　　Product type: test pile

　　Main performance: rain proof, anti-theft, strong, durable, beautiful.

　　Scope of application: It is used to measure the corrosion protection potential, current, insulation performance and other important parameters of the main distribution

　　points of the cathodic protection system.

　　Detailed introduction:

　　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. Mainly used for cathodic

　　protection & GT; The detection of cathodic protection parameters is an essential device in pipeline management and maintenance. 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.

　　Classification of test pile:

　　1. According to material:

　　Steel test pile, cement test pile, plastic test pile. Steel test pile is divided into carbon steel test pile and stainless steel test pile.

　　2. According to functions:

　　Potential test pile: mainly used for detecting protection potential;

　　Sacrificial anode test pile: used to connect the sacrificial anode and measure the performance parameters of the sacrificial anode;

　　Current testing pile: measuring the current in the tube;

　　Protection effect test pile: connect the test piece.

　　According to the needs of the market, our company independently developed and produced the second generation of rainproof test pile, inherited the previous generation

　　of excellent design concept, the door shaft is made of stainless steel. Test pile detection mouth with rain eaves, prevent rain intrusion; The test pile test door is provided with

　　a special key to prevent abnormal opening. At the same time, it also has the advantages of anti-theft, strong, durable and beautiful. It is suitable for cathodic protection of

　　buried metal pipelines in different industries such as natural gas, liquefied petroleum gas, petroleum, refined oil, artificial gas, chemical industry, water conservancy and tap water.

　　Cathodic protection of urban underground structures (such as buried metal pipe network, oil field pipe network and long distance buried metal pipeline) & GT; Cathodic protection

　　is also applicable.

　　Can be customized according to customer requirements of special specifications of the test pile.
