Product Details

Our company uses the seamless rolling ring process, which makes the product more stable and can greatly reduce the weight of blanking and save cost. Forged flanges can be made of a wide range of materials including but not limited to 4140, 4130, 35CrMo, 20CrMnMO and can be forged and machined in a wide range of sizes and sizes ranging from 200mm to 3000mm in diameter.

All of our forgings can be forged by hot-die forging, rough working, heat treatment and other processes, increasing the forging ratio and performance stability. Flange forgings can be further processed to achieve final assembly conditions.

Flange dimensions and common precautions

In addition to the functional design of the flange, its size is the most likely factor to affect the flange selection when designing, maintaining and updating the piping system. The interface between flange and pipe and the gasket used must be considered to ensure the correct size. In addition, some common considerations are as follows:

• Outer diameter: the outer diameter refers to the distance between two opposite edges of the flange surface.

• Thickness: The thickness is measured from the outside of the rim.

• Bolt circle diameter: it refers to the distance between relative bolt holes measured from center to center.

• Pipe size: The pipe size refers to the size corresponding to the flange.

• Nominal diameter: The nominal diameter is the size of the inner diameter of the flange connector.
