As a professional manufacturer with a solid foundation since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in delivering high-performance fluid control solutions for demanding industrial applications. Our CB/T3191 Standard Ball Valve for FPSO Piping is engineered specifically to meet the rigorous requirements of Floating Production Storage and Offloading (FPSO) vessel piping systems. Constructed from robust low-temperature carbon steel, this valve series from DN15 to DN80 offers exceptional reliability, durability, and sealing performance in challenging offshore and subsea environments, ensuring safe and efficient operation of your critical processes.
Designed to comply with the Chinese CB/T3191 standard, which outlines the technical requirements for marine valves, our ball valves are tailored for the unique pressures, temperatures, and corrosive conditions encountered in FPSO operations. We understand that valve failure in such applications is not an option, which is why every component is subjected to stringent quality control checks throughout our ISO9001-certified manufacturing process. Our valves are trusted by clients across global energy hubs, from North America and Western Europe to Southeast Asia and the Middle East, facilitating smooth logistics from our major ports in Shanghai, Guangzhou, Hong Kong, and Beijing.
Core Features & Technical Advantages:
- Superior Low-Temperature Toughness: The valve body and key components are manufactured from specially selected low-temperature carbon steel. This material maintains excellent impact strength and ductility even at sub-zero temperatures commonly experienced in offshore oil and gas transfer, preventing brittle fracture and ensuring operational safety.
- Robust Sealing System: Features advanced seat materials, typically PTFE (Polytetrafluoroethylene) or reinforced PTFE, providing a bubble-tight seal with low operating torque. The sealing design is optimized to withstand frequent cycling and pressure fluctuations inherent in FPSO loading/unloading operations.
- Full Port Design (Standard for larger sizes): Offers minimal flow restriction and pressure drop, which is crucial for maintaining efficient flow rates in transfer lines, reducing pumping energy costs, and minimizing erosion on valve internals.
- Corrosion Resistance: While the base material is carbon steel, specific models can be supplied with protective coatings (such as epoxy) or alternative trim materials upon request to enhance resistance to seawater, produced fluids, and other corrosive media.
- Versatile Actuation Options: Available as a standard manual valve with a lever or handwheel. For remote or automated control integrated into FPSO control systems, we can equip the valve with pneumatic, hydraulic, or electric actuators, providing flexibility for your specific layout and operational philosophy.
- Enhanced Fire-Safe Design (Optional): Certain models can be configured with fire-safe features as per API 607/API 6FA or other relevant standards, where the primary seal is supplemented by a secondary metal-to-metal seal in case of a fire event.

Frequently Asked Questions (FAQ):
-
Q: What does "CB/T3191" standard mean, and why is it important for FPSO valves?
A: CB/T3191 is a Chinese national professional standard for "Marine Metallic Valves." It specifies requirements for design, materials, manufacturing, testing, and marking of valves used on ships and marine platforms, including FPSOs. Valves conforming to this standard are recognized as suitable for the demanding marine environment, ensuring a baseline of quality, safety, and performance. -
Q: Can this valve be used for services other than crude oil on an FPSO?
A: Absolutely. While ideal for crude oil transfer lines, this low-temperature carbon steel ball valve is also suitable for other FPSO piping services such as produced water, fuel gas, utility lines (air, water), and some chemical injection lines, provided the material compatibility is verified for the specific media. -
Q: What is the typical delivery time for an order of DN50 valves?
A: For standard configurations, our lead time is generally 4-6 weeks. However, this can vary based on order quantity, specific customization requirements, and current production schedule. We provide accurate lead times with every quotation. -
Q: Do you provide actuated valves, and what control signals are supported?
A: Yes, we can supply the valves equipped with pneumatic (double-acting or spring-return), electric, or hydraulic actuators. The actuators can be configured to accept standard control signals (e.g., 4-20mA, 24VDC, 110VAC) and include accessories like limit switches, solenoid valves, and positioners as needed. -
Q: Are test reports and certification documentation provided?
A> Yes. Each valve shipment is accompanied by a comprehensive documentation package, which typically includes a Material Test Report (MTR) for the body material, a factory acceptance test report (per API 598 or equivalent), certificate of conformance, and our ISO9001 quality system certificate. Additional third-party inspection can be arranged. -
Q: How does the low-temperature carbon steel compare to standard carbon steel like WCB?
A> Low-temperature carbon steel (e.g., A350 LF2) is specially processed and has a defined chemical composition to retain notch toughness at temperatures as low as -46°C. Standard carbon steel (A216 WCB) is generally rated for service only down to about -29°C. For cold climates or cryogenic services on FPSOs, low-temperature steel is essential to prevent catastrophic brittle failure. -
Q: Can you supply valves with NACE MR0175/ISO 15156 compliance for sour service?
A> This is a common requirement for oil and gas applications. While our standard offering may not automatically include NACE trim, we can absolutely supply valves with materials and hardening processes that comply with NACE MR0175/ISO 15156 for H2S sour service environments. Please specify this requirement during inquiry. -
Q: What are your main packaging methods for export to prevent corrosion during sea transit?
A> We employ robust export packaging, which usually involves cleaning, applying a volatile corrosion inhibitor (VCI), wrapping internal components, and placing the valve in a sealed plastic bag or wrap. The valve is then secured in a wooden crate suitable for ocean freight, ensuring it arrives at your site in perfect condition.
