Stainless steel needle tubes for manufacturing medical devices Stainless steel tubes for medical devices

The use environment of 304316 stainless steel pipe fittings for medical devices is very special. The disinfectant in the hospital is very corrosive to metal products. Therefore, there are certain standards for material selection. Generally, 18% chromium+8% nickel 30418% chromium+10% nickel 316 stainless steel can ensure that the devices are more resistant to corrosion and have a longer service life.

Part of the industrial pipelines belong to pressure pipelines (the pipelines under the supervision of the technical quality department of the State Market Supervision Bureau), which belong to the pressure pipelines with the most types of industrial pipelines' technological processes, the most complex changes in the production and manufacturing environment, the more types of media transported and the more stringent conditions. See Figure 1 for the scope relationship between industrial pipeline and pressure pipeline.
