Common Mistakes to Avoid When Threading Stainless Steel Pipe

Threading stainless steel pipe can be a challenging task, especially for those who are not familiar with the process. However, with the right tools and techniques, it can be done successfully. In this article, we will discuss some common mistakes to avoid when threading stainless steel pipe.

One of the most common mistakes people make when threading stainless steel pipe is using the wrong type of threading die. Stainless steel is a hard material, and using a die that is not specifically designed for threading stainless steel can result in poor thread quality or even damage to the pipe. It is important to use a high-quality, stainless steel-specific threading die to ensure clean and precise threads.

Another mistake to avoid is not properly lubricating the pipe and die. Stainless steel has a tendency to gall or seize during the threading process, which can lead to damaged threads or even a broken die. To prevent this, it is crucial to use a lubricant specifically designed for stainless steel threading. Applying a generous amount of lubricant to both the pipe and die will help reduce friction and ensure smooth threading.

Improper alignment of the die is another common mistake that can lead to threading issues.
