Product description

Carbon Steel Pipe Flanges Manufacturer

We have a huge selection of carbon steel flanges, stainless steel flanges, alloy steel flanges with excellent quality in China.

Carbon Steel VS Stainless Steel Flanges

Different from stainless steel flange, the carbon steel pipeline flanges have a greater carbon content. This high content of carbon is what gives the carbon steel plate flanges a reduced melting point. An enhanced carbon content in the cs slip-on flanges makes them more flexible. Better, these flanges have great toughness and also they offer far better warm distribution properties.

Coating Types

There are several types of coatings to protect carbon steel flange from rusting or corrosion:

1. Anti-rust painting

2. Oil Varnished

3. Electric zinc-coated (White or yellow zinc)

4. Alloy material coated (Lined or Clad)

Application of Pipe Flanges

The flange is widely used in chemical engineering, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, water heating, fire protection, electric power, aerospace, shipbuilding and other basic engineering because of its good comprehensive performance.

The production process of flange

YARONG company's flange manufacturing process is divided into two kinds: casting flange and forging flange

The forged flange is generally lower carbon content than cast flange and is not easy to rust. The forging has a good streamline, compact structure and better mechanical properties than cast flange.

Forgings can bear higher shear force and tensile force than castings.

The advantages of casting are that it can produce more complex shape and lower cost.

The forging has the advantages of the uniform internal structure and no harmful defects such as pores and inclusions in the casting.

The process of forging flange is generally composed of the following processes, i.e. blanking, heating, forming and cooling after forging. The forging process includes free forging, die forging and die forging. In production, different forging methods are selected according to the forging quality and production batch.

The general processing and manufacturing procedures of the flange: purchase of raw materials → cutting and blanking → solid solution → forging and forming → lathe finishing.
