M Coiled Tubing Hanger is designed to support coiled tubing strings in well intervention and completion work. With a 5,000 psi pressure rating, it’s well-suited for moderate to high-pressure wells, and its compact 2 1/16” size makes it ideal for smaller wellheads or space-constrained setups.

It handles tubing sizes up to 3 1/2” O.D. and is commonly used for cleanouts, stimulation, logging, and other coiled tubing operations. A built-in wireline entry sub helps guide tools into the tubing while providing an extra seal and preventing tubing movement—improving well control and operational safety.

The hanger is available with API 6B or 6BX flange connections and can include a side outlet if needed. It’s a reliable, field-proven choice for operations requiring strong support and safe access to coiled tubing tools.

The 4” Tubing End Locator is designed specifically for use with larger production tubing strings common in wells that require greater flow capacity or enhanced mechanical strength. This size is typically found in wells with higher production rates or more demanding operational requirements, where accurate depth confirmation becomes even more critical.

This model is specifically sized for 4-inch outer diameter tubing, featuring a maximum outside diameter that fits comfortably within the tubing’s internal dimensions. This sizing ensures that the locator can move smoothly without obstruction while maintaining effective contact to detect the tubing end. The core mechanism involves a spring-loaded finger that extends outward upon contacting the tubing bottom. This movement translates into a tactile signal felt at the surface, eliminating the need for complex electronic systems and reducing the risk of failure in harsh downhole environments.

Equipped with standardized threaded connections—commonly a 1-9/16 - 10 UN pin on the top and a 1 - 11 ½ NPT box on the bottom—the tool integrates easily into typical slickline, wireline, or coiled tubing toolstrings. The fully mechanical design enhances reliability, making it well-suited for use in conditions of high pressure, elevated temperatures, and corrosive fluids often found in oil and gas wells.

The 4” Tubing End Locator is especially valuable in wells with larger tubing sizes where accurate depth confirmation is critical to avoid operational errors. By providing a straightforward and dependable method to locate the tubing end, it supports safe and efficient well intervention, helping to reduce downtime and operational risks.
