2PE/3PE anticorrosive steel pipe

Specification: Ф89mm-Ф3200mm

Material: Q235B, Q345B, 10# steel, 20# steel, X42-X80 grade

Standard: GB/T23257-2017

2PE/3PE anti-corrosion structure:

The surface of the steel pipe is electrostatically sprayed with epoxy powder, and the adhesive is wound laterally, and the polyethylene anticorrosive layer is wound laterally. Combining the excellent performance of the three, the overall quality of the anticorrosive pipeline is significantly improved. It is resistant to chemical corrosion, cathodic disbondment and mechanical damage.

Before the base material of 2PE/3PE anticorrosive steel pipe is subjected to anticorrosion treatment, it is necessary to inspect and record the steel pipe entering the pipe inlet platform, perform shot blasting to remove rust on the outer surface of the steel pipe, and then check whether the cleanliness and anchor depth of the outer surface of the steel pipe are consistent Requirements, if it does not meet the requirements, it is qualified by hand-grinding and repairing. Wrap tape on the end of the pipe, treat it with fine dust, heat it to the required temperature at medium frequency, spray epoxy powder, wind on the side of the adhesive extruder, and wind on the side of the PE extruder. Water cooling of the anticorrosive pipes, spray marking of qualified products, and the down-pipe platform and stacking are to be shipped.

The 3PE anticorrosive steel pipe has a wide range of applications, and it is suitable for underground coal mine water supply and drainage, underground spraying, positive and negative pressure ventilation, gas drainage, fire sprinkler and other pipe networks. Process water waste residue and return water conveying pipeline in thermal power plant. It has excellent applicability to the water supply pipeline of anti-sprinkling and sprinkling system. Cable protection sleeves for power, communications, highways, etc. It is suitable for high-rise building water supply, heating network heating, tap water engineering, gas transportation, buried water transportation and other pipelines. Process pipelines for transporting corrosive media in industries such as petroleum pipelines, chemical pharmacy, printing and dyeing industries. Sewage treatment discharge pipes, sewage pipes and biological pond anticorrosion projects. For agricultural irrigation pipes, deep well pipes, drainage pipes and other networks, it can be said that 3PE anticorrosive steel pipes are indispensable in the current construction, and it is believed that through the extension of science and technology, it will have more brilliant achievements in the future.
