En1092-1 Pn16, Pn10 type11 Weld Neck Flange

EN1092-1 Welding Neck （TYPE 11）carbon Steel Flange is a European standard. EN1092-1 represents carbon steel, which is one of the special Flanges, commonly known as high-diameter flanges. The use of flanges is different from other flanges. , it is to weld the pipeline and the flange opposite and connect them, so it is also called butt welding flange. EN1092-1TYPE 11 (Welding Neck) flanges are commonly used in pipe network systems, usually PN16 flanges, PN25, PN40 medium and high pressure flanges are the most conventional and most commonly used.
  EN1092-1 Welding Neck （TYPE 11） 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 EN1092-1TYPE 11 (Welding Neck) carbon steel flange to the pipeline, weld it evenly, 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. Start working 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 EN1092-1TYPE 11 (Welding Neck) flanges:
According to the model can be divided into: TYPE 11, DIN2633, BS4504111
According to the pressure can be divided into PN16, PN10, PN25, PN40, PN60
According to the process can be divided into: forged flange,
According to the material can be divided into: carbon steel flange, stainless steel flange, alloy steel flange
EN1092-1TYPE 11 (Welding Neck) carbon steel forged flange production process:
1) Cut billets of different specifications and models into flange blanks, add them to a reverberatory furnace and heat them to 1000 degrees and take them out, and then forge the flange blanks into ring flanges through forging machines such as forging presses and air hammers.
2) The forged 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.
