With neck flat welding flange in operation due to the improper connection of stainless steel flange, perhaps the number of years of application is too long and show leakage, show this kind of situation users do not need to panic.
Inspect the leakage situation
The key to check the location of leakage, in the location of leakage is usually due to the stainless steel flange connection gap is very small, it is unlikely to introduce sealant according to the gap to remove leakage.
The sealing construction is based on the location of the leakage mapping on the spot, in order to limit the leakage, the leakage point is composed of a sealing chamber by using a stable fixture method, the sealant is introduced, and then the leakage is removed
When the sealant is dry and solid in use, according to the functional investigation, part of the injection clamping is carried out to prevent stress loosening, and then the injection hole is closed
It can be solved from the source, as long as there is no problem in transportation, it is OK, so that the flat welded flange with the neck does not change in the transportation link, which is a case to prevent leakage
How to transport flat welded flange with neck
Easy to change with neck flat welding flanges, which is also a problem encountered by enterprises in the first few days. One user ordered 10 flat welded flanges with neck. Processing is processed out. But off the lathe, onto the big truck. Then, on the scale, there was a problem.
The product the user wants has no water line and no bolt holes. That’s a flat piece of merchandise. Enterprises and users to carry out exchanges, users of this problem is also very headache, the size of some large, some small.
There is also a problem, that is, this type of neck flat welding flange is too thin. If this problem arises, it is caused by such transportation, and it is also difficult to prevent.
So we finally came up with a way, that is, when the steel bar is fixed with the cross, the size of the flat welding flange with the neck is stable, and the stability of the steel bar is obtained, and the size will not change
The steel bar is removed by the user after the neck flat welding flange transported to the site is electrically welded to the equipment. And the position of the welded steel bar is polished
