PPH storage tank Its production method is one-time forming winding method, which can be said to be relatively simple in structure and convenient in application.

Due to the low application frequency of PPH storage tank in normal use, only static load and slightly larger performance are generally considered. When the storage tank has a large requirement for capacity, concrete rubber support and metal rubber support need to be considered, because there will be a certain amount of plastic folding, expansion and other reasons, which will harm the compression strength of the storage tank when the rubber support is too tight, Considering the small bearing capacity of plastic rubber bearing.

1. When the rubber support of PPH storage tank is plastic rubber support, the compressive strength, stiffness, service life and total number of manufacturing shall be considered.

2. For rubber bearings, metal rubber bearings shall be the same as other standards. In addition, the surface layer of metal rubber bearings shall be subject to corrosion resistance treatment.

3. When the rubber bearing is a concrete rubber bearing, the compressive strength should be considered according to the PPH tank concrete rubber bearing, so there should always be two rubber bearings. The rubber bearings should be designed to maintain the elevation at the same time, without uneven ground settlement and the bottom needs to be leveled.

It is understood that the design scheme of PPH tank is simple in structure and convenient in use. Attention should also be paid to the method of special rubber support. Different quantities of rubber brackets and their application materials need to be selected according to their application sites. PPH winding tank

The appearance of PPH tank should be checked before use, and the surface should be free of cracks, shrinkage cavities, slag inclusion, folding, skinning and other defects. The depth of corrosion and indentation damage shall not exceed the negative wall thickness deviation allowed by the corresponding product standard.

The test pressure of PPH tank valve shell must be less than 1.5 times of the nominal pressure, the test time must be within 5 minutes, and the shell filler must not leak; The sealing test pressure must be under the nominal pressure, and the valve sealing surface is not allowed to leak.
