Product details

3 PE anticorrosive bend pipe is suitable for the coal mine underground drainage, shotcrete, is negative pressure ventilation, drainage, gas, fire sprinkler pipe network, such as high-rise buildings water supply, heat supply network heating, water engineering, gas supply, such as underground water pipeline. Oil pipelines, chemical pharmaceutical, printing and dyeing industries of process piping for the transmission of corrosive media, sewage discharge pipe, sewage pipe and biological pond anti-corrosion engineering, agricultural irrigation pipe, deep well pipe and drainage pipe network and so on.

3 PE is refers to the three layer PE anticorrosive coating, effective corrosion, 3 PE anticorrosive bend is according to the parent metal cutting costs and simmer bending processing fee, plus the cost of 3 PE anticorrosive, after each type of price range, anti-corrosion are charging per square meter, simmer bending is according to the bending radius and the ratio to determine the price, for the purpose of the 3 PE anticorrosive bend a lot of people are just a man who knows one second, the effect is really coverage is very wide, it is applicable to the coal mine underground water supply and drainage, shotcrete, positive negative pressure ventilation, drainage, gas, such as fire sprinkler pipe network. Waste residue of heat power plant process and water return pipeline. The water supply pipeline of spray and sprinkler system has excellent applicability. Power, communication, highway and other cable protection sleeve. It is suitable for water supply, heat network heating, running water project, gas conveying and underground water transmission. Oil pipeline, chemical pharmaceutical, printing and dyeing industries conveying corrosive media technology pipeline. Sewage treatment discharge pipe, sewage pipe and biological pool anti-corrosion engineering. Agricultural irrigation pipes, deep Wells, drains, etc.
