Test Piles Purpose: Primarily used for detecting cathodic protection parameters, an indispensable device in pipeline management and maintenance, and are arranged along the pipeline based on 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 mainly two 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 ---------------|----------|--------- Standard Test Pile | Φ114 | 1.5 meters - 3 meters Waterproof Test Pile | Φ114 | 1.5 meters - 3 meters Classification of Test Piles: 1. Material-based: Steel test piles, concrete test piles, plastic test piles. Steel test piles are further divided into carbon steel test piles and stainless steel test piles. 2. Function-based: - 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 within the pipeline - Protective Effectiveness Test Pile: Connects test strips We can produce products of different shapes and specifications according to customer requirements.
