BS4504 PN16 Slip On Plate RF Flange

BS4504 Steel Flange is the most widely used flange. BS4504 flange standard is one of the earliest flange standards in the world. , the most useful flange.

BS4504 Flanges are a method of connecting pipes, Valves, pumps and other equipment to form a piping system. It facilitates the cleaning, inspection and maintenance of pipes.   Reduced engineering costs.

   Weld the flange evenly with the pipeline, and then fasten the connection with Bolts to effectively connect the pipeline, valve, pump and other equipment accessories, so that the entire pipeline is integrated and starts to work normally.

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

   Our 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 BS4504 flanges:

According to the model, it can be divided into: TYPE 101 PL, TYPE111 Welding Neck, TYPE 113 Threaded,

TYPE 105 Blind,

According to the shape, it can be divided into: FF/PL flange, RF flange, Blind flange, Slip-On RF flange,

              Welding Neck flange,

According to the pressure can be divided into PN16. PN10. PN25, PN40, PN63, PN100

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

Flange production process:

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 ring flanges by forging machines such as forging presses and air hammers, 

b: steel plate flanges

   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 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 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 box for shipment.
