What determines the machining accuracy of Blind Flanges?

Blind Flanges is widely used in natural gas, petroleum engineering, water treatment engineering and other projects requiring pipeline connection. This kind of project requiring Blind Flanges is generally a major project involving people's livelihood no matter where it is used in the world, with large distance and strong professionalism, which determines that the precision of Blind Flanges required is also very high, which is responsible for affecting the quality and safety index of the project. The machining accuracy of Blind Flanges is mainly used to indicate the fineness of Blind Flanges and to evaluate the machining surface of Blind Flanges. The machining accuracy of Blind Flanges is generally expressed by tolerance. The tolerance represents the accuracy. The smaller the tolerance, the higher the accuracy of Blind Flanges. The tolerance of Blind Flanges of general engineering parts is divided into 20 grades. The highest grade is generally used in aerospace engineering, or offshore oil and gas engineering. The Blind Flanges with the highest tolerance grade is generally used for agricultural machinery and is not suitable for engineering. The pressure range of Blind Flanges is different from the standard of Blind Flanges according to the use scene (such as ASME B16.5, DIN2425, en1092-1, etc.), which determines that the tolerance range of Blind Flanges is different, and then determines that the processing accuracy of Blind Flanges is different, and the specific requirements of processing such as heat treatment method are also different.Shanxi Haokun Flanges Group Co., Ltd. has focused on the production of various standard Blind Flanges for more than 20 years, and its mastery of tolerance is very high in the industry. Blind Flanges purchasers can also explain their processing accuracy and tolerance requirements in the technical requirements of the order when placing an order according to their own requirements.
