Experiments show that PPH has strong chemical resistance. Especially after the extrusion winding process is adopted, compared with the original plate processing process, there are no welds, seams and leakage problems, and the mechanical strength and safety reliability are greatly improved. These characteristics are very suitable for the process requirements in the new energy field. Experiments show that PPH has strong chemical resistance.

In practical engineering applications, vertical PPH winding tank Because the application frequency is not high, only the static load is considered, and the safety factor is slightly enlarged. As for the horizontal PPH winding tank with large volume, the concrete support can be considered too tight, and the plastic has certain shrinkage, which will affect the strength of the tank, and the appearance is not beautiful. Therefore, it is recommended to use concrete support, and for the tank with small volume, the plastic support can be considered directly. There are also some differences in the foundation of PPH seamless winding tanks.

1. When the support is concrete support, first of all, the concrete support of horizontal storage tank shall meet the strength requirements, and the number of supports shall be 2. When there are multiple supports, their elevations shall be the same, and there shall be no uneven settlement, and the bottom foundation shall be flat.

2. When the bearing is a metal bearing, other conditions shall be the same as 1. At the same time, anti-corrosion treatment shall be stopped on the surface of the metal bearing.

3. When the bearing is plastic, strength, rigidity, service life and manufacturing quantity shall be considered.

PPH winding tank is a kind of large plastic storage tank, and it is also a kind of plastic storage tank with promising prospects today. The advantage of PPH winding tank is mainly due to the change of processing technology, which makes it stand out among many tanks. PPH storage tank
