HDPE is a part of the plastic recycling market with rapid growth. This is mainly because it is easy to reprocess, has a limited degradation characteristics and is widely used in packaging. The main recycling is to reprocess 25% of recycled materials, such as post consumer recyclables (PCR), with pure HDPE to make bottles not in contact with food. In addition, due to the good insulation performance of HDPE storage tanks, polyethylene is used in many cables, and has good impact resistance even in low environment, In addition, this type of storage tank is more convenient for processing, and can be processed again after use, but it can not be used in industries directly contacting food after secondary processing.

The anti-corrosion means of PPH storage tank are cathodic protection and coating protection. Coating protection can be divided into two ways, namely, internal anti-corrosion treatment and external anti-corrosion treatment of PPH storage tank. For oil storage or product oil storage tanks, the required performance of anti-corrosion coating in the tank is electrostatic conduction. Therefore, in the process of anti-corrosion treatment of storage tanks, electrostatic conductive coatings are used for anti-corrosion treatment of storage tanks. The treatment of anti-corrosion coating outside the tank is to combine the anti-corrosion performance, weather resistance and aesthetic performance of the tank. In the design of anti-corrosion coating for PPH tank, the temperature resistance characteristics between anti-corrosion coatings must be considered, which is interchangeable. In the alkyd anti-corrosion coating, direct combination use must be avoided. This is because of chemical reaction with zinc powder. Cathodic corrosion protection of storage tank includes impressed current cathodic protection of storage tank bottom plate and protection treatment of storage tank ponding layer anode. Cathodic corrosion protection of storage tank is divided into impressed current cathodic protection on the outside of the bottom plate of the storage tank, and protective treatment on the anode of the ponding layer in the tank.

When the storage tank made of polyethylene is produced and processed again, it does not need to use traditional welding, so its volume will be larger when it carries liquid. Because the HDPE storage tank does not need to be welded, so there is no weld. When it is used again, it does not need to worry about instability due to too much carrying liquid. Generally speaking, most storage tanks have a stability coefficient. The reason why the stability performance of storage tanks is different is that the performance of raw materials used is different. If the materials used are poor, even if the process is good, the stability performance is not guaranteed. When selecting raw materials for storage tanks, the first thing we should do is to check the quality certificate and inspection report of the raw materials. After checking, all data can be put into production only if they meet the standards. Besides, plates are used at the top and bottom of the tank, so there are requirements for plates.

Welding technology of PPH storage tank. In terms of automatic welding equipment and welding materials for large storage tanks, the degree of localization is not high enough, especially the automatic welding wire matching the imported high-strength steel plate, which still depends on imports and has high prices. This is a problem that China's PPH storage tank manufacturers must solve in the future; The research and application history of submerged arc automatic transverse welding for flip chip storage tank is not long, and there are still many problems to be solved; There is no doubt that CO2 semi-automatic gas shielded welding technology has obvious advantages over traditional shielded metal arc welding, but there are still many problems to be solved if this method is to be widely popularized and applied outdoors. First, the auxiliary equipment should be portable and flexible, and the wiring should have sufficient length. According to different weldments or parts, corresponding wind proof auxiliary devices shall be developed. It can be predicted that the development trend of welding technology of pph tank manufacturers will have a good application prospect in the welding fields such as petrochemical industry; Gas shielded welding with flux cored wire will be the development direction of large pph tank manufacturers. In the welding of low-temperature storage tank, automatic welding is beneficial to ensure the stability of low-temperature impact performance of heat affected zone.
