The HDI 2021 Pressure Transmitter System is an electronic device designed to measure pressure accurately and convert it into a standardized 4–20 mA electrical signal for monitoring and control. It consists of a strain gauge sensor embedded in a stainless-steel housing and a transmitter assembly that processes the sensor signal. This system is widely used in oil and gas operations to provide precise, real-time pressure data essential for safe and efficient wellhead monitoring, pump and compressor control, manifold pressure tracking, and other critical process points.

In typical oilfield applications, the transmitter measures pressure at locations such as wellheads, flowlines, separators, and pumps to ensure that equipment operates within safe pressure limits, preventing failures and optimizing production. The 4–20 mA output enables easy integration with control systems, remote displays, data loggers, and automated safety shutdowns, supporting operational decisions and regulatory compliance.

The 2021 system supports pressure ranges from 5,000 psi to 20,000 psi, with overpressure protection allowing up to 30% above rated pressure for lower ranges, and 10% for higher ranges. It offers multiple housing options including hammer unions and various flanged connections to fit existing infrastructure. The sensor uses a high-quality strain gauge design with a robust stainless-steel case to ensure durability in harsh field conditions. A shielded instrument cable (up to 200 feet recommended) connects the sensor to the transmitter, minimizing electrical noise for reliable data transmission. The system is field repairable and designed with no moving parts or fluids, reducing maintenance needs and enhancing reliability.

The 2021 Pressure Transmitter System delivers accurate, dependable pressure measurement critical for monitoring and controlling high-pressure equipment in oil and gas operations, helping to maintain safety, protect assets, and improve production efficiency.

The Monoflange SBB Double Block and Bleed Valve with Flange x Thread connections features an OS&Y isolation valve and a needle drain, providing dual isolation in a single compact assembly. It is designed for oil and gas applications where safe venting of trapped pressure between isolation points is required, such as instrument or gauge isolation, chemical injection, and sampling lines.

The valve’s monoflange design integrates both isolation and venting functions in one unit, reducing the number of joints and potential leak paths while saving space and simplifying installation. The OS&Y isolation valve offers clear visual indication of open or closed status, allowing operators to quickly verify valve position. The needle drain provides controlled venting of pressure trapped between the isolation points, ensuring safe operation during maintenance or sampling procedures.

The valve is suitable for flange sizes from 1/2” to 2” and pressure classes from 150 to 2500, with options for reduced or full bore depending on process requirements. It is available in a variety of materials including stainless steel 316, 316L, duplex, super duplex, Hastelloy, Inconel, and Monel, and can be manufactured to meet NACE MR-0175 standards. The design complies with recognized standards such as ASME B16.34, API 6D, and ISO 17292, and is tested to low emission requirements.

This configuration is ideal for oil and gas operations requiring reliable dual isolation, precise venting, and compact installation in critical piping systems.

The 3 Valve Manifold T Type – Pipe to Flange is specifically engineered to connect impulse lines to differential pressure transmitters, ensuring accurate measurement and reliable operation in industrial systems. Its T-type configuration features two block valves, one equalizer valve, and vent/test ports, allowing operators to isolate the transmitter, equalize pressure, and perform maintenance or calibration safely without disrupting the overall process. This setup is particularly useful in oil and gas, petrochemical, and process control applications where continuous operation is critical.

The manifold is built with 1/2” Female NPT Pipe to Flange connections set on 54mm (2-1/8”) centers, providing standardized and secure interfacing with pressure transmitters. High-quality construction includes metal-to-metal body and bonnet seals to withstand pressures up to 6000 PSI and temperatures ranging from -50°C to 230°C, with higher temperature ratings available using graphite materials. The design ensures leak-free performance through features such as self-centering, non-rotating valve tips, back-seated stems for added security, and rolled threads for smooth operation.

Additional operational benefits include easily adjustable gland retainers for maximum packing stability, removable T-handles for low-torque operation, and dust caps to protect actuating threads. Each valve is 100% factory tested, with traceable heat codes, and meets rigorous standards including ASME B16.34, MSS-SP-99, and ASME B31.3, making the manifold a robust and reliable solution for high-pressure industrial applications.

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.
