Hunan Great Steel Pipe Co., Ltd provides services that reduce total project cost and keep complex piping systems on schedule. Including Cutting, Rolling and Bending, Coating, Beveling, Threading, Welding and Assembly Forming.
Hunan Great Steel Pipe Co,,Ltd,has successfully completed the production and shipment of a batch of customized finned steel tubes for a waste heat recovery upgrade at a petrochemical refinery in Southeast Asia,
Although finned steel tubes consist of a base tube and external fins,their manufacturing process is considerably more complex than their appearance suggests,But two tubes with the same material and dimensions can perform completely differently depending on how they were made,The manufacturing process determines heat transfer efficiency,bond strength,corrosion resistance,and service life,This guide covers how finned steel tubes are manufactured — base tube selection,finning methods,assembly,heat treatment,inspection,and what buyers should verify before ordering,
Plain tubes don't work efficiently when air is the medium,Air-side heat transfer coefficients run 10–100 W,m²·K — compared to 1,000–3,000 W,m²·K for liquids,Finned designs bridge that gap by multiplying surface area 5-15×,
Why spec a finned tube over a plain one? Because air is a terrible heat transfer medium,Plain tubes can't compensate — finned tubes can,by multiplying the external surface area 5 to 15 times,That's why you find them in power plant air-cooled condensers,refinery air coolers,waste heat recovery units,and HVAC evaporator coils,
Proper pipe spool maintenance is essential for extending service life,preventing leaks,reducing unplanned shutdowns,and maintaining the integrity of industrial piping systems,A complete maintenance program typically includes routine visual inspection,corrosion protection,flange and weld inspection,support verification,periodic non-destructive testing (NDT),and maintenance record management,When these practices are performed according to the operating environment and applicable industry standards,pipe spools can deliver reliable performance throughout their design life,
