At present, 3PE anti-corrosion steel pipes are widely used in China
At present, the main popular type of domestic anti-corrosion steel pipe is 3PE anti-corrosion steel pipe, which is widely used in various fields due to its excellent characteristics and moderate price. And with the continuous development of technology, new types of anti-corrosion continue to gradually join the market. The characteristics and practical applications of polyurethane coatings are described below.
The characteristics of the external insulation of the outer wall of the molded rigid foam polyurethane are that the loss is low, the pollution is less, the low-carbon production can achieve the effect of waterproof and thermal insulation at the same time, 100% has no cavity, and the adhesion with the base layer is strong, not hollow, It does not fall off or crack, and the template position can be adjusted freely according to the design thickness. The construction is convenient, the requirements for operators are low, and the quality is easy to control. Problems such as difficulty in controlling the thickness of the foamed foam by direct spraying, poor flatness, needing to be leveled with an electric planer after spraying, and large loss can be well solved.
