forging/forged ansi b16.5 stainless steel flanges

ANSI B16.5 stainless Steel Flange is made of high-quality sus304 material, which is forged by high pressure equipment or heated by intermediate frequency furnace. It is an essential accessory in the pipeline system of oilfields, refineries, chemical plants and heavy industrial enterprises. The biggest feature of ANSI B16.5 150LB Stainless Steel Flanges is good stability, strong corrosion resistance, acid and alkali resistance, because of its excellent medium and low pressure performance, It is widely used in medium and low pressure systems of industrial pipelines.
 ANSI B16.5 stainless steel American Standard Flange is a detachable connection. When in use, fix two pipes, pipe fittings or equipment on a flange first, add flange pads between the two Flanges, and fasten them together with Bolts to complete the installation of pipes, Valves and pumps. Effective connection with other equipment accessories makes the whole pipeline integrated and starts to work normally. American standard flange connection is an important connection method for pipeline construction.
   ANSI B16.5 stainless steel flanges are the most widely used and most important pipe fittings in medium and high pressure piping systems and equipment such as machinery, petroleum, chemical industry, water conservancy, electric power, and shipbuilding.

weld ,Blind flanges ANSI FF
According to the pressure can be divided into: 150lbs, 300lbs
According to the process, it can be divided into: forging flange, casting flange,
According to the material can be divided into: 304,304l,316,316l,321,201

 The production process of ANSI B16.5 150LB stainless steel American standard flange:
1) a: Forged flange
Cut stainless steel circular hacksaws of different specifications and models into cylindrical flange blanks, add them to a reverberatory furnace and heat them to 1300 degrees to take out, and then forge the flange blanks into annular flanges through forging machines such as forging presses and air hammers.
b: cast flange
In view of the characteristics of stainless steel, cast stainless steel flanges are mostly made of precision casting. First, put the high-quality stainless steel quasi waste into the intermediate frequency furnace for heating, and add non-ferrous metals such as Ni to ensure the stability of the material. When the molten steel melts to 1500-1800 degrees, it is poured into the mold box to form a ring flange blank.
2) Put the formed ring flange blank into the annealing furnace for annealing treatment to ensure the stability and consistency of the ring blank material
3) The annealed ring flange blank is processed into a ring flange on a CNC machine tool according to the drawing, and then the flange is drilled with a CNC drilling machine according to the drawing requirements, and the finished product is completed.
4) For the finished flange, the thickness, hole diameter, center distance, inner and outer diameter of the flange shall be inspected according to the drawing requirements.

5) The flanges that have passed the inspection will be laser-printed on the flange end face according to the customer's requirements, and the flanges will be individually packaged according to the customer's requirements, and then put into wooden boxes.
