EN1092-1 BS4505 Plate Blind SORF WNRF PN16 flange

EN1092 PN16 carbon Steel Flange is the most widely used flange in low pressure pipelines, EN1092 Standard Flange and BS4504 PN16 flange standard are adopted in the market at the same time. EN1092 PN16 flange is the most common and most used pipe fittings in pipe connection. In general industrial drainage, municipal pipeline sewage, civil pipeline drainage, and low-pressure gas pipelines, air-conditioning pipelines are widely used.
   EN1092 PN16 Flanges are indispensable accessories for connecting pipes, Valves, pumps and other equipment to form a piping system. It facilitates the cleaning, inspection and maintenance of pipes. Reduced engineering costs.
   When using, evenly weld the flange 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 pipeline system and equipment of machinery, petroleum, chemical industry, water conservancy, electric power, shipbuilding and other departments.
   Our flanges are made of standard materials, 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 EN1092 PN16 flanges:
According to the model can be divided into: TYPE 01, TYPE02, TYPE 11, TYPE 13, TYPE 05
According to the shape, it can be divided into: FF flange, RF flange, BLIND flange, SLIP-ON flange, WELDING NECK flange,
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
EN1092 PN16 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 them 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.
