Job Description:

• 1) Installs and inspects rectifier stations and anodes used to minimize corrosive effects of static-electricity discharge between gas pipeline and ground: Measures electric current present in ground, using voltmeter, ammeter, and resistivity meter.

• 2) Compares electrical quantities with written standard to identify ground areas in which electric current exceeds permissible maximum.

• 3) Buries rectifier or anode near pipe.

• 4) Welds connector to pipe, using thermite welding device, and connects wire between connector and anode to complete circuit.

• 5) Installs insulating flanges at pipe joints to isolate sections of pipe protected by rectifier stations.

• 6) Periodically tests rectifiers to verify efficiency and replaces defective units.
