PRODUCT DESCRIPTION
3PE/3LPE Anti-Corrosion Seamless Steel Tube is a kind of 3pe anti-corrosion steel pipes.
The base material of 3pe anti-corrosion steel pipe includes seamless steel pipe, spiral welded steel pipes and straight seam welded steel pipe. The three-layer polyethylene (3PE) anti-corrosion coating has been widely used in the oil pipeline industry due to its good corrosion resistance, water vapor permeability resistance and mechanical properties.
3PE anti-corrosion steel pipes refers to 3-layer structure polyethylene coating (MAPEC) outer anti-corrosion steel tube. Other anti-corrosion methods include IPN8710, FBE epoxy powder, and epoxy coal tar pitch. Generally refers to the anti-corrosion of the outer wall of the steel pipe.
Anti-corrosion form of steel pipe outer wall
3PE anti-corrosion generally consists of 3 layers of structure:
The first layer of epoxy powder (FBE>100um)
The second layer of adhesive (AD) 170～250um
The third layer of polyethylene (PE) 1.8 ~ 3.7mm
Steel pipe inner wall anticorrosion
There are two types of anti-corrosion for the inner wall of steel pipes: one is hot-melt epoxy resin powder anti-corrosion (high temperature fusion bonding), the other is liquid epoxy coating, and liquid epoxy IPN8710 is commonly used (normal temperature cold spraying)
Product use
Many people only know one of the uses of 3PE anti-corrosion steel pipes. Its role is really wide coverage. It is suitable for underground coal mine water supply and drainage, underground spraying, positive and negative pressure ventilation, gas drainage, fire sprinkler Wait for the pipe network. Thermal power plant process water waste slag and return water pipeline. It has excellent applicability for water supply pipelines of sprinkler and sprinkler systems. Electric power, communication, highway and other cable protection sleeves. Applicable to high-rise building water supply, heating network heating, water supply engineering, gas transmission, buried water transmission and other pipelines. Process pipelines for transporting corrosive media in petroleum pipelines, chemical, pharmaceutical, printing and dyeing industries. Sewage treatment discharge pipes, sewage pipes and bio-pool anti-corrosion projects. It can be said that 3PE anti-corrosion steel pipes are indispensable in the current construction for agricultural irrigation pipes, deep well pipes, drainage pipes and other networks. I believe that through the extension of technology, it will still have more brilliant achievements in the future.
Product production process
3PE anti-corrosion steel tubes base material needs to check and record the steel pipe entering the pipe platform before anti-corrosion treatment, perform shot blasting and rust removal on the outer surface of the steel pipe, and then check whether the cleanliness of the outer surface of the steel pipe and the depth of the anchor pattern meet the requirements. Those that do not meet the requirements shall be ground and repaired by hand with a grinding wheel, wrapped with tape at the end of the pipe, treated with micro-dust, heated to the required temperature with intermediate frequency, sprayed with epoxy powder, wound on the side of the adhesive extruder, wound on the side of the PE extruder, and applied to the anti-corrosion pipe Water cooling is carried out, qualified products are sprayed and marked, and the tube platform is lowered and stacked for shipment.
