Test piles Uses: mainly used to detect cathodic protection parameters, pipeline management is essential to maintain the device, press the test function emplaced along. Pipe pile can be used for testing potential, current, insulation performance of the test, the coating layer may also be used for leak testing and DC interference. Test piles is a specialized pipeline cathodic protection with potential for test probes to test for protective pipe ancillary equipment. Test piles from the inside and outside galvanized pipe, testing lines, test connector components. Detection connector is divided into six, eight, ten three joints can be produced according to user requirements. Model ZHC-3, ZHC-2. Test piles have full-height 3 meters or two meters of two, 0.1 meters in diameter. Recent improvements through the use of test piles outside of the outer coating Charade car paint spraying. Hence better corrosion resistance to ultraviolet aging properties. Test port test piles, door shaft made of stainless steel. Test piles detect mouth rain eaves to prevent water intrusion. Detection test piles door open with a special key to prevent irregular open. Size: 2000 × Φ 108 × 4mm; 1800 × Φ 89 × 3mm; 1200 × 120 × 120mm; Classification 1600 × 500 × 300 test piles: 1, Material: steel test piles, concrete test piles, test piles of plastic . Steel test piles are divided into stainless steel test piles and test piles. 2, by function: ● potential test piles: mainly used to detect potential ● sacrificial anode protection test piles: for connecting a sacrificial anode, sacrificial anode to measure performance parameters ● Current test piles: measuring tube current ● protective effect test piles: Connect the test piece
