The physical and chemical properties of insulation materials in the arrival of the country's current product standards, but also to the green to the insulation pipe to do deep-buried "steel pipe steel pipe unique application requirements characteristics. Anti-corrosion is the most commonly used anti-corrosion method. It is characterized by simple manufacturing process, good anti-corrosion effect, and low price. It is a corrosion protection method widely recognized by the pipeline industry.

After the anti-corrosion treatment of the steel pipe increases the service life of the steel pipe, the details are also presented in the following aspects: the machine strength of the fusion steel pipe and the corrosion resistance of the plastic. The outer wall coating is more than 2.5mm, scratch resistance and resistance Bump. The inner wall reaches the national hygiene guidelines. The inner wall is not easy to foul and has self-cleaning properties.

Technical parameters of epoxy coal tar anticorrosion steel pipe: charge strength: kg·cm ≥ 502, viscosity: S (coating -4 cup) ≥ 453, attaching force (cross-cut method), ≤ dry time, h, ≤ surface dry

The cost of the pipeline must be comprehensively explored from the perspective of the entire cycle, not only to think about the cost of the pipe, but also to think about the device construction of the pipe, the subsequent operating costs and the use of life. Therefore, the municipal anticorrosive steel pipe becomes the first choice. Because the contraction coefficient of epoxy powder coating, steel pipe, heat-shrinking rubber sleeve and heat-shrinking sleeve polyethylene layer is different, so even if the heat shrinkable sleeve construction product is very good, it will follow the increase of pipe life.

The detailed manufacturing process of anti-corrosion steel pipe is to conduct inspection on the anti-corrosion steel pipe first, comprehensively presuppose the implementation of the steel pipe to make it suitable for the premise of manufacturing the thermal insulation steel pipe, test whether the steel pipe has been eroded, and inspect and remove the embroidery on the steel pipe. The rust-removing and anti-corrosion steel pipe is sheathed in a polyethylene pipe, and the pipe is molded. However, the entire head is repaired and the polyurethane foam is injected inside. It is necessary to fully fill the free space to make it fully filled. Inspection of anti-corrosion steel pipe, manufacturing The completed insulation pipe is tested for molded articles.

Anti-corrosion steel pipe can be useful to prevent or slow release of the life span of eroded elongated steel pipe, reducing the cost of steel pipe operation. Characteristics of anti-corrosion steel
