描述

3PP anticorrosive steel pipe is a steel pipe polypropylene anticorrosive coating, which is characterized by good heat resistance.

It is widely used in coating for all kinds of major pipeline engineering.

Most of the large pipeline anti-corrosion in China is 3PE coating, and 3PP and 3PE coating belong to the multi-layer coating system, which consists of the bottom epoxy powder, the intermediate layer binder and the outer PP jacket. The performance of PP is similar to that of PE, and 3PP coating is fully capable of producing 3PP coating with 3PE production line, and no special 3PP coating operation line is required. However, the difference in performance of PP and PE materials, and the performance of 3PP and 3PE coating, can be applied to different environments. The advantages of 3PP coating on certain properties make it possible to play a role in areas where 3PE coatings are not available, so there are many pipeline projects abroad that use 3PP anti-corrosion coatings. At present, it is mainly foreign products that are related to the environment, for some countries with high environmental temperature, and PP is harder than PE, so as to avoid scratch coating.

3PP preservation:

PP three-tier structure of anti-corrosion pipeline: the first layer of epoxy powder (FBE50 – 100um), the second adhesive (AD) 250 – 400um, the third layer of polypropylene (PP) 1.4 – 4.0mm. Three of the integration, and steel pipe with a good solid coating, Coating temperature up to 110 degrees.

Single-layer anti-corrosion epoxy powder pipe

The coating has a coating has the advantages of simple operation, no pollution, coating resistance and bending resistance, high temperature and other characteristics, has been applied widely overseas.

It is nearly 30 years ago to develop a new type of coating, using electrostatic spray coating of epoxy powder coating, the first film. The coating is coated with easy to operate, pollution-free, coating and anti-bending performance impact, and of high temperature, in foreign countries has been widely used.
