In determining the type of stainless steel to be chosen, the main consideration is the aesthetic standards required, the corrosivity of the atmosphere in the area, and the cleaning system to be adopted. However, other applications increasingly seek only structural integrity or watertightness. For example, the roof and side walls of industrial buildings. In these applications, the construction cost of the owner may be more important than the aesthetic, the surface is not very clean can also. The use of 304 stainless steel in a dry indoor environment is quite effective.
Q:Can the KBG25 steel tube hold 4 six types of cables?
The specification specifies that the duty ratio of multiple conductors through the pipe laying shall not exceed 20%, and the straight-line distance shall not exceed 30 meters. The distance shall be shortened by the elbow, and the specifications or handbooks can be checked in detail
