The HDI 1000P Pressure Gauge System is a battery-powered, intrinsically safe electronic gauge used to monitor high-pressure systems in oil and gas operations. It measures pressure using a strain gauge sensor and provides real-time readings on a digital display with both numeric and bar graph formats. Common applications include choke manifolds, cementing units, coiled tubing, and high-pressure pumping systems.

With pressure ranges available from 5,000 psi up to 30,000 psi, the 1000P is suitable for demanding environments. It offers ±0.5% full-scale accuracy, and optional 4-20mA or 0–1 VDC outputs for integration with PLCs or remote monitoring systems. The unit is housed in a sealed stainless steel enclosure and built to perform reliably in harsh, high-vibration field conditions.

Designed for ease of use, the 1000P includes a field-replaceable battery pack and supports a range of connection types such as 2" 1502, 2002, 2202, or flanged. Its solid-state platform minimizes maintenance and ensures consistent performance over time, making it a dependable tool for critical pressure monitoring tasks.

The Bore Through Male Connector NPT fittings are engineered to create robust, leak-free connections in high-pressure systems. These fittings feature a bore-through design, allowing fluid or gas to flow freely without obstruction, which minimizes pressure drop and ensures consistent system performance. Made from high-quality materials, they are suitable for pressures up to 6000 PSI and are manufactured to meet ASME B16.34, MSS-SP-99, and ASME B31.3 standards.

The NPT (National Pipe Thread) male connection ensures a tight seal when connected to compatible threaded components, providing reliable performance in oil and gas, chemical, and process industries. The fittings are precision-machined for proper ferrule deformation, which ensures leak-free connections under vibration, impulse, or vacuum conditions. Silver-plated threads reduce friction and prevent galling, while the bore-through design supports high flow rates without obstruction.

Bore Through Male Connector NPT fittings are easy to install and maintain. They are finger-tight for initial assembly and then wrench-tightened to achieve a secure seal, reducing installation errors and downtime. Their design allows disconnection and reconnection without compromising sealing integrity, making them suitable for applications requiring frequent maintenance or system modifications.

These fittings are unique in combining full-flow capability, high-pressure performance, and reliable sealing in a compact, easy-to-install form, making them ideal for demanding oil and gas systems, process lines, and high-pressure instrumentation setups.

The HDI 1522 Choke Position Indicator System is an electronic instrument designed to accurately measure and display the position of choke valves used in oil and gas production. Choke valves regulate the flow of oil, gas, or water from wells by adjusting the degree of restriction in the pipeline, which directly affects pressure control and production rates. The 1522 system provides highly precise position readings in one percent increments, ranging from fully closed (0%) to fully open (100%), enabling better management of well performance and enhanced safety.

This system uses solid-state electronics to convert mechanical valve movement into electronic signals via various potentiometer types—including linear, rotary, and retractable options—making it adaptable to a wide variety of choke valve designs and configurations. The position data is presented on a four-inch liquid crystal display that combines a numeric readout with a linear bar graph, allowing clear and immediate visualization of the choke’s exact position. The display is engineered for visibility from distances up to fifteen feet, suitable for typical field environments.

Powered by an internal, field-replaceable battery with approximately one year of continuous operation, the 1522 system minimizes maintenance requirements and eliminates the need for complex wiring. It also offers optional analog output signals, such as 4-20 mA or 0-1 V, enabling seamless integration with plant control systems, programmable logic controllers, data acquisition systems, or remote display units for centralized monitoring and automation.

The enclosure is constructed from UV-stabilized, impact-resistant polycarbonate and PBT alloy materials to ensure durability in harsh outdoor conditions. It is rated to operate reliably within a wide temperature range from -40°F to 176°F (-40°C to 80°C). The internal electronics are protected by a gasket seal to prevent dust and moisture ingress, maintaining performance and longevity.

Installation flexibility is enhanced through support for cable lengths up to 1,500 feet, allowing the gauge to be mounted in the most accessible or secure locations. Multiple sensor housing options and connector orientations simplify field installation and reduce the need for onsite customization, helping to minimize downtime and installation costs.

The 1522 Choke Position Indicator System delivers accurate, real-time choke valve position information in a robust, easy-to-install package. Its reliable performance, flexible integration capabilities, and low maintenance design support improved flow control, safer operations, and optimized production.

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 H Type Flange to Flange is designed for use in the oil and gas industry to connect impulse lines and transmitters. Its simple two-valve configuration allows operators to perform essential tasks such as blocking, bleeding, and calibrating static pressure transmitters or gauges with ease. This design ensures accurate and reliable measurement while minimizing the risk of leaks or process interruptions.

The H Type manifold features a metal-to-metal body and bonnet seal, which provides a secure seal under high pressure and temperature conditions, eliminating the need for O-ring seals. The valves are designed with a self-centering, non-rotating tip to provide consistent positive shutoff and reduce wear on the packing. The stem includes a back seat for added safety, and a removable T-handle ensures smooth operation with low torque. A dust cap protects the stem from contamination, and rolled threads improve durability and ease of operation.

These manifolds are manufactured to meet ASME B16.34 standards for pressure-temperature ratings and are type tested to MSS-SP-99. They have a standard working pressure of 6000 PSI, with higher pressures available upon request. Materials can be supplied in accordance with NACE MR 01 75, and temperature ratings range from -50°C to 230°C, or up to 500°C with graphite. Every valve is factory tested for leakage and performance, and heat code traceability ensures quality and reliability.
