Test Piles Purpose: Primarily used for the detection of cathodic protection parameters, an indispensable device in pipeline management and maintenance, and are installed along the pipeline according to testing functions. Test piles can be used for testing pipeline potential, current, and insulation performance, as well as for leak detection of the coating and testing of AC/DC interference. Steel Pipe Test Piles Description of Steel Pipe Test Piles: Our company produces two main types of steel pipe test piles: standard steel pipe test piles and waterproof steel pipe test piles. Common sizes are as follows: - Test Pile Type: Diameter, Length - Steel Pipe Test Pile: Φ 114, 1.5 meters to 3 meters - Waterproof Test Pile: Φ 114, 1.5 meters to 3 meters Classification of Test Piles: 1. By material: Steel test piles, cement test piles, plastic test piles. Steel test piles are further divided into carbon steel test piles and stainless steel test piles. 2. By function: - Potential Test Pile: Mainly used for detecting protective potential - Sacrificial Anode Test Pile: Used for connecting sacrificial anodes and measuring their performance parameters - Current Test Pile: Measures current in the pipe - Protection Effectiveness Test Pile: Connects test sheets Custom shapes and specifications can be produced according to customer requirements.
