External Electrode Sponge for Holiday Detector Models: M-a, M-1/AC

Square cut, tightly wound stainless steel wire, for tight fit and intimate contact to coatings applied to pipelines. Made for use on pipelines, the Full Circle Spring Electrode will inspect the entire coated surface of the pipe in one pass. Available sizes based on pipe O.D. 4” OD to 48” OD, in 2” increments. Inquire about Full Circle Spring.

Electrodes for pipe OD greater than 48” OD.

• Made for Outside Pipe Diameters of 4” through 60”, in 2” increments
• Stainless Steel, square cut construction for intimate contact with pipe coating surface
• Easy to install, wraps around pipe.
• All aluminum couplings include bearings for easy rolling down pipe.

Using the same square cut, tightly wound stainless steel wire that the Full Circle Spring Electrodes use, the Half Circle Spring Electrode will cover more than 180 degrees of pipe circumference and is meant for small diameter pipes, .750” OD to 3” OD), or pipes with fittings, T’s, bends or other inclusions that may hamper the use of a Full Circle Spring Electrode.

• Made for Outside Pipe Diameters of ¾” through 14”
• Stainless Steel, square cut construction for intimate contact with pipe coating surface
• Inspects over 180 degrees of pipe circumference.
• All aluminum couplings include bearings for easy rolling down pipe.

Internal Electrodes are made to order to fit the exact Inside Diameter of your pipe. Internal Electrodes are made for use with High Voltage (Silicone-Rubber material) and Low Voltage (Sponge material) Holiday Detectors. The electrodes fit pipe ID starting at 2” and continuing up to 36” and beyond. Internal leg supports can be added to center and support the electrode to ensure intimate contact between the electrode and the coating. Custom sizes and materials also available.

• Used to inspect coatings inside pipes.
• Available in silicone-rubber for high voltage holiday detectors
• Available in sponge material for low voltage holiday detectors
• Cut to exact inside diameter of pipe, including coating thickness

Internal "Low Voltage" Sponge Electrodes for use with Holiday Detector Models: M-1, M-1/AC.

Made from a unique combination of silicone rubber and carbon, the Silicone-Rubber Brush Electrode meets many different requirements and applications, both on pipe and off. The electrode is used to inspect weld joints on the outside or coatings applied to the inside of pipelines. Also, inside and outside of tanks, rail cars, concrete structures, just about any conductive substrate with a non-conductive coating. The Silicone-Rubber Brush Electrodes are available in 2” to 48” widths in 2” increments.

• Squeegee type brush electrode
• Made of high conductivity silicone-rubber materials.
• Available in widths of 2” through 48” or in sheets.
• Sheet material useful for grounding mats.

Made from a unique combination of silicone rubber and carbon, the Wire Brush Electrode meets many different requirements and applications, especially for coated surfaces that are uneven or include fittings, bolts, or other tight corners need to be inspected. The electrode is used to inspect weld joints on the outside or coatings applied to the inside of pipelines. Also, inside and outside of tanks, rail cars, concrete structures, just about any conductive substrate with a non-conductive coating. The Wire Brush Electrodes are available in 2” to 60” widths in 2” increments.

• Individual Stainless Steel wires make up brush.
• Available in 2” through 48” widths.
• Recommended for use on structures with odd shapes or angles, to keep intimate contact with coating surface.
