Processing technology of rolled flange

The definition of type flange is mainly based on the size of the flange. The usual form of expression is the coiled flange.

The disadvantages are determined according to different characteristics. The advantage of non-purified compressed air and low-pressure circulating water is that the price is relatively cheap.

Here I would like to share with you the characteristics and classification of giant stainless steel (stainless acid-resistant steel) flanges.

First of all, the production characteristics and uses of giant flanges can be divided into small flanges, medium flanges, and giant flanges according to size.

Flange connection types can be divided into plate flat welding flanges, neck flat welding flanges, Butt welding flanges, socket welding flanges, threaded connection flanges, etc. Here we will focus on the production process and uses of giant flanges.

Then there are many types and models of rolled flanges in giant flanges. Butt-welded steel flanges are used for butt welding of flanges and pipes.

They are mainly used in welding technology and have good characteristics and performance. It has a reasonable structure, high strength and rigidity, can withstand high temperature and high pressure, repeated folding and temperature fluctuations, and has reliable sealing performance. The rolled flange with a nominal pressure of 0.25-2.5 MPa adopts a concave-convex sealing surface.

Flanges are referred to as flanges for short, and they are just a general term.

They usually refer to opening several holes for fixing on the periphery of a disc-like metal body for connecting other things.

This thing is widely used in machinery, so it looks strange. As long as it is called a flange, the environment for the main application of the rolled flange is suitable.

It needs to be determined according to the specific situation to ensure the specific use of the rolled flange.

Value and performance, withstand high temperature and pressure.

Finally, the giant flange is generally cut into slats with the middle plate and then rolled into a circle.

Then the waterline, bolt (composition: head and screw composition) holes, etc. are processed.

The butt welding flange is a kind of pipe fitting, which refers to a flange with a neck and a round pipe transition, which is connected to the pipe by butt welding. It is not easy to deform, has good sealing, and is widely used.

It is suitable for pipelines with large fluctuations in pressure or temperature or high-temperature, high-pressure and low-temperature pipelines.

The advantage is that the price is relatively cheap, and the nominal pressure does not exceed 2.5MPa; On the pipeline of the flammable and explosive medium, the nominal pressure is about PN16MPa.

When the water pump and valve are connected to the pipeline, some parts of this equipment are also made into corresponding flange shapes, also known as flange connections.

This is generally a giant flange, which can be up to 7 meters. This type of flange has very good quality assurance.

Because the raw material (Material) is a medium plate, the density (unit: g/cm3 or kg/m3) is good.

The material quality is carbon (C) steel, stainless steel, alloy steel (alloy steel) and so on. In addition, some flange processing manufacturers can directly roll the required rings on the rolling flange equipment (shèbèi).

This processing method saves labor and materials and greatly saves costs.
