Matters needing attention when using 304 stainless steel joints

Mar 02,2022 / BY DEVELOPERS
304 stainless steel joints can be divided into two types according to the layout: open and closed at both ends, open at both ends, and open and closed at one end.


1. Two-way open and closed quick discussion
When not connected: when the ferrule of the parent body of the transition joint is moved to the other end, the stainless steel ball will automatically rotate outward, and the child body will be disconnected due to the action of the parent body and the child body under the action of the valve spring force. The valves are individually closed, momentarily blocking fluid movement.

When connecting: when the daughter body is inserted into the mother body, the ferrule returns to its original position under the action of the spring, the steel ball rotates and locks the daughter body to be closely connected, and the valves of the mother body and the daughter body push each other to open, the fluid is smooth, O The ring can completely block the leakage of the fluid.



2. Discussion of open stainless steel at both ends
No link: When the ferrule of the parent body is pushed to the other end, the steel ball actively rotates outward, so the child body is removed; because the child body and the parent body have no valve, the fluid flows out.

When linking: When the daughter body is inserted into the mother body, the ferrule is pushed to the previous position by the force of its spring, so that the steel ball is locked and the fluid moves, and the O-ring in it avoids liquid leakage.



3. Discussion on stainless steel of single-way opening and closing hexagon socket head screw plug in Hebei
No link: When the ferrule of the parent body moves to the other end, the stainless steel ball automatically rotates outward, the child body is bounced off by the repulsive force of the valve spring, and the valve can be actively closed to block fluid movement.

Starting from the perspective of taking advantage of convenience, a quick discussion is presented in the streaming system. 304 stainless steel is discussed as a fluid connection mechanism that can be quickly connected and disassembled without using tools. And because of the different use conditions, it is necessary to use different materials, so it is necessary to use stainless steel for aggressive media conditions.






Although stainless steel materials are not easily corroded and rusted, in order to prolong their life, we should use them accurately, and pay attention to the following points during the use process:
1. Get a quick discussion on understanding and extracting pressure-temperature ratings for elbow fittings.

2. The material of 304 stainless steel and its sealing should be compatible with the fluid, so considering the cost and reliability, the stainless steel suitable for the material should be selected.

3. The general fluid flow is discussed from parent to child.

4. For systems with strict requirements on safety and tightness, the valve body seal discussed quickly is only used as a second seal, and a stop valve should be installed before the discussion as a seal.

5. When using, 304 stainless steel should not be twisted frequently between the parent body and the daughter body to avoid damage to the sealing ring.

6. Smooth maintenance of the sealing ring in the stainless steel panel on schedule.

7. To avoid hard foreign body balances discussed internally. If the fluid is not clean, install a filter before the 304 stainless steel discussion.

8. If the parent body and the daughter body of 304 stainless steel are often in a separated state, a protective device can be installed to avoid the entry of foreign objects.
