Product Detail

It takes a lot of work to create butt welding flanges, and because large butt welding flanges have such high manufacturing costs, preheating is frequently necessary. The deformation of raw materials and the deformation process related to temperature and mechanical characteristics of the mathematical model is known as computer simulation flange. This deformation process is carried out with the aid of a computer simulation at any time when the state of stress, strain, and temperature distribution is present. Computerized physical simulation and process simulation can both support and enhance one another. Butt welding flanges are labor-intensive to make, and preheating is commonly required due to the high expense of making big butt welding flanges. Computer simulation flange is the term used to describe how raw materials deform as well as how the temperature and mechanical properties of the mathematical model deform. A computer simulation is used to perform this deformation process whenever the conditions of stress, strain, and temperature distribution are met. Computerized process simulation and physical simulation can both benefit from and complement one another.

The European pipe flange system, which includes the former Soviet Union, is represented by German DIN, and the American pipe flange system is represented by American ANSI pipe flange. These two standards are the principal ones used internationally. Japanese JIS tube flanges are another option, although their international influence is lessened because they are typically only utilized for public works in petrochemical sites. The following is a basic overview of the pipe flanges used in each nation:
1.Germany and the former Soviet Union are the two members of the European system framework.
2.The ANSI B16.5 and ANSI B 16.47 American system pipe flange standards
3.There are separate casing flange standards for the two countries' respective pipe flanges.
In conclusion, the two distinct and non-interchangeable pipe flange systems that make up the worldwide standard of pipe flanges are as follows: a European pipe flange system, represented by Germany; and an American pipe flange system, represented by the United States.
The International Organization for Standardization published the pipe flange standard known as IOS7005-1 in 1992. This standard combines the pipe flange standards from Germany and the United States.
