About high-pressure flange this problem has been a topic of concern, it is related to the company and enterprise production costs or economic efficiency and other issues, so about high-pressure flange sealing principle in continuous improvement and perfection.
However, the main design drawback of the high-pressure flange is that it is not guaranteed to be leak-free. This is the lack of its design: the connection is dynamic, and such as thermal expansion and fluctuating periodic loads will cause movement between the flange, the flange of the impact function, so that the integrity of the flange damage, eventually leading to leakage. Any product cannot be without defects, but try to control the product to a minimum, so the company in the production of high-pressure flange try to improve the performance of the product, so that it plays the greatest role.
features of high-pressure flange：
Secondly, the flange gasket has been replaced by the sealing ring to ensure that the sealing face of the sealing surface matching. As a result, in order to compress the sealing surface requires only a small pressure. With the reduction of the required pressure, the size and the required number of bolts can be reduced accordingly, so the final design of small size and light weight (70% to 80% lighter than the traditional flange weight) of the new product.
Therefore, high-pressure flange relatively high-quality flange products, reducing the quality and space, played an important role in industrial applications.
