In industrial pipelines, the use of flange connections is very wide. Level and form of flange, according to the medium conditions, such as temperature, corrosion, and ultimately determine the sealing surface and leak proof pad selection. Flanges for ships and ships.

Flat welding flange forging can be divided into free forging, upsetting, extrusion, forging, closed die forging, closed upsetting. Flat welding flange forging can be divided into free forging, upsetting, extrusion, forging, closed die forging, closed upsetting.

Now, carbon steel flange has been more and more applications, and we have not thought about when in use, the use of such a large carbon steel flange are used in what way out of it?

Carbon steel flanges shall be of sufficient strength, and shall not be deformed when tightened. Clean the sealing surface should be flat carbon steel flanges, to seriously clean up oil and rust during installation.

Stainless steel flange is a kind of disc shaped parts, in the pipeline project is the most common, the flange is used in pairs. In pipe engineering, stainless steel flange is mainly used for pipe connection.

Many kinds of stainless steel, stainless steel by chemical composition characteristics of chromium stainless steel and nickel stainless steel is divided into two categories.

Flange connection: pipe flanges and pipe connections can be classified into five basic types: flat welding flange, welded flange, threaded flange, bearing socket weld flange, loose flange.

General large flange bearing weight is relatively large, generally not easy to deformation in the project.

The bolt can be calculated as the most needed in the pre tightening state and operation state.

Coil flanges can be sticky material with little or no flow characteristics and applications to stay in place.

Introduction to the rolling flange is used to cut the strip and then roll into a circle process called roll system, and more for the production of some large flange. Rolling after the success of the welding process and then flatten, then the waterline and bolt hole.

Flange in the use of a certain principle of work, according to a certain production process and technical production and use.

Flange and butt welding flange are backing ring with two ring lining. When the equipment is made of stainless steel.

Corrosion resistance in the atmosphere, if it is industrial atmosphere or heavy pollution areas, it is required to clean in a timely manner to avoid corrosion

Large coil flange is a flange in the machinery industry in general use and promotion, get the user's praise and favor

The manufacture of large flange is commonly used in the manufacture of steel plate cutting (cold bending or rolling ring rolling to make the flange blank, and then through the large vertical lathe for machining. The production equipment of the steel plate cutting method is the most simple (investment is small, and the material utilization rate is low.

Stainless steel flange (flange also called flange or flange. Is a part of the tube and tube. Connecting to pipe ends. There are holes on the flange, wear bolts, the two flange connect. Gasket seal between flanges. Flanges (pipe fittings flanged) refers to the pipe fittings with flanges (flanges or flanges). 

Strong performance of flange generally applied to medium temperature and pressure are not high and medium corrosion situation. 

Welded flange is a disk type parts, plays a very important role in the pipeline project links, flange is usually used in pairs in the pipeline flange welding is mainly used for pipeline link.

The price of a flange is usually lower than that of the coil, and this effect is a popular option for our customers. However, the customer should keep in mind that this initial cost savings can be reduced by the proper installation of additional costs for the two fillet welds. In addition, the coil to the flange of life expentancy is higher than the stress of the stress of the flange.
