New requirements for blasting test rig?

New requirements for blasting test rig (2025mur2026 new edition standard emphasis, including metal flat pipe / pipe / hose) Core update: GB/T 241-2025 "hydraulic Test methods for Metallic material Tubes" 2026-01-01; GB/T 5563-2025 "Rubber and plastic hoses and hose assemblies-hydrostatic Test methods" 2026-03-01, which is the national standardization of two key new standards approved by CNAS and the upgrading of blasting test-bed equipment.

New acceptance requirements for hydraulic test-bed for fire cylinders?

Carbon dioxide cylinders, IG541 fire protection cylinders, require the use of external testing method hydraulic test bench Implementation standard: GB/T 9251-2022 "cylinder hydraulic Test method", TSG23 2021 cylinder Safety Technical Specification, GB/T35015 (Standard cylinder Calibration) Core values: hydraulic test equipment that can measure [volumetric residual deformation rate], mandatory requirements for periodic inspection of gas cylinders.

Requirements for evaluation of hydraulic test-bed for welded gas cylinders?

The current new standard (core: GB/T 9251-2022 "hydraulic Test method for Gas cylinders", implemented in 2022-10-01, replacing the old version GB/T 9251-2011) national standardization. The equipment, instrument, test flow and data acquisition of the welded gas cylinder hydraulic test-bed are all in accordance with this standard; the matching standard for welded gas cylinder products / periodic inspection: GB/T 9251-2022 + GB/T 13075 "periodic inspection and evaluation of steel welded gas cylinders"

What are the specific requirements of the new safety valve calibration standard for the safety valve calibration table?

TSG 92mur2026 requirements for modification / change of off-line calibration table for old safety valves Conclusion: the old equipment is not forced to be scrapped, but it must meet the rigid conditions of the Appendix DC calibration device; if it does not reach the standard, it cannot be used for legal verification, and the calibration report issued is invalid national market supervision. The following is divided into [compulsory hardware modification] [software / data recording transformation] [test vessel (high pressure warehouse)] [pipeline and pressure regulation] [parts that do not need to be changed] [confirmed after modification]

How to select the gas-liquid booster pump?

Principle of gas-liquid booster pump: compressed air drives large pistons to push small plunger pressurization; maximum output pressure = drive gas source pressure × booster ratio; pressure reaches the set value to automatically stop and maintain pressure, and automatically replenish pressure in the event of leakage. typical scenarios without continuous energy consumption: blasting test, pressure test, safety valve calibration, pipe expansion, hydraulic fixture, valve static pressure test
