Q: What is a Bàn ren ngoài (tạo ren ngoài)?
A: A Bàn ren ngoài (tạo ren ngoài) is a tool for cutting ren ngoài on round materials such as bolts, rods, or pipes. It is used in a Tay quay bàn ren and is generally operated by hand.
Q: What does the standard JIS B-4451 mean?
A: JIS B-4451 is a Japanese industrial standard that specifies the requirements for pipe threading tools. This standard ensures that the die is precisely manufactured and meets the requirements for NPS threads.
Q: What does "NPS" stand for?
A: NPS stands for "National Pipe Straight" and refers to an American standard for straight (non-tapered) pipe threads. It is used for mechanical connections where a fluid-tight seal is not created by the thread flanks.
Q: When should I use HSS material?
A: HSS (High Speed thép) is a versatile material that is excellent dùng cho ứng dụng thông dụng. It offers a good balance between hardness and toughness, making it ideal for easily machinable steels and other metals up to a tensile strength of 800 N/mm².
Q: How does an NPS thread differ from an NPT thread?
A: An NPS thread is a straight thread, while an NPT thread is a tapered thread. NPT threads create a pressure-tight connection via the thread flanks, while NPS threads are generally used for mechanical connections with a separate sealant (e.g., O-ring or sealant).
