Also, test stand is made of an iron pipe with a diameter of 75, 100 or 150 mm according to request. Shadow is made from iron sheet with thickness of 2 or 3 mm.

 

 

different Segments and parts of bornagodaz testpoint are as follows:

*  1, 2 or 4 brass terminals (suitable brass screws and nuts) are installed inside the test point as request.

*  three iron bars are placed on the base bottom as a tent in order to install inside the Concrete structures.

*  a suitable hole is provided at the bottom of iron pipe base for convenient entrance and exit of cable.

• Marker

This equipment as a cathodic protection accessory is used for indicating pipeline scanning, initial and final locations of cathodic protection bed. The marker base is made of an iron pipe with 75, 100 or 150 mm diameter as request. A canopy is made iron sheet with 2 or 3 mm thickness in order to prevent degradation of paint due to sunlight and corrosion problems.

BORNA Godaz company can use following methods as coating or painting of bond box, testpoint and markers:

*  Hot galvanized

*  Special furnace colors with a phosphate or chromate coating.

*  Special epoxy or alkyd colors with sandblast coating.
