3PE coating steel pipe anticorrosion structure: 1 layer of epoxy powder (FBE > 100 um), the second floor adhesive (AD) 170 ~ 250 um, the third layer of polyethylene (PE) 1.8 ~ 3.7 mm. Three kinds of material, and form with steel pipe firmly with excellent anticorrosive coating. Advantages: 1, 3 PE anticorrosive coating steel pipe has a very high sealing, long running can greatly save energy, reduce costs, protect the environment. 2, strong corrosion resistant ability, Jane has the speed, quality service life can reach 30 to 50 years. 3, under the condition of low temperature and has good corrosion resistance and impact resistance, PE bibulous rate is low (less than 0.01%). 4, have a combination of high strength epoxy, PE low water imbibition and hot melt adhesive softness, etc., has a high anticorrosion reliability.
3 PE anticorrosive (three layer PE) technology is introduced from abroad in the late 1990 s advanced anti-corrosion technology, it's called the fusion bonded epoxy/extruded polyethylene protective layer structure. 3 PE anticorrosion technology combines epoxy coating and extruded polyethylene anticorrosive coating of excellent performance, the interface properties of epoxy coating and chemical properties and extruding polyene anticorrosive coating of mechanical protection features etc, so as to significantly improve their performance. Its characteristics: high mechanical strength, wear resistance, corrosion resistance, heat resistance, cold resistance, medium can be applied to 150 degrees, both in cold zone. Therefore, 3 PE coating is the ideal of buried pipeline outer protective layer. According to authoritative department detection, with 3 PE anticorrosive technology of buried structural steel pipe life up to 50 years.
Difference of PSL1 and PSL2(API 5L)
The API 5L has two standards, PSL1 and PSL2, which are very different from each other. I'll talk more about the differences between PSL1 and PSL2.Production Process of Pipe Fitting
There are many kinds of processing methods for pipe fittings.The Future of Steel Pipe Development
The future of steel pipe development is looking promising, according to expert analysis and data. The price of carbon steel pipe is predicted to bounce back this year, with China leading the way in increasing steel consumption demands. This is due to a series of government initiatives aimed at stimulating domestic demand, including the construction of affordable housing and infrastructure projects. The demand for structural steel pipe is also on the rise, thanks to state investment in housing and engineering projects. With private investment projects also gaining popularity, the steel pipe market is set to thrive in 2017.
