ESTRUCTURA DE CONEXION EN FUNDICION O FORJA DE PASOS MULTIPLES PARA LA CONEXION DE UN SISTEMA DE CONDUCCIONES DE CALDERA.

摘要

A multi-pass cast and forged connection structure for boiler pipe system connection, comprising a group of vertical pipes and a group of oblique pipes used for connecting a boiler vertical pipe system. The group of vertical pipes contains a plurality of vertical pipes, all the vertical pipes are in the same plane, and the two ends of each vertical pipe are vertical upward pipe openings (21, 23, 25) and vertical downward pipe openings (22, 24, 26) respectively; the group of oblique pipes contains a plurality of oblique pipes, all of the oblique pipes are in the same plane, and the two ends of each oblique pipe are oblique upward pipe openings (27, 29) and oblique downward pipe openings (20, 28) respectively; and a plurality of vertical pipes and a number of oblique pipes are set at intervals. The connection structure is able to avoid a large number of space jumping pipes and is helpful for hermetically sealing the boiler furnace, reduce stress and differential expansion caused by system expansion, and improve assembly efficiency.
