3PE Anti-corrosion Steel Pipe Has High Quality Anti-corrosion Ability

PE is a kind of material for anti-corrosion steel pipe. This material is called polyethylene, so PE anti-corrosion steel pipe can also be called polyethylene anti-corrosion steel pipe.

3PE anti-corrosion steel pipe and 2PE anti-corrosion steel pipe are two classifications of PE anti-corrosion steel pipe. I believe that some friends will ask at this time, why is 3PE anti-corrosion steel pipe more favored by people? Let us analyze it below:

In terms of structure, 3pe anti-corrosion steel pipe refers to 3-layer structure polyolefin coating (MAPEC) outer anti-corrosion steel pipe, generally used for electric resistance welded pipe, first layer epoxy powder (FBE>100um), second layer adhesive (AD)170 ~250um, the third layer of polyethylene (PE) 2.5 ~ 3.7mm, the actual operation of the three materials mixed into one, after processing to firmly bond with the steel pipe to form an excellent anti-corrosion layer; and 2PE anti-corrosion (two-layer polyethylene Pipeline two-layer PE anti-corrosion structure, the first layer of adhesive (AD), the second layer of polyethylene (PE), the two materials are integrated.

In terms of price performance, the service life of 3pe anti-corrosion steel pipe is 3-5 times longer than other steel pipes, so the price of 3PE anti-corrosion is higher than that of other steel pipes.

In recent years, due to the sustainable development of the global economy, the rapid increase in demand for energy has also promoted the development of oil and gas pipeline transportation.

Long-distance, large-caliber, cross-border international oil and gas pipelines have been built. Although oil and natural gas are generally collected after oil and gas field collection, they are subjected to purification treatment such as dehydration and desulfurization. In particular, the oil and gas quality control of the main trunk line is strict.

However, in the process of oil and gas storage and transportation, the environment is very different and the working conditions are complex and varied. Corrosion of the inner wall of the pipeline is caused to a certain extent, so the anti-corrosion engineering is a key point that cannot be ignored.

Long-term practice has proved that 3PE anti-corrosion steel pipe has high-quality anti-corrosion ability. Anti-corrosion coating used for anti-corrosion is an economical and effective anti-corrosion measure.

In recent years, 3PE anti-corrosion steel pipes and reinforced grade 3PE anti-corrosion steel pipes have been applied to large-scale pipeline projects. The beginning of each large medium-range is the peak season for the sale of 3PE anti-corrosion steel pipes.

Finally, we can conclude that the 3PE anti-corrosion steel pipe has an epoxy powder layer, and the epoxy powder has good corrosion resistance, good mechanical properties and strong anti-cathode peeling, although it has strict surface treatment, poor weather resistance, high water absorption rate, etc.

Advantages, but it is suitable for buried pipeline submarine pipelines, the thickness of the cladding is only 0.3 ~ 0.5 mm, and the service life can reach 40 to 50 years.
