- High pressure valve material requirements
In order to improve the ability of ultra-high pressure valves to resist erosion and wear, anti-corrosion materials are usually selected
1. Materials with high hardness
2. Materials with acid-resistant protective film
3. Materials with high yield point and good stability
4. Materials with high fatigue strength
To improve the various properties of materials, one is to use alloying, and the other is to use appropriate heat treatment. The alloying method is to develop new materials with various special properties by changing the chemical composition of steel. The heat treatment method does not change the chemical composition of the steel, but applies different heating, insulation and cooling to the steel in the solid state to change the structural structure of the steel and improve the performance of the material.
- Typical applications of high-pressure valve air tightness testing equipment
Provides static and burst testing of pipe fittings, hoses, valves, pressure vessels, cylinders, etc.
Static and dynamic testing of aerospace accessories after repair
- Safety valve calibration
Hydraulic test of valves and wellhead devices
Inspection of air pressure regulator
Car braking system testing
Can pressurize oxygen, nitrogen, oxygen, air, methane and other gases
Suitable for air tightness testing of various medium and high pressure valves such as small and medium diameter gate valves, cut-off valves, check valves, plug valves, ball butterfly valves, diaphragm valves, etc.
