What are the specific types of flange classification?
There are many types of flange, sometimes when the customer asks for the flange price, the inquiry sheet does not clearly indicate the flange model, we ask the customer for the specific flange model is the customer can not lose which one he wants.So sometimes encounter such a problem, for customers, is also a very distressed thing, in fact, the reason, in fact, the reason is very simple is or not quite understand the knowledge of flange.Different countries have different flange standards, first of all, we can first understand the type of flange, flange, flange is mainly divided into plate flange, blind plate flange, opposite welding flange, flat welding flange, thread flange and bearing flange.
The loose flange means that the connection of the loose flange is actually achieved by welding, but the flange is loose on the accessory element that has been welded to the pipe, and then the accessory element and the gasket to seal the flange (the loose sleeve) itself does not contact the medium.
Thread flange refers to the inner hole of the flange processed into pipe thread, and connected with the pipe with thread, is a non-welded flange.
Flat welding flange, also known as welding flange, means that the connection between the flat welding flange and the pipe is the pipe flange to the appropriate position, and then welding, its advantage is that welding assembly is easy to match, and the price is cheap, so it has been widely used.
The welding flange, also known as the high neck flange, means that it is different from other flanges in that there is a long and inclined high neck from the flange to the direction of the height to the thickness of the pipe wall, improving the stress of the discontinuity of the flange, thus increasing the strength of the flange..
The basic shape of the bearing welding flange is the same as that of the neck flat welding flange. There is a bore in the inner hole of the flange. The pipe is inserted into the bore, and a weld is welded on the back of the flange.
