What Are the Main Causes of ASME Flange Deformation?

Understanding ASME flanges

In industrial production, there is a type of product that must be used and has two characteristics: it is used in pairs rather than individually, and it can be combined with bolts and gaskets to form a detachable joint to connect pipes or equipment. This type of product is called a ASME flange. We all know that there are many ways to classify and types of ASME flanges, but no matter what type of ASME flange it is, deformation is likely to occur during actual use. What causes ASME flange deformation? How can we prevent or reduce ASME flange deformation?

The main reasons for ASME flange deformation

ASME flange material

We all know that there are many materials that can be used to produce ASME flanges, such as carbon steel, low-alloy steel, and stainless steel. Especially for the former (carbon steel), the raw material of carbon steel ASME flanges itself is very soft, which is widely recognized. If the size of a large ASME flange is even larger, it is easy to deform during ASME flange use.

ASME Flange production

Due to the different actual use situation of ASME flanges, customers have different requirements for ASME flange production. Some customers require thinner ASME flanges, while others require thicker ones. In the process of producing large-diameter ASME flanges, deformation problems usually do not occur during forming or at the lathe. However, if the ASME flange is too thin, it is easily affected by heavy objects, pipelines, and its own weight to deform during use.

ASME flange packaging and transportation

There are mainly four types of ASME flange packaging: strapping packaging, pallet packaging, bolt packaging, and ASME flange box packaging. Flanges should be protected with wooden blocks, straw, or plastic foam during transportation, and the binding should be firm. Especially for non-metallic ASME flanges, they should be prevented from mechanical damage and deformation to avoid affecting the sealing effect of the ASME flanges.

ASME flange use

ASME Flanges are usually used in pipeline systems and come into contact with the medium. If the medium temperature is high or highly corrosive, some scale will be deposited on the ASME flange, which will corrode the ASME flange and cause deformation.

Now that we understand the causes of ASME flange deformation, we naturally know how to prevent or reduce ASME flange deformation. We need to take measures from four aspects: ASME flange material, ASME flange production, ASME flange packaging and transportation, and ASME flange use. For example, galvanizing the ASME flange surface can form a special metallurgical structure on the ASME flange surface, which can protect the ASME flange comprehensively even if it is mechanically damaged during transportation and use, such as at dents, sharp corners, and hidden places.
