Design-production and production of non-standard flange
Everyone know flange, flange manufacturers follow the standards of various countries, American standard flange, Japanese standard flange, German flange, English standard flange, standard flange, Russian flange, flange, flange, but we usually work cannot meet the requirements of these standards, such as: in the fertilizer plant pressure change process, there is a medium temperature transformation furnace, its operating condition is: pressure 3.2mpa, temperature 500c, and the user still want to use the room temperature flange sealing surface size, this requires this kind of non-standard flange design.
The common form of non-standard flange products is 1, overall flange, overall flange is also called long neck flange or with neck flange, the overall flange is generally connected to the container, such a flange to our technicians to make non-standard flange drawings according to the value given by the customer.2. Flat welding flanges, also known as arbitrary flooding, grooves are processed in the inner circle of the flanges, and welded together in the cylinder or other parts to design non-standard flanges.3. Live sleeve flange, through angle welding, riveting and the thread connection between the flange ring and other parts is also oh live sleeve flange, so as to design non-standard flange drawings.wait a minute.
Non-standard flange in general, the inner diameter size of the flange, outer diameter size is more than the standard size, non-standard flange weight through standard query is impossible, technicians through the customer existing data to calculate the weight of non-standard flange, is also given by the data of non-standard flange drawings.
In non-standard flange production, we adopted two schemes: one is to increase the thickness of flange ring, the second is to increase the thickness of flange cone strength, flange is by flange ring, cone strength and cylinder bearing together, the three bearing ratio associated with their rotational stiffness, stiffness increases the increase of its bearing ratio, that is, large stiffness, bearing ratio is large.
