3LPE is a coating used for anti-corrosion of steel pipes.making the pipes more durable.The outer anti-corrosion layer of the long-distance oil and gas pipeline is an important barrier to ensure the safety of the pipeline. Due to the increasing demand for energy in emerging economies such as China and India, the world's pipeline construction has entered a new round of climax, thereby promoting the development of anti-corrosive coating technology for long-distance pipelines.

At present, commonly used anti-corrosive coatings for pipes outside the world include: petroleum asphalt (AE), coal tar enamel (CTE), fused epoxy powder (FBE), three-layer polyethylene coating (3LPE), and three-layer polypropylene Coating (3LPP), etc.

From the perspective of development trends, 3LPE has occupied an advantage in the international pipeline coating market competition, and its market share will continue to expand.

As the outer anti-corrosion coating for pipes, 3LPE anti-corrosion coating has a minimum thickness requirement, so the application cost is high. At the same time, the failure of its joints also affects the safe operation of the pipeline.

Therefore, in recent years, in view of the new problems encountered in the use of pipeline coatings, coating manufacturers in various countries have either improved their materials on the basis of traditional FBE and 3LPE or developed new coatings. The results, and gradually applied to production. Xinyue has also been working hard for this, within this year we has completed several international projects with strict requirements on coatings.

3PE anti-corrosion steel pipe is the leader in the anti-corrosion steel pipe industry. No matter in performance or product appearance, 3PE anti-corrosion steel pipe surpasses other anti-corrosion. However, 3PE anti-corrosion steel pipe also has disadvantages. It’s good, but low hardness. Therefore, the anti-corrosion layer is easy to be damaged during handling, transportation and hoisting . Once the anti-corrosion layer is damaged, it will directly affect the anti-corrosion effect of 3PE anti-corrosion steel pipe and lifespan.

Xinyue has rich operating experience in 3PE pipeline transportation, which has protected the integrity of the pipeline coating to the greatest extent.During the handling process, we use steel hooks to lift both ends of the pipes, and try not to touch the anti-corrosion coating . This is one way to ensure that the 3PE anti-corrosion steel pipe does not fall off.In addition, after the production and inspection of 3PE anti-corrosion steel pipes, a relatively thick fiber rope will be tied at both ends of the steel pipe, so that the 3PE anti-corrosion steel pipes can be separated from each other during storage and transportation to avoid being hard bumping.

Anti-corrosion pipelines are only a small part of Xinyue's business in construction of the world. We will always provide you with our professional and on-time service on pipeline and technical support in any time !
