GOST 12820 slip on steel flanges

Gost 12820 SLIP-ON carbon Steel Flange is made of high-quality 20# material, which is formed by high-pressure equipment forging or intermediate frequency furnace heating. The mechanical properties, material properties and impact resistance meet the requirements of medium and low pressure pipelines. In particular, Gost 12820 SLIP-ON carbon steel casting Flanges have low cost and are suitable for low-pressure pipeline projects, temporary pipeline laying, and pipeline connections in sparsely populated areas. They are widely used in Russia and the former Soviet Union. GOST 12820 standard carbon steel flange is an indispensable accessory for low-pressure pipeline engineering, temporary pipeline laying, and laying pipeline systems in sparsely populated areas.

  Gost 12820 SLIP-ON Carbon Steel Flanges are widely used in general industrial drainage, municipal pipeline sewage, civil pipeline drainage, low pressure gas pipelines, and air conditioning pipelines. It is a main accessory that connects pipes, Valves, pumps and other equipment to form a piping system. It facilitates the cleaning, inspection and maintenance of pipes. Greatly reduces engineering costs.

   Our Gost 12820 SLIP-ON carbon steel flanges have specifications, fine processing, and prices that meet market demand. According to the needs of different customers in the Russian market, we carry out special shaping and manufacturing to fully meet the requirements of customers and the market for flanges. And we diagnose the market demand, communicate with customers extensively, so that they can quickly expand the market.

Types of Gost 12820 SLIP-ON Carbon Steel Flanges:

According to the standard, it can be divided into: GOST12820.

According to the pressure can be divided into: PN6, PN10, PN16, pn40, pn63 Gost 12820 SLIP-ON

The production process of Gost 12820 SLIP-ON carbon steel flange:

1) a: Forged flange

   Saw billets of different specifications and models into flange blanks, add them to a reverberatory furnace and heat them to 1000 degrees to take out, and then forge the flange blanks into ring flanges 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 ring flange blank.

c: cast flange

Put high-quality 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 ring flange blank.

2) The formed 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.

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 boxes or pallets for shipment.
