Priority Pressure for Compressors, Rock Drilling Machinery and Pneumatic Tools - GB4974-89
This article looks into GB4974-89, a safety standard for pressure vessels in China. It covers the design, manufacture, inspection, installation and use of pressure vessels, compressors, rock drilling machinery, and pneumatic tools. It is relevant to anyone interested in the safe use of pressure vessels, compressors, rock drilling machinery, and pneumatic tools in China.
Firstly, General Specifications outlines the requirements which all machines must meet in order to be considered compliant with GB4974-89. It is important that all relevant personnel understand the implications of this section.
Pressure Vessels: The design, manufacture, installation and operation of pressure vessels must be in accordance with GB4974-89. This includes their design and inspection, as well as specific requirements for the material and welding used in their manufacture. The pressure vessels must also have a safe working pressure, taking into account the environment in which they are intended to be used.
Compressors: Compressors must be constructed, tested and inspected in accordance with GB4974-89. There are specific requirements for the design, construction and operation of these machines, and safety measures must be taken before and during their use. Inspection should take place both before and after use, and the pressure should be adjusted to ensure the compressor is working properly and not exceeding its safe working pressure.
Rock Drilling Machinery: Must be constructed and tested according to GB4974-89. This includes specific safety requirements for the design, construction and operation of this machinery. There is a specific requirement for the safe use of rock-cutting tools, as well as standards for the safe working pressure and maximum thrust force of the equipment.
Pneumatic Tools: Pneumatic tools must also be constructed, tested and inspected in accordance with GB4974-89. There are specific requirements outlining safe handling procedures and the safe working pressure of the tools and the surrounding environment.
In conclusion, the priority pressure requirements of GB4974-89 cover a wide range of pressure vessels, compressors, rock drilling machinery, and pneumatic tools. This standard is important to understand if you are going to use any of these machines in China. Compliance is important for the safe use of the machines, and inspections should take place before and after use to ensure that the machines are working within their safe working pressure.
