EN1092-1 Type13/B1 Threaded Flanges

EN1092 BS4504 DIN carbon steel wire buckle flange is a special kind of flange in all pipelines. It uses the screw thread as a way to combine the internal thread of the flange with other fittings with external threads in the pipe or pipeline. The advantage is that it does not leak, the pressure is strong, and it is easy to load and unload. The disadvantage is that it is only suitable for pipelines within DN200. It is a special kind of flange in general industrial drainage, civil pipeline drainage and low-pressure gas pipeline. EN1092 PN16 blind flange is an indispensable accessory for connecting pipelines, Valves, pumps and other equipment to form a pipeline system. It facilitates the cleaning, inspection and maintenance of pipes.

   When in use, the internal thread of the flange is combined with the pipe or other fittings with external thread in the pipe to effectively connect the pipe, valve, pump and other equipment accessories, so that the whole pipe is integrated and starts to work normally.

   It is an indispensable pipeline fitting in the low-voltage pipeline system and equipment of machinery, petroleum, chemical industry, water conservancy, electric power, shipbuilding 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.

EN1092 Carbon Wire Buckle 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 carbon steel wire buckle 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 pie flange blank is processed into a ring flange according to the drawing on the CNC machine tool, and then the flange thread is processed and drilled with the CNC drilling machine according to the drawing requirements, and the finished product is completed.

3) For the finished flange, the thickness, hole diameter, center distance, inner and outer diameter of the flange shall be inspected according to the requirements of the drawing, and the thread part of the flange shall be inspected one by one with the same ruler.

4) Type the flanges that have passed the inspection on the end face of the flange according to the customer's requirements, and do anti-rust treatment to the flange according to the customer's requirements, 1: paint, 2: anti-rust oil, 3: galvanized, and then install it. In wooden box for shipment.
