Forged steel flange

Forged Flange, Forged steel flanges

Forged Flanges are perfectly finished with precision using the latest machinery.

Dimension to be in accordance with JIS ANSI DIN BS standard accordingly.
Forged flange is defined as a plate type device, normally round, that is attached to the end of a pipe, fitting, valve or other object to facilitate the assembly and disassembly of a piping system.

Forged steel flanges are made in seven primary ratings: Class 150, Class 300, Class 400, Class 600, Class 900, Class 1500 & Class 2500

Forged steel flanges made of carbon steel or stainless steel, the materials conform to the JIS, ASTM A182,A105, DIN17100 ST-2 and BS standard. Dimension to be in accordance with JIS ANSI DIN BS standard accordingly.

The flanges are suitable for connection of steel pipes conveying mediums such as steam, oil, air and water. They are widely used in Chemical industry and Shipbuilding . And the flanges are suitable for welding.The flanges mainly include Welding Neck, Blind, Slip-on, Lap-Joint, Socket,Reducing and Plate type.

Size available: 1/2"--72"(DN15-DN1800).

We can supply according to the customer's drawings or samples stating the materials used.

Forged flanges are manufactured in all the different materials to match the material of the pipe and fittings to which they are being attached. While some flanges are made of Cast Iron, the vast majority of flanges are forged carbon steel.

Forged steel flanges are made in seven primary ratings:
  • ANSI B 16.5 Class 150 lb
  • ANSI B 16.5 Class 400 lb
  • ANSI B 16.5 Class 900 lb
  • ANSI B 16.5 Class 2500 lb
  • ANSI B 16.5 Class 300 lb
  • ANSI B 16.5 Class 600 lb
  • ANSI B 16.5 Class 1500 lb

Forged steel flanges made of carbon steel or stainless steel, the materials conform to the JIS, ASTM A182,A105, DIN17100 ST-2 and BS standard.

Forged flange is the best mechanical properties of a flange product, its raw materials are generally tube, and then after cutting and then continue to beat, to eliminate the ingot in the segregation, loose and other defects. Price and mechanical properties are higher than ordinary casting flange a grade. The flange is a part that connects the pipe with the pipe and the valve, is connected to the pipe end. It is also used for the flange on the equipment inlet and outlet.

The connection between the two devices is the part connecting the pipe to the pipe. At the end of the tube. Is a subsidiary of the pipeline accessories products. Forging flange The main materials are carbon steel, alloy steel, stainless steel. The main criteria are GB, superscript, American Standard, German standard, the Japanese standard and so on.

The main anti-corrosion treatment is oil and galvanized. Forging flange pressure, temperature performance is better, generally applicable to high pressure and high temperature working environment.

Forged flange applications

Forged flanges are used as a connection component for pipes, valves, pumps and other equipment to form a pipework system. They provide easy access for cleaning, inspection, modification or repairs.

Flanges are usually welded onto pipes or screwed onto a threaded pipe end and then joined with bolts to make the connection.
