Insulator for separating sections of underground metal gas pipe - prevents corrosion due to currents from household appliancesThe insulator has an inner insulating piece (3) connecting the two screw connectors (1,2) of the two sections of pipe being joined. An outer insulating piece (4) enclose...
Any number of factors may cause a small amount of electrical current to flow through the soil and onto the pipe. When electric current discharges into the soil, metal is removed from the surface of the pipe and the corrosion process begins. To protect these underground metal surfaces, cathodic...
The traditional metal pipe generally needs complicated preservative treatment before laying the underground pipes. Even in neutraland non-corrosion soil, the average life of traditional metal pipe is only 10 years. PE flexible pipeline, with PE100 as its outerlay...
