　　Product type: explosion-proof junction box

　　Product Introduction:

　　Test pile is also called test pile, according to the material can be divided into steel test pile, cement test pile, plastic steel test pile, carbon steel test pile. According to the use environment,

　　it can be divided into city network test pile, buried pipeline test pile and so on. Mainly used for the detection of cathodic protection parameters, is an essential device in pipeline

　　management and maintenance, according to the test function along the layout. 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.

　　Our company according to customer requirements design anti-theft, explosion-proof test pile and defense multi-functional test pile, using the latest technology surface spray

　　galvanized, effectively prevent the test pile in use itself corrosion. The test pile of our company adopts seamless welding technology, durable, beautiful and elegant,

　　is an ideal choice for the test pile of cathodic protection parameters.

　　Our company's production of steel pipe test pile mainly ordinary steel pipe test pile, rain - proof steel pipe test pile. Common sizes are as follows:

　　Test pile type diameter length

　　Steel tube test pile φ 108 1.5-3m

　　Rain proof test pile φ 108 1.5m - 3m

　　Classification of test pile:

　　1, according to the 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 to detect protection potential

　　● Sacrificial anode test pile: Used to connect the sacrificial anode and measure the performance parameters of the sacrificial anode

　　● Current test pile: measure the current in the tube

　　● Protection effect test pile: connect the test piece

　　According to customer needs to produce different shapes, different specifications of products.
