What are the differences between luoying rubber joints and metal hoses?
Rubber joints and metal joints are two common pipe connections. Although they work on the same principle, there are some differences in their use and maintenance.
 
Rubber joints are made of rubber, which has good elasticity and wear resistance, and can adapt to the bending, stretching and compression of pipes. They also have good resistance to oil, acid and aging, and have a long service life. Metal joints, on the other hand, are made of metal and have good electrical and thermal conductivity, which can accelerate heat transfer and reduce heat loss. However, the use of metal joints increases the weight and cost of pipes.
 
In terms of installation and maintenance, rubber joints are assembled and vulcanized to ensure that their joints are tight and strong. Metal joints, on the other hand, need to be welded and cut to ensure their electrical and thermal conductivity. While metal joints are somewhat easier to install, they require frequent disassembly and installation, which can increase the cost of use and maintenance.
Therefore, when considering the use of both types of joints, the right solution needs to be selected based on the specific application and the requirements of the piping design. Rubber joints are suitable for high temperature, high pressure and high speed pipelines, while metal joints are suitable for corrosion resistant, high temperature and low pressure pipelines. In practice, the choice and combination of the two depends on the specific application requirements and pipeline design.
