Test pile purposes: mainly used for the detection of the cathodic protection parameters, device is essential in the management and maintenance of pipeline laid along the test function. Test piles for pipeline potential, current, insulation performance test can also be used to overlay Leak and AC-DC interference test steel pipe test piles pipe test piles Description: Our company produces steel test piles ordinary steel test piles, the weatherproof steel pipe test piles. Common dimensions are as follows: the type of test piles diameter length of steel pipe test pile of Φ 114 1.5 meters - 3 meters rain test piles Φ 114 1.5 meters - 3 m test pile classification: 1, Material: steel test piles, the cement test piles, plastic test pile. Steel test piles are divided into carbon steel test piles and stainless steel test piles. 2, by function: ● potential test piles: mainly used to detect the protection potential ● sacrificial anode test piles: used to connect the sacrificial anode to measure the performance parameters of the sacrificial anode ● current test piles: measuring tube current ● protective effect of test piles: Connect the test piece
