Anti-corrosion spiral steel pipe plays an important and different role in people's daily life. Anti-corrosion spiral steel pipe generally refers to the use of special technology to treat ordinary spiral steel pipe with anti-corrosion treatment, so that the spiral steel pipe has a certain anti-corrosion ability. Generally, it is used for waterproofing, anti-rust, anti-acid, and alkali, and anti-oxidation.


Spiral steel pipes are often used for fluid transportation and gas transportation, and pipelines often need to be buried, launched, or overhead construction. The corrosion-prone characteristics of steel pipes and the construction application environment of pipes determine the construction of spiral steel pipes. If the construction is not in place, it will not only affect the service life of the pipes, but even cause catastrophic accidents such as environmental pollution, fire, and explosion.


At present, almost all spiral steel pipe application projects will carry out anti-corrosion technology treatment on the pipeline to ensure the service life of the spiral steel pipe and the safety and environmental protection of the pipeline project. The anti-corrosion performance of the spiral steel pipe will also affect the economy of the pipeline project. maintenance costs.


The anti-corrosion process of spiral steel pipes has formed a very mature anti-corrosion system according to different uses and anti-corrosion processes.


IPN8710 anti-corrosion and epoxy coal tar anti-corrosion are mainly used in tap water supply and water pipelines. This kind of anti-corrosion generally adopts outer epoxy coal tar anti-corrosion and inner IPN8710 anti-corrosion technology. The process is simple and the cost is low.


3PE anti-corrosion steel pipes and TPEP anti-corrosion steel pipes are commonly used for gas transmission and tap water transmission. These two anti-corrosion methods have high performance and a high degree of process automation, but the cost is generally higher than other anti-corrosion processes.


Plastic-coated steel pipe is the most widely used anti-corrosion process at present. The application areas include water supply and drainage, fire sprinklers, and mining. The pipeline anti-corrosion process is mature, and the anti-corrosion performance and mechanical performance are very strong. With low maintenance costs and long service life, it is gradually recognized and promoted by more and more engineering design units.


Spiral steel pipe is a semi-solid thermal sprayed plastic, usually filled with epoxy resin or polyurethane containing flame retardant, and then heat treated after coating to obtain a new pipe with good oxidation resistance and wear resistance. Because of its convenient construction, simple construction method, and ease to master and use, it is a kind of pipe widely used in my country at present. For the selection of anti-corrosion methods for spiral steel pipes, multiple factors such as application fields, construction environment, and cost budget need to be considered. The construction site can use pressure vessels to forge steel pipes according to needs, but attention should be paid to the construction environment, especially the dry treatment of the construction site.
