The gas transported by the utility model is air or other non spontaneous combustion, non self explosion, non winding, harmless to human body and non corrosive to steel materials. The gas shall not contain viscous substances, and the dust and hard particles shall not be more than 150mg / m3. The gas temperature shall not exceed 80 ° C. Other similar performance can also be selected.
