because PPH storage tank Under the same application conditions, its performance is better than that of tanks made of other materials in many aspects, so it has been used in the industrial production of the above industries and has a longer service life under natural conditions. It has many advantages, so before application, please carefully check the PPH water tank to ensure that it is convenient for you.

The appearance of PPH tank shall be checked before use, and its surface shall 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 shell test pressure of PPH tank valve 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 carried out under the nominal pressure, and the valve sealing surface is not allowed to leak.

For the pipeline gate valve of mechanical equipment conveying dangerous goods and flammable liquids, the working pressure test and sealing test of the pipeline gate valve shell with the design method working pressure greater than 1MPa and the design method temperature less than - 29 ℃ or the non flammable liquid with the design method temperature greater than 186C were tested respectively.

By observing the threaded surface outside the pph storage tank, plus the accuracy and surface roughness should conform to the design concept or specification, and there should be commodity differentiation.

Although PPH storage tank has good corrosion resistance, wear resistance, no leakage, no falling off, long service life and other advantages, it is an ideal storage and transportation equipment for transporting corrosive liquids, but it also has the shortcomings of solder skips.

PPH tank is a new type of anti-corrosion tank made of high-performance polypropylene (PPH) by extrusion winding process, which has better chemical resistance, high temperature resistance and good creep resistance.

Precautions for use of PPH storage tank:

PPH storage tank is made of polypropylene, which can hold inorganic acid, malic acid, salt, ammonium, alkali, oil and most of gaseous organic substances under normal temperature and pressure.

The crushing temperature of PPH storage tank is - 70 ℃, the softening temperature is 108 ℃, and the temperature of the liquid contained is usually between - 40 and 60 ℃.

PPH storage tank cannot be used to contain strong oxidants, such as concentrated sulfuric acid, concentrated nitric acid, etc.

PPH winding tank When acid and alkali liquids are contained, acid and alkali resistant gaskets shall be provided. When it contains organic solvents, it needs to be equipped with insoluble rubber gaskets.

If you are not sure whether it can contain the required substances, you can consult our technical personnel, and if necessary, you can conduct immersion test on the sample of tank material. Prepare for leakage defects.
