The flange prssure levels are also different
The common flange is used in different places, so the pressure level is a certain difference to a certain extent, such as large stainless steel flange is mainly used in chemical engineering high temperature resistant pipeline in chemical engineering, so its material pressure performance has high requirements. Therefore, customers often require the forging flange, because the material after forging enhances the tissue density, and also enhances its pressure-bearing capacity. In the domestic and international standards for large stainless steel flange compression resistance has a clear grade requirements, large stainless steel flanges are generally divided into: PN25, PN6, PN10, PN16, PN25, PN40 and so on. Two of the commonly used ones are PN10 and PN16. Fange (Flange), also known as flange flange disc or flange. Flanges are the parts connected between shaft and shaft for connection between pipe ends; also for flanges at the inlet and outlet of equipment for connection between two devices, such as reducer flanges. Flange connection or flange joint. It refers to the flanges, gasers and bolts as a group of combined sealing structures. The pressure level of the flange is related to the design pressure, but it is not equivalent. It represents an intensity series of flanges. The greater the pressure level, the stronger it is. To be precise, given the material, design temperature and design pressure, we can select a class of pipelines in a process device as a pressure level according to the temperature and pressure curve on the flange standard, and thus determine the pressure level of valves and other pipe fittings. According to the different flange standard system, it can be divided into European system and American system, such as PN1.6, PN2.5 or CL150 / PN2.0. When hot, some criteria put the two together. The flange is used in different places, so the pressure level is different to a certain extent, such as large stainless steel flange is mainly used in high temperature resistant pipelines in chemical engineering, so its material pressure performance has high requirements. Therefore, customers often require forging flange because the material increases the tissue density.
