Purpose of test pile: It is mainly used for the detection of cathodic protection parameters, and is an essential device in pipeline management and maintenance. It is arranged along the test line according to the test function.
The test pile can be used to test the potential, current and insulation performance of the pipeline, and also can be used to test the leakage of the covering layer and ac/DC interference.
Test pile is a kind of auxiliary equipment specially used for the cathodic protection of pipeline with potential test probe to test the protection pipeline.
The test pile is composed of internal and external galvanized pipe, testing line and testing joint. Testing joints are divided into six, eight, ten joints, can be produced according to user requirements.
The models are ZHC-3 and ZHC-2.
The test pile is 3 meters high or 2 meters high and has a diameter of 0.1 meters.
After the latest improvement test pile outside the use of Xiali automobile outer coating paint spraying. Therefore, it has better anti-corrosion, anti-ultraviolet and anti-aging properties.
The testing port and door shaft of the test pile are made of stainless steel. The test pile is equipped with eaves to prevent rain from invading. The test pile test door is provided with a special key to prevent abnormal opening.
Usage:
The most important application of test pile is to test the cathodic protection potential. It is commonly used to test the cathodic protection potential of underground or underwater metal structures such as storage tanks and pipelines. When in use, one or more zero cables are welded on the protected body as required and introduced into the terminal of the test pile. At the same time, one or more reference electrode cables are also introduced into the terminal of the test pile. The terminals are independent and do not communicate with each other; The test pile can also be used for wiring purposes. When used for wiring purposes, the corresponding terminal is connected with a special connection piece.
Notes:
The installation position of the test pile should be selected in the place where water scour, landslide and debris flow are not easy to occur. The installation should ensure that the foundation is firm to avoid settlement resulting in pile tilt.
