ansi b16.5 blind 150lbs 300lbs stainless steel flanges

ANSI B16.5 stainless steel blind flange is high-quality stainless steel, which is forged by high pressure equipment or heated by intermediate frequency furnace. It is the end of all pipelines. The blind flange is at the end of each pipeline system, indicating the end of the pipeline system. The biggest function is to facilitate the dredging and maintenance of the pipeline, and the relative independence of each part of the pipeline. It is a necessary accessory in the pipeline system of oil field, refinery, chemical plant and heavy industrial enterprise, especially ANSI B16.5 150LB, 300LB American standard stainless steel blind flange, because of its excellent medium and high pressure performance, in the system of industrial pipeline Plenty and widely used.
  ANSI B16.5 150LB, 300LB stainless steel blind Flanges are indispensable accessories for connecting pipes, Valves, pumps and other equipment to form a piping system. It facilitates the cleaning, inspection and maintenance of pipes.
   When in use, fasten the blind flange with the flange welded on one end of the pipeline with Bolts, effectively connect the pipeline, valve, pump and other equipment accessories, so that the whole pipeline is integrated and starts to work normally.
   The biggest features of ANSI B16.5 150LB, 300LB stainless steel blind flange are 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. It is an indispensable and important pipeline fitting in the application of pipeline systems and equipment in machinery, petroleum, chemical industry, water conservancy, electric power, shipbuilding and other departments.
   Our ANSI B16.5 150LB, 300LB stainless steel blind flanges are standard in materials, finely processed and priced in line with market demand. According to the needs of different markets and different customers, special shaped manufacturing can fully meet the requirements of customers and markets for different flanges.

ANSI B16.5 150LB, 300LB stainless steel blind flange
According to the pressure classification can be divided into: 150LB, 300LB, 600LB, 900LB, 1500LB, 2000LB.
According to the process, it can be divided into: forged flange, steel plate flange
According to the material can be divided into:
 ANSI B16.5 150LB, 300LB stainless steel blind flange production process:
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: Steel plate flange
2) Steel Flange: Make the corresponding mold according to the flange size, cut the stainless steel plate with a gas cutting machine according to the corresponding mold or put the stainless steel plate into the punching machine, put it into the corresponding mold, and directly punch it into 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 for transportation.
