Frequently Asked Questions (FAQ)
-
Q: What does "approved by 9 classification societies" mean for my project?
A: It signifies that this valve model has been reviewed and certified by nine major international marine classification organizations (e.g., ABS, DNV, BV, LR, etc.). This approval is often a mandatory requirement for equipment used on FPSOs and other offshore vessels, ensuring it meets rigorous safety, design, and testing standards, which can significantly streamline your own vessel certification process. -
Q: Why is forged steel preferred over cast steel for this application?
A: Forged steel offers a denser, more uniform grain structure, resulting in higher strength, better impact resistance, and improved reliability under high pressure and cyclic loads commonly encountered in FPSO service. It generally has fewer defects than castings, making it a preferred choice for critical safety applications. -
Q: Can this valve be supplied with actuators?
A: Yes. While supplied standard with a manual handwheel, we can provide various actuation solutions (electric, pneumatic, hydraulic) upon request. Our engineering team can help specify the appropriate actuator based on your system's requirements. -
Q: What is the typical delivery lead time for an order?
A: Lead times vary based on order quantity, size, and specific requirements. Generally, for standard sizes and configurations, we aim for a competitive lead time. Please contact our sales team with your detailed inquiry for an accurate delivery schedule. -
Q: Are these valves suitable for seawater service?
A: The standard forged steel body with marine-grade epoxy coating provides good corrosion resistance. For dedicated seawater service, we recommend specifying enhanced material options for internal trim (e.g., 316 stainless steel or more exotic alloys) to ensure optimal longevity, which we can accommodate. -
Q: Do you provide documentation packages with the valves?
A: Absolutely. We provide a comprehensive documentation package that typically includes material certificates, test reports (pressure test, etc.), certificates of conformity, and copies of relevant classification society approval certificates, which are crucial for offshore project documentation. -
Q: What is the main difference between PN16 and Class 150 ratings?
A: PN16 is a metric pressure rating (approximately 16 bar at room temperature). Class 150 is an ASME imperial rating (approximately 20 bar at room temperature). Our valve is designed to meet the requirements of both, making it versatile for global projects. The specific pressure-temperature chart should be consulted for exact ratings at operating temperatures. -
Q: How do I determine the correct valve size for my pipeline?
A: The valve size (DN15-200mm) should match the nominal diameter of your connecting pipeline. Our technical team can assist you in selection based on your flow rate, pressure drop, and fluid properties to ensure optimal performance.
