PPH tank is a steel container for storing polypropylene. PPH storage is mainly used for the storage and transportation of polypropylene. The plastic storage tank is characterized by good integrity of multiple molding, no weld, no water seepage, strong impact resistance, high compressive strength, and aging resistance. It has many advantages, so please carefully check the PPH tank before use to ensure that it is convenient for you.
PPH storage tank The appearance shall be checked before use, and the surface shall be free of cracks, shrinkage cavities, slag inclusions, folds, crusts 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 storage tank valve shall be less than 1.5 times of the nominal pressure, the test time shall be within 5 minutes, and the shell filler shall not leak; The sealing test pressure shall be carried out under the nominal pressure, and the sealing surface of the valve shall not 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 protruding surface of the external thread of PPH storage tank, its precision and surface roughness should conform to the design concept or specification, and there should be commodity differentiation.
PPH is a high molecular weight, low melt index β- The modified polypropylene has chemical resistance, high temperature resistance and corrosion resistance. Especially after the extrusion winding process is adopted, there is no weld compared with the original sheet metal processing process.
PPH winding tank It is applicable to a wide range of industries. PPH winding tank manufacturers are generally only responsible for the design, production, loading and transportation of tanks within the project scope. The subsequent uninstallation and installation are the responsibility of the customer. The manufacturer arranges the project manager to guide the unloading at the site, but generally the manufacturer does not have so many project managers to assign, so it is particularly important for the customer to know how to unload the PPH winding tank. In terms of unloading, before the storage tank is transported to the installation site for unloading, it is recommended that the customer representative inspect the storage tank to confirm that the storage tank is not damaged during transportation. Pay attention to the following points when unloading:
Accessories on the storage tank shall not be stressed, and it is strictly prohibited to use objects with sharp edges for hoisting, such as steel wire ropes, iron chains, etc;
The small storage tank is fixed with ropes in a proper way to facilitate unloading;
The large storage tank shall be placed vertically, and the bottom shall be protected to prevent abrasion. Slings shall be used during operation.
