Abstract
A method for manufacturing a pipe connector for a gas isolated switchgear has the steps of preparing a material block, a first forging process, a second forging process to form the material block to an I-shaped member, defining a passage through the I-shaped member, stretching the I-shaped member, a first heat treatment process (T4 process), straightening the I-shaped member to a desired length and a second heat treatment process (T6 process). With such a method, the processes for manufacturing the pipe connector are simple, and the cost for manufacturing the pipe connector is low.
