Abstract

PURPOSE: To manufacture a casing that is high in reliability and low in cost in such a way that welding is done in the field for just inlet port of a casing, longitudinal divided part at the last volute part, and its appendant circular joint parts, whereas the other divided parts are assembled by connecting with flanges.
CONSTITUTION: Inlet port of a casing 1, longitudinal joint part of the divided part at the last volute part, and its appendant circular joint parts are respectively connected with joints 1c for welding in the field. And other circular joint parts are connected with circular joint flanges 1a. Thus, since welding in the field is minimized by both using welding connection in the field and flange connection, the longitudinal joint flanges can be highly reliable welding joints.
