高圧導管のための接続フランジ

摘要

The invention provides a connection flange for a high pressure conduit and a method for manufacturing same. The flange (60) used for connecting a pipe (80) to another entity (150) comprises a flange body (60) having a proximal (62) and an opposite distal (63), wherein the proximal (62) is attached to the other entity (150). The size and shape of the central hole (70) of the flange body (61) are configured to receive and support the end portion (81) of an inner tube (80). The inner tube (80) is fixedly connected to the flange (60), and the central hole (70) is open to the proximal (62) and the distal (63). At least one solder groove (71) is disposed in the central hole (70) at a portion (71 ') where the diameter is increased. The solder groove (71) opens to the proximal (62) and is so constructed to provide space for the welds between the end portion (81) of the pipe (80) and the flange (60.
