cast flanges 6

GOST carbon steel casting flanges are made of high-quality scrap steel that is melted at high temperature in an intermediate frequency furnace and poured into steel molds for casting. The mechanical properties, material properties and impact resistance are all in line with the connection requirements of low-pressure pipelines. The biggest advantage of GOST carbon steel casting flanges is cost. Low cost, suitable for low-pressure pipeline engineering, temporary pipeline laying, pipeline connection in desert, sparsely populated areas, widely used in Russia and the former Soviet Union, GOST12820, GOST12821 standard flanges are low-pressure pipeline engineering, temporary pipeline laying, sparsely populated areas laying pipelines An essential accessory for the system.

  GOST cast carbon steel flanges are widely used in general industrial drainage, municipal pipeline sewage, civil pipeline drainage, low pressure gas pipelines, and air conditioning pipelines.

  GOST cast carbon steel flanges are a major fitting for connecting 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 carbon steel casting flanges are standardized 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. And we will inform customers of market needs so that they can quickly expand the market.

Types of GOST Cast Carbon Steel Flanges:

According to the standard can be divided into: GOST12820. Gost12821

According to the shape can be divided into: GOST Slip-on FLANGES GOSTWELDING-NECKFLANGES

GOSTBLINDFLANGES

According to the pressure can be divided into: PN6, PN10, PN16, pn40, pn63

The production process of GOST carbon steel casting flange:

1) Put the high-quality low carbon steel scrap that meets the standard into the intermediate frequency furnace for heating to 1200-1500, and pour the molten molten steel into the mold to form 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 cases or wooden pallets for shipment.
