Yangzhong PPH Coated Flange Price, Wholesale, Sales, Best Supplier - Zhenjiang Xingyang Electrical Pipe Industry Co., Ltd.

PPH pipe flanges, also known as PPH pipe flange discs or raised rings, are components used to connect pipes to each other and to valves, attaching at the pipe ends. PPH pipe flanges feature holes, and bolts are used to securely fasten two PPH pipe flanges together. Gaskets are used to seal the joints between PPH pipe flanges. They are available in threaded (screwed) PPH pipe flanges, welded PPH pipe flanges, and sleeve PPH pipe flanges.

Container PPH flanges and pipe PPH flanges are divided according to the connected components; structurally, they are available in integral PPH flanges, loose fit PPH flanges, and threaded PPH flanges. Common integral PPH flanges include flat welding PPH flanges and socket welding PPH flanges. Flat welding PPH flanges have lower rigidity and are suitable for pressures p≤4MPa. Socket welding 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 tenon-slot sealing surface, suitable for flammable, explosive, toxic media, and higher pressure conditions.
