HDI Gauge systems used in oil and gas operations are often exposed to harsh environments and continuous use. To maintain accuracy, reduce downtime, and extend the service life of these systems, it is critical to have access to replacement components that are both durable and compatible. A full range of spare parts is available to support maintenance needs, including displays, sensors, cables, processor boards, connectors, and housing elements.

These parts are designed to be interchangeable across compatible models, allowing operators to replace worn or damaged components without requiring full system replacement. This modularity improves cost efficiency and simplifies logistics, especially in remote field locations. Most components are field-replaceable, reducing the need for specialized service technicians and enabling faster return to operation.

Processor boards and display units typically share a common design across multiple gauge models, streamlining inventory requirements and providing flexibility during urgent repairs. Sensors are matched with gauge heads for calibration accuracy but can be easily re-paired and recalibrated in the field or through service support if needed.

Using certified or manufacturer-specified replacement components ensures continued compliance with safety standards, maintains the expected measurement accuracy, and supports the longevity of the equipment. These parts are often backed by service documentation or part tracking for maintenance records and equipment history management.

In short, a well-organized supply of compatible, high-quality parts is essential for effective pressure and temperature gauge system upkeep in demanding industrial settings.

The 2 Valve Manifold T Type – Pipe to Flange 1/2” Female NPT is designed to provide a reliable and compact solution for connecting impulse lines to pressure transmitters and gauges. This manifold allows operators to safely isolate instruments from the process for maintenance, calibration, or testing, without the need to shut down the system. The T-type configuration features two valves that control flow to and from the instrument, enabling efficient block, bleed, and vent operations.

The pipe-to-pipe design ensures a direct connection to the piping system, which reduces potential leak points and simplifies installation. It is suitable for high-pressure applications, with a standard working pressure of 6000 PSI and options available for higher pressures. The manifold is built with a metal-to-metal body and bonnet seal for enhanced durability and temperature resistance, with materials that can comply with NACE MR 01 75 standards for corrosion resistance.

Additional features include a removable T-handle for low-torque operation, self-centering non-rotating stems for consistent shutoff, and a dust cap to prevent contamination. Packing is positioned below the stem threads to isolate the threads from the process media, and the stem’s rolled threads provide smooth operation and long life. The manifold is 100% factory tested for leakage and performance, ensuring reliable operation in critical oil and gas applications.

The HDI 2522 Choke Position Indicator System is a 4-inch solid-state electronic device used to precisely monitor the position of chokes in oil and gas operations. It provides position readings in 1% increments from fully closed (0%) to fully open (100%). The system supports a variety of choke types by interfacing with linear, rotary, or retractable potentiometers, making it adaptable to different choke designs commonly used in the industry.

This indicator eliminates the need for pneumatic air lines traditionally used for position sensing, improving reliability and reducing maintenance requirements. The gauge features a liquid crystal display (LCD) with both a numeric readout and an analog bar graph for quick visual interpretation of choke position. It includes a low battery indicator to ensure continuous operation.

The system is battery powered with a field-replaceable 3.6 Vdc power pack rated for one year of continuous operation. The internal battery powers the gauge electronics but not optional 4-20mA output loops. The 2522 supports up to two additional slave gauges for remote position displays, allowing flexible monitoring setups across control rooms.

Its robust, impact-modified polycarbonate/PBT alloy case is UV stabilized and sealed with gaskets to protect the electronics. The device operates within a temperature range of -40°F to 176°F (-40°C to 80°C) and is suitable for harsh oilfield environments.

Installation is straightforward, with recommended cable lengths up to 1,500 feet between the gauge and potentiometer, and customizable cable options available to fit specific site needs. Each system is factory matched and serialized, supplied with a signed calibration certificate, ensuring accuracy to within ±1% full scale.

Overall, the 2522 system provides a reliable, accurate, and low-maintenance solution for real-time choke position monitoring, enhancing operational control and safety in oil and gas production.

Hex Couplings Female NPT are pipe fittings designed to join two male threaded pipes in fluid and gas systems. The female NPT threads provide a tight seal when screwed onto male pipes, ensuring leak-resistant connections. The hexagonal shape allows easy tightening or removal using a wrench, making installation straightforward even in compact spaces.

These fittings are commonly used in oil and gas and process control applications. They are suitable for high-pressure systems, with pressure ratings up to 10000 PSI depending on the material. Hex couplings are available in stainless steel, brass, and carbon steel, offering durability and corrosion resistance in demanding environments.

Sizes available range from 1/8”, 1/4”, 3/8”, 1/2”, 3/4”, to 1”, providing flexibility for different piping setups. Their compact design and reliable performance make them ideal for instrumentation, process piping, and other applications where secure connections are essential.

Tube Fittings Male Connector NPT are used to connect tubing directly to threaded pipe systems, ensuring a secure and leak-tight joint in fluid and gas applications. The male NPT threads allow compatibility with standard pipe threads.

These fittings are unique due to their twin ferrule design, which provides a strong mechanical grip on the tubing while creating a reliable seal without requiring welding or additional sealants. The precision-machined ferrules deform evenly to prevent leaks, even under vibration, impulse, or high-pressure conditions.

Straight fittings are manufactured from bar stock, and shaped fittings are made from forgings, offering high structural strength. The case-hardened back ferrules and silver-plated female threads reduce wear and prevent galling, while the radius junction in elbows maintains smooth flow.

Installation is simplified: the tubing is inserted fully to the shoulder of the fitting, and the nut is tightened to specific torque, producing a secure connection. Male Connector NPT fittings are ready for immediate use and can be disassembled and retightened if needed.

Their combination of threaded pipe compatibility, twin ferrule sealing, and ease of installation makes them reliable and widely used in demanding industrial applications.

The Square Body Needle Valve Female x Female is engineered for precise flow control in high-pressure fluid systems commonly found in the oil and gas industry. Its design features a robust square-shaped body, which provides stability during installation and operation, reducing the risk of leaks and mechanical stress. The female x female configuration allows the valve to connect two female-threaded pipes or instrumentation components directly, eliminating the need for additional adapters and simplifying system layout.

The valve operates with a fine-threaded stem that provides smooth, accurate regulation of fluid flow, enabling controlled start, stop, and throttling functions. A metal-to-metal body bonnet seal ensures reliable sealing at high pressures and temperatures, while the back-seated stem and self-centering tip deliver consistent, leak-free shutoff.

These valves are suitable for a range of applications, including instrumentation, process monitoring, sampling, and control systems, where precise flow control and reliable operation are critical. The square body design also facilitates easy wrench access and torque application, making installation and maintenance straightforward in complex piping arrangements.
