The HDI 2200 Choke Position Indicator System is a battery-powered, intrinsically safe solid-state electronic gauge designed to monitor choke valve positions in oil and gas operations with high accuracy. It displays choke position in 1% increments from fully closed to fully open (0% to 100%) using a three-digit numeric readout alongside an analog bar graph segmented into 101 divisions for both precise measurement and quick visual trend analysis.

The system interfaces with linear, rotary, or retractable potentiometers housed in stainless steel enclosures. This flexibility allows for straightforward adaptation across many choke configurations without the need for onsite customization. The sealed stainless steel housing and solid-state electronics enable the 2200 to operate reliably in harsh field conditions, including high vibration environments typical in land and offshore drilling.

Its compact display unit measures approximately 8 by 8 by 4 inches and weighs around 5 pounds. The system is powered by an intrinsically safe 3.6V DC battery pack, with a low battery indicator to ensure timely maintenance and uninterrupted operation. Field-repairable components minimize downtime and allow for easy servicing. The system supports dual sensors for integration with human-machine interfaces (HMI) or programmable logic controllers (PLC), enabling remote monitoring and automation. The 2200 system replaces traditional pneumatic indicators, eliminating the need for air lines and reducing maintenance complexity, while offering a simple calibration interface to facilitate setup and ongoing adjustments.

Hex Reducing Nipples Male NPT are pipe fittings designed to connect two female-threaded pipes of different diameters while maintaining a secure and leak-resistant seal. The male tapered threads provide a tight connection that prevents fluid leakage, which is especially important in high-pressure systems.

These fittings are widely used in the oil and gas industry, chemical processing, and instrumentation applications where a reduction in pipe size is required without adding extra joints.

They are manufactured from high-quality materials such as stainless steel, brass, and other compatible alloys, ensuring durability and resistance to corrosion. The fittings are precision-machined from bar stock to provide burr-free internal surfaces for smooth flow and to reduce turbulence within the system. Threads are carefully capped and packed to prevent damage during transit.

Hex Reducing Nipples are rated for pressures up to 10,000 PSI and comply with ASME B1.20.1, SAE AS71051, ISO 7-1, and ISO 228 standards. They are designed for reliable performance in ambient temperatures from -28 to 37°C (-20 to 100°F) and support efficient installation with standard wrenches thanks to the hex shape, which allows secure tightening. These features make them suitable for high-pressure and instrumentation piping systems where both reliability and traceability are required.

The Gauge Root Valve Female x Female connection is designed to control and isolate pressure instruments in process systems, particularly in oil and gas applications. It is rated for a standard working pressure of 6000 PSI, with the option for higher pressures upon request.

The valve is type-tested to MSS-SP-99 and designed according to ASME B16.34 for pressure-temperature ratings, ensuring reliable performance under demanding conditions.

The valve features a metal-to-metal body and bonnet seal, providing high-pressure and temperature sealing without the need for O-rings. It can operate in temperatures from -50°C to 230°C, with graphite sealing available for applications up to 500°C. The stem has a backseat for added security, and a self-centering, non-rotating tip ensures consistent shutoff and leak-free performance.

The packing is located below the stem threads, isolating the threads from process media, and the gland retainer is easily adjustable for maximum packing stability. The valve includes a removable T-handle for low-torque operation and a dust cap to prevent contamination. All valves are factory-tested with nitrogen at 1000 PSI to verify seat and packing leakage, with a maximum allowable leak rate of 0.1 sec/min.

Materials can be supplied to meet NACE MR 01-75 standards, and heat code traceability is provided. Additional tests, including vibration, temperature, and helium, are available on request. This design ensures long-lasting, reliable operation while protecting connected instruments and maintaining safety in high-pressure systems.

Gauge adapters with a female ISO parallel thread to male NPT are small but essential components used to connect measurement instruments, such as pressure gauges or transmitters, to piping systems in industrial and oil and gas applications.

The female ISO thread screws directly onto the instrument, while the male NPT thread connects securely to the pipe or tube, creating a tight and leak-resistant connection.

These adapters are made from high-quality materials such as stainless steel or brass, which makes them durable and resistant to corrosion, even in harsh environments. They are designed to handle high pressures, up to 10,000 PSI, ensuring that instruments provide accurate readings without risk of failure.

They follow international thread standards including ASME B1.20.1, SAE AS71051, ISO 7-1, and ISO 228, which guarantees compatibility with other equipment and ensures reliable performance in critical systems. This makes them a practical and dependable choice for monitoring and controlling fluids.
