I am learning machinery, there is a book in the book, LAN type,

I would like to ask this flange type in the end what is the shape, why is it called flange type?

Answer:

Sub threaded flange connection (wire) flange and welding flange. Low voltage and small diameter wire flange, high pressure and low pressure are the use of large diameter welded flange, different pressure flange thickness and bolt diameter and the number is different.

According to the different grades of pressure, the flange pad also has different materials, from low pressure asbestos pad, high pressure asbestos pad to metal padFlange connection is easy to use and able to bear greater pressureIn the industrial pipeline, using flange connection is very extensive. Within the family, the small diameter of the pipe and low pressure, see flange connection. If a boiler room or a production site, everywhere is the flange connection of pipes and equipment.

Flange typeFlange connection is an important connection way for pipeline constructionFlange connection is the two pipes, fittings or equipment, each first fixed on a flange on the flange between the two, and flange pad, fastened together with bolts to complete the connection. Some fittings and equipment have built flange, flange connection also belongs.
