Description

Technical Field

[0001] The utility model relates to the technical field of plastic-coated steel pipes, in particular to a device for measuring the compression resistance of plastic-coated steel pipes. Background Art

[0002] Plastic-coated steel pipe, also known as plastic-coated pipe, steel-plastic composite pipe, plastic-coated composite steel pipe, plastic-coated steel pipe has the advantages of high strength, easy connection, corrosion resistance, etc. In the process of transporting substances, it is necessary to pressurize the substances into the plastic-coated steel pipe, and then use the pressure to push the substances to be transported in the plastic-coated steel pipe. When using the plastic-coated steel pipe, it is necessary to measure the compressive resistance of the plastic-coated steel pipe. When measuring the compressive resistance of the plastic-coated steel pipe, it is necessary to use a device for measuring the compressive resistance of the plastic-coated steel pipe.

[0003] In the prior art, there are the following problems:

[0004] Usually, when measuring the pressure resistance of plastic-coated steel pipes, most of the measures are taken to measure the strength of the plastic-coated steel pipes under the pressure of external objects, which is not convenient for measuring the internal pressure generated by the plastic-coated steel pipes when transporting substances. The existing solution is to seal the two ends of the plastic-coated steel pipe and then rush air into the plastic-coated steel pipe to gradually increase the air pressure inside the plastic-coated steel pipe, thereby measuring the pressure resistance inside the plastic-coated steel pipe. However, the existing measuring device uses two sealing covers to clamp the two ends of the plastic-coated steel pipe and then close and move the sealing covers to squeeze and clamp the two ends of the plastic-coated steel pipe. During the measurement, the plastic-coated steel pipe is easily squeezed inward by the force of the two ends, resulting in deviations in the measurement. At the same time, it is not convenient to perform measurement and comparison operations on multiple plastic-coated steel pipes at the same time, and it is not convenient to install and fix the plastic-coated steel pipes and protect them during measurement. Utility Model Content
