Description

Technical Field

[0001] The utility model relates to the technical field of pressure testing mechanisms, in particular to a petrochemical container pressure testing tool. Background Art

[0002] Container refers to a basic device that is used to hold materials and is mainly composed of a shell. It is often used as the shell of storage equipment or other chemical equipment. It is mainly composed of a shell, a head, a pipe, a flange and a support. The basic requirements for containers are: meet process needs; ensure operational safety, including sufficient strength, rigidity and sealing; corrosion resistance, and a certain service life; easy to manufacture, install, maintain and use; low cost, material saving, especially saving precious materials such as stainless steel and non-ferrous metals.

At the same time, noise pollution will be generated during pressure testing, which will also reduce the practicality of the test tooling. Utility Model Content
