Finned Tube G Type Heat Ex - Changer Finned Tube For Air Cooler Or Heat Exchanger
G Type Finned Tube
G type embedded spiral finned tube is processed from a certain width in the steel pipe and spiral groove depth, then inlays the ribbon on the steel pipe by the equipment. In winding process, as the pre-tightening force to a certain extent so the strip will be firmly in the spiral groove, to ensure there is a certain contact area between steel band and steel pipe. In order to prevent the strip spring falling off the light tube, the two ends of the steel strip need to weld onto the steel pipe. In order to set easily, there should be a certain clearance between steel belt and spiral groove. If the clearance is too small the setting process will be difficult to proceed smoothly. In addition, the steel belt of winding there will always be a certain amount of rebound, which makes it cannot very good joint among the steel belt and spiral groove bottom. Inlaid fins can be conducted on general equipment, and they cost little.
It use of advanced production equipment by Mcelroy companies in the United States, slotting embedding technology is advanced, from stable, embedded and firm, pulled off force not less than 70 n, the allowable temperature can reach 400 ℃, has the strong ability of temperature resistance and thermal shock, widely used in petrochemical air cooler.Small oil gun (plasma) micro oil ignition warm wind is cold boiler ignition hot air heating equipment in the ball mill coal pulverizing system.
Maximum working temperature:400°C.
Features: High heating efficiency and heating up fast, small volume, small wind resistance, installation is convenient wait for a characteristic, can be installed in a wind pipe and the by-pass pipe.
