Recently, Zhenghe Group completed tests on its liquefied petroleum gas spherical tank. The results showed that all tanks are qualified and can be safely used for the next five years before requiring further tests.
The test took five months, and the company made significant preparations in advance. It held special test work meetings and reviewed the construction plans of the testing unit, which ensured the efficient and safe running of the test. The company overcame storms, high temperatures and other severe weather conditions to successfully finish the test. At the same time, it also performed mechanical de-rusting on the spherical tank’s ladder stands and some pipes and equipment suffering severe corrosion, effectively prolonging the service life of the spherical tank.
