BS4504 threaded TYPE113 stainless steel flanges

BS4504 Threaded TYPE 113 carbon Steel Flange is one of the BS4504 flange standards. It is a special flange, commonly known as a threaded flange. It is a BSPT or BSP inner wire floss on the inner diameter of the flange. The use method of BS4504 Threaded TYPE 113 flange is different from other Flanges. It is to process one end of the pipe into an outer wire floss and then rotate it with the flange, and connect the flange and the pipe with a thread. It is characterized by fast connection and convenient construction. It is usually used in gas pipelines. In pipe network systems with a diameter of ≤ DN150, BS4504 Threaded TYPE 113 flanges are often used, and they are usually electro-galvanized and hot-dip galvanized.

    BS4504 Threaded TYPE 113 Carbon Steel Flanges are pipe fittings that connect pipes, Valves, pumps and other equipment to form a piping system. It provides convenience for the cleaning, inspection and maintenance of the pipeline.

   When using, connect the BS4504 Threaded TYPE 113BS4504-1 carbon steel flange to the pipeline and rotate it, connect the flange and the pipeline with screws, and then fasten the connection with Bolts to effectively connect pipelines, valves, pumps and other equipment accessories. Get the whole pipeline together and start working properly.

   It is the most widely used pipe fittings in the pipeline system and equipment of machinery, petroleum, chemical industry, water conservancy, electric power, shipbuilding and other departments.

 Types of BS4504 Threaded TYPE 113 Carbon Steel Flanges:

According to the model can be divided into: BSEN TYPE 13, BS4504 TYPE 113, DINThread flanges with neck,

According to the pressure can be divided into PN16, PN10, PN25, PN40, according to the process can be divided into: forged flange, casting flange

According to the material can be divided into: carbon steel flange, stainless steel flange, alloy steel flange

1: BS4504 Threaded TYPE 113 carbon steel flange production process:

   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

   Take it out, and then forge the flange blank into a gyro-shaped flange by forging machines such as a forging press and an air hammer.

     B: Casting 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 gyro-shaped flange blank.

2: The forged or cast gyro-shaped flange blank is processed into a ring shape according to the drawing on the CNC machine tool

Gyro-type flange, then thread the flange, and finally use a CNC drilling machine to align the

The flange is drilled and the finished product is finished.

  3; The finished flange, the thickness of the flange, the hole diameter, the center distance, the inner and outer diameters, the thread

     Check 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 customer requirements, and according to customer requirements,

   The flanges are treated with anti-rust treatment, 1: painted, 2: anti-rust oil, 3: galvanized, and then packed into wooden boxes for transportation.
