This depends on the pressure of the air outlet of your air compressor, that is, the working pressure of the air compressor. The purchase of the pipeline is determined according to the pressure of the air compressor. Generally, the pressure of 3-5KG is called low pressure, 7-13KG is called medium pressure, and more than 13KG is called high pressure.
Divided according to the size of the pressure.
Classification criteria:
1. Low pressure pipeline 0.1 ≤P≤ 1.6MPa
2. Medium pressure pipeline 1.6
3. High pressure pipeline 10
4. Ultra-high pressure pipeline P>100MPa
in a broad sense, pressure pipes refer to all pipes that bear internal pressure or external pressure, regardless of the medium in the pipe. The pressure pipe is a part of the pipeline. The pipeline is used to transport, distribute, mix, separate, discharge, measure, control and stop the flow of fluid. It is composed of pipes, fittings, flanges, bolt connections, gaskets, valves, and other components. An assembly assembly composed of parts or pressure parts and supports.

pressure pipe features:
1. The pressure pipeline is a system that is interrelated and affects each other, and affects the whole body.
2, the pressure pipe length diameter ratio is very large, easy to lose stability, the force is more complex than the pressure vessel. The fluid flow state in the pressure pipeline is complex, the buffer room is small, and the frequency of working conditions change is higher than that of the pressure vessel (such as high temperature, high pressure, low temperature, low pressure, displacement deformation, wind, snow, earthquake, etc. may affect the stress of the pressure pipeline).
3. There are many types of pipeline components and pipeline supports, and various materials have their own characteristics and specific technical requirements, and the selection of materials is complicated.
There are more possible leakage points on the pipeline than the pressure vessel, and there are usually five in only one valve.
5. There are many types and large quantities of pressure pipes, and there are many links in design, manufacturing, installation, inspection, and application management, which are very different from pressure vessels.
Medical gas plays the core role of "life support system" in medical treatment, and its importance is reflected in many dimensions, such as directly participating in patient treatment, ensuring the operation of medical equipment, maintaining surgical safety and infection control. The following is a systematic analysis: I
There are many choices of star wheel materials for single-screw oil-free and water-lubricated air compressors, including engineering plastics, phenolic resin plus glass fiber, epoxy resin plus glass fiber cross-weaving, and self-lubricating aviation-grade composite carbon fiber/tough epoxy resin base imported from Britain.
Screw unit and whirlpool machine are two different types of mechanical devices, which have significant differences in structure, working principle and application field. First of all, the core component of the screw unit is the compressor. The compressor may contain key groups such as screws.
The maintenance cycle of the screw air compressor is not fixed, but is affected by a variety of factors, including the type of equipment, working environment, frequency of use and manufacturer's recommendations. The following are some general guidelines on the maintenance cycle of screw air compressor: 1. maintenance
The setting requirements and specifications of the air compressor room are the basis to ensure the safe and stable operation of the air compressor. The following are the relevant contents sorted out according to multiple authoritative sources: 1. the site selection requirements of the air compressor room. Environmental requirements: Office areas that require noise and vibration should be selected far away.
Hospital air compressor room is an important part of hospital facilities, mainly for the hospital to provide a variety of medical equipment required by the compressed air. The following are the main functions of the hospital air compressor room: to provide power for medical equipment: the air compressor is the main production of compressed air
Q: air compressor is what equipment? A: for industrial machinery to provide compressed gas source, general machinery and equipment. shanghai granklin group limited company specializing in "water lubricated air compressor" production, our screw air compressor is not
The price of screw air compressor repair varies due to a variety of factors, including brand, model, fault type, repair scope, and service provider's pricing strategy. The following is some analysis and summary of the maintenance price of screw air compressor: 1. price range
The drainage of oil-free air compressor is an important maintenance step. The following are detailed drainage steps and precautions: Turn off the power 1. manual drainage steps: Before performing any maintenance operations, first make sure that the air compressor has been turned off and cut off the power. To ensure safety.
The standards for water-free and oil-free compressed air mainly involve the moisture and oil content in compressed air. These standards are essential to ensure the purity and applicability of compressed air. The following is a detailed analysis of the standard: 1. oil-free standard 1. ISO 8
