Expanding Plug Valve

The 04-SAMSS-041 specification outlines the minimum requirements for steel double block and bleed plug valves with retracting soft seals, commonly known as expanding plug valves. These valves are designed to provide reliable and efficient isolation for non-sour hydrocarbon services in a wide range of temperatures. The specification covers valves in nominal pipe sizes (NPS) 2 through 36 inches, suitable for ASME Classes 150 through 900 applications.

1. Purpose of 04-SAMSS-041 Specification:
   The primary purpose of the SAMSS-041 specification is to establish a set of standard requirements for steel double block and bleed plug valves used in the oil and gas industry. These valves play a critical role in providing positive isolation, minimizing the risk of leaks, and ensuring safe and efficient operations in hydrocarbon service applications.
2. Features of Steel Double Block and Bleed Plug Valves:
   The specified double block and bleed plug valves are equipped with retracting soft seals, which expand to ensure a reliable and bubble-tight seal during operation. The design includes two independent seating surfaces that effectively block the flow of fluid, providing enhanced safety and performance in isolation applications.
3. Suitable for Non-Sour Hydrocarbon Services:
   The 04-SAMSS-041 specification focuses on applications in non-sour hydrocarbon services, where the presence of hydrogen sulfide (H2S) is not a concern. These valves are designed to withstand operating temperatures ranging from -18°C to 120°C, making them suitable for various hydrocarbon processes and systems.
4. Range of Sizes and Pressure Classes:
   Valves covered by this specification are available in nominal pipe sizes ranging from 2 to 36 inches, catering to a wide range of pipeline and processing requirements. Additionally, they are designed to meet ASME Classes 150 through 900 pressure ratings, ensuring compatibility with various pressure and temperature conditions.
5. Non-Lubricated Plug Valves:
   One of the distinguishing features of the double block and bleed plug valves covered by 04-SAMSS-041 is their non-lubricated design. This eliminates the need for frequent maintenance and lubrication, reducing operational downtime and enhancing valve reliability.
6. Robust Construction for Harsh Environments:
   These expanding plug valves are constructed from high-quality steel materials, ensuring durability and corrosion resistance in harsh operating environments. The robust design makes them well-suited for onshore and offshore applications in the oil and gas industry.
7. Compliance and Quality Assurance:
   All valves manufactured in accordance with the SAMSS-041 specification must adhere to stringent quality control and testing procedures. Compliance with the requirements ensures that the valves meet the highest standards of performance, safety, and reliability.

Conclusion:
The SAMSS-041 specification sets a benchmark for the design and performance of steel double block and bleed plug valves used in non-sour hydrocarbon services. With their retracting soft seals, robust construction, and non-lubricated design, these expanding plug valves provide a dependable solution for positive isolation and safe operations in the oil and gas industry. Adherence to this specification ensures the consistent quality and performance of these critical valves, contributing to the efficiency and integrity of hydrocarbon processing systems.
