| 3LPP anti-corrosion pipe: It is a new type of anti-corrosion pipeline with unique characteristics in terms of performance and application. The following is a specific introduction:
Structural composition
The structure of 3LPP anti-corrosion pipe is similar to that of 3LPE anti-corrosion pipe, and also adopts a three-layer structure. The bottom layer is also coated with epoxy powder, providing good adhesion and corrosion resistance; The middle layer is a special adhesive; The outer layer is made of polypropylene (PP), which is the main difference from 3LPE anti-corrosion pipes. Polypropylene has higher strength and heat resistance.
Performance characteristics
Excellent mechanical performance: The outer layer of polypropylene has higher hardness, strength, and impact resistance, which can better resist external mechanical damage, especially suitable for harsh construction environments and occasions with high requirements for pipeline mechanical performance.
Good chemical corrosion resistance: It has excellent resistance to various chemical substances and can effectively prevent corrosion of pipelines by corrosive media such as acid, alkali, salt, etc., extending the service life of pipelines.
Outstanding high temperature resistance: Compared with 3LPE anti-corrosion pipes, the polypropylene outer layer of 3LPP anti-corrosion pipes can withstand higher temperatures and generally maintain stable performance in the temperature range of -20 ¡æ to 100 ¡æ or even higher. It is suitable for the transportation of some high-temperature media, such as hot oil, high-temperature steam, etc.
Good anti-aging performance: It has good weather resistance and anti ultraviolet performance. When exposed to the natural environment for a long time, it is not prone to aging, embrittlement and other phenomena, and can maintain good anti-corrosion performance.
application area
3LPP anti-corrosion pipes are commonly used in fields that require high anti-corrosion and mechanical performance of pipelines, such as transportation pipelines for high-temperature, high-pressure, and highly corrosive media in the petroleum and chemical industries, as well as steel pipe anti-corrosion protection in marine engineering and port facilities. In some pipeline systems that require long-term stable operation and harsh environmental conditions, 3LPP anti-corrosion pipes can leverage their advantages to ensure the safe and reliable operation of pipelines. |
