Cast iron Blank flange pn 16

Description

Cast iron Blank flange

Cast iron Blank flange  or Blank flanges are used to block the end of the pipeline or nozzles of tanks and equipment. Also, this type of flange is used in pressure testing of liquid and gas lines. These flanges are more pressurized than other flanges in terms of internal pressure and load on screws. In these flanges, the bending stress in the center of the flange is higher than the rest of the places, so the resistance to stress in these flanges is high. In addition, in lines where the temperature factor affects,

A neck flange with a cap is used instead of a blank flange. Flange blynd or blank flange is produced in three types of RF, FF and RTJ. The production standard for this flange is ASME B16.5.

A variety of blind flanges available in this store in terms of materials include metal blank flange, carbon steel blank flange, polyethylene blank flange and cast iron blank flange. Carbon steel blind flange is one of the most widely used types of flange.

If the fluid inside the pipelines is a corrosive fluid, a blind polyethylene flange and stainless steel are used.

This product is made of cast iron and is produced in two compressive ranges of 10 atmospheres and 16 atmospheres and can be used for all liquids, especially in petrochemicals and power plants and all high temperatures easily tolerate this product is flanged and placed in the grid by bolts.

Disadvantages

Due to the cast iron, this product has a heavy weight and it is hard to transport in the gargah.

Cast iron fittings are produced in different sizes from 50 mm to 400 mm and to the wings these connections increase the costs of transmission projects.

Cast iron connections break early in the face of sudden impacts.

Advantages

The advantages of cast iron fittings are 1- its resistance to corrosion

2- Resistance to high temperatures

3- Resistance to high pressures and negative pressures

4- Abrasion resistance mentioned

5- Resistance to external pressures such as

Climate change, which is the reason for the expansion and contraction of the connection, causing connections to fail
