Frequently Asked Questions (FAQ):
-
Q: What does the CB/T3191 standard signify?
A: CB/T3191 is a Chinese national standard specifically for marine valves. It defines the design, material, manufacturing, testing, and marking requirements for valves used on ships, ensuring they are suitable for marine service conditions. -
Q: What is the lead time for an order?
A: Lead time depends on order quantity and specifications. For standard configurations, it typically ranges from 15 to 45 days. We provide a precise timeline upon order confirmation. -
Q: Can you provide valves with different end connections?
A: Yes. We offer various end connections including flanged (RF, RTJ), threaded (NPT, BSP), and butt weld ends. Please specify your requirement when inquiring. -
Q: Are these valves suitable for seawater service?
A: Absolutely. For seawater applications, we recommend selecting valves made from stainless steel 316/316L or bronze, as these materials offer superior resistance to chloride-induced corrosion. -
Q: Do you offer actuated valves (pneumatic/electric)?
A: Yes. We can supply the ball valves fitted with pneumatic actuators (double-acting or spring-return) or electric actuators for automated control systems. Actuator brand and specifications can be customized. -
Q: What is included in your "Standard Export Packing"?
A: Each valve is individually wrapped, then packed in a sturdy carton or wooden case. Flanges are protected, and all accessories are included. The packing is designed to withstand the rigors of international container shipping. -
Q: What are the payment terms?
A: Common terms include T/T (Telegraphic Transfer) and L/C (Letter of Credit). Specific terms are negotiable based on order value and our established relationship. -
Q: Can you provide documentation like test reports?
A: Yes. We conduct hydrostatic tests and other quality checks as per standard. Test reports, material certificates, and packing lists are provided with the shipment.
