2020-12-20
Natural gas is now widely recognized as a low-carbon, clean energy source worldwide. Its development and application have become pivotal for optimizing the structure of China’s energy utilization and petrochemical industry upgrading. The widespread adoption of natural gas as a clean energy source across various industries has led to a substantial increase in demand for natural gas pipelines, since coated steel pipes not only boast the high strength characteristic of steel pipes but also exhibit superior corrosion resistance.
Natural gas is now widely recognized as a low-carbon, clean energy source worldwide. Its development and application have become pivotal to optimizing the structure of China’s energy utilization and petrochemical industry upgrading. The widespread adoption of natural gas as a clean energy source across various industries has led to a significant increase in demand for natural gas pipelines, because... Plastic-coated steel pipe It not only boasts the high strength characteristic of steel pipes but also exhibits strong corrosion resistance.
Engineering plastic pipes can also be installed using trenchless pulling methods, or even by reclamation techniques and sand-free backfilling methods. These approaches effectively enhance the safety and reliability of pipeline networks. Therefore, coated steel pipes hold great potential for widespread adoption and application in gas fields.
Plastic-coated steel pipes retain the original high strength and toughness of steel pipes while also boasting excellent corrosion resistance, corrosion durability, and crack resistance. Since the epoxy powder coating is applied to the inner wall of the steel pipe, it effectively reduces the intensity of ultraviolet radiation and exhibits outstanding aging resistance. The epoxy resin powder layer effectively prevents the steel pipe from being corroded by corrosive components in gases, significantly extending the service life of the pipe.
Plastic-coated steel pipes can be used indoors and outdoors, on the ground and underground, in both northern and southern regions, and even buried in elevated structures. They operate within a temperature range of -40°C to 95°C. Their installation and usage methods are similar to those of conventional galvanized pipes—simple, time-saving, and safe and reliable.
Plastic-coated steel pipe Its sensing performance is significantly superior to that of PE pipes, cast-iron pipes, and aluminum-plastic pipes. Although traditional copper and stainless steel pipes offer even better performance, they require special connection methods during installation, which are technically challenging and costly. Moreover, these pipes are also very expensive, and copper pipes tend to develop a green patina on their surface relatively easily.
