Anti-corrosion steel pipes refer to steel pipes that have been processed by anti-corrosion technology, which can effectively prevent or slow down the corrosion phenomenon caused by chemical or electrochemical reactions during transportation and use. Generally, it refers to the anti-corrosion treatment of ordinary steel pipes (such as seamless pipes and welded pipes) by special processes, so that the steel pipes have certain anti-corrosion capabilities. Generally, it also has the characteristics of waterproof, anti-rust, anti-acid and alkali, and anti-oxidation. Generally speaking, PE anti-corrosion steel pipe refers to polyethylene anti-corrosion steel pipe, which is a tubular article processed by advanced science and technology. PE anti-corrosion steel pipes are widely used in oil, natural gas, city gas, city water supply, coal-water slurry pipelines, etc.
Corresponding anti-corrosion measures can also be carried out on the inner and outer walls of the steel pipe according to different requirements. The common ones are epoxy coal tar pitch anti-corrosion steel pipe, polyurethane coating anti-corrosion, cement mortar anti-corrosion on the inner wall of anti-corrosion steel pipe, etc. Anti-corrosion steel pipe is mainly used in engineering fields with special requirements or in harsh environments.
Corrosion factors of pipelines:
1. Electrochemical dissolution corrosion. Soil is a complex mixture of solid, liquid and gaseous three-phase substances. Due to the presence of water and ion-conducting salts in the soil environment, the soil structure has the characteristics of different electrolyte solutions, which constitute electrochemical dissolution and corrosion of metal parts.
2. Due to the influence of external leakage current, stray current can pass through the soil, causing stray current corrosion.
3. The action of bacteria in the soil environment leads to biocorrosion.
What are the uses of anti-corrosion steel pipes
1. The base material of anti-corrosion steel pipe includes spiral pipe(SSAW pipe), straight seam pipe, seamless pipe and so on. Widely used in pipeline engineering fields such as long-distance water transmission, petroleum, chemical industry, natural gas, thermal power, sewage treatment, water source, bridge, steel structure, marine water transportation piling, etc.
2. Anti-corrosion steel pipes are widely used in oil, natural gas, city gas, city water supply, and coal-water slurry pipelines.
Compared with ordinary steel pipes, what are the characteristics of anti-corrosion steel pipes
1. Anti-corrosion steel pipe has corrosion resistance, no leakage, high toughness, excellent flexibility, good scratch resistance, and good fast crack resistance. Anti-corrosion steel pipe can reach more than 50 years of life in an environment greater than or equal to 60 degrees Celsius.
2. The anti-corrosion steel pipe with liquid epoxy coating IPN8710 is used to initiate polymerization at room temperature. The two can learn from each other and produce a synergistic effect. The coating film is non-toxic, high solid and low viscosity. It is a new type of anti-corrosion coating with strong adhesion, high strength, abrasion resistance, hydrolysis resistance, corrosion resistance, water resistance and weather resistance. And the requirements for rust removal on the surface of the steel structure are not high, and the service temperature can be within the range of -20~120°C.
3. The anti-corrosion steel pipe with epoxy coal tar pitch combines the characteristics of high mechanical strength, strong adhesion, chemical medium corrosion resistance and asphalt water resistance, anti-microbial and anti-plant root system characteristics of epoxy resin. It is a high-performance anti-corrosion insulating coating with good chemical resistance and water resistance.
The advantages of anti-corrosion steel pipe in practical application
1. Longer lifespan. Ordinary steel pipes have a certain lifespan. After ordinary building materials are treated with anti-corrosion technology, their lifespan can be as long as 20-30 years or even longer, which saves the cost of replacement and maintenance for enterprises.
2. The construction method is simple, the steps are fast, and construction can be carried out in factories and construction sites. Compared with the old steel pipes, the construction of anti-corrosion steel pipes is very simple, does not require major equipment and sites, and is suitable for on-site operations.
3. The cost of construction projects is cheap. Compared with the quality and service life of ordinary steel pipes, anti-corrosion steel pipes are more economical and applicable than traditional steel pipes.
4. Anti-corrosion steel pipes are designed with environmental protection as the center. Today, where environmental protection is emphasized, this design is more in line with the needs of the progress of the times. In the future, the environmental protection requirements for the carrier pipelines that transport fluids will become more and more stringent, and products that cannot keep up with the environmental protection development of the times will eventually be eliminated.
Anti-corrosion steel pipe has corrosion resistance and excellent flexibility, and is a good steel pipe material. Anti-corrosion steel pipes have various uses and can be used in many fields such as natural gas, heat, sewage treatment, etc.
