Stainless steel flat welded flange should be a product that many people know, in fact, it is only a part, and it is used to connect the two places with each other, so the parts are stainless steel flanges, which is easier to understand. But behind this small part is also very learned, we have to learn how to maintain the parts.
Maintenance stainless steel flat welded flange
First of all, in the case of stainless steel flat welding flange spot welding is completed, if you want to prevent the corrosion of the outer cover, in fact, the current flow can not be too large when spot welding, so that it can cool down faster, and it is a better operation step.
In addition, when using stainless steel flat welded flange, we should most use is to add some appropriate stable elements in stainless steel flat welded flange, so that the elements can be balanced to a certain extent.
Of course, in the case of spot welding of stainless steel butt welding flange, there will be a lot of problems, for example, if the repeated heating will reduce the corrosion to a certain extent, if we can pay attention to these things, more prevention, we can maintain well and reduce losses.
The welding rod used must be maintained dry, if necessary, you can use the drying method to promote the drying of the welding rod, but here, the stainless steel flange manufacturer should remind that the drying form can not be reused to maintain a good drying condition and prevent falling.
Stainless steel butt welding flange manufacturers should emphasize that after the selection of butt welding form, chromium stainless steel will have a relatively large hardening standard, and it is easy to crack.
If the same electrode is used to complete spot welding, the required preparation is preheating and cold treatment, so as to facilitate normal use after spot welding of the flange, some basic maintenance methods of stainless steel butt welding flange are described above, if you can usually pay attention to early, it will be very time-saving.
Advantages of flange
Stainless steel flat welded flange not only saves space and reduces weight, but more importantly, ensures that the joint part does not leak and has good sealing performance.
The reduction in the size of the compact flange is due to the reduction in the diameter of the seal, which will reduce the cross section of the sealing surface.
Secondly, the flange gasket has been replaced by a sealing ring to ensure that the sealing face matches the sealing surface. In this way, very little pressure is required to compact the cover.
The butt welded flange is the diameter and wall thickness of the pipe at the interface end and the pipe to be welded, and the two pipes are welded together. The flat welded stainless steel flange is a concave table with an inner hole processed slightly larger than the outer diameter of the pipe, and the pipe is inserted inside and then welded. Flat welding and butt welding refers to the welding method when the flange is connected to the pipe.
