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.

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.

Reducing adapters Female to Male NPT are used to connect pipes or instrumentation lines of different diameters in oil and gas systems. They allow a larger pipe or fitting to join with a smaller one without leaking, ensuring the flow of liquids or gases remains safe and controlled. These fittings are especially useful in situations where space is limited or existing piping needs to be adapted to new equipment.

They are made from high-quality materials such as stainless steel, brass, or carbon steel, which can handle pressures up to 10,000 PSI. The female NPT side threads internally to receive a male pipe, while the male NPT side threads externally to connect to a female fitting. This combination provides a secure, leak-resistant connection that is durable even under high pressure, vibration, or temperature changes.

Reducing adapters are widely used in oil and gas production, processing, and distribution systems.

They are ideal for connecting instrumentation, control systems, chemical injection lines, or any piping where size changes are required. Their compact design and simple installation make them a practical choice for engineers and technicians who need reliable connections in complex piping networks.

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.
