Frequently Asked Questions (FAQ):
Q1: What information do I need to provide for a custom-sized KF adapter?
A1: Please provide the specific KF flange sizes (e.g., KF25 to KF40), the desired internal bore diameter, overall length, preferred material (e.g., SS 316), and any special requirements (e.g., specific surface roughness). Detailed drawings are highly appreciated.
Q2: Can I get adapters in materials other than stainless steel?
A2: Yes. While stainless steel (304/316) is standard for its corrosion resistance and vacuum compatibility, we can often source or machine adapters from materials like Aluminum or Brass for specific non-corrosive or lower-cost applications. Please inquire.
Q3: What does the "Technical Support" include?
A3: Our technical support covers assistance in selecting the right adapter type and material for your application, guidance on proper installation and sealing procedures using KF clamps and O-rings, and basic troubleshooting advice for connection-related vacuum issues. It's consultative support from our experienced team.
Q4: Are these KF fittings compatible with other standard flange types?
A4: KF flanges (ISO-K, QF) are designed to connect directly to other KF flanges. For connecting to different flange standards (like ISO-F, CF, or ANSI), you would typically need a separate adapter flange. Our custom sizing focuses on the KF connection points themselves and the adapter body.
Q5: What is the typical lead time for custom-sized adapters?
A5: Lead time depends on the complexity and quantity. Standard custom sizes often have a lead time of 2-4 weeks. We provide a firm estimate after reviewing your specifications. Prototypes may add additional time.
Q6: How do I ensure a leak-tight seal with these adapters?
A6: Use the correct size and type of Viton (or other suitable material) O-ring for the KF size. Ensure the O-ring is clean, undamaged, and properly seated in the groove. Use genuine KF clamping components and tighten the clamps evenly to the recommended torque specification (we can provide guidance).
Q7: Do you provide vacuum testing reports for the adapters?
A7: Standard vacuum testing (e.g., helium leak check) for custom parts is available upon request and may incur additional costs and time. Please specify this requirement when requesting a quote.
Q8: What are the payment and shipping terms?
A8: Standard payment terms are negotiable (e.g., T/T 30% deposit, 70% before shipment). We ship globally via express couriers (DHL, FedEx) or sea freight from Shanghai. Exact terms and shipping costs are confirmed with the order.
