The deadline is June 1. These 29 standards include the “Code for the Design of Petrochemical Control Roomsâ€, the “Code for the Design of Pumping Zones for Petrochemical Storage and Transportation Systems,†“Specifications for the Design of Petrochemical Water Supply and Drainage Pipelines,†“The Flame Reheating Furnace for General Oil Refining Units,†and the “Petrochemical Pipeline Selected specifications for designing equipment, Specifications for Basic Design of Petrochemical Compressors, Guidelines for the Selection and Selection of High Sulfur Crude Oil Processing Installations and Pipelines, and Specifications for the Construction of Technical Documents for Petrochemical Construction Projects. Simply put, a single luozhu is a luozhu and two star wheels. When the screw is running at high speed, the air pulsation is small and the exhaust volume is large. Due to the force balance of the single screw, the maximum pressure of the first stage compression can be greater than that of the double screw; the single screw is more energy-saving than the double screw, and the bearing size is not as limited as the double screw type and has a longer life.
