The pipelines that transport oil and gas are mostly in a complex soil environment, and the conveyed media are also more corrosive, so the inner and outer walls of the pipeline may be corroded. Once the pipeline is corroded and perforated, it will cause oil and gas leakage, which not only interrupts the transportation, but also pollutes the environment and may even cause a fire and cause harm. According to statistics from the US pipeline industry, direct losses due to corrosion amounted to $ 600 million in 1975. Therefore, preventing pipeline corrosion is an important part of pipeline engineering.

Therefore, preventing pipeline corrosion is an important part of pipeline engineering. The drinking water 8710 anti-corrosion steel pipe avoids the pipeline, and the protection technology of corrosion of soil, air and transmission medium (oil, natural gas, etc.) came into being. "IPN" series anti-corrosion coatings have high strength, high toughness, erosion resistance, aging resistance, acid and alkali salt corrosion resistance, strong adhesion, resistance to hydrolysis, gasoline, kerosene and other media, non-toxic and non-combustible and other excellent properties. Therefore, it is widely used, not only for anti-corrosion of steel, but also for non-metallic components such as concrete and wood. In recent years, it has been widely used in the equipment of industrial departments such as water supply engineering, power plants, chemical industry, chemical fertilizers, etc., and anti-corrosion engineering for underground and above-ground projects such as oil pipelines, gas pipelines, and water pipeline systems.

8710 drinking water grade anticorrosive coating is prepared by esterification polymerization of epoxy resin and vegetable oil with organic solvent, auxiliary agent, medicinal zinc oxide, body pigment and curing agent, two-component packaging, 10: 1 conversion. The paint has the characteristics of non-toxic and non-polluting, and is a kind of paint with good anti-corrosion performance. It can be exposed and immersed in water for a long time. The paint film is hard and durable, with good adhesion, good chemical stability, moisture resistance, oil resistance and aging resistance. It is widely used for anticorrosion of internal and external water pipes, municipal engineering, urban construction and other steel structures and equipment.

8710 anti-corrosion coating is an environmentally friendly coating product, which has a strong anti-corrosion effect on the pipeline and prevents pollution of the medium in the pipeline due to the anti-corrosion of the pipeline. , Water supply pipes, etc. have a very strong anti-corrosion protection, today I will introduce the construction technology of 8710 drinking water anti-corrosion coating:

(1) All steel pipes and steel pipe fittings need to be surface-treated before the pipeline is installed. Before the anti-corrosion construction, the inner and outer walls of the steel pipe should be derusted to remove surface impurities, floating rust, and iron oxide from various types of pipes , Welding slag, etc., its rust removal level reaches St3 standard.

(2) When the temperature is lower than 5 ℃ in winter, the curing reaction is slow and construction is not suitable.

(3) If the paint is too thick, it should be diluted with special thinner.

(4) Pay attention to fire prevention and store in a cool and ventilated place.
