The difference between 3PE and 2PE
3PE: Three-layer PE anti-corrosion layout for pipelines: one layer of epoxy powder (FBE> 100um), the second layer of adhesive (AD) 170-250um, and the third layer of polyethylene (PE) 2.5-3.7mm. The three materials are integrated into one and are firmly connected with the steel pipe to form an excellent anti-corrosion layer. Diameter scale Φ25 ～ Φ2420
2PE: two-layer PE anti-corrosion layout of the pipeline, one layer of adhesive (AD), second layer of polyethylene (PE), the two materials are integrated, and the thickness of each layer is the same as that of the three layers of PE.
3PE anti-corrosion (three-layer polyethylene) process is a leading anti-corrosion technology introduced from abroad in the late 1990s. Its full name is fused epoxy / extruded polyethylene layout protective layer. 3PE anti-corrosion technology summarizes the excellent functions of epoxy coating and kneaded polyethylene two anti-corrosion layers, and links the interface characteristics and chemical resistance of epoxy coating with the mechanical maintenance characteristics of kneaded polyene anti-corrosion layer Then significantly improved their respective functions. Its characteristics: high mechanical strength, wear resistance, corrosion resistance, heat resistance, cold resistance, can be used in 150 degrees medium, are used to in cold areas. Therefore, the 3PE anti-corrosion layer is the outer protective layer of the buried pipeline. According to the inspection of authoritative departments, the life span of buried pipelines with 3PE anticorrosive skills can be as long as 50 years.
2PE anti-corrosion (two-layer polyethylene) pipeline two-layer PE anti-corrosion layout, one layer of adhesive (AD), second layer of polyethylene (PE), the two materials are integrated, and the thickness of each layer is the same as that of three layers of PE.
It can be seen that the difference is that 3PE has an additional epoxy powder layer, and the epoxy powder has good corrosion resistance, good mechanical properties, and strong resistance to cathodic peeling. Although it has the advantages of severe appearance treatment, poor weather resistance, and high water absorption However, it is suitable for buried pipelines and subsea pipelines. The thickness of the cladding layer is only 0.3 to 0.5 mm, and the service life can reach 40 to 50 years.
