Jiangsu PPH Coated Flange Manufacturer _ Supplier _ Bulk Sales [Zhenjiang Xingyang Electrical Pipe Industry Co., Ltd.]

PPH Pipe Flanges, also known as PPH Pipe Flange Discs or Rims, are components used to connect pipes to each other and to valves, fitting at the pipe ends. PPH Pipe Flanges feature holes, with bolts securing two PPH Pipe Flanges together. They are sealed with gaskets between the flanges. PPH Pipe Flanges are available in threaded (screwed) connections,焊接 (welded) PPH Pipe Flanges, and sleeve PPH Pipe Flanges.

Container PPH pipe flanges and pipe PPH flanges are divided according to the connected components; by structural type, they are available in integral PPH flanges, slip-on PPH flanges, and threaded PPH flanges. Common integral PPH flanges include flat weld PPH flanges and socket weld PPH flanges. Flat weld PPH flanges have lower rigidity and are suitable for pressures of p≤4MPa. Socket weld PPH flanges, also known as high-neck PPH flanges, have greater rigidity and are suitable for higher pressure and temperature conditions. There are three types of PPH flange sealing surfaces: flat sealing surface, suitable for low-pressure, non-toxic medium conditions; concave-convex sealing surface, suitable for slightly higher pressure conditions; and tongue-and-groove sealing surface, suitable for flammable, explosive, toxic media, and higher pressure conditions.
