There are two main international pipe flange standards: the European pipe flange system represented by German DIN (including the former Soviet Union) and the American pipe flange system represented by American ANSI pipe flange. German standards are relatively the most stringent, but for the vast majority of European customers, they do not need to purchase German standard flanges for general environment, but EN stainless steel thread flange flanges. The main purchasing places of EU countries are Italy and China. China is relatively more experienced, so our export of EN stainless steel thread flange ranks first in the world.

The EN stainless steel thread flange is connected with the pipe wall through the thread, and the additional pressure on the pipe wall is small. It is one of the flange structures widely used in engineering construction. It has the advantages of convenient installation on site and no welding. The sealing surface type has convex surface and plane.
