This product is mainly used in pipeline cathodic corrosion protection of oil, natural gas, hydrocarbons, water, steam and corrosive liquids and other media. According to user requirements using different tube materials, such as: high strength carbon steel, stainless steel, double joints; also use a different mix of pipe connections, such as: carbon steel and stainless steel, steel and copper, steel and titanium. Finished overall pipeline terminal insulation joints have been processed in the factory, there are multiple connectivity options to choose from: eg flanged, threaded connections, threaded connections and welded connections with valves. Features Good (1) Insulation: Insulation resistance 10MΩ, improve protected pipeline operating life. (2) Long life: with the pipeline with life, such as strength; (3) high strength: The secondary containment structure, coupled with the annular space between the two flanges injected polymer composites, to the life and pipelines over insulation Flange life expectancy has increased many times over; (4) underground installation: do not set up observation wells installed underground, direct buried; the company's main products are: ☆ magnesium alloy sacrificial anode series: magnesium manganese alloy sacrificial anodes, bracelet style magnesium alloy sacrificial anode, magnesium alloy semi-continuous casting rod, aluminum magnesium alloy sheet ☆ sacrificial anode series: ordinary aluminum sacrificial anodes, efficient aluminum sacrificial anodes, high-activated aluminum bracelet sacrificial anode aluminum alloy zinc alloy sacrificial anodes ☆ sacrificial anode Series: Marine zinc alloy sacrificial anodes ☆ complementary products: the reference electrode, test piles, fill and materials, long-term reference electrode, portable reference electrode, test piles ordinary cement test piles ☆ impressed current cathodic protection: high silicon cast iron anode, deep anode, sacrificial anode, magnesium alloy sacrificial anode, the sacrificial anode aluminum, zinc alloy sacrificial anode, magnesium ribbon, zinc ribbon, the reference electrode, test piles, magnesium alloy rods, zinc grounding the battery, second-generation anti-theft rain test piles, insulation joints, and cathodic protection auxiliary materials, long-term participation of high silicon cast iron anode electrodes and impressed current use, potentiostat and other products.
