Abstract

The invention discloses a sealing test device for metallurgical cold-rolled pipelines, which is characterized in that it comprises a pressure testing unit and a sealing box, and a plurality of through holes are opened on the flat plate of the sealing box, and the flat plate is a rectangular Q235 steel plate Material; the sealed box is a cuboid, the pressure test unit includes a pressure test pump and a pressure gauge, connected to the sealed box through galvanized pipes, and several reinforcing ribs are arranged on the sealed box. The invention avoids the laying cost of traditional boiler pipes, greatly saves the later use cost, has low use cost, no pollution, achieves the effect of energy saving and environmental protection, and conforms to the national energy utilization policy.

Description

technical field [0001] The invention relates to a testing device for mechanical components, in particular to a sealing testing device for metallurgical cold-rolled pipes. Background technique [0002] The existing device has defects such as long cycle, high cost, inconvenient operation, etc., and after the expansion test and pressure test are completed, the manufactured expansion test device and pressure test device will be discarded and need to be redone when the test is performed next time. Production, therefore, also brings unnecessary waste. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an integrated and reusable metallurgical cold-rolled pipe sealing test device. [0004] In order to solve the above-mentioned technical problems, a metallurgical cold-rolled pipe sealing test device according to the present invention is characterized in that it includes a pressure test unit and a sealing box, and several th...
