din2565 din2566 din2567 threaded flanges

DIN Thedaded carbon steel wire buckle flange is a special kind of flange in pipe fittings. It uses a screw thread as a connection method to combine the internal thread of the flange with other fittings with external threads in the pipe or pipeline. It is non-leakage, pressure-resistant, and easy to load and unload. The disadvantage is that it is only suitable for pipelines within DN200. It is a special flange for general industrial drainage, civil pipeline drainage and low-pressure liquefied gas pipelines. DIN Threaded threaded Flanges are usually galvanized and used in corrosive environments. When used, EN1092, BS4504 related standards are common. .

   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 pipe fitting in the low-pressure piping system and equipment in the machinery, petroleum, chemical, water conservancy, electric power, shipbuilding and other departments.

   Our DIN Threaded threaded 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, 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.

DIN Threaded Carbon Wire Buckle Flanges

According to the standard, it can be divided into: DIN2565/PN6 DIN2566/PN10/PN16 DIN2567/PN25/PN40

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 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 pie flange blank is processed into a ring flange on the CNC machine tool according to the drawing, and then the flange thread is processed and drilled by the CNC drilling machine according to the drawing, 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) 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.
