What are the connections of metal hoses?
Metal hose is a kind of packaging material used in food packaging, medical, industrial and other fields, its connection method is crucial for the use and storage of products. Metal hoses are connected in the following ways:
 
1. welding: welding is one of the most common ways to connect the metal hose. The use of welding tools to weld the two ports of metal hose together, this method can ensure that the connection is strong and reliable, and can easily replace the fittings.
 
2. Snap connection: This connection is similar to welding, but more stable than welding, suitable for connecting the body part of the metal hose. The use of snap connection can be metal hose body part and port part fixed together to achieve a good seal and stability. 3. Piercing connection: This connection is suitable for fittings that need to be replaced quickly, such as cameras or fluorescent tubes. Use a tool to pierce one side of the metal hose, then connect the other side of the metal hose to the new fitting.
 
4. Tightening connection: This connection is suitable for parts that need to withstand high pressure, such as lighting and cameras, etc. Use the rising tool to expand the body part of the metal hose, so that it is tightly connected to the port part, thus preventing the entry of liquid or gas.
