  How is the large flange of the core of the production of it?

  Take a common example of the national standard elbow bar, if it is the production of long radius elbow, we need to first select the product specifications, and then put the pipe material, and then calculated according to the calculation of a good expansion rate. After the completion of the basic processing, but also the need for a series of finishing products, that is, the appearance of the product and other details for further processing, which mainly includes shot peening, playing steel, surface spraying and packaging work The Large flanges are common flanges with flattened flanges and DIN 2573 25bar Carbon Steel Forged Slip on Flange. Slip on flange of the poor, suitable for the pressure p ≤ 4MPa occasions; welding flange, also known as high-neck flange, high rigidity, suitable for high pressure temperature occasions. There are three types of flange sealing surface: flat type sealing surface, suitable for the pressure is not high, the media non-toxic occasions; convex sealing surface, for a slightly higher pressure occasions; tongue seal surface, for flammable, explosive , Toxic media and high pressure occasions. Different nature of the flange fittings in different areas with good product performance, to adapt to the occasion and space, the resulting effect will be different.
