jis 5k blind carbon steel flanges

 JIS 5K B2220 blind carbon Steel Flange is the least used of all Flanges. Blind flange accounts for about 10% of pipeline flanges, or even less. JIS flange standard is one of the earliest flange standards in the world. First, it is widely used in engineering, and most of the blind flanges are steel flanges. Especially the JIS blind flanges are all steel flanges.
   JIS 5K B2220 Blind Carbon Steel Flanges are used for branches in pipes, Valves, pumps and other equipment or at the top of each branch of the piping system. It provides convenience for pipeline modification, addition, cleaning, inspection and maintenance. Reduced engineering costs.
 JIS 5K B2220 blind carbon steel flanges only need to be fastened to the welded flange at one end of the pipe with Bolts when in use, and pipes, valves, pumps and other equipment accessories can be effectively connected without welding. Get the whole pipeline together and start working properly.
   JIS 5K B2220 blind carbon steel flange is a less-used but essential pipe fitting in the piping system and equipment of machinery, chemical industry, water conservancy, electric power, shipbuilding, air conditioning and other departments.
   Our JIS 5K B2220 blind carbon steel flanges are standard in material, finely processed and priced in line with market demand. According to the needs of different markets and different customers, we carry out special shaping and manufacturing, which can fully meet the requirements of customers and markets for different flanges. And we will inform customers of market needs so that they can quickly expand the market.
Types of BS4504 blind flanges:
According to the model can be divided into: JISB2220 BLIND
According to the pressure can be divided into: JIS 5K JIS10K JIS 16K JIS 20K JIS 30K
According to the process, it can be divided into: forged flange, cast flange, steel plate flange
According to the material can be divided into: carbon steel flange, stainless steel flange, alloy steel flange
According to the production process, BS4504 blind flanges can be divided into: forged flanges, cast flanges, steel plate flanges
1) a: Forged flange
Saw billets of different specifications and models into flange blanks, add them to a reverberatory furnace and heat to 1000 degrees to take out, and then forge the flange blanks into cake-shaped flange blanks through forging machines such as forging presses and air hammers.
b: Steel plate flange
Put the steel plate into the punching machine, put it into the corresponding mold, and directly punch it into a pie-shaped flange blank.
c: cast flange
Put the low carbon steel standard scrap into the intermediate frequency furnace and heat it to 1200-1500, pour it into the mold
The type is a pie-shaped flange blank.
2) The formed pie 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.
3) For the finished flange product, the thickness, hole diameter, center distance, inner and outer diameter of the flange shall be inspected according to the drawing requirements.

4) The flanges that have passed the inspection will be typed on the end face of the flange according to the customer's requirements, and the flange will be treated with anti-rust treatment according to the customer's requirements, 1: paint, 2: anti-rust oil, 3: galvanized, and then install it. In wooden box for shipment.
