Overview

The fully automatic hydraulic testing machine for pipeline gas cylinders is a specialized equipment that uses water as the medium to automatically complete liquid filling, exhaust, pressure rise, pressure holding, pressure replenishment, pressure relief, and data recording. Its core is used for testing the pressure resistance strength, sealing, residual deformation, and bursting limit of pipelines/gas cylinders/pressure vessels. It is a core equipment for quality inspection, certification, and research and development.

Product Details

Pipeline gas cylinder pressure holding test machine, fully automatic water pressuretesting machine It is a fully automated process using water as the mediumFill, exhaust, boost, maintain, supplement, release, and record dataSpecialized equipment, core used forPipeline/Gas Cylinder/Pressure VesselofPressure resistance, sealing performance, residual deformation, explosion limitTesting is the core equipment for quality inspection, certification, and research and development.

1、 Core positioning and purpose

Pressure holding/withstand testMaintain pressure according to standards (several minutes to several hours), monitor pressure drop, and determine leakage and strength.
Gas cylinder external measurement method for water pressureGas cylinder testingVolume deformation and residual deformation rateDetermine whether it is qualified (GB/T 9251, ISO 11439).
blast testApply pressure until rupture, recordburst pressureEvaluate the ultimate strength.
Applicable subjectsSeamless steel cylinders, liquefied gas cylinders, fire gas cylinders; Metal/plastic/composite pipelines, valves, joints, pressure vessels.
