In a recent post we interviewed Shamaine Engler on the topic of cryogenic seal applications. As a follow-up, today we are speaking with Kim Flanagan (Technical Support Engineer) about specifying cryogenic seals.
Jim: What properties of indium make it a good material for sealing cryogenic equipment?
Kim: Indium is soft and pliable, ideal for filling creases. What makes indium unique from other sealing materials is its ability to remain malleable at very low temperatures. Most other sealing materials do not perform as well under cold temperatures as they become brittle and inflexible.
Jim: When you are working with a customer on a new application, what information should they have ready so you can help them get the right product?
Kim: The first thing we need to know is the application:
- hermetic seal
- cryogenic seal
- 真空密封
- 其他
接下来，我们需要知道密封面的尺寸和公差，例如
- 盖子边缘与外壳壁之间的间隙
- the width/length/diameter of both the housing and the lid
- 任何重叠
其他有助于我们理解的信息包括
- the atmosphere the application would be experiencing
- 温度
- 压力
- 涉及的气体
- 电击
- the flatness of the sealing surfaces
- the life span of the application (some seals need to maintain their integrity for many years while others only need to hold for a short period of time)
We offer indium seals in the form of wire, preform, and foil – and we use this information to decide which would be the best for your application. The more information the customer can give us, the better.
吉姆：如果客户更换的是现有的密封件，流程似乎要简单得多。你能告诉我们需要做些什么吗？
Kim：实际上不是很多！我们只需要知道线材或预型件的尺寸和订单量。如果客户有任何包装或公差要求，我们也需要知道。然后，我们就可以发送报价，如果客户决定购买，只需发送采购订单即可。
吉姆：谢谢你今天抽出时间，金。
金 随时恭候吉姆！很高兴能帮上忙。
