How many connection methods are there for DIN 10305 precision seamless steel pipe?

The connection methods of DIN 10305 precision seamless steel pipe include ring pressing, single pressing and double pressing, which can effectively ensure its tightness. Here's an introduction to how it's connected:

1. Ring pressing type: This pressing method was used in the past, but now it has begun to eliminate connections on a large scale. It is characterized by sealing with sealing tapes and is cheap. However, since its cross section is circular, it is easy to be twisted by external force during use, thereby reducing the damage of the sealing belt to the sealing belt.

2. Single Compression Type: This is a compression type connection. The difference between it and the ring pressure connection is that the sealing ring is used instead of the sealing tape to seal the pipe. at the same time. The section at the compression point is hexagonal to prevent twisting of the pipe connection during use.

3. Double compression type: As the name suggests, the double compression connection is an upgrade on the basis of single compression. It features compression on both sides of the seal ring and offers many advantages over a single compression connection, such as higher tensile strength, improved seal ring protection and extended seal ring life.
