When purchasing stainless steel metal hoses, a number of key factors need to be considered to ensure that the selected product can meet the actual needs and have good performance. Here are some key considerations and recommendations:

First, material quality

1. Stainless steel grade

• considerations: The grade of stainless steel directly affects its corrosion resistance and mechanical properties.
• Recommendation : Give priority to high grades of stainless steel, such as 304 or 316 stainless steel, which have better corrosion resistance and strength. Its brand can be detected by stainless steel identification potion to ensure reliable quality.

2. Weaving effect

• Considerations: The quality of the braided layer determines the durability and pressure resistance of the hose.
• Recommendation : Check the pore size of the gap between the braided layer strand and strand, the smaller the pore size, the higher the density and the better the quality. Choose products with tight weaving and no loose phenomenon.

3. Other accessories materials

• Considerations: The material and quality of accessories such as hose joints and nuts are equally important.
• Recommendation : Check whether the accessories are made of high-quality materials, such as whether the copper nuts are polished and chromed, and whether the surface is smooth and burr free. Select accessories with exquisite workmanship and reliable quality.

Second, size specifications

1. Nominal diameter and length

• Considerations : Determine the required nominal diameter and length of the hose according to the actual application scenario.
• Recommendation : Select the appropriate nominal diameter and hose length according to the specific requirements of the piping system. At the same time, consider the length change of the hose in various motion states to ensure that the hose has enough flexibility and flexibility after installation.

2. Bending radius

• Considerations: The bending radius of the hose directly affects its service life and performance.
• Recommendation : Choose a hose with a small minimum bending radius for flexible installation and use in a limited space. At the same time, avoid excessive bending or twisting of the hose during installation.

3. Application scenarios

1. Working environment

• Considerations : including medium temperature, pressure, corrosion and other factors.
• Recommendation : Select the appropriate hose material and pressure level according to the specific requirements of the working environment. For example, in high temperature environments, stainless steel metal hoses that can withstand high temperatures should be selected, and the appropriate pressure level should be determined according to the working pressure temperature correction factor at high temperatures.

2. Nature of medium

• Considerations : The chemical properties of the medium are critical to the selection of hose materials.
• Recommendation : Select the appropriate hose material according to the chemical properties of the medium. For corrosive media, stainless steel with excellent corrosion resistance should be selected.

To sum up, when purchasing stainless steel metal hoses, it is necessary to consider many factors such as material quality, size specifications, and application scenarios. By taking these factors into consideration and selecting the right product, you can ensure that the hose has good performance and reliability during use.
