Introduction to anti-corrosion steel pipes
Anti corrosion steel pipe is a special type of steel pipe, and by treating its surface with anti-corrosion treatment, its corrosion resistance and service life can be improved. 

Types of anti-corrosion steel pipes
There are various types of anti-corrosion steel pipes, including 3PE anti-corrosion steel pipes, IPN8710 anti-corrosion steel pipes, fiberglass anti-corrosion steel pipes, and epoxy coal tar anti-corrosion steel pipes
3PE anti-corrosion steel pipe: This is a type of anti-corrosion steel pipe with a three-layer structure, consisting of a polyethylene (PE) layer, an adhesive layer, and a polyethylene (PE) layer from the inside out. The adhesive layer in the middle plays a role in bonding and waterproofing, effectively preventing corrosion inside the pipeline. The advantages of 3PE anti-corrosion steel pipes lie in their excellent corrosion resistance, wear resistance, impact resistance, and low-temperature performance.
IPN8710 anti-corrosion steel pipe: This is a type of anti-corrosion steel pipe with a double-layer structure, consisting of a polymer anti-corrosion layer and a polymer protective layer from the inside out. The polymer anti-corrosion layer has strong resistance to acid and alkali, oil and grease, and low temperature performance, which can effectively protect the surface of pipelines from corrosion; The polymer protective layer enhances the rigidity of the pipeline and protects the surface of the pipeline. IPN8710 anti-corrosion steel pipe is suitable for various chemical industry environments and can significantly improve the service life of pipelines.
Fiberglass anti-corrosion steel pipe: This type of pipe is made of inorganic material glass fiber reinforced resin composite material. It has the characteristics of light weight, high strength, corrosion resistance, insulation, etc. FRP anti-corrosion steel pipes are widely used in fields such as drinking water, sewage, and seawater, which can effectively improve the service life of pipelines.
Epoxy coal tar anti-corrosion steel pipe: This is a type of anti-corrosion steel pipe coated with epoxy resin and coal tar adhesive. Its advantages include uniform coating, strong adhesion, good corrosion resistance, and the ability to resist the erosion of various chemicals and oxidants, thereby ensuring that the pipeline is not corroded. In addition, epoxy coal tar anti-corrosion steel pipes also have good low temperature resistance and wear resistance.

Application fields of anti-corrosion steel pipes
Anticorrosive steel pipes have the characteristics of corrosion resistance, aging resistance, wear resistance, etc., and can be used for a long time in harsh environments. Its application fields are very extensive, mainly including the following aspects:
Construction industry: Anti corrosion steel pipes are widely used for anti-corrosion coating of building structures and corrosion protection of pipeline systems. It can be used for anti-corrosion treatment of building materials such as roofs, floors, walls, and can also be used for anti-corrosion treatment of pipeline systems such as water supply, drainage, HVAC, etc.
Chemical industry: Anti corrosion steel pipes play a crucial role in the chemical industry. Due to the frequent need to handle corrosive substances in chemical production, the use of anti-corrosion steel pipes can ensure the safe and stable operation of pipelines.
Petroleum industry: The petroleum industry involves a large amount of oil and gas transportation and storage, therefore anti-corrosion steel pipes are needed for pipeline construction. Anti corrosion steel pipes have high pressure resistance, temperature resistance, and good corrosion resistance, which can effectively meet the needs of the petroleum industry.
Seepage industry: Anti corrosion steel pipes can also be used for waterproofing treatment in the seepage industry. By using anti-corrosion steel pipes, it is possible to effectively prevent groundwater, rainwater, and other substances from seeping into the interior of buildings, providing protection.

Manufacturing process of anti-corrosion steel pipe
The manufacturing process of anti-corrosion steel pipes mainly includes the following steps:
Pre coating treatment: Before coating, the surface of the base iron must be treated with Sa2.5 grade. It is strictly prohibited to bring in moisture, dust, and oil stains during construction to ensure the quality of the coating.
Coating ratio: The coating ratio is 9kg of component A (base material) and component B (curing agent). Paint: 1kg of curing agent (or apply according to the ratio specified by our factory).
Construction ratio method: Open the mouth of component A, add component B into component A, and mix thoroughly. After 30 minutes of curing, the coating can be applied.
Construction requirements: This material is required to be used as needed, and the mixed coating must be used up within six hours. Unfinished materials should be sealed and stored. Construction should be stopped on rainy days or when the relative humidity exceeds 75%. For areas with severe corrosive media, it is recommended to apply multiple coats of paint.
Storage requirements: The product should be stored in a cool and dry place, protected from direct sunlight, isolated from sources of fire, and kept away from heat sources. The storage period is twelve months, and after the expiration, various technical indicators should be inspected. If the indicators meet the requirements, it can continue to be used.

In summary, anti-corrosion steel pipe is an important pipeline material with various types and wide application fields. Through reasonable manufacturing processes and anti-corrosion treatments, the corrosion resistance and service life of steel pipes can be greatly improved
