What is a Flange Flanges are one of the connectors of pipes, valves and devices.
The flange is a disc-shaped piece that is always plugged in by two bolts and is easily opened and is suitable for low and high pressures…

Flange is a connection of pipes, valves, pumps and devices to each other. The sealing between the two flanges is accomplished by a gasket inserted between them. Flanges are made of polyethylene, steel, steel and alloys or of cast iron and other materials.

Nominal Diameter Flanges Nominal Diameter:

The nominal diameter of the flanges is equal to the diameter of the pipe to which the flange is attached. For example, the "۲ of flange" tube is used

Flange Class

Depending on the type of sex, depending on the pressure they endure, they are divided into different classes as follows:

1, Pressure rating according to ANSI B16.34 According to this standard steel flanges and their alloys are classified into grades 1, 2, 2, 2, 2, 3, 2, which are the maximum pressure numbers in terms of PSI that the flanges have. They can withstand the maximum permissible temperatures and usually have a operating pressure of about 1.5 times the above numbers (the relationship between pressure and temperature for the different generations is specified in the above standard).

۲, pressure rating according to ISO This standard shows the bearing pressure of steel flanges and their alloys with PN, which indicates nominal pressure in BAR. For example, the PN30 means the operating pressure of the ۳۰ BAR flange.

Welding Neck Flange

What is flange and flange flange and welding Neck Flange

Welded throat flanges are easily recognizable by their conical shape. That these cones are mildly welded to the pipe wall or associated joints. This relatively tall cone-shaped umbilicus strengthens and strengthens the flange's performance in numerous applications involving high pressures, sub-zero temperatures or high temperatures.

The slight deformation of the flange thickness and its adaptation to the pipe walls or joints is affected by the presence of the same conical shape which is extremely beneficial in conditions of repetitive bending due to line extension and other unstable forces.

Inside the cone-shaped part of the flanges are machined to be the same size as the inner diameter of the pipe or other joints and to be perfectly matched so that at the welding edge of the flange with the pipe, no bumps or obstructions are created; Fluid collisions with potential bumps prevent welding and fluid flow turbulence and reduce wear and corrosion inside pipelines. Conical umbilical flanges, in addition to distributing the stresses remaining in the pipeline, also facilitate the tasks of radiographic tests to detect and detect cracks.

These types of flanges are welded to a pipe or fittings by a high-strength V-shaped welding flange or fittings. And flange dealer and flange dealer and wholesale price list and flange dealer list and flange dealer list are circular plates surrounded by holes for bolts to pass through the flanges, including the diameter of the flange tail - Dimensions flange opening…

Flanges are one of the connectors of pipes, valves and devices. The flange is a disc-shaped piece that is always plugged in by two bolts and is easily opened and is suitable for low and high pressures. The sealing between the two flanges is accomplished by the gasket between them. The flanges are made of steel and its alloys or of cast iron and other materials. According to the standard, the specifications of the flange should include the following:

5. Brand of manufacturer of flanges

3- Nominal size of pipe (outer diameter of pipe where flange will be welded)

The amount of pressure tolerated by the flange (also called the flange class)

Flange surface shape (flange surface shape is the most important part of a flange)

Holes (sometimes also referred to as wall thickness)

Flange Ingredients (According to ASTM, this number represents the specifications of the raw materials used to make the flange).

Number or code related to heat treatment on flanges Class flanges Flanges are subdivided into different classes depending on the type of pressure-tolerant material:

1- Pressure rating according to ANSI B16.34 According to this standard, steel flanges and their alloys are classified into grades 0-9-6-6-6-6-9 which are the maximum pressure numbers in terms of PSI where the flanges are at maximum The permissible temperature can be tolerated and the operating pressure is usually about 1.5 times the above figures (the relationship of pressure to temperature for the different generations is specified in the standard above).

2- Pressure rating according to ISO standard in this standard bearing pressure of steel flanges and alloys
