04-SAMSS-050Gate Valves, Through Conduit Type, API SPEC 6D
The 04-SAMSS-050 Specification, in conjunction with the Purchase Order, outlines the minimum requirements for a specific type of gate valves used in the oil and gas industry. These gate valves are made of steel and have a soft-seated, full bore, slab gate, and through-conduit design. They are available in various sizes, starting from 2 inches, and are suitable for a wide range of pressure classes, from ASME 150 to 2500.
These gate valves play a crucial role in controlling the flow of liquid or gas in the hydrocarbon industry. They are designed to withstand the challenging conditions of wet, sour hydrocarbon services, which involve the presence of corrosive elements and varying temperatures.
The specified temperature range for these gate valves is between -18°C to 120°C. For even lower temperatures ranging from -45°C to -18°C, the 04-SAMSS-003 specification should be applied.
In addition to the general requirements, the specification also covers special services and features, which are detailed in the Appendices. These include metal-seated valves suitable for services with temperatures up to 205°C, where tight sealing is not required, as well as parallel expanding gate valves for services up to 120°C.
Overall, the 04-SAMSS-050 Specification is essential for ensuring the quality, performance, and safety of gate valves used in the oil and gas industry. It sets the standard for these critical components, which are vital for the efficient and reliable operation of hydrocarbon systems.
FAQs about Gate Valves, Through Conduit Type, API SPEC 6D
Answer: The 04-SAMSS-050 Specification covers the minimum requirements for steel, soft-seated, full bore, slab gate, through-conduit type gate valves in nominal pipe sizes (NPS) 2 inches and larger for ASME Classes 150 through 2500.
Answer: The specification addresses gate valves that have a soft-seated, full bore, slab gate, and through-conduit design. These gate valves are commonly used in the oil and gas industry.
Answer: The gate valves covered by this specification are suitable for wet, sour liquid or gaseous hydrocarbon services with temperatures ranging from -18°C to 120°C.
Answer: Yes, the specification includes Appendices that outline additional requirements for special services. Appendix A covers metal-seated valves for services up to 205°C where tight sealing is not required, while Appendix B addresses parallel expanding gate valves for services up to 120°C.
Answer: Yes, for low-temperature services ranging from -45°C to -18°C, the 04-SAMSS-003 specification should be applied instead of the 04-SAMSS-050. This ensures that the gate valves are suitable for the specific requirements of such extreme temperatures.
