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.
Claims6
A method for manufacturing a pipe connector of a gas isolated switchgear (G.I.S.) comprising the steps:
- step 1:
- preparing an aluminum alloy material block;
- step 2:
- first forging the material block to form a first flange on a first end of the material block;
- step 3:
- second forging the material block in step 2 to form a second flange on a second end of the material block to form the material block to an I-shaped member;
- step 4:
- defining a passage through the I-shaped member in step 3;
- step 5:
- stretching the I-shaped member in step 4 to a desired length;
- step 6:
- applying a first heat treatment process (T4 process) to the I-shaped member in step 5;
- step 7:
- straightening the I-shaped member in step 6;
- and
- step 8:
- applying a second heat treatment process (T6 process) to the I-shaped member in step 7.
