Let me introduce the application process for the 8710 anti-corrosion coating used in drinking water systems.

Pipelines transporting oil and gas are typically exposed to complex soil conditions, and the conveyed media are often corrosive, making both the inner and outer surfaces susceptible to corrosion. Once a pipeline is corroded through and develops a leak, it can lead to the loss of oil or gas, disrupting transportation, polluting the environment, and even triggering fires that pose serious hazards. According to statistics from the U.S. pipeline industry, direct losses attributable to corrosion reached US$600 million in 1975. Consequently, preventing pipeline corrosion is a critical aspect of pipeline engineering.

Pipelines transporting oil and gas are typically exposed to complex soil environments, and the conveyed media often exhibit corrosive properties, making both the inner and outer pipe walls susceptible to corrosion. Once a pipeline is corroded through and develops a leak, it not only disrupts transportation but also contaminates the environment and may even trigger fires, posing significant hazards. According to statistics from the U.S. pipeline industry, direct losses attributable to corrosion reached US$600 million in 1975. Consequently, preventing pipeline corrosion is a critical aspect of pipeline engineering. In response, protective technologies have been developed to shield pipelines from corrosion caused by soil, atmospheric conditions, and the transported media—such as petroleum and natural gas. The “IPN” series of anti-corrosion coatings exhibits outstanding performance characteristics, including high strength, excellent toughness, resistance to abrasion and aging, and superior resistance to acid, alkali, and salt corrosion. They also offer strong adhesion, resistance to hydrolysis, and tolerance to fuels like gasoline and kerosene, while being non‑toxic and non‑flammable. As a result, these coatings find broad applications—not only for steel protection but also for non‑metallic substrates such as concrete and wood. In recent years, they have been extensively employed in water‑supply systems, power plants, chemical facilities, fertilizer plants, and other industrial sectors, providing corrosion protection for equipment, oil, gas, and water transmission pipelines, as well as for civil‑engineering structures both aboveground and underground.

8710 potable‑grade anti‑corrosion coating is formulated by esterifying and polymerizing epoxy resin with vegetable oils, then blending it with organic solvents, additives, pharmaceutical‑grade zinc oxide, extender pigments, and a curing agent. It is supplied as a two‑component system, to be mixed at a ratio of 10:1. This coating is non‑toxic and environmentally friendly, offering excellent corrosion resistance. It can withstand prolonged exposure to sunlight and immersion in water, producing a hard, durable film with strong adhesion, superior chemical stability, and outstanding resistance to moisture, oil, and aging. It is widely suitable for internal and external corrosion protection of municipal water pipelines, as well as for the corrosion prevention of steel structures and equipment in municipal engineering and urban development projects.

8710 anti-corrosion coating is an environmentally friendly coating product that provides exceptional corrosion protection for pipelines, preventing contamination of the conveyed media caused by inadequate pipeline protection. Produced by Guangxi Nanning Canghai Steel Pipe Co., Ltd., the 8710 drinking‑water anti-corrosion coating offers robust protective performance for various types of tap water and potable water pipelines. Today, we will introduce the application process for 8710 drinking‑water anti-corrosion coating:

(1) Prior to pipeline installation, all steel pipes and steel pipe fittings must undergo surface treatment. Before applying anti-corrosion coatings, the inner and outer surfaces of the steel pipes shall be derusted to remove surface contaminants, loose rust, iron oxide, welding slag, and other foreign matter, with a derusting grade meeting the St3 standard.

(2) When the temperature drops below 5°C in winter, the curing reaction slows down, making construction inadvisable.

(3) If the coating is too thick, it should be diluted with a dedicated thinner.

(4) Observe fire safety precautions and store in a well-ventilated, cool place.
